Potential Problems With HFC-134A

This Service Manual has been written to cover product manufactured with HFC-134a. HFC-134A compres­sors will be received with a synthetic based ester oil charge. The hygroscopic (water attraction) property of
ester oil is many times greater than that of 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 system. To
assure 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 will be 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. Flux must not

be used on brazed joints.

LIMITED WARRANTY

U-Line Corporation warrants each U-Line product to be free from defects in materials and workmanship
for a period of one year from the date of purchase; and warrants the sealed system (consisting of the com­pressor, the condenser, the evaporator, the hot gas bypass valve, the dryer and the connecting tubing) in
each U-Line product to be free from defects in materials and workmanship for a period of five years from
the date of purchase. During the initial one-year warranty period for all U-Line products U-Line shall: (1)
at U-Line’s 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 Product 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.U-LineService.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 23220, Milwaukee, Wisconsin 53223
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
U-Line’s 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-Line’s 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.

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.).

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

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.

U-Line will not cover part or labor claims for the replacement of a complete ice maker assembly. All ice
maker parts are available as replacement parts and are stocked in our inventory. Remember: we do not
pay customer education calls. 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, for warranty payment.

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/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/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/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, etc.), we will be able to process the
invoice for you in a timely manner.

ÉCHELON™ DOOR ADJUSTMENT

All Échelon™ model doors are aligned at the factory before shipment. Occasional re-adjustment may be
necessary, especially if an Overlay Panel is installed. The following procedure will correct for up to 1/4"
alignment.

T

o adjust door:

1. Compare the top edge of the door (opposite the hinges) to the top edge of the cabinet and note the
type (up or down) of adjustment needed.

2. Remove the top hinge pivot pin with a 7/64" hex wrench (see Figure 2) and lift door off bottom hinge
pin. Be careful not to lose door closer inserts (see Figure 5).

Note: The hinge plate on some Échelon™ models does not

have the holes slotted for adjustment. New hinge
plates are available from U-Line Customer Service.

3. With door upside-down, inspect the bottom hinge plate
mounting holes.

a. If your plate has slotted mounting holes, loosen

but do not remove the two hinge plate screws.

b. If your plate does not have slotted mounting

holes, remove the old plate and install the new
plate with the notch to the inside of the door
(see Figure 3).

The door should never be flush with the top of the cabinet. Even when level, the top edge of
the door will be 1/8" below the top of the cabinet (see Figure 1).

IMPORTANT

Figure 1

Figure 2

1/8"

DOOR001

UL310

4. If door edge opposite the hinges needs to move up, move plate toward outside of door. If door edge
needs to move down, move plate toward inside of door (see Figure 3). Repeat until top edge of door is
parallel with top of cabinet and tighten screws securely.

5. If you have an older model, you must slot the door frame to accommodate the door closer boss. Using
the bottom hinge plate pivot hole as a guide, slot the frame hole by using an 11/32" drill.

6. After adjustment is complete, remove the door closers from the bottom hinge,
clean thoroughly and apply petroleum jelly to the mating surfaces of the
closers (see Figure 5). Be sure that bosses on closers align with holes in
hinge and hinge plate. Mount door and install top hinge pivot pin.

GUIDE FOR SCREENING CALLS

U-line’s warranty does not cover customer education calls. It has been reported that as high as 50% of all
service calls performed are customer education calls.

The following guide has been developed to help screen calls on the most common customer education
issues. It can be used by persons scheduling service calls. Questions to ask before scheduling a service
call:

The unit is not cold enough!

• Are you familiar with the factory specifications for this unit? (Many factors can cause these figures to
vary: ambient temperature, application, amount of use, etc.)

Model Numbers Approximate Temperatures

2075WC, 2015WC 60° top rack /55° middle/ 45° bottom
2075R, 2015R 38°
2075RF 38° fresh food, 0° freezer
CO2075FF, U-CO29FF 38° fresh food

• Is the door sealing properly? If the door is not sealed properly, it allows heat into the unit. U-Line’s war­ranty is 90 days for door adjustments.

• Is the condenser clean? U-Line’s warranty does not cover cleaning the condenser.

• Is the unit behind closed doors? The unit must have free air flow to the front grille.

• Did you try turning the temperature control colder? Turning the control knob clockwise is colder. Be
sure to allow 24 hours between temperature control adjustments.

• For Wine Captain Units Only - Is the light on constantly to display the wine? If the light is on
constantly, this could cause the unit to run warmer.

The unit is frosting up!

• Are you familiar with the defrost technology of the unit?

Defrost Technology Model Numbers

Manual Defrost BI•2015
Cycle Defrost 2075R, 2015R, 2075WC, 2015WC

• Is the door sealing properly? U-Line's warranty is 90 days for door adjustments.

• Has the door been left open?

• Is the unit in an application of heavy usage? Heavy usage or high ambient temperatures will cause a
unit to frost up.

The light on my Wine Captain never shuts off!

• Did you turn the ON/OFF switch near the base of the unit? The ON/OFF switch is for the light
operation only. When the switch is in the OFF position, the light will turn on only when the door is
open. When the switch is in the ON position, the light will be on constantly to display the wine. To
shut the unit OFF, turn the temperature control all the way counterclockwise.

• 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 to 34 degrees.

The floor is very warm in front of my CLR2060 Model

• The unit is designed for a built-in application, so the warm air will discharge out the bottom of the unit
below the door. There is a safety feature built into the control board that will shut the unit down if the
warm air cannot be dissipated.

No ice, water pours into the trough and down into the drain - CLR2060
Model Only

When I turn the unit on, all I get is water fill - CLR2060 Model Only

• Check to be sure switch is in ice mode.

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

My ice does not come out in a perfect cube shape - CLR2060 Model Only

• The manner in which the ice is made causes a small hole or “dimple” to 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. A
service company will need to make this adjustment.

The cubes do not fall into bin as individual cubes - CLR2060 Model Only

• Normal - You can use the scoop to break apart.

Not enough ice is stored in the bin - CLR2060 Model Only

CO2075FF AND U-CO29FF ICE MAKER OPERATION

Note: The refrigeration system operates independently of the ice maker. This is a new design for U-Line.

All other U-Line ice makers use a double throw control system where the unit is either in a freeze
mode or harvest mode. In the CO2075FF and the U-CO29FF the refrigeration system will cycle on
and off depending on the temperature of the freezer. In most cases this means the refrigeration
system will be operating during the ice making and harvest modes. If the freezer control is set too
warm the refrigeration system may cycle off during ice making mode, slowing the ice production
rate. If this happens adjust the freezer control colder.

Ice Maker Operating Cycles

1. Freeze Cycle
A. Ice maker thermostat (located behind grille) open.
B. Freezer control closed and refrigeration system is operating.

2. Harvest Cycle-1
A. Ice maker thermostat closed.
B. Refrigeration system operating.
C. If bin arm is up the harvest will not initiate.
D. Power goes through the bin switch to the ice maker motor and mold heater.

3. Harvest Cycle-2
A. Ice maker ejector blades reach 2:00 position and cam depresses the hold switch.
B. Ejector blades stall on ice and ice maker motor pulsates until mold heater warms and ice releases.
C. Refrigeration system operating.

4. Water Fill Cycle
A. Ice maker blades reach approximately 10:00 position and cam depresses the water fill switch.
B. Power to the water valve. Ice maker mold fills.
C. Refrigeration system operating.

5. Eject Cycle
A. Ejector blades push ice into bucket and stop at 12:00 position.
B. Ice maker temperature control opens.
C. Refrigeration system still operating.
