Drainpipe Installation
The drainpipe is used to drain water away from
the unit. Improper installation may cause unit
and property damage.
• 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.
CAUTION
NOTE ON PURCHASING PIPES
NOTE ON DRAINPIPE INSTALLATION
Installation requires either 5/16" inner
diameter polyethylene tube or PVC drain
pipe sold separately.
• 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.
• Incorrect installation could cause water to
flow back into the unit and flood.
Indoor Drainpipe Installation
Install the drainpipe as illustrated in Figure 5.2.
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.
