•Where the ceiling is strong enough to support the weight of
the unit and to prevent vibration and noise generation.
•Where sufficient clearance for maintenance and service can
be ensured (Refer to Fig. 1: = service space).
The power supply intake (1), drain connection (2), gas pipe
(3) and liquid pipe (4) connection should always be
accessible for maintenance and service.
•Where piping between indoor and outdoor units is possible
within the allowable limit. (Refer to the installation manual for
the outdoor unit.)
•There is no danger of fire due to leakage of flammable gas.
•Ensure that water can not cause any damage to the location
in case it drips out of the unit (e.g. in case of a blocked drain
pipe).
•Please consult with your dealer for installing in a special
environment (e.g. a place in oily surroundings, a place with
sulfide gas, a place where chemicals are used nearby, a place
with high voltage fluctuations, a place with volatile flammable
gas, a place in which machinery generates electromagnetic
waves.
2. Use suspension bolts for installation. Check whether the ceiling
is strong enough to support the weight of the unit or not.
If there is a risk, reinforce the ceiling before installing the unit.
PREPARATIONS BEFORE INSTALLATION
