- Be sure to execute heat insulation on the
drain piping.
Indoor Unit Drain Piping
- 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.
Piping material: Polyvinyl chloride pipe VP-
25 and pipe fittings
Drain test
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
operating and noise when electrical wiring is
complete.
- When the test is complete, connect the flexi-
ble drain hose to the drain port on the indoor
unit.

HEAT INSULATION
- Use the heat insulation material for the
refrigerant piping which has an excellent
heat-resistance (over 120°C).
