Do not install unit at a site where fire detector is located at the supply air side.
(Fire detector may operate erroneously due to the heated air supplied during
heating operation.)
•
When special chemical product may scatter around such as site chemical plants
and hospitals, full investigation is required before installing unit. (The plastic
components may be damaged depending on the chemical product applied.)
•
If the unit is run for long hours when the air above the ceiling is at high tempera-
ture/ high humidity (due point above 26 °C), due condensation may be produced
in the indoor unit. When operating the units in this condition, add insulation mate-
rial (10-20 mm) to the entire surface of the indoor unit to avoid due condensation.
3.1. Install the indoor unit on a ceiling strong enough
to sustain its weight
Warning:
The unit must be securely installed on a structure that can sustain its weight.
If the unit is mounted on an unstable structure, it may fall down causing inju-
ries.
3.2. Securing installation and service space
Secure enough access space to allow for the maintenance, inspection, and replace-
ment of the motor, fan, drain pump, heat exchanger, and electric box in one of the fol-
lowing ways.
Select an installation site for the indoor unit so that its maintenance access space will
not be obstructed by beams or other objects.

and the ceiling (Fig. 3.2.1)
• Create access door 1 and 2 (450 x 450 mm each) as shown in Fig. 3.2.2.
(Access door 2 is not required if enough space is available below the unit for a
maintenance worker to work in.)
and the ceiling (At least 20 mm of space should be left below the unit as shown in
Fig. 3.2.3.)
• Create access door 1 diagonally below the electric box and access door 3
below the unit as shown in Fig. 3.2.4.
or
• Create access door 4 below the electric box and the unit as shown in Fig. 3.2.5.
