Removal of Compressor
Removal Procedure
21
7
Heat up the brazed part
of the suction side and
disconnect it.
Cautions for restoration
1. Restore the piping by non-
oxidation brazing.
2. It is required to prevent the
carbonization of the oil inside
the four way valve and the
deterioration of the gaskets
affected by heat. (Keep
below 120°C.) For the sake
of this, wrap the four way
valve with wet cloth and
provide water so that the
cloth does not dry.
In case of difficulty with gas
brazing machine
1. Disconnect the brazed part
where is easy to disconnect
and restore.
2. Cut pipes on the main unit
with a tube cutter in order to
make it easy to disconnect.
Note:
Never use a metal saw to cut
pipes because the sawdust
may enter the circuit.
When withdrawing the pipes,
be careful not to pinch them
firmly with pliers. The pipes
may get deformed.
Provide a protective sheet or
a steel plate so that the
brazing flame cannot
influence peripheries.
Be careful so as not to burn
the compressor terminals,
the name plate, the heat
exchanger fin.
