When the air conditioner is installed in a small room, provide
•
appropriate measures to ensure that the concentration of
refrigerant leakage occur in the room does not exceed the critical
level.
•
Do not install in a location where fl ammable gas leaks are
possible. If the gas leak and accumulate around the unit, it may
ignite and cause a fi re.
Install the indoor unit at least 8'2" (2.5 m) above the fl oor level

is operated with the valve open and without refrigerant pipe,
the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause an injury.
Tighten the fl are nut with a torque wrench in the specifi ed
•
manner. Excessive tighten of the fl are nut may cause a crack in
the fl are nut after a long period, which may result in refrigerant
leakage.
