V. Removal and Replacement of Components

IMPORTANT

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

IMPORTANT

1.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.

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

3.Do not leave the system open for longer than 5 minutes when replacing or servicing parts.

1.Service for Refrigerant Lines

[a] Refrigerant Recovery

The icemaker unit is provided with two refrigerant access valves – one on the low-side and one on the high-side line. 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.

[b] Evacuation and Recharge [R-404A]

1)Attach charging hoses, a service manifold and a vacuum pump to the system. Be sure to connect charging hoses to both high and low -side access valves.

IMPORTANT

The vacuum level and vacuum pump may be the same as those for current refrigerants. However, the rubber hose and gauge manifold to be used for evacuation and refrigerant charge should be exclusively for POE oils.

2)Turn on the vacuum pump. Never allow the oil in the vacuum pump to flow backward.

3)Allow the vacuum pump to pull down to a 29.9" Hg vacuum. Evacuating period depends on pump capacity.

4)Close the low-side valve and high-side valve on the service manifold.
