Points
Caution
If gas leaks, repair the spot of
leaking, then collect all
refrigerant from the unit. After
conducting vacuum drying,
recharge proper amount of
refrigerant.
Caution
Do not contaminate any gas
(including air) other than the
specified refrigerant (R22 or
R410A, depending on the
model) into refrigerant cycle.
(Contaminating of 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
buried inside a wall, remove
it after the drain hose in the
wall is pulled out.
Use two wrenches to
disconnected pipes.
When disconnecting pipes,
cover every nozzle with caps
so as not to let dust and
moisture in.
