Special Tools
A desiccant insert that is in a correctly functioning, sealed heating and air conditioning system does not have to be changed at regular service-inspection intervals.
However, the dryer flask or desiccant insert must absolutely be replaced in the event of:
- contamination of the refrigerant with swarf (e.g. when the compressor is clamped).
- With depressurized and/or completely drained refrigerant circuit.
- With a refrigerant circuit, which was closed using special tool 32 1 270 but remains open for more than 24 hours.
