Indoor Unit SiBE01-829
76 Removal Procedure
1.7 Removal of Heat Exchanger
Procedure Warning Be sure to wait 10 minutes or more after turning off all power
supplies before disassembling work.
Step Procedure Points
1. Disconnecting the
refrigerant pipe
Preparation
Remove the electrical box
according to the “Removal
of Electrical Box”.
Caution
In pump-down work, be sure
to stop the compressor
before disconnecting the
refrigerant pipe. If the
refrigerant pipe is
disconnected with the
compressor being operated
and the stop valve being
open, air may be sucked in to
generate an over-pressure in
refrigeration cycle, thus
resulting in pipe rupture or
accidental injury.
If the drain hose is
embedded in the wall,
disconnect the drain hose
beforehand.
1 Remove the screws
which fix the heat
exchanger to the
installation plate.
2
Lift the indoor unit by a
wooden base.
3 Place a plastic bag
under the drain pan to
prevent from wetting
the floor with remaining
drain.
4 Unscrew the flare nut
for gas piping by 2
wrenches.
Caution
From the point of view of
environmental protection, be
sure to use a vacuum pump
for air purging.
