Removal Procedure 111
1.7 Removal of Indoor Heat Exchanger
Procedure Warning Be sure to wait for 10 minutes or more after turning off all power
supplies before disassembling work.
Step Procedure Points
1. Disconnect the refrigerant
piping.
Preparation
Remove the electrical box
according to the “Removal
of Electrical Box / Vertical
Blades”.
Caution
Be sure to stop the
compressor before
disconnecting the refrigerant
pipe. If the refrigerant pipe is
disconnected with the
compressor running and the
stop valve opened, air may be
sucked in to generate an
over-pressure in the
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 indoor unit

3
Pull out the drain hose.
Place a plastic sheet under
the drain hose as remaining
drain may leak.

Disconnect the flare nut
for gas piping with 2
wrenches.
Caution
From the viewpoint of global
environmental protection,
make sure to use a vacuum
pump for air purging.
When the pipings are
disconnected, protect the
both openings from entering
moisture.
