Drainpipe lnstallation
The drainpipe is used to drain water away from
the unit. lmproper installation may cause unit
and property damage.
0CAUTION
• lnsulate all piping to prevent condensation,
which could lead to water damage.
• lf the drainpipe is bent or installed
incorrectly, water may leak and cause a
water-level switch malfunction.
• ln 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.
NOTE ON PURCHASING PIPES
This installation requires a polyethylene tube
(outside diameter= 3. 7-3.9cm, inside diameter
= 3.2cm), which can be obtained at your local
hardware store or dealer.
lndoor Drainpipe lnstallation
lnstall the drainpipe as illustrated in Figure 6.2.
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.

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.Sm {39-59").
• lf 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 (21.7") from the ceiling board. The
distance between the unit and the lift pipe
must be less than 20cm (7.9"). lncorrect
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 / 3").
