NSTALLING
THE
INDOOR
UNIT
Selecting the location
The units are designed for ceiling concealed installation with an air
discharge duct of 500 mm.
Leave sufficient space for piping, servicing and electric wiring.
Be sure to install the unit so that:
■
the indoor and outdoor unit, the interconnection and the power
supply cable are at least 1 m away from televisions or radios.
This is to prevent interference from the air conditioner on your
televisions or radios.
■
the air will be distributed to the entire room.
■
the ceiling is strong enough to bear the weight of the indoor unit.
■
there are no obstructions for the air inlet and outlet.
■
the wall hole to the outdoor side for the electric wiring, the
refrigerant and drain piping can be made without problems in
terms of building structure.
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 big voltage
fluctuations, a place with volatile flammable gas, a place in which
machines generate electromagnetic waves).
