Removal and Replacement of Components | Hoshizaki DCM-500BWH-OS

V. Removal and Replacement of Components

IMPORTANT

1.Ensure all components, fasteners, and thumbscrews are securely in place after the equipment is serviced.

2.The Polyol Ester (POE) oils used in R-404A units can absorb moisture quickly. Therefore it is important to prevent moisture from entering the system when replacing or servicing parts.

3.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.

4.Do not leave the system open for longer than 15 minutes when replacing or servicing parts.

A.Service for Refrigerant Lines

WARNING

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.

1. Refrigerant Recovery

The icemaker is provided with refrigerant access valves. Using proper refrigerant practices, recover the refrigerant from the access valves and store it in an approved container. Do not discharge the refrigerant into the atmosphere.

2. Brazing

WARNING

1.R-404A itself is not flammable at atmospheric pressure and temperatures up to 176°F (80°C).

2.R-404A itself is not explosive or poisonous. However, when exposed to high temperatures (open flames), R-404A can be decomposed to form hydrofluoric acid and carbonyl fluoride both of which are hazardous.

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

4.Do not use silver alloy or copper alloy containing arsenic.

5.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.
