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.
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.
Indoor Drainpipe Installation
Install the drainpipe as illustrated in Fig5.2.
Cover the drainpipe with heat insulation to
1.
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 rmly with a pipe clasp.

NOTE ON DRAINPIPE INSTALLATION
When using an extended drainpipe,
tightenthe indoor connection with an
additionalprotection 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 (39-59").
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 (21.7") from the ceiling board. The
distance between the unit and the lift pipe
must be less than 20cm (7.9"). Incorrect
installation could cause water to ow back
into the unit and ood.
To prevent air bubbles, keep the drain
hose level or slightly tiled up (<75mm / 3").
