6. Drainpipe installation
The drainpipe is used to drain water away from the unit.
Improper installation may cause unit and property damage.
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.
Indoor drainpipe installation
Install the drainpipe as illustrated in
Fig. 6.1
.
Fig. 6.1
1. Cover the drainpipe with heat insulation to prevent
condensation and leakage.
2. Attach the mouth of the drain hose to the unit’s outlet
pipe. Sheath the mouth of the hose and clip it firmly
with a pipe clasp.

Note on drainpipe installation
• 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.
• 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 from the ceiling board. The distance between
the unit and the lift pipe must be less than 20cm.
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).

NOTE:
If the drain pump spigot is not used, the drain
pump will still engage if the drain tray fills and activates
the water level sensor. This can lead to water leakage.
Possible actions to avoid water leakage:
1. Disconnect power to drain pump.
2. Plumb drain pump spigot into gravity fed drain.
