INTERNATIONAL PRODUCT LIABILITY POLICY (as of 11/4/2011)

Field service engineers are authorized to make an initial assessment. If in the engineer’s judgment the damage is the result of a product defect, the product would be removed and returned to the importer in an unaltered condition. The importer would then be authorized to permanently replace the end-user’s product at no cost to the end-user. The importer will notify U-Line and initiate a discussion regarding disposition along with holding the product unaltered for evaluation.

If in the engineer’s judgment, the damage is the result of installation, the end-user would be so notified and the correction would be made by the engineer or installer without requiring removal of the product. Any claim for damages should be directed to the original installer of the product.

Any U-Line product involved in an alleged property damage claim must remain unaltered and unrepaired, for evaluation. No service

or repairs should be performed on any product suspected to be involved in property damage. If a product has been altered or repaired in the field prior to the evaluation, any claim for damage may be declined. The product will be held (unaltered) at the importer for disposition until notified by U-Line.

To complete the damage claim process for the end-user, the importer must obtain the following and forward to U-Line at the email intl@u-line.com:

1. Pictures of the product, installation and any alleged property damage.

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

3. To expedite the claim process, two damage repair estimates will be needed.

4. Reference the Return Authorization (RA) number and end-user name when providing this information.

If a product is returned to the importer, the importer will work with U-Line to facilitate the evaluation. U-Line reserves the right to evaluate the product and will provide written (via email) approval for any person performing this evaluation. No field service engineer is authorized to perform this evaluation without approval from U-Line. When a Return Authorization Number is issued, and the product has been boxed in a U-Line carton, importer should be contacted and then will make arrangements for shipping, or designate a truck line to have the product shipped freight collect to the importer.

If the evaluation finds the product to be defective, the damage claim will be reviewed by the U-Line Customer Assurance Department.

If the evaluation finds the product not to be defective, all claims for damage will be declined.

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

Thermistor Info

There are 5 thermistors used with the 3090 models.

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

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

• Left Evaporator Thermistor - Located on the back of the evaporator plate in the left zone and is used during defrost.

• Right Evaporator Thermistor - Located on the back of the evaporator plate in the right zone and is used during defrost.

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

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 while using offset calculations. It is important to note that the system will use these adjusted readings when determining cooling and defrost cycles. The service menu will display the actual thermistor reading while disregarding offsets.

Customer Menu

To view the adjusted temperature of each available thermistor, follow the steps below.

1. Initiate the customer menu by holding Select

2. Use Down to scroll to “Actual Temperatures”.

3. Press select .

4. Use Up or Down to scroll through available information.

Service Menu

To view the actual temperature without having the offsets taken into consideration, follow the steps below.

Thermistor Calibration

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

Calibration

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

NOTICE

Offsets are preset at the factory to efficiently maintain product temperature. If modifying offset, existing values must be taken into consideration.

NOTICE

Customer Care must be notified before any changes are made to factory set offsets. Failure to notify Customer Care will void the warranty.

1. Enter the service menu and record existing offset values for each thermistor to be calibrated. See page 12. Some models have a factory offset setting of 0.

2. Change offset of each thermistor to be calibrated to 0.

3. Enter “Actual Temps” through the “Viewing Temperature”.

4. Submerge the thermistor in the ice out through the menu should be 0°C (32°F). If different, record difference.

5. Enter “Offsets” through the service menu and set the value recorded in step 4 to the thermistor to be calibrated.

6. Enter “Actual Temps” through the temperature readout should now be 0°C (32°F). If the readout is still incorrect reset the offset to 0 and perform steps 4 & 5 again.

7. Enter the “Offsets” menu and add the value recorded in step 1 to the new offset setting. For example, if after the ice of 1 was needed and the existing offset value recorded in step 1 was -2 the new offset value would be -1. If the calculated value is outside the maximum range capable in the offset menu the thermistor must be replaced. The offset menu has a maximum range of -5°C through 5°C.
