Choosing an Installation Site
• Before choosing the installation site, obtain user approval.
1.
Indoor unit
CAUTION
• When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs. Do not exert any pressure on
other parts, especially the refrigerant piping, drain piping and flange parts.
Wear protective gear (such as gloves) when installing the unit.
• If you think the humidity inside the ceiling might exceed 86°F (30°C) and RH80%, reinforce the insulation on the unit body.
Use glass wool or polyethylene foam as insulation so that the thickness is more than 0.4in (10mm) and fits inside the ceiling
opening.
• 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 3.3ft (1m) away from televisions and radios. This prevents image interfer
-
ence and noise in electrical appliances. (Noise may be generated depending
on the conditions under which the electric wave is generated, even if a 3.3ft
(1m) 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.
(Installation pitch is marked on the carton box for installation. Refer to it to check
for points requiring reinforcing.) Select the *H dimension such that a downward
slope of at least 1/100 is ensured as indicated in “
Drain Piping Work
”.
• The installation pitch is listed on the packing material, and should be checked
when deciding whether to reinforce the location or not.

Select the signal receiver mounting location according to the
following conditions:
• Install the signal receiver, which has a built-in temperature sensor, near the
intake vent where there is convection of air and it can get an accurate reading
of the room’s temperature. If the intake vent is in another room or the unit
cannot be installed near the intake vent for any other reason, install it 5ft
(1.5m) above the floor on a wall where there is convection.
• In order to get an accurate reading of the room’s temperature, install the signal
receiver in a location where it is not exposed directly to cold or hot air from the
air discharge grille or to direct sunlight.
• Since the receiver has a built-in light receptor to receive signals from the
wireless remote controller, do not mount it in a location where the signal may
be blocked by a curtain, etc.
Air outlet grille:
Wooden or plastic grille is recommended
because condensation may occur
depending on humidity conditions.
CAUTION
If the signal receiver is not installed in a location where there is convection of air, it may be unable to get an accurate reading
of the room’s temperature.
