Hose clip (Accessory)
Heat insulator (Local
supply) (The thickness
must be at least 8 mm.)
It may be required to take off this part for checking or
servicing the drain up motor. Please do not glue.
Make sure that there is no clearance here.
NOTE
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.
