12.1 Servicing the heat pump circuit

12.1.1 Replacing the compressor

Disconnect the appliance from the power supply.
Use the special needle valve (1) to evacuate the gas.
Dispose of the R134a liquid coolant in the appropriate manner.
Loosen the compressor anchor elements to facilitate access.
Use a pipe-cutter to cut the intake pipe (2) and the delivery pipe (3).
The compressor can now be replaced.
Connect the intake and delivery pipes to the circuit using LOCKRING
couplings.
A Schrader valve (4) may be fitted to the intake pipe for filling and draining
the circuit of the heat pump.
Alternatively, it is possible to connect a separate filling coupling with a valve
(6) to the existing fill pipe (5).

12.1.2 Evacuation

The duration of the evacuation cycle must be at least 15 minutes. Evacuation
should be performed on the intake side only.
This operation removes most of the extraneous gas and humidity from the
cooling circuit.
The evacuation of the circuit must take place with the compressor switched
off. During evacuation the compressor should be shaken at least once in
order to release as much extraneous gas as possible from within the oil.
12.1.3

Filling

The liquid coolant may be topped up directly from
the canister using a special balance.
R134a liquid coolant is sold in disposable
canisters.
When filling with coolant, the compressors must be
switched off and the service engineer must wear
the appropriate protective clothing.
