CAUTION
• Install the indoor and outdoor units, power supply wiring and
connecting wires at least 3.3 ft (1 m) away from televisions or
radios in order to prevent wave interference or noise.
(Depending on the radio waves, a distance of 3.3 ft (1 m) may
not be sufficient enough to eliminate the noise.)
• In the case of the installation of a wireless remote controller, the
transmission distance of the wireless remote controller may be
shortened if the room has a fluorescent light of electronic light-
ing type (i.e., an inverter or rapid-start fluorescent light).
Keep the distance between the receiver and the fluorescent
light as far as possible.
(2) Use hanging bolts to install the indoor unit. Check that the
place of installation withstands the weight of the indoor unit.
Secure the hanging bolts with proper beams if necessary.

PREPARATIONS BEFORE INSTALLATION
(1) Check the positional relationship between the ceiling open-
ing hole and the hanging bolt of the unit.
• For the maintenance, inspection, and other servicing
purposes of the control box and drain pump, prepare one
of the following service spaces.
1. Inspection hatch 1 (17-3/4 in. (450 mm) × 17-3/4 in.
(450 mm)) for the control box and a minimum space of
12 in. (300 mm) for the lower part of the product.
(Refer to Fig. 2-2)
2. Inspection hatch 1 (17-3/4 in. (450 mm) × 17-3/4 in.
(450 mm)) for the control box and inspection hatch 2
for the lower part of the product (see arrow view A-1).
(Refer to Fig. 2-3)
3. Inspection hatch 3 for the lower part of the product
and the lower part of the control box (see arrow view
A-2).

• The H1 dimension indicates the
height of the product.
• Determine the H2 dimension by
maintaining a downward slope of
at least 1/100 as specified in
