Drainpipe Installation
6 Drainpipe Installation
The drainpipe is used to drain water 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 malfunction of the water level switch.
• 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 due to frozen drain water.
• DO NOT pull the drainpipe forcefully, as this could cause it to
disconnect.
NOTE ON PURCHASING PIPES
This installation requires a polyethylene tube (outside diameter = 37-
39mm, inside diameter = 32mm), which can be obtained at your local
hardware store or from your dealer.
Indoor Drainpipe Installation
Install the drainpipe as shown in Figure 20.
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. (Fig. 19)

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
1-1.5m.
• 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 750 mm from the ceiling
board, and the distance between the unit and the lift pipe must be
less than 300 mm. 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
(<75 mm).

3. Using a 65 mm core drill, drill a hole in the wall. Ensure that the
hole is drilled at a slightly downward angle, so that the outdoor end
of the hole is lower than the indoor end by about 12mm. This will
ensure proper water drainage (See Fig.23). 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.
