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 disassembly work.
Step
Procedure
Points
1. Disconnect the refrigerant
piping.
Caution
If gas leaks, collect all
refrigerant from the unit, then
repair the spot of leaking. After
conducting vacuum drying,
recharge proper amount of
refrigerant.
Caution
Do not contaminate with any
gas (including air) other than
the specified refrigerant (R-
410A) into refrigerant cycle.
Contaminating with air or other
gas causes abnormal high
pressure in refrigerating cycle,
and this results in pipe
breakage or personal injuries.
Pay attention so that the
residual water in the drain will
not make the floor wet.
In case that a drain hose is
buried inside a wall, remove it
after the drain hose in the wall
is pulled out.
1
Hold the indoor unit up
by a piece of wood etc.
2
Unscrew the flare nut for
gas piping and liquid
piping by 2 wrenches.
Use 2 wrenches to
disconnected pipes.
When disconnecting pipes,
cover every nozzle with caps
so as not to let dust and
moisture in.
