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 1 m or more away from a TV, radio, wireless appliance, antenna cable and fluorescent light, and 2

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.
• Waterproof the rear surface of the ceiling below the unit in consideration of water droplets forming and dropping.
• 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.
• 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 connecting
cables up to the respective piping and cable connection
positions.

piping, refrigerant piping and indoor/outdoor connecting
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.
CAUTION
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.
