NOTE ON DRAINPIPE INSTALLATION
•
When using an extended drainpipe, tighten
the indoor connection with an additional
protection tube to prevent it from pulling
loose.
•
The drainpipe should slope downward at a
gradient of at least 1/100 to prevent water
from flowing back into the air conditioner.
•
To prevent the pipe from sagging, space
hanging wires every 1-1.5m (39-59”).
Indoor Drainpipe Installation
Install the drainpipe as illustrated in the following
Figure.
NOTE:
When connecting multiple drainpipes,
install the pipes as illustrated in the following
Figure.
Pass the drain hose through the wall hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slipping hazard.
NOTE:
The drainpipe outlet should be at least
5cm (1.9”) above the ground. If it touches the
ground, the unit may become blocked and
malfunction. If you discharge the water directly
into a sewer, make sure that the drain has a U
or S pipe to catch odors that might otherwise
come back into the house.

If the outlet of the drainpipe is higher than
the body’s pump joint, provide a lift pipe for
the exhaust outlet of the indoor unit. The
lift pipe must be installed no higher than
75cm (29.5”) from the ceiling board and
the distance between the unit and the lift
pipe must be less than 30cm (11.8”).
Incorrect installation could cause water to
flow back into the unit and flood.
To prevent air bubbles, keep the drain hose
level or slightly tiled up (<75mm / 3”).
