• 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 installation within
the ceiling for improving the 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 within a ceiling, select the unit position and the airflow direction so that
the cool air and warm air spread throughout the whole room.
• Do not place objects that might obstruct the air flow within 1 m below the intake grille.
CAUTION
