Removal of Heat Exchanger
Procedure
Warning
Be sure to turn off all power supplies at least 10 minutes before
disassembling work.
Step
Procedure
Points
1. Disconnecting the
refrigerant pipe
When reassembling, make
sure the drain hose is
sloped downward.
1
Remove the screws
which fix the heat
exchanger to the
installation plate.
2
Release the 2 hooks at
the bottom.
Lift the indoor unit by 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 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.
3
Lift up the indoor unit
body slightly and pull
out the drain hose. (In
the case of left piping)
Place a plastic bag 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 pipe
connection with 2 pair
of spanners.
Caution
From the point of view
of environmental
protection, be sure to
use a vacuum pump
for air purging.
Carry out the removal works
with 2 pair of spanners.
When the pipes are
disconnected, protect the
both openings of pipe side
and unit side from entering
of moisture.
