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

(outside diameter = 3.7-3.9cm, inside diameter
= 3.2cm), which can be obtained at your local
hardware store or from your dealer.

is suitable for the attached soft drain pipe.
3. Please connect the Soft Drain Pipe with the
Drain Pipe, then x it with band; if you have
to connect the Drain Pipe indoors, to avoid
condensing caused by air intake, you must
cover the pipe with heat-insulation material
(polyethylene with Speci c Gravity of 0.03, at
least 9 mm in thickness), and use Glue Band
to x it.

slight downward angle, so that the outdoor
end of the hole is lower than the indoor end

water drainage (See Fig. 10.2). Place the
protective wall cu in the hole. This protects
the edges of the hole and will help seal it
