Si11-990 Removal of Sound Blankets / Compressor
Removal Procedure 15
3. Removal of the sound
blankets
1Untie and remove the
sound blankets.
4. Removal of the
compressor
Reassembling precautions
Use non-oxidizing brazing
method. If nitrogen gas is
not available, braze the
parts speedily.
In pulling the pipes, be
careful not to over-tighten
them with pliers. The pipes
may get deformed.
In case of the difficulty with a
gas brazing machine
1. Disconnect the brazed part
where is easy to disconnect
and restore.
2. Cut pipes on the main unit
by a tube cutter in order to
make it easy to disconnect.
Note:
Do not use a metal saw for
cutting pipes by all means
because the sawdust come into
the circuit.
The brazed parts are hot
after being disconnected. To
avoid a burn, make sure that
the compressor is cooled
down before removing.
1Remove the flange nut
and open the terminal
cover. Release the
compressor lead wire.
2Unscrew the 3 nuts.
3Heat up and disconnect
the blazed parts.
Warning
Since it may happen
that refrigerant oil in
the compressor
catches fire, prepare
wet cloth so as to
extinguish fire
immediately.
Warning
Ventilate when
refrigerant leaks
during the work.
(If refrigerant contacts
fire, it causes to arise
toxic gas.)
Caution
From the viewpoint of
global environment
protection, do not
discharge the
refrigerant gas in the
atmosphere. Make
sure to recover the
refrigerant gas with
the recovery system.
