Installation
Drain piping must have down-slope (1/50 to 1/100): be sure not to
provide up-and-down slope to prevent reversal ow.
During drain piping connection, be careful not to exert extra force
on the drain port on the indoor unit.
The outside diameter of the drain connection on the indoor unit is
32 mm.
Be sure to install heat insulation on the drain piping.
Piping material: Polyvinyl chloride pipe VP-25 and
pipe ttings
The air conditioner uses a drain pump to drain water.
Use the following procedure to test the drain pump operation:
Connect the main drain pipe to the exterior
and leave it provisionally until the test
comes to an end.
Feed water to the exible drain hose and
check the piping for leakage.
Be sure to check the drain pump for normal
operating and noise when electrical wiring
is complete.
When the test is complete, connect the
exible drain hose to the drain port on the
indoor unit.
Heat insulation material: Polyethylene foam with thick-
ness more than 8 mm.
