IV. Refrigeration Circuit and Component Service Information

WARNING

•This appliance should be diagnosed and repaired only by qualified service personnel to reduce the risk of death, electric shock, serious injury, or fire.

•Move the control switch to the "OFF" position, then unplug the appliance from the electrical outlet before servicing.

•CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after the icemaker is serviced. Make sure that none have fallen into the ice storage bin.

•Make sure all food zones in the icemaker and ice storage bin are clean after service.

A.Refrigeration Circuit Service Information

WARNING

•Repairs requiring the refrigeration circuit to be opened must be performed by properly trained and EPA-certified service personnel.

•Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of refrigerant to the system (if using an electronic leak detector), and then raise the pressure using nitrogen gas (140 PSIG). Do not use R‑134a as a mixture with pressurized air for leak testing.

NOTICE

•Always recover the refrigerant and store it in an approved container. Do not discharge the refrigerant into the atmosphere.

•Do not leave the system open for longer than 15 min. when replacing or servicing parts. The Polyol Ester (POE) oils used in R-134a applications can absorb moisture quickly. Therefore it is important to prevent moisture from entering the system when replacing or servicing parts.

•Always install a new drier every time the sealed refrigeration system is opened.

Do not replace the drier until after all other repair or replacement has been made. Install the new drier with the arrow on the drier in the direction of the refrigerant flow.

•When brazing, protect the drier by using a wet cloth to prevent the drier from overheating. Do not allow the drier to exceed 250°F (121°C).

1.Refrigerant Recovery

No refrigerant access valves are provided on this appliance. Using proper refrigerant practices, utilize a temporary tap-line valve on the high side to recover the refrigerant. Store the refrigerant in an approved container. Do not discharge the refrigerant into the atmosphere. After recovery is complete, replace the tap-line valve with a proper, permanent access valve.
