Keep a dry powder type fire extinguisher in the work area. Technician must observe all federal, state and local laws regarding refrigerants. R-600A Specifications R-600a is heavier than air, do not allow any leakage/migration to low areas such as basements and stairs. Never use a torch on a fully charged refrigeration system. Never substitute U-Line OEM replacement parts or methods of construction. R-600a must be stored and transported in approved containers. 35 USER GUIDE u-line.com ! WARNING Only skilled and well trained service technicians permitted to service R-600a equipped products. All tools and equipment must be approved for use with R-600a refrigerant. Local, state and federal laws, standards must be observed along with proper certification and licensing. Ventilation is required during servicing. No conversions to R-600a from any other refrigerants. OEM R-600a equipped unit only. Service area must be free of ignition sources. No smoking is allowed in the service area. All replacement electrical components must be OEM and installed properly (sealed and covered). If the evaporator is cold prior to service, it must be thawed prior to service. When using a vacuum pump, start pump before opening refrigeration system. Vacuum pump and recovery equipment should be at least 10 feet from the work area. It is recommended that a simple LPG gas detector is on site during service. Ensure that all R-600a is removed from the system prior to brazing any part of the sealed system. Only a clean, dry leak free system should be charged with R-600a. R-600A Specifications R-600A SPECIFICATIONS/LABELING R-600a equipped products are labeled (both the unit and the compressor). R-600a is colorless and odorless. R-600a is considered non-toxic, but is flammable when mixed with air. Do not remove or alter any R-600a labeling on the product. Use only a refrigerant grade R-600a from a properly labeled container. RECOVERING/RECLAIMING R-600A (R-600a has been exempted from recovery/reclaiming requirements by the US EPA) Recovery/Reclaiming equipment must be approved for use with R-600a. Ensure the evaporator is at room temperature prior to recovery/reclaiming R-600a. Use a common piercing pliers or piercing valve to remove R-600a from the compressor process tube. (Note: Piercing devices must not be left on the system and must be replaced with a Schrader type valve.) 36 USER GUIDE u-line.com Evacuate/reclaim via the piecing pliers to ensure the system is empty of R-600a before any system work is performed. The recovery cylinder must be evacuated (no air inside) prior to accepting R-600a. The recovery cylinder must not be filled more than 45% safe fill level and refrigerants must not be mixed. The recovery cylinder must be clearly marked with R600a and Flammable Warning labels. Ensure proper ventilation during recovery/reclaiming of R600a. Start vacuum pump/recovery pump prior to piercing the compressor process tube. Follow recovery/reclaim OEM instructions for the specific equipment used. SYSTEM REPAIR Ensure no residual R-600a refrigerant is left within the system prior to repair (simple venting is not sufficient). Evacuate and charge with dry nitrogen for leak checks. Repair leaks or replace system parts as required. When re-brazing, the system must be purged with dry nitrogen and at least one access point open to the atmosphere. When re-brazing, proper ventilation is required along with constant monitoring for the presence of R600a refrigerant. The filter dryer must be replaced any time the sealed system is serviced. No system should be open to the atmosphere for longer than 15 minutes to avoid moisture migration into the system components. LEAK DETECTION After removal of the R-600a, the unit can be charged with dry nitrogen or helium. Electronic leak detection or soap solution can be used to check for nitrogen/helium leaks. Never use a halide torch or lighted match to check the system for leaks at any time. The high side of the refrigeration system (compressor discharge to outlet of drier) must be leak tested with the compressor running. R-600A Specifications 37 USER GUIDE u-line.com The low side of the refrigeration system (evaporator, compressor and suction line) must be leak tested with the compressor off (equalized pressure). RECHARGING No air is ever to be allowed inside the refrigeration system (R-600a refrigerant or dry nitrogen only). Never use a torch on a fully charged refrigeration system. Install a Schrader Type access port on the compressor process stub. Proper ventilation during service is required. Never apply a torch to a charged R-600a refrigeration system. Use OEM replacement service parts and do not alter the construction of the unit. Evacuate the system to 100 microns prior to charging. Weigh in the R-600a charge using a refrigerant scale.

Troubleshooting Extended 42 USER GUIDE 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. 1. 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. 2. Toggle the relay. Its related component should activate / deactivate with the switching of the relay. If it does not, test component. 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. Some configuration errors can be cleared by restoring the unit to its factory default setting. Factory defaults may be restored through the service menu. If that does not work, check that the board is programmed to the correct model in the service menu. ! CAUTION Precautions must be taken while working with live electrical equipment. Be sure to follow proper safety procedures while performing tests on live systems. u-line.com PLUNGER SWITCH A plunger switch is used to monitor door state.

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. Thermistor connections must be kept clean. A thermistor connection that has become corroded can cause resistance values from the thermistor to change as they pass through a dirty connection to the board. It is for that reason that we apply dielectric grease to all of our thermistor connections. Dielectric grease will help to keep thermistor connections clean and dry. If you change a thermistor in the unit, please re-apply dielectric grease to the connection. If you encounter a dirty thermistor connection, you should replace the thermistor and the thermistor harness. This unit has one thermistor located along the right hand sidewall of the ice bin. It is used to maintain the ice level in the bin. u-line.com Thermistor Resistance Data Temp (F) -40 -31 -22 -13 -4 5 14 23 32 41 50 59 68 77 86 95 104 113 122 131 140 149 158 167 176 * (+/- 5%) Temp (C) -40 -35 -30 -25 -20 -15 -10 -5 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 Nominal Resistance (OHMS)* 169157 121795 88766 65333 48614 36503 27681 2116 16330 12696 9951 7855 6246 5000 4029 3266 2665 2186 1803 1495 1247 1044 879 743 631 Thermistor 49 U-Line Corporation (U-Line) Limited Warranty One Year Limited Warranty For one year from the date of original purchase, this warranty covers all parts and labor to repair or replace any part of the product that proves to be defective in materials or workmanship.
