V. Replacement of Components

WARNING

•This icemaker 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 and turn off the power supply before servicing. Lockout/Tagout to prevent the power from being turned back on inadvertently.

•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 dispenser unit/storage bin.

•Make sure all food zones in the icemaker and dispenser unit/storage bin are clean after service. For cleaning procedures, see "VI. Cleaning and Maintenance."

A.Service for Refrigerant Lines

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‑404A 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 minutes when replacing or servicing parts. The Polyol Ester (POE) oils used in R-404A 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

The condensing unit is provided with refrigerant shutoff valves and the icemaker is provided with refrigerant service valves. Using proper refrigerant practices, recover the refrigerant. Recovery via the condensing unit's refrigerant shutoff valves is recommended. Store the refrigerant in an approved container. Do not discharge the refrigerant into the atmosphere.
