USER GUIDE
Cleaning
Stainless Models Stainless door panels and handles can discolor when exposed to chlorine gas, pool chemicals, saltwater or cleaners with bleach.
Keep your stainless unit looking new by cleaning with a good quality all-in- one stainless steel cleaner and polish monthly. For best results use Claire® Stainless Steel Polish and Cleaner. Comparable products are acceptable. Frequent cleaning will remove surface contamination that could lead to rust. Some installations may require cleaning weekly.
Do not clean with steel wool pads.
Do not use stainless steel cleaners or polishes on any glass surfaces.
Clean any glass surfaces with a non-chlorine glass cleaner.
Do not use cleaners not specifically intended for stainless steel on stainless steel surfaces (this includes glass, tile and counter cleaners).
If any surface discoloring or rusting appears, clean it quickly with Bon-Ami® or Barkeepers Friend Cleanser® and a nonabrasive cloth. Always clean with the grain. Always finish with Claire® Stainless Steel Polish and Cleaner or comparable product to prevent further problems.
Using abrasive pads such as ScotchbriteTM will cause the graining in the stainless steel to become blurred.
Rust not cleaned up promptly can penetrate the surface of the stainless steel and complete removal of the rust may not be possible.
Integrated Models

To clean integrated panels, use household cleaner per the cabinet manufacturer’s recommendation.
INTERIOR CLEANING Disconnect power to the unit.
Clean the interior and all removed components using a mild nonabrasive detergent and warm water solution applied with a soft sponge or non-abrasive cloth.
Rinse the interior using a soft sponge and clean water.
Do not use any solvent-based or abrasive cleaners. These types of cleaners may transfer taste to the interior products and damage or discolor the lining.
DEFROSTING Under normal conditions this unit does not require manual defrosting. Minor frost on the rear wall or visible through the evaporator plate vents is normal and will melt during each off cycle.
If there is excessive build-up of 1/4″ (6 mm) or more, manually defrost the unit.
Ensure the door is closing and sealing properly.
High ambient temperature and excessive humidity can also produce frost.
! CAUTION
DO NOT use an ice pick or other sharp instrument to help speed up defrosting. These instruments can puncture the inner lining or damage the cooling unit. DO NOT use any type of heater to defrost. Using a heater to speed up defrosting can cause personal injury and damage to the inner lining.

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.
33

USER GUIDE

! 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.)
34

USER GUIDE

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

35

USER GUIDE

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. (run compressor an extra two minutes to clear the charging hoses).
Seal the Schrader Type access port, a proper cap and seal must be used to close the system.

SUMMARY Safely handling R-600a requires proper procedures and training.
R-600a approved service tools must be used.
R-600a labeling must not be removed or altered.

USER GUIDE

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.
Both thermistors in the unit are identical. If a thermistor is suspected of being defective, the resistance can be verified. Place the thermistor in an ice water bath, the resistance should read 16.1k Ohms +/-5% on your meter.
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.
Thermistor error information can be found in the Control Operations – Service section.
This unit has two thermistors.
Thermistor one (Zone): Located along the right hand side wall. It is used to maintain the operating temperature within that zone.
Thermistor two (Evaporator): Located on the evaporator. It is used for defrost.
THERMISTOR FAILURE
Zone Thermistor If the zone thermistor in the unit fails, the unit will continue to cool in a backup mode (Self Preservation Mode) to preserve the integrity of the contents. The unit will otherwise operate normally.

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. Refer to defrost section.

Defrost
This unit defrosts, by default, every 12 hours of compressor runtime for 45 minutes. If you have verified that the unit does not have an ambient air leak, refer to the Control Operation – Service section and adjust unit to defrost every 9 hours for 60 minutes. Also, adjust the #2 thermistor to -4 instead of 0.

CONVECTION COOLING This unit is 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.
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.
Evaporator Fan Replacement Should the evaporator fan need to be replaced follow the steps below.
1. Remove any product from the unit.
2. Remove unit from cabinetry to access rear.
3. Disconnect power to the unit.
4. Remove back panel from unit.
5. Disconnect fan electrical connection at rear of unit.

6. Remove insulating foam from refrigerant line passthrough hole as needed to gain clearance for fan plug.
7. Remove internal shelving. 8. Remove 8 evaporator cover screws.
9. Grasp evaporator cover, pull forward and up as bottom of cover is installed behind the front edge of the drain trough.
10. While pulling the evaporator cover clear of the unit, it may be necessary to use your free hand to manipulate the fan plug end through the pass-through hole.
