Receiver
The receiver collects the liquid 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 desiccant bag in the receiver.
Note:
- Replace the receiver 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
- Only remove sealing plugs shortly before installation.
- A desiccant bag in an unsealed receiver 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 receivers are installed directly on
the condenser and possess a dryer cartridge.
Note:
- Replace the dryer cartridge 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
- Only unpack dryer cartridge immediately prior to
installation.
- Dryer cartridge in unsealed packaging is saturated with
moisture after a short period of time and unusable.
