Installation Procedure
CAUTION
• The indoor unit must be installed according to the
specified distances in order to permit accessibility
from each side, to guarantee correct operation,
maintenance, and repair of the unit.
The components of the indoor unit must be reachable
and removable under safe conditions for people and
the unit.
• Do not hold the discharge while carrying the indoor
unit to avoid the possibility of breakage.
• You must hold the hanger plate on the corner and
carry the indoor unit.
Step 3 Optional: Insulating the body
of the indoor unit
If you install a cassette type indoor unit on the ceiling
when temperature is over 27°C (80.6°F) and humidity is
over 80%, you must apply an extra 10 mm (0.39 in.) thick
polyethylene insulation or a similar type of insulation to
the body of the indoor unit.
Cut away the part where pipes are pulled out for the
insulating work.
Insulate the end of the pipe and some curved area by
using separate insulator.
