into the unit and flood.
•
To prevent air bubbles, keep the drain hose
level or slightly tiled up (<75mm / 3”).
The drainpipe is used to drain water away from
the unit. Improper installation may cause unit
and property damage.

Drainpipe Installation
CAUTION
•
Insulate all piping to prevent condensation,
which could lead to water damage.
•
If the drainpipe is bent or installed
incorrectly, water may leak and cause a
water-level switch malfunction.
•
In HEAT mode, the outdoor unit will
discharge water. Ensure that the drain hose
is placed in an appropriate area to avoid
water damage and slippage.
•
DO NOT
pull the drainpipe forcefully. This
could disconnect it.
•
•
•
•
When using an extended drainpipe, tighten
the indoor connection with an additional
protection tube. This prevents 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”).
If the outlet of the drainpipe is higher than
the body’s pump joint, use a lift pipe for the
indoor unit’s exhaust outlet. The lift pipe
must be installed no higher than 55cm
(21.7”) from the ceiling board. The
distance between the unit and the lift pipe
must be less than 20cm (7.9”). Incorrect
installation could cause water to flow back
NOTE:
When connecting multiple drainpipes,
install the pipes as illustrated in Fig 6.4.
NOTE ON PURCHASING PIPES
NOTE ON DRAINPIPE INSTALLATION
This installation requires a polyethylene tube
(outside diameter = 3.7-3.9cm, inside diameter
