Removal Procedure
1.7
Removal of Indoor Heat Exchanger
Procedure
Warning
Be sure to turn off all power supplies at least 10 min. before
disassembling work.
Step
Procedure
Points
1. Disconnect the refrigerant
piping.
1
Remove the screws
which fix the indoor
heat exchanger to the
installation plate.
2
Lift the indoor unit with
a wooden base.
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 operating and
the stop valve open, air may
be sucked in to generate an
over-pressure in refrigeration
cycle, thus resulting in pipe
rupture or accidental injury.
3
Lift up the indoor unit
slightly and pull out the
drain hose. (The
illustration is for the
case of left piping.)
Place a plastic sheet under
the drain pan to prevent
from wetting the floor with
remaining drain.
If the drain hose is
embedded in the wall,
disconnect the drain hose
beforehand.
4
Disconnect the piping
connection with 2
wrenches.
Caution
From the viewpoint of
global environment
protection, be sure to
use a vacuum pump
for air purging.
Carry out the removal works
with 2 wrenches.
When the pipings are
disconnected, protect the
both openings of pipe side
and unit side from entering
of moisture.
