NOTICE: EQUIPMENT DAMAGE
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 (39-59in).
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 55cm
(21.7in) from the ceiling board. The distance between
the unit and the lift pipe must be less than 20cm (7.9in).
Incorrect installation could cause water to flow back into the
unit and flood.
To prevent air bubbles, keep the drain hose level or slightly
tilted up (<75mm / 3in).

4. Using a 65-mm (2.5in) core drill, drill a hole in the wall. Make sure that the
hole is drilled at a slight downward angle, so that the outdoor end of the
hole is lower than the indoor end by about 12mm (0.5in). This will ensure
proper water drainage (See Fig. 33). Place the protective wall cuff in the
hole. This protects the edges of the hole and will help seal it once you fi nish
installation.

NOTICE: PROPERTY DAMAGE
When drilling the hole, make sure to avoid wires, plumbing,
and other sensitive components.
5. 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.
NOTICE: PROPERTY DAMAGE
The drain pipe outlet should be at least 5cm (1.9in) above
the ground. If it touches the ground, the drain pipe may
become clogged and malfunction. If you discharge water
directly into a sewer, make sure that the drain has a U or
S pipe to catch odors that might otherwise come into the
house.
