Make sure the drain pipe has a downward gradient (1/100 or
more) and that there are no water traps.
3-5. Indoor Unit Drain Piping
●
During drain piping connection, be careful not to exert extra
force on the drain port at the indoor unit.
●
The outside diameter of the drain connection at the indoor
unit is 32 mm.
Piping material: Polyvinyl chloride pipe VP-25 and pipe
fittings.
●
Be sure to perform heat insulation on the drain piping.
Heat insulation material: Polyethylene foam with thickness
more than 8 mm (local supply).
●
Drain piping must have down-slope (1/50 to 1/100); be sure
not to provide up-and-down slope to prevent reversal flow.
●
Be sure to check no air trap on drain hose and to ensure
smooth water flow and no abnormal sound.

Drain Test
The air conditioner uses a drain up motor to drain water. Use
the following procedure to test the drain up motor operation.
●
Connect the main drain pipe to 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 up motor for normal operating and
noise when electric wiring is complete.
●
When the test is complete, connect the flexible drain hose to
the drain port.
