ACCESSORIES

CHOOSING A SITE

Before choosing the installation site, obtain user approval.

Indoor unit

Optimum air distribution is ensured.

The air passage is not blocked.

Condensate can drain properly.

The ceiling is strong enough to bear the weight of the indoor unit.

A false ceiling does not seem to be at an incline.

Sufficient clearance for maintenance and servicing is ensured.

Piping between the indoor and outdoor units is within the allowable limits.
(Refer to the installation manual for the outdoor unit.)

The indoor unit, outdoor unit, power supply wiring and transmission wiring is at
least 1 meter away from televisions and radios. This prevents image interference
and noise in electrical appliances. (Noise may be generated depending on the
conditions under which the electric wave is generated, even if a one-meter
allowance is maintained.)

Use suspension bolts to install the unit. Check whether or not the
ceiling is strong enough to support the weight of the unit. If there
is a risk that the ceiling is not strong enough, reinforce the ceiling
before installing the unit.

Select the signal receiver mounting location within the signal
receiver mounting area according to the following conditions:

Since the receiver has a built-in temperature sensor, do not mount it in an area
where it will be subject to direct sunlight or to cold or hot air coming from the air
discharge grill of the air conditioner.

Since the receiver has a built-in light receptor to receive signals from the
wireless remote control, do not mount it in a location where the signal may be
blocked by a curtain, etc.

Wireless Remote Controller

Turn on all the fluorescent lamps in the room, if any, and find the site where remote control signals are properly received
by the indoor unit (within 4 metres).

Outdoor unit

For outdoor unit installation, see the installation manual supplied with the Multi outdoor unit.
