POTENTIAL PROBLEMS WITH HFC-134A

This service manual has been written to cover products manufactured with HFC-134A. HFC-134A compressors receive a synthetic based ester oil charge. The hygroscopic (water attraction) property of ester oil is many times greater than the mineral oils previously used with CFC-12. High system moisture causes the formation of acids and alcohol which can damage the compressor. Systems should not be left open for more than fifteen (15) minutes at any time as humidity from the air will enter the system. To ensure system dehydration, the system should be pulled down to 100 microns and vacuum pump oil (mineral oil) must not be allowed to enter the system.

Cleanliness of the system is extremely important. The presence of residues (chlorinated or greasy residues, mineral oil, or impurities) can lead to capillary tube restrictions, oil return problems and compressor damage. Do not use flux on brazed joints.

Check for the latest service related information at ULineService.com. The Technical Knowledge base is continuously updated and can be accessed anytime. Each U-Line product has a unique method of installation, but it is consistent with U-Line’s methods and requirement. Follow the installation guidelines for the U-Line product you are installing.

During the initial one-year warranty period for all U-Line products U-Line shall: (1) at U-Lines option, repair any product or replace any part of a product that breaches this warranty; and (2) for all Marine, RV and Domestic U-Line products sold and serviced in the United States (including Alaska and Hawaii) and Canada, U-Line shall cover the labor costs incurred in connection with the replacement of any defective part. During years two through five of the warranty period for the sealed system, U-Line shall: (1) repair or replace any part of the sealed system that breaches this warranty; and (2) for all Marine, RV and Domestic U-Line products sold and serviced in the United States (including Alaska and Hawaii) and Canada, U-Line shall cover the labor costs incurred in connection with the replacement of any defective part of the sealed system. All other charges, including transportation charges for replacements under this warranty and labor costs not specifically covered by this warranty, shall be borne by you. This warranty is extended only to the original purchaser of the U-Line product. The Registration Card included with the product should be promptly completed by you and mailed back to U-Line or you can register on-line at www.ULineService.com.

The following are excluded from this limited warranty: installation charges; damages caused by disasters or acts of God, such as fire, floods, wind and lightening; damages incurred or resulting from shipping, improper installation, unauthorized modification, or misuse/abuse of the product; customer education calls; food loss/spoilage; door and water level adjustments (except during the first 90 days from the date of purchase); defrosting the product; adjusting the controls; door reversal; or cleaning the condenser.

If a product defect is discovered during the applicable warranty period, you must promptly notify either the dealer from whom you purchased the product or U-Line at P.O. Box 245040, Milwaukee, Wisconsin 53224 or at 414-354-0300. In no event shall such notification be received later than 30 days after the expiration of the applicable warranty period. U-Line may require that defective parts be returned, at your expense, to ULines factory in Milwaukee, Wisconsin, for inspection. Any action by you for breach of warranty must be commenced within one year after the expiration of the applicable warranty period.

This limited warranty is in lieu of any other warranty, express or implied, including, but not limited to any implied warranty of merchantability or fitness for a particular purpose; provided however, that to the extent required by law, implied warranties are included but do not extend beyond the duration of the express warranty first set forth above. U-Lines sole liability and your exclusive remedy under this warranty is set forth in the initial paragraph above. U-Line shall have no liability whatsoever for any incidental, consequential or special damages arising from the sale, use or installation of the product or from any other cause whatsoever, whether based on warranty (express or implied) or otherwise based on contract, tort or any other theory of liability.

Some states do not allow limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages, so the above limitations may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

Section 1 - General Information

PRODUCT LIABILITY POLICY

Field service technicians are authorized to make an initial assessment. If in the servicer’s judgment the damage is the result of a product defect, the product would be removed and returned to U-Line in an unaltered condition. The dealer would then be authorized to permanently replace the end-user’s product at no cost to the end-user. Please call U-Line immediately at 800-779-2547 to initiate the RA and product exchange process.

If in the servicer’s judgment the damage is the result of installation issues (water connection/drain, etc.), the consumer would be so notified and the correction would be made by the servicer or installer without requiring removal of the product. Any claim for damages should be directed to the original installer.

Any U-Line unit involved in an alleged property damage claim must remain unaltered and unrepaired,

for evaluation. No service or repairs should be performed on any unit suspected to be involved in a property damage situation. If a unit has been altered or repaired in the field prior to ULine’s evaluation, any claim for damage may be declined.

If the unit in question is a U-Line CLR or CLRCO with a drain pump, both the unit and the drain pump (regardless of the manufacturer) must be returned to U-Line Corporation.

To complete the damage claim process for the customer, please obtain the following and forward to U-Line at onlineservice@U-Line.com, fax to 414-354-5696 or mail to the address below.

Pictures of the unit, installation and any alleged property damage.

Inquire when the problem first appeared, any prior problems with the product and provide a brief description of the alleged damages.

To expedite the claim process, U-Line will need two damage repair estimates.

Reference the RA number and customer name when providing this information.

If a unit is returned to U-Line, this evaluation will take approximately ten business days. No field service company is authorized to perform this evaluation. When a Return Authorization Number is issued, and the unit has been boxed in a U-Line carton, U-Line should be contacted and then will make arrangements for shipping, or designate a truck line to have the unit shipped freight collect.

If U-Line’s evaluation finds the unit, (or U-Line P60 pump) to be defective, causing the property damage, the damage claim will be reviewed by the U-Line Customer Assurance Department.

If U-Line’s evaluation finds the unit not to be defective, does not repeat a failure or does not leak any water from the U-Line unit or U-Line P60 pump, all claims for damage will be declined.

When a product evaluation is needed, it is the customer’s responsibility to assure that the unit is returned for evaluation. If the customer fails to do so, or has the unit repaired in the field prior to U-Line’s evaluation, any claim for damage will be declined.

WARRANTY CLAIMS PROCEDURE

WHEN SUBMITTING CLAIMS FOR WARRANTY

PAYMENT, PLEASE FOLLOW THESE

GUIDELINES.

You can use any form you would normally use to bill your customer (your own computer generated form, Narda, USA, etc.). Claims can also be filed on-line at www.u-lineservice.com.

The model and serial number MUST be on the claims. Claims will not be paid without a model and serial number.

If you used a part in your repair, you MUST put the part number, the invoice number and where the part came from. Claims will be returned without this information.

If you work on more than one unit per service call please submit a separate claim for each unit.

We track all defects through warranty claims, so please be specific on what the repair was. If it is a system leak, please specify where the leak was.

Please be sure the claim is legible. If the claim form cannot be read, it will be returned, unpaid.

Remember: Door and water level adjustments are 90 day warranties only.

If you are changing out a unit please supply the model and serial number of both units (the unit being replaced and the new unit) and the R.A. number.

Occasionally the customer does not return their warranty cards. In this case we use the date the unit was shipped to our distributor for a beginning warranty date. This may cause the claim to be rejected for a proof of purchase. If you want to check on a purchase date, you may contact the U-Line Corporation Customer Assurance Department at 1-800-779-2547. This will allow you to get a proof of purchase, if needed, before you submit the claim.

At U-Line, parts and labor claims are paid separately. Included in labor are freon and recovery charges, all other parts are handled by the parts department. We require that some parts be returned to us, so we may return them to our vendor. It will be noted on your packing list if we require you to return the part. If a part is to be returned please include a copy of the packing list and a copy of your claim. If the part was purchased at one of our part distributors, you must handle the part warranty with that company. For labor payment please send a readable copy of your claim to U-Line Corporation, P.O. Box 245040, Milwaukee WI, 53224-9540, or fax it to 414-354-

5696. Claims can also be filed on-line at www.u-lineservice.com.

PROOF OF PURCHASE

Proof of Purchase and/or Proof of Install is an important part of the warranty claim process. Sometimes it is difficult to obtain a proper Proof of Purchase/Proof of Install for a number of different reasons:

• The customer does not have a copy (only the original).

• The customer has only their copy of the final Walk Through or sign-off of new construction.

• Other valid reasons that prevent your technician from leaving the job site with a suitable Proof of Purchase/ Proof of Install.

We understand the problem and have modified our Proof of Purchase policy to help you in these situations.

Effective immediately, if a copy of the Proof of Purchase/Proof of Install is not available at the site, the technician should record the following information on the Labor Invoice:

• The name of the selling Dealer

• The date of purchase/installation

• The Order or Invoice number (if available)

• The type of document they saw, i.e. Store Receipt, Closing Papers, Sign-Off of Building Permit, Final Walk Through, etc.

If we have this information on the Labor Invoice, and we have the other information that is needed (correct Serial Number, type of

repair, time spent on repairs, parts used in the repair, invoice number for the part, etc.), we will be able to process the

invoice for you in a timely manner.

Section 1 - General Information

PARTS LISTING

How to Order Replacement Parts

1. Refer to Service Parts and locate the illustration(s) for the model you are servicing.

2. Locate the desired part to be serviced and note the item number assigned to it.

3. Locate the item number within the parts list. Note the full description and the corresponding part number. If this is for a warranty unit, indicate and record the model and serial numbers.

4. When ordering parts, it will be necessary to supply Model Number, Serial Number, Part Number, Part Description and in some cases Color or Voltage.

All warranty parts will be shipped at no charge as long as warranty status has been confirmed. If we require that a part be returned to Uline, you will be informaed at the time the order is placed. It will be noted on your packing list if we require you to return a part or if you may field scrap it. If U-Line requires a defective part to be returned, a prepaid shipping label will be included with your new replacement part. When returning parts enclose a copy of your packing list and a copy of your labor claim, showing the model and serial number, and tag or label the part with the nature of the defect.

Our warranty records may not match the customer's information. In this case, a proof of purchase will be required. If you do not have the proof of purchase at the time the order is placed, the part will be sent net 15 days, charged to a Visa or MasterCard or COD if you don't have an open account with U-Line Corporation. When the proof of purchase is provided, we will credit your account (a check will be sent if the part was sent COD).

5. Parts may be ordered on-line, by FAX or phone:

www.U-LineService.com

Section 2 - Troubleshooting

CLR2160 Model Only:

Concern Response

The cubes are wet. • The storage bin that holds the ice is not refrigerated. The

cubes in the bin are slowly melting down. The bin will maintain a temperature of 32°F to 34°F.

The floor is very warm in front of my unit. • The unit is designed for a built-in application, so warm air

will vent through the front grille, below the door. There is a safety feature built into the control board that will shut down the unit if warm air can’t vent or is restricted.

No ice, but water pours into the trough and down into the drain.

When the unit is turned on, all I get is water fill.

The ice does not come out in a perfect cube shape.

The cubes do not fall into the bin as individual cubes.

Not enough ice is stored in the bin. • Make sure unit is level.

• The standpipe needs to be inserted into the drain hole of the water trough to maintain the proper level of water inside the trough.

• Once the unit is turned on, there will be a three-minute water fill. This ensures a fresh batch of water has filled the trough. If water flows more than three minutes, a service call will be required.

• When the ice is made, a small hole or “dimple” will appear on the front or top of the cube. Increasing or decreasing the time of the freeze cycle will adjust the size of the dimple.

• This is normal. You can use the scoop to break the cubes apart.

Drawer Models Only:

Concern Response

There is excessive condensation on the mullion. • The mullion has a heater behind it that should keep the mullion free of

frost and sweat. In extremely humid conditions, some sweat may appear on the mullion or lower drawer handle/gasket. The heater will not operate in ambient temperatures over 90°F.

• Drawer units should not be used outdoors or in an area that is not airconditioned.

Drawer will not close properly. • The drawer slides have a self-closing feature which engages when the

drawer is about 1” (25.4mm) from being closed. There may be some resistance. If the resistance is hard to overcome, try closing the drawers with more force a couple of times and then try slowly closing the drawers again.

2175DWRR Model Only:

Concern Response

There is a water leak inside the unit. • Make sure the drain is not blocked. Remove any blockage.

OPERATION

CLR2160

GENERAL

Upon initial startup, this unit will enter mode number 5 which is a three-minute water fill regardless of the thermistor temperatures. This only occurs when the initial startup is caused by a power-up of the main board.

Following the three-minute water fill, the unit moves into mode 1 which is the freezing mode. In this mode the water is pumped from the sump trough over the ice maker grid by the circulation pump. This mode typically lasts 10-20 minutes and is regulated by the temperature of the thermistor mounted near the dryer (thermistor 4).

At the conclusion of the freeze cycle the unit will enter mode 2 which is the ice harvest. This harvest can last up to three minutes. During this mode the water trough also refills.

Before the next cycle begins, the custom electronic board determines whether the bin is full. A temperature below 34°F, or a temperature below 35°F for at least one hour will stop the unit from producing ice. The ice-making will always stop at the conclusion of a harvest cycle. It will never stop in the middle of a cycle.

The custom electronic board continuously monitors the optional P60 pump to ensure the drain line is not becoming restricted. In the event of a drain line obstruction, the display interface will show “P1.” If the drain remains restricted the unit will stop ice production until the drain clears. In the event of a partially restricted drain, reduced ice rate will be noticed as the unit continuously turns on and off to eliminate any chances of overfilling the unit with water. If no pump is used the pink jumper needs to be connected to the power cord in its place.

A cleaning mode is available through the user interface by using the key sequence described in the Controls Section. The cleaning mode lasts about 45 minutes, at which point the unit will sit idle for another 15 minutes. During this time the display will show “CL.” At the conclusion of the cycle the unit will automatically turn back on.

THERMISTOR OUTAGE

entering the sequence, keep the COLDER key pressed until you completely release the ON/OFF key for the third time. The display will cycle through a series of numbers to tell which relays are energized. For example, if the unit was in ice-making mode the display would show 11 20 31 40 51 60 70. The first number is the relay number. In the second number, “1” means on and “0” means off. The relay information can be found in the Control Section.

Each relay can also be turned on and off individually to determine whether or not the board and component are operating. If a board is suspected of not operating correctly you can run through this sequence to ensure each component is turning on and off through the board correctly. Go into service mode and choose option #22. This will cycle every relay on and off showing 10 11 20 21 …. If a component fails to turn on when the relay does, you can verify if there is voltage present by using a voltmeter to check the board output.

To view the actual thermistor readings, hold the WARMER and COLDER keys for about five seconds. The display will cycle through the three thermistors and their temperatures. If a thermistor is unused in a unit it will show a “0” reading. The CLR2160 uses thermistors 2 and 4. For thermistor 4 the display will only show up to “99.” In the event the temperature is higher than this the display will show a flashing “99.”

TROUBLESHOOTING

Error Codes

E1, E2, E9 Bad thermistor errors. Replace thermistor. Check

for thermistor errors by accessing “View thermistor # status (2,19, 20, or 21).” If the error code is repeated, the thermistor is open or shorted. If a temperature is displayed, the thermistor is not defective.

P1 Pump circuit is detecting a drain problem. Consult a

plumber to resolve the issue. If unit does not have a P60 installed, then the jumper wire is missing in place of the pump.

Any other error messages will not affect the operation of the CLR2160 model.

After checking the errors be sure to clear the error log by performing service option 12

In the event that a thermistor fails, the unit will stop all functions and display “ER” on the user interface. The exact error can be accessed via the service mode.

SERVICE

The CLR2160 model uses four relays and two thermistors. There is a variety of built-in servicing features to aid in diagnosing the root problem associated with a unit.

To check to see which relays are currently operating, hold the COLDER key and press the ON/OFF key three times. When

TROUBLESHOOTING (CONTINUED)

No ice

Check the ice bin temperature. If the temperature is in the 3435°F range, the unit is shut down due to low temperature inside. This could be caused by low ambient temperatures or running the unit without a water supply attached.

If the ice bin temperature is above 35°F, the unit should be producing ice. Check to ensure the water trough is full and the pump is operating.

Too much ice

Ensure there is Permagum around the thermistor hole. If there is, proceed to the next step.

The control board is equipped with an adjustment to adjust the level of ice in the bin for customer preference or when used in abnormal installations. With ice stacked to the desired level, check the bin temperature by holding WARMER and COLDER for five seconds. We’ll assume the display showed 38°F for this example. Go to service mode #24 and adjust the setting to that number. This will allow the bin to shut off at this ice level. This temperature needs to be checked after the door has been closed for at least 10 minutes in order for the thermistor temperature to stabilize.

Too little ice

If this is a recurring issue, try adjusting service option #24 colder in 1 or 2° increments until the desired level of ice is achieved.

Ice not sized to customer satisfaction

The thickness of the cubes can be adjusted per the ice thickness section of the manual.

Noise

Some noise from this unit is normal. You may hear the sound of ice dropping into the bin, especially when it is empty. The harvesting processes involves flowing refrigerant and water through valves which may produce a rushing type sound during the harvest. The fan and compressor will produce a continuous low motor noise. If installed, the P60 pump will produce noise at regular intervals as it empties water from the unit. If any of these is objectionable, the unit has an Office mode which can be entered for three hours at a time. During this mode the unit will not produce ice; however, the drain pump will continue to operate.

This can be caused by poor incoming water quality. The CLR2160 is designed to produce clear ice in most water; however, abnormal water conditions may result in the need for further filtering.

Water in ice bin

A defect in the drain from the unit will cause water to stop draining from the unit.

Display is showing something other than “Ice,” “ER” or “CL.”

Push one of the keys to see if the display is reset.

Turn unit on and off via the display pad.

Unplug unit, wait one minute and plug back in. If any of these steps return the unit to operation the unit was probably accidently entered into a service mode.

Display is showing a random snaking of characters or a degree symbol is flashing.

The unit is in a special showroom mode. Hold the COLDER key and press the LIGHT key three times to exit.

Display not illuminating but unit operating

First try to plug and unplug the unit. If the display still does not illuminate, there is a four-wire pin connector running from the main board in the base to the display board. One of the wires is disconnected or damaged.

Unit is not operating—no cooling—no fans.

Unplug unit and plug back in. If main board beeps when plugging in the unit then this is most likely a system problem not a board issue.

If board does not beep when plugging in the unit, check the power supply to ensure the outlet is working. Also, check the fuse on the circuit board.

No water in trough

Ensure the standpipe is fully inserted into the trough.

Check the water valve to see if it is filling the unit.

Watch the water flow over the mold to see if excess water is being splashed out of the trough. This could be the result of improper leveling.

Ice does not release from evaporator

This could be caused by improper leveling or the unit is in need of cleaning.

Poor ice quality

Section 3 - Service and Repair

CLRCO2175

GENERAL

The U-Line Model CLRCO2175 combines the best of Échelon refrigeration and clear ice-making capabilities into a single unit. A state-of-the-art microprocessor-based controller simplifies operation and troubleshooting. There are four primary modes of operation:

1. Ice Making and Refrigeration (Figure 2).

2. Ice Making and No Refrigeration (

3. Refrigeration and No Ice Making (

4. Ice Harvest/Water fill (No Refrigeration Possible) (

Figure 5

In addition, there are three sub modes of operation:

5. Off (

6. Water Fill - No Refrigeration (

7. Cleaning (No Refrigeration Possible) (

Review the following notes for general information before reading the schematics.

These are some additional general notes and exceptions:

• The controller has a four-minute compressor minimum off-

cycle regardless of thermistor status, for compressor protection and cycling.

• When making ice, the controller reads liquid line temperature

four minutes into the ice-making cycle to determine the length of that ice-making cycle and subsequent harvest length.

• Once an ice-making cycle is initiated, it will continue through to

harvest regardless of the bin sensor.

• There is a three-minute water fill cycle when the unit is turned

on. Mode 6.

• In order to maintain adequate refrigerator temperature, the

unit will sometimes run in the refrigeration only mode, as shown in Mode 3, even if the ice bin sensor is calling for ice. At the end of each ice harvest, the controller checks the refrigerator sensor and if it is warmer than the higher of 42°F, or the set-point, it will go into refrigeration only mode. The refrigerator must be at 42° or setpoint to make ice continuously. Example:

Setpoint Temperature

Figure 6

Figure 3) Figure 4

Figure 7

Figure 8

or below the sensor. However, after the first slab of cubes is harvested, the controller will follow the logic defined in 5 above and realizing the refrigerator is too warm, will continue in refrigeration only mode (3) until the requirement is satisfied. Thus, upon start-up, the user will see one slab of ice dropped in about 30 minutes, and then there will be no more ice until the refrigerator reaches 42°F or set-point. (This may be two to three hours depending on ambient conditions.)

• There will also be a water fill cycle after the ice bin has been “full” and then calls to make ice again. This can occur when the refrigerator side is off as shown in Mode 6, or when it is on, which is shown in Mode 8. If the refrigerator side is on, when the fill cycle initiates, it will remain on until the fill cycle is completed, even if the refrigerator sensor is satisfied.

• The controller has a four-degree differential designed into it for the refrigerator sensor, such that when it is set to 38°F, the refrigerator will cool until the refrigerator sensor reads 36°F and will not re-initiate refrigerator cooling until the sensor reaches 40°F. So someone monitoring actual temperature (by pressing WARMER momentarily) may see the refrigerator off when the temperature is a degree warmer than set-point, or refrigerator on when it is a degree below set-point. Refer to Echelon Keypad.

• There is no high limit cut-out on this unit; however, if the liquid line sensor were to go out of range (approximately 185°F) the ice maker side of the unit will shut down. The refrigerator will continue to run. When the temperature of the liquid falls back in range, the unit will re-initiate operation. The unit will not normally experience this condition up to 110°F, but conditions such as door openings, heavy loading, restricted airflow, dirty condenser or direct sunlight may contribute to reaching this mode.

• Different from the earlier CLRCO2075, this unit uses two relays to control the refrigeration valves. This means that the valves will only be energized when needed.

• There is now a thermistor on the refrigerator evaporator that will sense the evaporator plate temperature. This will allow the unit to fully defrost based on temperature of the evaporator plate during the defrost modes.

38° 42° or lower ice 38° 45° no ice 55° 55° ice 55° 58° no ice

There is no fill cycle when ice-making re-initiates in this case

because the bin sensor has not been satisfied.

• When the initial three-minute fill cycle is complete, the unit will enter ice making and refrigeration mode (1) if the bin is empty

THERMISTOR OUTAGE

In the event that the condenser thermistor (T4) fails, the unit will stop all functions and display “ER” on the user interface. The exact error can be accessed via the service mode.

If the refrigerator thermistor (T1) fails, the refrigerator will stop operation; however, the ice maker will continue to function. The display will show “ER.” The exact error can be accessed via the service mode.

If the ice bin thermistor (T2) fails, the ice maker will stop functioning; however, the refrigerator will continue to work. The display will show “ER.” The exact error can be accessed via the service mode.

If the refrigerator evaporator thermistor (T3) fails, the unit will function normally; however, defrosting will occur on a timing interval instead of timing and temperature. The display will show “ER.” The exact error can be accessed via the service mode.

SERVICE

The CLRCO2175 model uses seven relays and four thermistors. There is a variety of built-in servicing features to aid in diagnosing the root problem associated with a unit.

To check to see which relays are currently operating, hold the COLDER key and press the ON/OFF key three times. When entering the sequence keep the COLDER key pressed until you completely release the ON/OFF key for the third time. The display will cycle through a series of numbers to tell which relays are energized. For example, if the unit was in ice-making mode, the display would show 11 20 31 40 51 60 70. The first number is the relay number. In the second number, 1 means ON and 0 means OFF. The relay information can be found in the Control Section.

Each relay can also be turned on and off individually to determine whether or not the board and component are operating. If a board is suspected of not operating correctly, you can run through this sequence to ensure each component is turning on and off through the board correctly. Go into service mode and choose option #22. This will cycle every relay on and off showing 10 11 20 21 …. If a component fails to turn on when the relay does, you can verify if there is voltage present by using a voltmeter to check the board output.

To view the actual refrigerator (T1) temperature, hold the WARMER key until the actual temperature is displayed. To view the actual thermistor readings for 2-4, hold the WARMER and COLDER keys for about five seconds. The display will cycle through the three thermistors and their temperatures. If a thermistor is unused in a unit it will show a “0” reading. For thermistor 4 the display will only show up to “99.” In the event the temperature is higher than this, the display will show a flashing “99.”

E1, E2, E7, E8, E9 Bad thermistor errors. Replace thermistor.

Check for thermistor errors by accessing “View thermistor # status (2, 19, 20, or 21).” If the error code is repeated, the thermistor is open or shorted. If a temperature is displayed, the thermistor is not defective.

E3 This will be accompanied by a beep every

minute. This signals that the door has been left open for longer than 20 minutes. Close the door to reset. If the light and display do not go off when the door is closed, check to make sure the magnet is positioned properly.

E5 This signals that the unit has been above set-

point for more than twelve hours by at least 10°. If the unit was just plugged in leave for 24 hours to see if the problem is corrected. If it is not corrected, it is most likely a refrigeration system issue.

E6 This signals that the refrigerator section has

been at least 10° below set-point for at least twelve hours. This would most likely be caused by a bad relay and the circuit board.

P1 Pump circuit is detecting a drain problem.

Consult a plumber to resolve the issue. If unit does not have a P60 installed, then the jumper wire is missing in place of the pump.

After checking the errors, be sure to clear the error log by performing service option 12.

No ice

Check the ice bin temperature. If temperature is in the 34-35°F range the unit is shut down due to low temperature inside. This could be caused by low ambient temperatures or running the unit without a water supply attached.

If the ice bin temperature is above 35°F the unit should be producing ice. Check to ensure the water trough is full and the pump is operating. If the components are not operating, see the service section above.

In the general section the methods to enter some other service modes are available. For the CLRCO2175 model some useful modes are the ICE MAKER OFF MODE, FORCED REFRIGERATOR DEFROST, ICE THICKNESS ADJUST, CLEAN, AND TEMPORARY SHUTDOWN MODE. These can be useful in servicing the unit.

GENERAL

Refrigerant is pumped from the compressor to the condenser as a high pressure, high temperature vapor.

As the refrigerant cools in the high pressure condenser, the vapor condenses to liquid. During this phase change, a great amount of heat is rejected with the help of the condenser fan.

The liquid then flows to the dryer where it is strained and filtered.

From the dryer, the refrigerant flows through the capillary tube which meters the liquid refrigerant to the evaporator. The

pressure of the refrigerant is reduced to the evaporating or low side pressure.

The reduction of pressure on the liquid refrigerant causes it to boil or vaporize until it reaches saturation temperature. As the low temperature refrigerant passes through the evaporator coil, it continues to absorb a lot of heat, causing the boiling action to continue until the refrigerant is completely vaporized. It is during this phase that the most heat is absorbed (the cooling takes place) in the refrigerator.

The refrigerant vapor leaving the evaporator travels through the suction line to the compressor inlet. The compressor takes the low pressure vapor and compresses it, increasing both pressure and temperature. The hot high pressure gas is pumped out the discharge line and into the condenser. The cycle continues

REVIEW THE FOLLOWING NOTES FOR GENERAL INFORMATION.

• The unit is equipped with a four-minute compressor-off cycle.

• The mullion heater is energized on the 2175DWRR whenever the

Normal defrosting is based on a time and temperature scale. See chart on page 3-40. Defrost ends if evaporator thermistor reaches stop point or maximum time, whichever comes first.

THERMISTOR OUTAGE (EXCEPT DWRWS & 2275ZWC):

If the refrigerator thermistor (T1) fails, the unit will continue to operate based on a preset time interval of 10 minutes on and 30 minutes off. The display will show “ER.”

If the evaporator thermistor (T2) fails, the unit will operate except it will defrost solely on time and ignore the temperature reading. The display will show “ER.” If the ambient thermistor (T3) fails, the unit will always have the mullion heater energized. The display will show “ER.”

THERMISTOR OUTAGE (DWRWS & 2275ZWC)

T3 temperature falls below 90°F.

Figure 10. 2275DWRWS/2275ZWC

If T1 is not working, unit runs a preset time interval — 10 minutes ON, 60 minutes OFF.

If T2 is not working, unit runs a preset time interval — 10 minutes ON, 60 minutes OFF.

If either T3 or T4 is open, use 90 minutes for defrost length. These errors do not show on the display; they are only logged on the board.

SERVICE

To check to see which relays are currently operating, hold the COLDER key and press the ON/OFF key three times. When entering the sequence, keep the COLDER key pressed until you completely release the ON/OFF key for the third time. The display will cycle through a series of numbers to tell which relays are energized. For example, if the unit was cooling the bottom drawer the display would show 11 20 31 40 50 61 70. The first number is the relay number. In the second number, 1 means ON and 0 means OFF. The relay information can be found in the Control Section.

Each relay can also be turned on and off individually to determine whether or not the board and component are operating. If a board is

3-15

Section 3 - Service and Repair

suspected of not operating correctly, you can run through this sequence to ensure each component is turning on and off through the board correctly. Go into service mode and choose option #22. This will cycle every relay on and off showing 10 11 20 21 …. If a component fails to turn on when the relay does, you can verify if there is voltage present by using a voltmeter to check the board output. 1 means ON and 0 means OFF.

In the general section the methods to enter some other service modes are available.

TROUBLESHOOTING:

Error Codes

E1, E2, E7,

E8 & E9 Bad thermistor errors. Replace thermistor. Check for

thermistor errors by accessing “View thermistor # status (2, 19, 20, or 21).” If the error code is repeated, the thermistor is open or shorted. If a temperature is displayed, the thermistor is not defective.

E3 This will be accompanied by a beep every minute. This

signals that the door (or bottom drawer) has been left open for longer than 20 minutes. Close the door to reset. If the light and display do not go off when the door is closed, check to make sure the magnet is positioned properly.

E5 This signals that the unit has been above set-point for

more than twelve hours by at least 10°. If the unit was just plugged in, leave for 24 hours to see if the problem is corrected. If it is not corrected, it is most likely a refrigeration system issue.

E6 This signals that the refrigerator section has been at

least 10° below set-point for at least twelve hours. This would most likely be caused by a bad relay and the circuit board.

During the forced defrost no heating will occur. This is just a prolonged off cycle.

Noise

Some noise is normal such as a hum from the fans/compressor.

Display is showing something other than “SP (38)” or “ER.”

Push one of the keys to see if the display is reset.

Turn unit on and off via the display pad.

Unplug unit, wait one minute and plug back in. If any of these steps returns the unit to operation, the unit was probably accidently entered into a service mode.

Display is showing a random snaking of characters or a degree symbol is flashing.

The unit is in a special showroom mode. Hold the COLDER key and press the LIGHT key three times to exit.

Display not illuminating but unit operating

Unit is not operating—no cooling—no fans.

Unplug unit and plug back in. If main boards beeps when plugging in the unit then this is most likely a system problem, not a board issue.

If board does not beep when plugging in the unit, check the power supply to ensure the outlet is working. Also, check the fuse on the circuit board.

Refrigerator too warm

Check the actual refrigerator temperature. If set to 38°F, the actual temperature should be between 36°F and 40°F during normal operation. Recent door openings, product loading or defrost cycles will push the temperature higher for short time periods.

E10 This will be accompanied by a beep every minute. This

signals that the top drawer has been left open for longer than 20 minutes. Close the door to reset. If the light and display do not go off when the door is closed, check to make sure the magnet is positioned properly.

After checking the errors, be sure to clear the error log by performing service option 12.

Excessive Frost on evaporator

Force a defrost cycle via the keypad input or shut down unit and thaw if frost is very thick. If the evaporator clears, it was due to some type of abnormal operation. If the unit will continue to be used in this manner, the defrost length can be lengthened in the service menu to prevent future issues. Extending this length may be detrimental to the refrigerator temperature. During very long defrosts the temperature may raise higher than desired.

THERMISTORS

Three or four thermistors are employed. All are of the type 2. These measure the refrigerator, freezer, ice maker, or evaporator drain pan.

REED SWITCH

A reed switch is mounted to the underside of the cabinet and a magnet is mounted to the door. When the door is closed the magnet trips the switch which turns the light and display off.

For the CO2175DWR model there is a second reed switch mounted on the inside rear left corner of the top drawer.

Both drawers are monitored individually; however, when either drawer is opened both cabinets light and the displays energize.

DEFROST

Condensate drains down trough under evaporator, into drain pan, and into condensate pan through drain hose. The drain trough is warmed during defrost by contact with evaporator fins and drain heater attached to the drain pan.

ULIN_0370_A

These units defrost on time and temperature. The Defrost Cycle runs for a minimum of 18 minutes (adjustable), and stops at a maximum of 45 minutes or when T4 reaches 42°F (nonadjustable), whichever comes first.

WARNING

ICE MAKER

DO NOT cycle ice maker by hand. This will cause damage to the ice maker.

Freeze cycle

• Neither ice maker relay is energized.

• Unit is cooling down to 15°F set-point.

• The unit may cycle on and off as the ice maker is pulling down to maintain the proper refrigerator/freezer temperatures.

• The minimum freeze time as permitted by the board is 20 minutes (CO2175F) or 75 minutes (CO2175DWR).

Harvest cycle 1

• Relay 6 is energized for 30 seconds and relay 7 is energized for 10 minutes. The bin arm must be fully lowered and the lower drawer closed for this cycle to begin.

Harvest cycle 2

• The lower drawer must remain closed for the cycle to continue. In the event that it is opened the timers will hold until the drawer is closed. At that time they will resume the cycle. If the unit has a door rather than a drawer it is not effected.

• Relay 6 is now off and the ice maker is powered completely by relay 7. This occurs at approximately the 2 o'clock position.

• Ejector blades stall on the ice until the heater releases it from the mold.

• This cycle will last a few minutes.

Water fill cycle

• At about the 10 o'clock setting the water valve is energized for about 7 seconds to refill the mold.

• At the conclusion of the cycle the blades stop at the 12 o'clock position.

Harvest cycle 3

• Following the water fill relay 7 remains energized for the balance of the 10 minutes that it needs to remain on.

Storage mode

• The bin arm is in the UP position, either held in place by the ice or manually raised. The board continues to signal the ice maker to harvest so relays 6 and 7 will energize; however, with the arm up the cycle will not begin.

Review the following notes for general information before reading the schematics.

These are some additional general notes and exceptions:

• The unit is equipped with a four-minute compressor off cycle.

• The controller is designed to be able to show and set the refrigerator set-point. Based on this input the controller tries to maintain the perfect balance of refrigeration to keep the refrigerator and freezer at acceptable temperatures. For this reason the refrigerator temperature may fluctuate from 34°F to 40°F depending on the freezer load. The freezer will also float in a -10 to +10 range depending on the refrigerator load and usage.

• The ice harvest will be initiated when the ice maker temperature drops to 15°F. Through a built-in timer the ice maker can only harvest once every 20 minutes (for CO2175F) or 75 minutes (CO2175DWR) at a maximum so if the temperature is at 15°F it will not necessarily cycle depending on when the previous cycle had occurred.

• The drain pan heater will energize five minutes before and after the hot gas portion of the defrost cycle (not on CO2175DWR). This time is not included in the defrost total length.

• If the unit is turned off while the ice maker is in a harvest mode, the display will flash OFF while the ice is harvesting — up to 10 minutes.

THERMISTOR OUTAGE

If the refrigerator thermistor (T1) fails, the unit will continue to operate based on the freezer temperature. Cycle lengths and temperatures may not be exact; however, this will prevent the loss of perishables. The display will show “ER.” The exact error can be accessed via the service mode.

If the ice maker thermistor (T2) fails, the unit will operate except it will not produce ice. The display will show “ER.” The exact error can be accessed via the service mode.

If the freezer thermistor (T3) fails, the unit will continue to operate based on the refrigerator (T1) temperature. Cycle lengths and temperatures may not be exact; however, this will prevent the loss of perishables. The display will show “ER.” The exact error can be accessed via the service mode.

If the pan thermistor (T4) fails, the unit will operate normally; however, the defrost will take place on time only rather than time/ temperature. The display will show “ER.” The exact error can be accessed via the service mode.

SERVICE

To check to see which relays are currently operating, hold the COLDER key and press the ON/OFF key three times. When entering the sequence, keep the COLDER key pressed until you completely release the ON/OFF key for the third time. The display will cycle through a series of numbers to tell which relays are energized. For example, if the unit was in ice-making mode the display would show 11 20 31 40 51 60 70. The first number is the relay number. In the second number, 1 means ON and 2 means OFF. The relay information can be found in the Control Section.

In the general section the methods to enter some other service modes are available. For these models some useful modes are the ICE MAKER OFF MODE, FORCED ICE MAKER HARVEST, and FORCED REFRIGERATOR DEFROST. These can be useful in servicing the unit.

E1, E2, E7, E8, E9 Bad thermistor errors. Replace thermistor.

E3 This will be accompanied by a beep every

minute. This signals that the door (or bottom drawer) has been left open for longer than 20 minutes. Close the door to reset. If the light and display do not go off when the door is closed check to make sure the magnet is positioned properly.

E5 This signals that the unit has been above set-

point for more than twelve hours by at least 10 degrees. After repair is completed, leave for 24 hours to see if the problem is corrected. If it is not corrected, it is most likely a refrigeration system issue.

E6 This signals that the refrigerator section has

been at least 10 degrees below set-point for at least twelve hours. This would most likely be caused by a bad relay and the circuit board.

After checking the errors be sure to clear the error log by performing service option 12.

Not making ice

The ice maker needs to be down to 15°F before initiating a harvest. If above 15°F, the unit is not cooling properly or has not been plugged in for a sufficient period of time.

The CO2175DWR model will only harvest ice with the lower drawer closed.

To check the operation of the circuit board and the ice maker, force an ice harvest through the keypad input. During this time you can check to see if the blades rotate, if they stop anywhere, if the water valve opens, etc.

Section 3 - Service and Repair

Too much ice

Ensure the bin arm is correctly moving during an ice production cycle and that it can touch the top of the ice. If not, the arm may have been bent.

Excessive frost on evaporator

Force a defrost cycle via the keypad input. If the evaporator clears it was due to some type of abnormal operation. If the unit will continue to be used in this manner the defrost length can be lengthened in the service menu to prevent future issues. Extending this length may be detrimental to the freezer section by causing food to melt or ice to fuse more easily.

During the forced defrost, if no heating occurs, check the hot gas coil and heater for voltage and resistance.

Noise

These are frost-free units with two fans, compressor, and two solenoid valves. Some noise is normal such as a hum from the fans/ compressor. Also, during an ice harvest it is normal to hear water filling the mold and cubes dropping into the bucket.

Poor ice quality

This can be caused by poor incoming water quality.

Refrigerant is pumped from the compressor to the condenser as a high pressure, high temperature vapor.

As the refrigerant cools in the high pressure condenser, the vapor condenses to liquid. During this phase change, a great amount of heat is rejected with the help of the condenser fan.

The liquid then flows to the dryer where it is strained and filtered.

From the dryer, the refrigerant flows through the capillary tube which meters the liquid refrigerant to the evaporator. The pressure of the refrigerant is reduced to the evaporating or low side pressure.

OPERATING ENVIRONMENTAL/ CLIMATE CONTROL REQUIREMENTS

For All - Except WC, ADA, DWRWS, BEV Center, CODWR & Dual Zone(Z)

Many U-Line models are designed to operate in harsh outdoor/ marine environments. Special considerations include the following:

• The units are designed to operate between 50°F (10°C) and 110°F (40°C). High ambient temperatures (110°F or higher) may reduce the unit's ability to reach low temperatures and may also reduce the ice production rate for those models with icemakers.

• If the ambient temperature is expected to drop below 45F, drain all water from the unit to prevent freezing damage not covered by the warranty.

• For best performance, keep the unit out of direct sunlight and away from heat generating equipment.

• For best performance and life outdoors, place under a counter or provide shelter of some kind.

• In climates where high humidity and dew points are present, condensation may appear on outside surfaces. This is considered normal. The condensation will disappear when the humidity drops.

VIEWING ACTUAL TEMPERATURE

- ALL MODELS EXCEPT 2275DWRWS/2275ZWC/

2275ZWCOL

There are two modes to view temperature. In viewing temperature in these modes, any offsets are taken into account. This means that if you place a thermistor in a known temperature, let’s say ice water, it may not read the 32°F that you would assume. If the control offset was preset at -3°F while you placed the thermistor in an icebath, the actual thermistor reading when viewing actual temperature would read 35°F. In the unit this would cause the cabinet to push itself 3° cooler. To view pure thermistor readings, you must go into the service menu and choose the correct option.

To view T1 (normally refrigerator temperature) hold the WARMER key for approximately five seconds until the “F” flashes. Release and the display will show the corrected refrigerator temperature. For Wine Cooler models the display will cycle through all three zones. These temperatures are approximate and calibrated for a cabinet in normal ambient temperatures with some product load. Checking a completely unloaded cabinet may result in other temperatures. Not

DANGER

IMPORTANT

ORIGINS ELECTRONIC CONTROL

Origins Keypad Options

Electrocution can cause death or serious injury. Burns from hot or cold surfaces can cause serious injury. Take precautions when servicing this unit.

• Disconnect the power source.

• Do not stand in standing water when working around electrical appliances.

• Make sure the surfaces you touch are not hot or frozen.

• Do not touch a bare circuit board unless you are wearing an anti-static wriststrap that is grounded to an electrical ground or grounded water pipe.

• Handle circuit boards carefully and avoid touching components.

NOTE: When touching key combinations in which you hold one key and press another three times it is important to carefully follow the procedure.

1. Hold the desired key.

2. Press the other key three times.

3. Release the held key only after releasing the touched key for the

third time.

Except as noted, these functions are available on all models.

ON/OFF

CABINET LIGHT

On units with glass doors, touching the LIGHT key will turn on the cabinet light for four hours at a time. Touching the key again will turn the light off. Using the cabinet light for more than four hours may be detrimental to the cabinet temperature and product. Only available

on 1175BEV, 1115WC and 1175WC models.

This does not apply to ADA24R glass door units. The light and display are always off when the glass door is closed.

VIEWING ACTUAL TEMPERATURE

In viewing temperature in these modes any offsets are taken into account. This means that if you place a thermistor in a known temperature, let’s say ice water, it may not read the 32°F that you would assume. If the control offset was preset at -3°F while you placed the thermistor in an icebath, the actual thermistor reading when viewing actual temperature would read 35°F. In the unit this would cause the cabinet to push itself 3° cooler. To view pure thermistor readings you must go into the service menu and choose the correct option.

To view the thermistor temperature, hold the WARMER key for approximately five seconds until the “F” flashes. Release and the display will show the corrected refrigerator temperature. For Wine Cooler models the display will cycle through all three zones. These temperatures are approximate and calibrated for a cabinet in normal ambient temperatures with some product load. Checking a completely unloaded cabinet may result in other temperatures.

CHANGING FROM FAHRENHEIT TO CELSIUS

To change the displayed temperature from °F to °C, hold the LIGHT key and press COLDER three times. This will change all values to °C. When the key combination is accepted the control will change values.

SHOWROOM MODE

This mode is designed to show units in a display environment. When in this mode the only functions will be the control and cabinet lights. The compressor, fans, etc. will not operate. To enter this mode hold the COLDER key and press the LIGHT button three times. Once entered, the degree symbol will begin to flash. When the degree symbol is flashing the unit will allow the use of the control for demonstrations. After not touching the unit for one minute the display will begin to “snake” around. This is meant to alert you the unit is in showroom mode. The unit can be left in this mode indefinitely. If you again want to demo the control, touch any key and the degree symbol will begin to flash. To exit this mode: This mode needs to be exited by the same key combination as used to enter the mode.

SERVICE MODE

This mode has 16 different options available for service diagnostics. To enter the mode hold the WARMER key and press the LIGHT button three times. The display will show “0.” When in this mode the WARMER and COLDER keys will act as up and down arrows to select the desired option. The LIGHT key is the ENTER key and will enter a function. If changing a setting, you must press the LIGHT key again to retain the changed setting. To exit the service mode scroll to option 99 and press the LIGHT key. After five minutes of not touching any keys the mode will also exit automatically.

Adjusting the Set-point

To adjust the set-point press and release either the WARMER or COLDER key. This will start the set-point flashing. While in this mode you can adjust the set-point warmer or colder until the desired temperature is reached. The factory recommended set-point is 38°F for refrigerators/refrigerator-freezers and 50°F for wine coolers. When adjustment is complete stop touching the display and the setpoint will be saved in approximately five seconds.

1. Light all LED segments

This will illuminate all the LEDs on the board to ensure they work properly.

2. Thermistor 1 status—Temperature, E1, or E2

This will show the pure thermistor reading with no offsets taken into account. When placed in ice water this thermistor should read 32°F in this menu option.

3. Error log

A list of the errors in the order they occurred will scroll once on the display. Repeat if desired. Once viewed perform option 12 to clear the errors from memory.

4. Defrost information

Displays the number of defrosts that have occurred in the past 24 hours.

5. Compressor runtime based on last cycle

This will show the number of minutes the compressor has run in the prior cycle (or current cycle if the compressor was running when service mode was entered).

6. Defrost length adjust min—99 minutes

The length of the defrost can be adjusted up to 99 minutes long (for every six hours). The other defrost parameters still apply. Lengthening a defrost may cause higher than normal temperatures in the refrigerator section.

7. Light switch 1 status—0 or 1

8. Display toggle status—0 or 1

This will tell if the display should turn off with the door switch or not. At the “0” reading the light should be off with the door closed and on with the door open. At the “1” reading the light stays on always.

9. Restore factory defaults

This will restore the default set-point, defrost and offset values.

10. Adjust thermistor 1 offset—10 to +10F

This allows calibration of the sensor to cabinet for abnormal operations. By adjusting this number colder you can change the average cabinet temperature to a colder value.

The U-Line ADA24R models employ both a 12VDC evaporator fan assembly and condenser fan assembly. The motors are powered by a 12VDC power supply located in the base of the unit. These fans are designed to operate in conjunction with the compressor and should be running whenever power is applied to the compressor electricals. These motors do not require external lubrication and do not overtighten the mounting screws upon installation (tab breakage could occur).

Leveling

It is extremely important that the unit is level for maximum production.

If it is not:

Doors or drawers will not work properly.

In ice maker units, uneven sized cubes will be formed. Ice production will reduce and water spilling into the storage area can occur causing the ice in the bin to melt prematurely (Figure 32).

Remember, floors surrounding a drain have a tendency to slope toward the drain.

1. Use a level to check the unit from front to back (Figure 33) and from side to side (Figure 34).

2. If the unit is not level, adjust the feet on the corners as necessary

(Figure 35)

Check after each adjustment and repeat the previous steps as necessary until the unit is level.

. Rotating the feet clockwise raises the unit.

INTERVAL - AS REQUIRED

Ice thickness adjustments are made using the control panel as follows:

1. To enter the thickness adjustment mode:

a. Touch and hold the UP ARROW button. b. Touch and release the DOWN ARROW button three times,

then release the UP ARROW button.

c. The display will switch to “0” to confirm the thickness

adjustment mode has been selected.

2. The factory setting is “0,” and the total range of adjustment is -5 to +5 (ideal range is -1 to +1). Use the UP ARROW button to raise the setting and thicken the ice bridge, or the DOWN ARROW button to lower the setting to thin the ice bridge.

Sample area

ULIN_0063_A

Figure 56

Ice thickness adjustment should only be made one increment at a time. Allow ice maker production to stabilize for 24 hours before rechecking ice thickness.

3. Touch and release the LIGHT button key to exit the ice thickness adjustment mode.

4. Remove all ice from the storage bin.

Ice cubes in any given batch will vary, so it is necessary to choose cubes from the sample area for comparison when making adjustments. If further adjustments are desired, repeat Steps 1 through 4.

The ice cube thickness is factory set for best overall performance. The factory setting is designed to maintain an ice bridge of approximately 1/16" to 1/8" under normal conditions resulting in a dimple of approximately 1/4" to 1/2" in depth. A fuller cube with less of a dimple results in a thicker ice bridge. As the ice bridge becomes thicker, the tendency for the cubes to stay together as a slab increases. A bridge thicker than 1/8" may cause cubes to overfill the ice bucket.

Plumbing - CLR2160 and CLRCO2175

Plumbing installation must observe all state and local codes. All water and drain connections MUST BE made by a licensed/qualified plumbing contractor. Failure to follow recommendations and instructions may result in damage and/or harm.

DRAIN CONNECTION

Drain can NOT be located directly below unit. Unit has a solid base that will not allow unit to drain below itself.

The unit can be installed using a gravity drain, a factory-installed drain pump (U-Line P60) or a locally installed drain pump. Drain lines must have a 5/8" inside diameter. The floor drain must be large enough to accommodate drainage from all attached drains.

Follow these guidelines when installing drain lines to prevent water from flowing back into the ice maker storage bin and/or potentially flowing onto the floor, causing water damage:

GRAVITY DRAIN

A Gravity Drain may be used if:

• Drain line has at least a 1" drop per 48" of run (1/4" per foot).

• Drain line does not create traps or created traps are vented (Figure 62).

2. Attach the other end of the rigid tube to your 5/8" ID drain line with a worm clamp.

3. Insulate the drain line, if necessary, to prevent condensation.

FACTORY-INSTALLED DRAIN PUMP

If your drain line will run up to a stand pipe, disposal assembly or spigot assembly or does not otherwise meet the requirements for a gravity drain, you may have ordered the CLR2160 with a U-Line P60 drain pump. See Figure 64, Figure 65 and Figure 66 for typical installations requiring a drain pump. If you need to install a P60 drain pump into your unit, see Locally-Installed Drain Pump.

3. Remove 12 screws and back panel.

Back panel serves as a guard. DO NOT put your hands inside the ice maker cabinet or attempt to touch any components except the discharge tube during testing. Failure to follow this warning could result in serious personal injury or death.

Before installing your U-Line unit with factory- installed ULine P60 pump, it is extremely important to check and test all hose connections at the drain pump. There is a possibility that hose connections may have loosened during shipment.

To prevent accidental electrocution, make certain that the floor surfaces surrounding the unit are dry whenever power is removed from, or applied to, the unit.

To check and test hose connections:

1. Make certain the unit is not plugged into an electrical outlet.

2. Carefully push the power cord grommet through the hole in the back panel

(Figure 67)

4. Check that the clamps and hose connections are tight at the following areas

(Figure 68)

• Discharge tube (A)

• Drain tube (B)

• Vent tube (C)

Figure 68

5. Place a suitable container beneath the pump’s discharge tube. (The bucket must be able to hold a minimum of one gallon.)

6. Plug the ice maker power cord into a properly grounded, polarized electrical outlet.

7. Verify pump operation by pouring one gallon of water into the ice storage bin of the ice maker. The pump should energize and pump the water into the container.

8. At this time, verify that all tube and clamp connections are tight and leak free.

Section 3 - Service and Repair

2. Attach the other end of the rigid tube to your 5/8" ID drain line with a worm clamp.

3. Insulate the drain line, if necessary, to prevent condensation.

LOCALLY-INSTALLED DRAIN PUMP

If a gravity drain connection is not possible, and you have not purchased the CLR2160 with factory-installed pump, we strongly recommend the use of the U-Line P60 drain pump. The U-Line P60 drain pump is available through your dealer, or direct from U-Line with complete installation instructions. If a pump other than the ULine P60 drain pump is to be used, it must meet the following specifications:

• It must be UL listed and have a UL listed, 120 VAC,

3-wire grounded power cord.

• It must have overall maximum outside dimensions of

8-3/4" wide x 5-3/4" deep x 7-3/4" high.

• It must have a minimum flow rate of 15 gallons per hour at 10 feet

of lift.

• It must have a sealed sump which does not allow water leakage in

the case of a power outage, restricted drain or pump failure.

• It must have a check valve in the discharge line to prevent waste

water return to the pump.

• It must have an overflow protection control which will shut off

power to the ice maker in the event of a pump failure.

• It must have an operating temperature range of 50°F to 110°F

(10°C to 40°C).

U-CLR DRAIN KIT (AVAILABLE FOR PURCHASE)

Tools Required

• 1/4" Nut driver or flat 5/16" screwdriver

• **(1) 5/8" to 7/8" adapter

** Depending on your model, your unit may have been packaged with these items. If you need to order these items, please contact U-Line and order Part # U-CLRDRAINKIT.

NOTE: These instructions are based on the U-Line recommendations and common industry practice. You must consult your local plumbing codes to ensure compliance. U-Line requires the use of copper cold water supply connection tubing. Plastic tubing should not be used.

1. Locate the desired cold water supply location. Attach a 1/4" copper line to this location and route the tubing to the appliance. Leave approximately 8' of water line to be coiled behind the appliance as shown (Figure 69). This water line should be looped into 2 coils. This will allow the line to flex when moving the appliance in and out of the opening.

Figure 69

2. Locate the U-Line supplied garden hose fitting. Ensure the end of the copper tubing has been cut straight and is free of burrs. Slide the compression nut and ferrule onto the copper tubing as shown

3. Your U-Line icemaker requires a drain connection. This unit can be purchased with or without a factory-installed drain pump.

If a pump is not installed in the appliance you must use the gravity drain style installation

OR install a pump per the

installation instructions found on www.U-Line.com.

4. Slide two hose clamps onto the drain connection on the rear of the appliance. Insert the barbed fitting half-way into this connection. On the other end of the barbed fitting attach the 5/8" braided tubing. Slide a clamp onto each side of the barbed fitting as shown

(Figure 71 & 70)

Figure 72

5. Determine the location of your drain and begin to route the drain tubing in that direction. If using the gravity drain option you must provide 1/4" drop every foot of line. For drain pump application you must not go higher than 10 feet of lift. The lift should be made vertically at the beginning of the drain line. After the lift try and provide 1/4" drop every foot of line to the drain location.

6. Connect the water supply fitting by screwing the brass garden hose fitting to the water valve in the rear of the unit. Tighten this fitting with a pliers. Do not use Teflon tape or joint compound on the fitting. The rubber washer provides an adequate seal. Other materials could cause blockage of the valve. The copper water line should now be clamped to the rear of the unit to prevent rotation when sliding in. Remove the clamp from the unit, slide the tube into it and reattach using the 1/4" nut driver as shown

and 70)

(Figure 71

7. Plug in the unit and put the unit into OFF mode by holding the power key for 10 seconds. Not doing this will cause the unit to fill with water for three minutes.

8. Turn on the water supply and ensure the connections are free of leaks.

9. Begin to push the appliance into the desired cabinet opening. The copper tubing should remain in two coils behind the unit. While pushing the unit into the opening continuously reroute the drain tube to avoid kinks. The most common installation pulls the slack into an adjacent cabinet or basement area. Again, if installing a gravity drain, ensure you provide proper slope

10. Once pushed completely into the opening finish routing the drain tubing to the desired location. Common installations use a floor drain, standpipe, garbage disposal, or Y-branch tailpiece-type drain connection

(Figure 73 - 76)

. After the installation is complete, check the unit to ensure it is level both side to side and front to back. For disposal connections an optional adapter may be required (included with the kit) to adapt from the 7/8" connection.

11. For the gravity/floor drain or the standpipe drains it is important to secure the drain tubing to those items to prevent it from coming loose. For the disposal or Y-branch tailpiece connections press the drain tube over the barbed end on the connector. Make sure the knockout inside the tailpiece has been removed for both types of connections. Attach these two with a worm drive hose clamp. Depending on the size of the Y-branch or disposer fitting an adapter may be needed to interface between the 5/8" hose and connection.

12. After all connections have been completed turn the unit to the ON position. Pour one gallon of water into the ice bin and check all drain connections for leaks. During this time also ensure that the water flows from the bin. If the water does not flow from the bin there may be a problem with the drain connection such as kinks or improper slope. If your unit has a drain pump an indicator of P1 on the display will alert to a slow or clogged drain. If any problems are found, retrace the drain connection, correct the issue and retest with water.

WATER SUPPLY CONNECTION

When connecting the water supply, follow these guidelines:

• Review the local plumbing codes before you install the unit.

• Connect to the cold water supply.

• The water pressure should be between 20 and 120 psi.

• The water line MUST have a shut-off valve in the 1/4” O.D. supply line.

• Leave approximately 8’ of water line to be coiled behind the appliance (Figure 77). The water line should be looped into 2 coils. This will allow the unit to be removed for cleaning and servicing. However, make certain that the tubing is not pinched or damaged during installation.

U-Line recommends the use of copper tubing for installation or using flexible water supply kit from U-Line, Part No. WATERHOOKUP.

If using the flexible water supply kit, follow the instructions included with the kit.

To connect to 1/4” copper line water supply:

1. Locate the desired cold water supply location. Attach a 1/4”

copper line to this location and route the tubing to the appliance. Leave approximately 8’ of water line to be coiled behind the appliance. The water line should be looped into 2 coils. This will allow the line to flex when removing the unit for cleaning and servicing (Figure 77).

2. Locate the U-Line supplied garden hose fitting. Ensure the end of the copper tubing has been cut straight and free of burrs. Slide the compression nut and ferrule onto the copper tubing as shown

Figure 78

Use this appliance for its intended purpose only and follow these general precautions along with those listed throughout this guide:

U-LINE CORPORATION LIMITED WARRANTY

PRODUCT LIABILITY POLICY

SERIAL NUMBER FORMAT

The serial number is divided into four segments. A typical serial number is 0914997-11-0005.

The first two digits of the first segment, 09, represents the year the unit was made.

The next four/five digits of the first segment, 14997, represent the shop order number. Order number 14997 is assigned for the Model CLRCO2175B-40 units.

The next two digit segment, 12, represents the month the unit was made.

The last four digit segment, XXXX, is a factory internal control number used at U-Line Corporation.

You can use any form you would normally use to bill your customer (your own computer generated form, Narda, USA, etc.). Claims can also be filed on-line at www.u-lineservice.com.

The model and serial number MUST be on the claims. Claims will not be paid without a model and serial number.

If you used a part in your repair, you MUST put the part number, the invoice number and where the part came from. Claims will be returned without this information.

If you work on more than one unit per service call please submit a separate claim for each unit.

We track all defects through warranty claims, so please be specific on what the repair was. If it is a system leak, please specify where the leak was.

Please be sure the claim is legible. If the claim form cannot be read, it will be returned, unpaid.

Remember: Door and water level adjustments are 90 day warranties only.

If you are changing out a unit please supply the model and serial number of both units (the unit being replaced and the new unit) and the R.A. number.

Proof of Purchase and/or Proof of Install is an important part of the warranty claim process. Sometimes it is difficult to obtain a proper Proof of Purchase/Proof of Install for a number of different reasons:

We understand the problem and have modified our Proof of Purchase policy to help you in these situations.

Effective immediately, if a copy of the Proof of Purchase/Proof of Install is not available at the site, the technician should record the following information on the Labor Invoice:
