Install certainly the decorative panel.

Cool air leakage causes sweating. 

¤

Water drops fall.

• Drain piping must have down-slope (1/50 to

1/100): be sure not to provide up-and-down slope
to prevent reversal flow.

• 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 32mm.

• Be sure to execute heat insulation on the drain

piping.

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 flexible drain hose and check

the piping for leakage.

• Be sure to check the drain pump for normal oper-

ating and noise when electrical wiring is complete.

• When the test is complete, connect the flexible

drain hose to the drain port on the indoor unit.

Heat insulation material: Polyethylene foam with thickness more than 8 mm.
