11.1.3 INSTALLING THE INDOOR UNIT (INSTALLATION EMBEDDED IN THE CEILING)

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.
CEILING OPENING AND HANGING BOLT LOCATIONS

The relative positions of the ceiling opening and
hanging bolts are shown in the illustrations below.
When making an inspection opening below the
unit, make a 960 mm x 480 mm opening at the
ceiling surface. Also, lead the drain piping,
refrigerant piping and indoor/outdoor connection
cables up to the respective piping and cable
connection positions.

Secure the hanging bolts (M10, locally purchased)
firmly in a manner capable of supporting the unit
weight.

Consult your construction or interior contractor for details on finishing the ceiling opening.
