Change compressor
Repairs to the cooling system may only
be carried out by trained professionals.
When changing the compressor, the
filter drier must also be replaced.
Is is important to cut out the filter drier,
as heating with solder flame will release
moisture inside the dry filter. This will
vaporize and drive moisture from filter
drier back into system.
The quantity and type of the refrigerant
used in your appliance is indicated on the
rating plate.
Do not make sharp bending angels on
the pipes.
The distance between the pipes must be
at least 12 millimetres.
