ICE MAKER OPERATION When the ice bucket is full, the ice making mechanism will shut off. However, the refrigeration system will continue to cool and maintain the ice supply.
NOTICE Do not place cans or bottles in the ice compartment because they will freeze.
OFF
ON
To turn off ice production: Raise the bin arm into an upright and locked position. The unit will preserve temperature for ice storage.

! CAUTION
NEVER use an ice pick, knife or other sharp instrument to separate cubes. Shake the ice bucket instead.
During periods of limited use or high ambient temperatures, it is common for cubes to fuse together. Gently shake the bucket to break apart cubes. If not using the ice maker regularly, empty the ice bucket periodically to ensure fresh cubes.
It is normal for cubes to appear cloudy. The cause is air trapped in the water because of fast freezing. It is not caused by the health, taste or chemical make up of the water. It is the same air that is in every glass of water you drink.
Remove the ice bucket for emptying and cleaning. To remove the ice bucket, raise the bin arm and remove the bucket from the ice compartment. Use the ice bucket for ice storage only.

NOTICE If not intending to use the ice maker, turn the water supply valve off. It is also important to raise the bin arm of the ice maker (see above). Failure to raise the bin arm may result in damage to the water valve.
Certain sounds are normal during the unit’s operation. You may hear the compressor or fan motor, the water valve, or ice dropping into the ice bucket.

R-600A Specifications
For R-600a refrigerant service tips and more videos, go to: www.u-line.com/videos.
! WARNING
Flammability warnings for a pure-iso-butane refrigerant.

Gloves and Eye Protection must be used.
R-600a is considered non-toxic, but is flammable when mixed with air. 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.
30

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.)
31

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

32

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
Defrost
This unit requires manual defrost, periodically.
Inspect the interior walls for frost build up every 3 – 4 weeks. Defrost your unit when 1/4″ of frost builds up on the interior walls. Frost will build up faster in humid environments and when the door is opened frequently.
To defrost, remove ice bucket, turn off unit, leave door open, and allow frost/ice to melt naturally. Do not use tools to chip or scrape the frost as it may damage your unit. Use a towel to absorb melting frost/ice. Before turning the unit back on, make sure all the frost is gone and the unit is dry.
