UNIT HANGING
ACK-A ACK-B
•
Confirm the pitch of the hanging rod is 790.0mm X 620.5mm (ACK-A) / 600.0mm x 582.0 mm (ACK-B).
•
Hold the unit and hang it on the hanging rod with the nut and washer.
•
Adjust the unit height to 35.0 mm (ACK-A) / 25.0 mm (ACK-B) between the indoor unit bottom surface and the
ceiling surface.

DRAIN PIPING WORK
•
Drain pipe must be downward gradient for smooth drainage.
•
Avoid the drain pipe from up and down slope to prevent
reversal flow.
•
During the drain piping connection, be careful not to exert extra
force on the drain connector at indoor unit.
•
The outside diameter of the drain connection at the flexible
drain hose is 20 mm.
•
Be sure to provide heat insulation (polyethylene foam with
thickness more than 8.0 mm) on the drain piping to avoid the
condensed water dripping inside the room.
DRAIN TEST
•
Connect the main drain pipe to the flexible drain hose.
•
Feed water from flexible drain hose and check the piping for
leakage.
•
When the test is completed, connect the flexible drain hose to
the drain connector on the indoor unit.
Note: This indoor unit use drain pump for condensed water drainage. Installed
the unit horizontally to prevent water leakage or condensation around
the air outlet.
