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 two years after the applicable warranty period.

6.THIS LIMITED WARRANTY IS IN LIEU OF ANY AND ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY
IMPLIED WARRANTY OF MERCHANTABILITY OR IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, ALL OF
WHICH ARE DISCLAIMED. U-Line's sole liability and your exclusive remedy under this warranty is set forth in the paragraphs above. U­Line 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.

7.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.

U-Line Warranty

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 U-Line’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 [e-mail],
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

Warranty claims must be filed within 60 days after the
completion of the service call

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 30 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.

Thermistors

There are 2 thermistors used with the 3018 models.

• Zone Thermistor - Located on the right hand wall and is used to
maintain temperature.

• Evap Thermistor - Located on the back of the evaporator plate
and is used during defrost. Normal defrosting is based on a time
and temperature scale. Defrost ends if the evaporator thermistor
reaches stop point (42°) or maximum time, (90 minutes)
whichever comes first.

• Ambient Thermistor - Located in the base of the unit on the
condenser and is used to monitor ambient air temperatures.

Thermistor Calibration

While thermistors generally do not require calibration, over time
contact corrosion and or element wear may make calibration
necessary.

General Information

Viewing Temperature

Note: The display shows set point NOT the actual temperature.

The 3000 series is equipped with an advanced electronic display and
control. Thermistor readings can be obtained through both the
customer and service menu. The customer menu will display readings
with offsets adjustments taken into consideration. It is important to
note that the system will use adjusted readings when determining
cooling and defrost cycles. The service menu will display the actual
thermistor reading while disregarding offsets.

If a thermistor reports a temperature difference in excess

of 4°F, the thermistor should be replaced.

Calibration

To calibrate a thermistor one must first prepare an ice-bath of
crushed ice and water in a suitable container. Allow the ice bath
temperature to stabilize for at least 5 minutes before beginning.

1. Make certain the offset for the thermistor to be tested is set to 0.
See “Offsets” on page

2. Fully submerge the thermistor to be calibrated in the prepared ice
bath. It is important the thermistor is surrounded only by the ice
bath and is not touching any walls of the container.

3. View temperature through the customer menu, see “Customer
Menu” under “Viewing Temperature” on page 6.

4. The thermistor should read 32°F. If different, record difference. If
difference is greater then 4°, replace thermistor.

5. Adjust thermistor offset, see “Offsets” on page 12.

6. Repeat step 3 and confirm the new reading is 32°F.

General Information

USB Communication

The 3000 series uses an advanced USB logging feature for system
logging and diagnostics. The controller outputs 36 separate data
points per second to either a USB flash disk or transmits over USB
via TTY to a client PC. To prepare the unit for logging, first verify the
USB port is set to the proper configuration. See “USB Port” on page

14 for information on configuring the USB port.

Flash Mode:

Suitable for logging directly to a USB flash disk.

PC Link Mode:

Suitable for communicating directly with another PC via USB.

USB Communication (Flash)

The main control can host a wide range of flash disks up to a max
capacity of 8GB. After verifying the USB port is set to “Flash” simply
insert a flash disk in to the USB port located above the grille. The
flash disk activity light (located on the flash disk) will begin flashing
immediately as data is recorded to the drive. Data is recorded in one
second increments and is only limited by the capacity of the flash disk.

The system will create a file named “uline.csv” on the flash disk. In
the event the file already exists, new data will automatically be
appended to the end of the existing file. The file is output in a comma
delineated text format and may be viewed in a wide variety of simple
text readers or spreadsheet programs.

For information on identifying each data point, see the
“Communication Data” table on page 18.

USB Communication (PC Link)

Data can be transmitted directly to a client PC via a serial
connection. Verify the USB port is set to “PC Link”. Use a Type A to
Type A male to male USB cable to connect the system to a
Windows® compatible PC. It is necessary to install communication
drivers to the client PC. Drivers may be downloaded at
www.u-lineservice.com. Establish a connection using a Telnet / TTY
terminal application. U-Line recommends PuTTY. PuTTY is available
for download at www.u-lineservice.com. Once the connection is
established, the controller will output a series of 36 data points in 1
second increments. For information on identifying each data point,
see the “Communication Data” table on page

Convection Cooling

All 3000 series units are equipped with an advanced convection
cooling system. Convection cooling stabilizes cabinet temperature,
cools product faster and increases energy efficiency.

Evaporator Fan

The evaporator fan is responsible for circulating warm are from the
refrigeration zone, pass the evaporator and back into the refrigerated
zone,

The evaporator fan is factory set to have a 1 minute delay at the
beginning of a cooling cycle. This delay gives the evaporator time to
cool properly before warm air is passed over it. The fan will continue
to run for an additional 2 minutes at the end of a cooling cycle. Fan
delay times can be modified through the service menu. See “Fan
Delay” on page

Evaporator fan operation is also determined by door switch state. If
the door switch circuit opens the fan will stop. When the door
switch circuit is closed the fan will either continue running with the
cooling cycle, or if not currently cooling the fan will run for 1 minute
to circulate air and clear any condensation that may have appeared on
glass doors and shelves.

Note: If the unit is set to sabbath mode the evaporator fan will no
longer respond to the state of the door switch.

In order to operate efficiently the evaporator fan blade and vents
should be unobstructed and free of any dust build up.

Evaporator Fan Replacement

14.

5. Remove insulating foam from refrigerant line pass-through hole.

6. Remove internal shelving, bins, or wine racks.

7. Remove shelf clips, rack, or bin mounting rails.

8. Remove thermistor cover.

audible tone if the door/drawer has been left open for longer

than 5 minutes.

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

ing the condenser.

• Is the unit behind closed doors or the grille restricted? The front

grille must be free of obstruction.

• Is the unit in an application of heavy usage? Heavy usage or high

ambient temperatures will cause a unit to frost up.

• Did you try adjusting the temperature to a colder level? Adjust

to a colder level. Be sure to allow 24 hours between temperature

control adjustments.

Temperature is too cold. • Check actual temperature versus set-point.

• Did you try adjusting the temperature to a warmer level? Adjust

to a warmer level and allow 24 hours between temperature con

trol adjustments.

Product is freezing. • What is the temperature set at?

• Do not allow products to lean against the evaporator at the back

wall.

The unit is frosting up. • Are you familiar with the defrost technology of the unit?

Compressor Information

Cooling process

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

Thermistors

Thermistors are used for various temperature readings. Thermistor
provide reliable temperature readings using a resistance which varies
based on surrounding temperatures. If a faulty thermistor is
suspected it may be tested using an accurate ohmmeter. In an ice bath
(32°F) resistance should measure 16.1 kilohms,

5K Ohms - 70°F ambient.

16.1K Ohms - 32°F ambient

Thermistor Failure

Zone Thermistor

If the zone thermistor fails the unit will continue to operate on a
preset time interval of 10 minutes on and 30 minutes off. The unit
will otherwise operate normally. The error will be displayed on
the main display and “Self Test” and logged in “All Errors”.

Evaporator Thermistor

If the evaporator thermistor fails the unit will rely on a preset
defrost timer during defrost cycles. The unit will otherwise
operate normally. Evaporator thermistor errors are hidden from
the display and recorded in “All Errors” and displayed in “Self
Te s t ” m o d e s .

Ambient Thermistor

The ambient thermistor is mainly used for diagnostics. If the
thermistor fails the unit will operate normally.

Reed Switch

A reed switch is used to monitor door state. The switch side is
mounted under the cabinet and the magnet is mounted to the cable
arm. When the door is closed magnetic force pulls the reed to its
contact and closes the circuit which turns the light and display off.
When the door is open the reed pulls away from the contact and
opens the circuit. If the door or drawers are left open for longer than
5 minutes, the switch will trigger an error code and set an audible

warning

Compressors

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 wrist strap that is grounded to an electrical
ground or grounded water pipe.

• Handle circuit boards carefully and avoid touching

components

To measure the start winding resistance, measure across the C and S
pins.

To measure the run winding resistance, measure across the C and R
pins.

Also check S to R and you should get the sum of the run and start
windings.

To ensure the windings are not shorted, check the S and R to ground.

Entertain with U-Line Elegance

BUILDING ON THREE GENERATIONS OF INNOVATION

For nearly five decades and three generations, U-Line continues to be the leader in innovation, quality and value in the
premium built-in undercounter ice making, refrigeration and wine preservation market. U-Line has captivated those
with an appreciation for the finer things with exceptional functionality, style, inspired innovation and attention to even
the smallest details. We are known and respected for our unwavering dedication to product design, quality and selec­tion.

In 1962, Henry Uihlein founded U-Line Corporation as an outgrowth of Ben-Hur Freezer Company and was the first
to develop and patent an automatic stand-alone undercounter residential ice maker. His foresight and determination
to develop new ideas and to succeed when there were no clear guidelines or solutions are evident today. The newest
Uihlein generation continues to build upon the family’s innovative legacy at the Milwaukee, Wisconsin based business
by providing continuity and vision from which new designs and technology continue to be born.
