NOTE
The drainpipe outlet should be at least 5cm 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.
NOTE
When connecting multiple drainpipes, install the
pipes (as shown in Fig 6.5.) from pulling loose.
NOTE
When drilling the wall hole, make sure to avoid wires,
plumbing, and other sensitive components.
3. Using a 65-mm 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. This will ensure proper
water drainage (See Fig. 6.6). Place the protective wall
cuff in the hole. This protects the edges of the hole and
will help seal it when you finish the installation process.
4. 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 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 to prevent water
from flowing back into the air conditioner.
• To prevent the pipe from sagging, space hanging wires
every 1-1.5m.
• 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 from the ceiling board and the distance
between the unit and the lift pipe must be less than
30cm.
• Incorrect installation could cause water to flow back into
the unit and flood.
• To prevent air bubbles, keep the drain hose level or
slightly sloped (<75mm).
