11.1 Indoor Unit
11.1.1 Selecting the Installation Location
Take into consideration the following contents when creating the blueprint.
■Indoor unit installation location
Do not install the unit in excessive oil fume area such as kitchen, workshop and etc.
The location should be strong enough to support the main unit without vibration.
There should not be any heat or steam source nearby.
Drainage should be easy. Avoid locating the drain port close to ditches (domestic wastewater).
Avoid locations above entrances and exits.
Do not block the air intake and discharge passages.
Select the location that enables the cool and warm air to spread out to the entire room.
Locate the indoor unit at least 3.28 ft (1 m) or more away from a TV, radio, wireless appliance, antenna cable and
fluorescent light, and 6.56 ft (2 m) or more away from a telephone.
Recommended installation height for indoor unit shall be at least 8.27 ft (2.5 m) from floor.
11.1.2 To Drill a Hole in the Wall and Install a Sleeve of Piping
1 Insert the piping sleeve to the hole.
2 Fix the bushing to the sleeve.
3 Cut the sleeve until it extrudes about 19/32"
(15 mm) from the wall.
When the wall is hollow, be sure to use the sleeve for tube
assembly to prevent pests from damaging the cables, e.g.
mice biting the connection cable.
4 Finish by sealing the sleeve with putty or
caulking compound at the final stage.

11.1.3 Installing the Indoor Unit (Installation Embedded in the Ceiling)
11.1.3.1 Preparation Before Installation
Always provide sufficient entry and exit space to allow installation work, inspection and unit replacement.
Waterproof the rear surface of the ceiling below the unit in consideration of water droplets forming and dropping.
When cooling operation is performed for an extended period under the following conditions, water droplets may form and drop. Attach locally
purchased insulation (foamed polyethylene with a thickness of 7/32" (5 mm) or more) to the outside of the indoor unit before installing into the
ceiling to improve heat insulation.
Locations with a dew point inside the ceiling of 73.4°F (23°C) or more
Kitchens and other locations that produce large amounts of heat and steam
Locations where the inside of the ceiling serves as an outside air intake passage
When installing into a ceiling, select the unit position and airflow direction that enable the cool and warm
air to spread out to the whole room.
Do not place objects that might obstruct the airflow within 3.28 ft (1 m) below the intake grill.

Ceiling Opening
Install inspection opening 17 23/32" x 17 23/32" (450 mm x 450 mm) on the control box side where maintenance
and inspection of the control box and drain pump are easy. Install another inspection opening 31 1/2" x 27 9/16"
(800 mm x 700 mm) also at the lower part of the unit.
