Lift the indoor unit by a wooden base. (Fig.34)
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 mix any gas (including air) other than the specified refrigerant
(R-410A) into refrigerant cycle.
If air or other contaminants mix with the gas, pressure will become
extremely high in the refrigerating cycle, which may cause a unit breakdown
or personal injuries.
