Drain test
Use the following procedure to test the drain
pump operation:
- Set the air direction louvers up - and - down
to the position(horizontally) by hand.
- Pour a glass of water on the evaporator
using a kettle.
- Ensure the water flows through the drain
hose of the indoor unit without any leakage
and goes out the drain exit.
[Ceiling suspended type]
- 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.
- Remove the rubber stopple before
connecting drain hose.
- Hook on the bracket after connecting the
drain hose as below.
