PRODUCT LIABILITY POLICY

In the event that a U-Line unit is involved in an alleged property damage claim, it must remain unaltered and unrepaired for evaluation. No service or repairs should be performed on any unit suspected to be involved in property damage. If a unit has been altered or repaired in the field prior to U-Line's evaluation, any claim for damage may be declined.

When a product evaluation is needed, it is the consumer's responsibility to assure that the unit is returned for evaluation. Please call U-Line immediately at 1-800-779-2547 for assistance.

Field service technicians are authorized to make an initial assessment. If in the servicer's judgment the property damage is the result of a product defect, the product must be removed and returned to U-Line in an unaltered condition. The dealer is 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 Return Authorization (RA) and product exchange process.

If in the servicer's judgment, the property damage is the result of installation (water connection/drain, etc.), the consumer must be notified and the correction would be made by the servicer or installer without removing the product. Any claim for these damages must be directed to the original installer.

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

To complete the damage claim process for the consumer, please obtain the following information. This information can be emailed to U-Line at [e-mail], faxed to 1-414-354-5696 or mailed 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 Return Authorization (RA) number and consumer name when providing this information.

If a unit is returned to U-Line for evaluation, it will take approximately ten business days. No field service company is authorized to perform this evaluation. Once a Return Authorization (RA) Number is issued and the unit has been boxed in a U-Line carton, please contact U-Line to make arrangements for shipping. U-Line will keep the appropriate parties informed during the evaluation process.

If the evaluation finds the U-Line 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 for disposition.

If the evaluation finds the U-Line 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.

Thermistors

There are 3 thermistors used with the 3018/24 models.

• Zone Thermistor - Located on the right hand wall and is used to maintain temperature.
• Evaporator Thermistor - Located on the back of the evaporator plate 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.

I. Initiate the customer menu by holding Select 📷 for 5 seconds.
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.

I. Initiate the service menu by holding both up and Zone Toggle for 5 seconds.
2. Use Up or Down to scroll to "Actual Temperatures".
3. Press select .
Use Up or Down to scroll through available information.

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 16. 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 Customer Menu. See "Viewing Temperature".
4. Submerge the thermistor in the ice water. The temperature read out through the menu should be 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 Customer Menu, the temperature readout should now be 32^ . 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 water an offset 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 -10 through 10.

Note: If a mistake is made in the calibration process a "Factory Default" will restore offsets to their factory pre-set values. See page 17.

Air Flow

NOTICE

The unit requires proper air flow to perform at its highest efficiency. Do not block the front grille, internal fans or vents at any time, or the unit will not perform as expected. Do not install the unit behind a door.

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 air from the refrigeration zone, past 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 17.

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 buildup.

Troubleshooting

Main Control

The main control board is very robust and is rarely the cause of system issues. It is important to fully diagnose the board for any suspected failures before attempting to remove the board for replacement or service. Follow the guidelines below to fully test and diagnose the main control.

Power Fault

If the unit does not (or seems to not) power on, follow the flow chart below to help diagnose the issue. Before beginning it is important to first verify the unit is not simply set to sabbath mode.

Testing The Main Control

If the main control is suspected of being faulty, the following procedure should be performed to verify main control for functionality.

Relay & DC Outputs

One of the primary functions of the main control is to operate the multiple relay and DC outputs during each cycle. Verify proper operation of these relays using the following procedure.

I. Enter "Relay Toggle" through the service menu.

NOTICE

Frequently toggling the compressor relay could force the compressor into overload. The compressor will automatically deactivate during an overload and will remain deactivated until the overload switch cools. This could take some time. It is important to allow the compressor at least 5 minutes off time between relay cycles.

1. Toggle the relay. Its related component should activate / deactivate with the switching of the relay. If it does not, see "Component Testing" on page 2.

Inputs

The main control monitors a number of thermistor inputs and switch states during operation. It would be unlikely that an error in reading an input would be at the board level. Always attempt to replace the faulty switch or thermistor input with a known working sample to verify proper board operation.

Other Suspected Main Control Faults

If other components have been ruled out as being faulty but the unit continues to have operating issues, it is most likely due to a configuration error. Configuration errors can be cleared by restoring the unit to its factory default setting. Factory defaults may be restored through the service menu. See page 17.

CAUTION

Precautions must be taken while working with live electrical equipment. Be sure to follow proper safety procedures while performing tests on live systems.

Component Testing

NOTICE

Frequently toggling the compressor relay could force the compressor into overload. The compressor will automatically deactivate during an overload and will remain deactivated until the overload switch cools, regardless of relay and voltage state.

NOTICE

If the compressor is suspected of being faulty it is important to verify all copper tubing, dryers, capillary lines, evaporators and condensers are free from kinks, excessive bends or blockages. A restriction in any of these components would force the compressor to overload, making it appear as if it is faulty.

If a component is suspected as being faulty, follow the troubleshooting steps below to help isolate the cause.

I. Initiate Self Test Mode, address any current errors before beginning component testing.
2. Activate the component's relay or DC output through "Relay Toggle" under the service menu.
3. Test for voltage at the component.

Voltage Present

If voltage is present and the component does not function, suspect a faulty component. If the component being tested is the compressor, make certain it is not overloaded by disconnecting power to the unit for at least 15 minutes and re-testing.

No Voltage Present
Connector & Pin ID

If no voltage is present check for voltage at the relay / DC output. Reference the diagram for component relay / DC output pins. If voltage is present, suspect a faulty component cable. If voltage is not present at the relay / DC output, cycle the power to the unit and re-test. If voltage is still not present, suspect the main control of being faulty.

Component Testing Example

Below is an example of how to properly test a component for functionality. An evaporator fan is used.

Condition

Customer complains of the unit not cooling properly. The main screen of the display lists an error "Temp Hi 12H+". The compressor seems to be functioning properly, however the evaporator fan does not activate after a door cycle.

In the above case it would be wise to test the evaporator fan for functionality.

Testing

1. Check "Self Test" for any additional errors that may be current.
2. Visually examine the fan through the fan cover. Note any ice buildup. In this case no ice buildup was noticed. The fan appeared as if it could spin freely.
3. Enter "Relay Toggle" and manually activate FANI.
4. Check for fan operation. In this case the fan does not operate.
5. Remove the upper and lower back panel from the refrigeration unit.
6. Ensuring the DC output is still active, use a meter to check voltage at the fan power connection point. In this instance no voltage is present.
7. Ensuring the DC output is still active and referencing the Connector & Pin ID chart, a voltage test is performed across pins 1 and 6 of the header labeled J4. In this case a stable 12 volts DC was noted.

J4 Voltage Checked At These Pins

1. Confirming that the board is sending voltage, the cabling between the board and fan is inspected for damage. In this case some damage is noted.
2. The fan cable harness is replaced, and the fan DC output is tested again. It is noted the fan now spins freely.
3. The unit is then monitored for proper operation and any further faults.

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 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 through the discharge line and into the condenser. The cycle continues.

DANGER

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.

Thermistors

Thermistors are used for various temperature readings. Thermistors 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 water (32°F) resistance should measure 16.1 kilohms,

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, "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 Test" modes.

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 is left open for longer than 5 minutes, the switch will trigger an error code and set an audible warning.
