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.

Locate the indoor unit at least 1 m or more away from a TV, radio, wireless appliance, antenna cable and
fluorescent light, and 2 m or more away from a telephone.

10.1.2 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 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.
10.1.3 Installing the Indoor Unit (Installation Embedded in the Ceiling)
10.1.3.1 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 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 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 1 m below the intake grill.
