3. 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.
CAUTION
When drilling the wall hole, make sure to
avoid wires, plumbing, and other sensitive
components.
Step 9: Connect drain hose
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
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 = 3.7-3.9cm, inside diameter
= 3.2cm), which can be obtained at your local
hardware store or from your dealer.

Indoor Drainpipe Installation
Drain pipe
1. Make sure the drain pipe is connected to the
outdoor side downward.
2. The hard polyvinyl chloride(PVC)plastic pipe
(external diameter 26 mm) sold in the market
is suitable for the attached soft drain pipe.
3. Please connect the Soft Drain Pipe with the
Drain Pipe, then fix 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 Specific Gravity of 0.03, at
least 9 mm in thickness), and use Glue Band
to fix it.
4. After the Drain Pipe has been connected,
please check if the water drains out of the
pipe efficiently and has no leakage.
5. Refrigerant Pipe and Drain Pipe should be
heat-insulated to avoid condensing and
water-dropping later on.
6. Pass the drain hose through the wall hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slipping hazard.
NOTE: The drainpipe outlet should be at least
5cm (1.9") above the ground. If it touches the
ground, the unit may become blocked and
malfunction. If you discharge the water directly
into a sewer, make sure that the drain has a U
or S pipe to catch odors that might otherwise
come back into the house.
