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 1-800-779-2547 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 onlineservice@U-Line.com, fax
to 1-414-354-5696 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 u-lineservice.com. Warranty rate mustbe
agreed upon before submittal.
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.
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.
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, U.S.A., or fax it to
1-414-354-5696. Claims can also be filed on-line at u-lineservice.com.

General Information
Checking Product Temperature
To check the actual product temperature in the unit.
1. Partially fill a plastic (nonbreakable) bottle with water.
2. Insert an accurate thermometer.
3. Tighten the bottle cap securely.
4. Place the bottle in the desired area for 24 hours.
Normal Operating Sounds
All models incorporate rigid foam insulated cabinets to provide high
thermal efficiency and maximum sound reduction for its internal
working components. Despite this technology, your model may make
sounds that are unfamiliar.
Normal operating sounds may be more noticeable because of the
’s environment. Hard surfaces such as cabinets, wood, vinyl or
unit
tiled floors and paneled walls have a tendency to reflect normal
appliance operating noises.
Listed below are common refrigeration components with brief
description of the normal operating sounds they make. NOTE: Your
product may not contain all the components listed.
• Compressor: The compressor makes a hum or pulsing sound that
ma
y be heard when it operates.
• Evaporator: Refrigerant flowing through an evaporator may sound
lik
e boiling liquid.
• Condenser Fan: Air moving through a condenser may be heard.
• Automatic Defrost Drain Pan: Water may be heard dripping or
running into the drain pan when the unit is in the defrost cycle.
5. Avoid opening the unit during the testing period.
6. After 24 hours, check the temperature of the water. If required,
adjust the temperature control in a small increment (See
ADJUSTING THE SET-POINT).
Causes which affect the internal temperatures of the
cabinet include:
• Temperature setting.
• Ambient temperature where installed.
• Installation in direct sunlight or near a heat source.
• The number of door openings and the time the door is open.
• The time the internal light is illuminated. (This mainly affects
pr
oduct on the top rack or shelf.)
• The front grille or condenser are obstructed.
