Fluid Reservoir

The receiver collects the fluid drops and then directs them in an uninterrupted stream to the expansion valve. Moisture which has entered the refrigerant circuit during repairs will be collected by the dryer bag in the reservoir.

NOTE:

Replace the reservoir if refrigerant circuit has been open for a long time (beyond the normal repair time) and moisture has penetrated inside, or if required due to a specific complaint. Refer to COMPONENT REPLACEMENT .

Only remove sealing plugs shortly before installation.

A dryer bag in an unsealed reservoir is saturated with moisture after a short period of time and unusable.

When installing, note arrow for direction of flow if necessary.

The new generation of reservoirs are installed directly on the condenser and contain a dryer cartridge.

Remove dryer cartridge from packaging shortly before installation.

The dryer cartridge becomes saturated with moisture and unusable after a short time in an unsealed package.
