3. Selecting an installation site
•
Select a location so that air can be blown into all corners of the room.
•
Avoid locations exposed to outside air.
•
Select a location free of obstructions to the airflow in and out of the unit.
•
Avoid locations exposed to stream or oil vapour.
•
Avoid locations where combustible gas may leak, settle or be generated.
•
Avoid installation near machines emitting high-frequency waves (high-frequency
welders, etc.)
•
Avoid locations where the airflow is directed at a fire alarm sensor. (Hot air
could trigger the alarm during the heating operation.)
•
Avoid places where acidic solutions are frequently handled.
•
Avoid places where sulphur-based or other sprays are frequently used.
Warning:
Install the indoor unit on a ceiling strong enough to sustain its weight.
If the ceiling lacks strength, it may cause the unit to fall down, resulting in an
injury.
3.1. Installation and servicing space
Refrigerant piping, drain piping, wiring, and other components should be installed
outside the
;
areas, and free of the access doors to ensure that they do not
hinder fan maintenance.

4.1. Fixing hanging bolts
(Use M10 hanging bolts. The bolts should be supplied in the field.)
(Give site of suspension strong structure.)
Hanging structure
•
Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
1
Reinforcing the ceiling with additional members (edge beam, etc.) must be
required to keep the ceiling at level and to prevent the ceiling from vibrations.
2
Cut and remove the ceiling members.
3
Reinforce the ceiling members, and add other members for fixing the ceiling
boards.
For wooden construction
•
Use the tie beam (for one story building) or second-floor beam (for two story
building) as strength members.
•
To hang the air-conditioner, use a hard square timber of more than 6 cm if the
distance between beams is less than 90 cm and a hard square timber of more
than 9 cm if the distance between beams is less than 180 cm.
