Connect the drain hose to the drain raising pipes, and
insulate them.
Connect the drain hose to the drain outlet on the indoor unit,
and tighten it with the clamp.
Precautions
Install the drain raising pipes at a height of less than
20.9 in/530 mm.
Install the drain raising pipes at a right angle to the indoor
m
unit and no more than 11.8 in/300 mm from the unit.
To prevent air bubbles, install the drain hose level or slightly
tilted up (_<3 in/75 mm).
The incline of drain hose should be 3 in/75 mm or less so
that the drain socket does not have to withstand additional force.
To ensure a downward slope of 1:100, install hanging
bars every 3.3ft/1 m to 4.9ft / 1.5 m.
[]
When unifying multiple drain pipes, install the pipes as
shown in figure below. Select converging drain pipes whose
gauge is suitable for the operating capacity of the unit. []

Drain piping connections
Do not connect the drain piping directly to sewage
pipes that smell of ammonia. The ammonia in the
sewage might enter the indoor unit through the drain
pipes and corrode the heat exchanger.
Keep in mind that it will become the cause of
drain pipe blockage if water collects in the drain pipe.
After the piping work is finished, check if drainage flows smoothy.
Add approximately 1L of water gradually through the air discharge
outlet.

5 ELECTRIC WIRING WORK
General instructions
All field wiring and components must be installed by a licensed
electrician and must comply with relevant
regulations.
[] Use copper wire only.
[] Follow the 'Wiring diagram' attached to the unit body to wire the
outdoor unit, indoor units and the remote controller.
A circuit breaker capable of shutting down power supply to the
entire system must be installed.
Note that the operation will restart automatically if the main
power supply is turned off and then turned back on again.
[] Be sure to ground the air conditioner.
Do not connect the ground wire to gas pipes, water pipes,
lightning rods, or telephone ground wires.
Gas pipes: might cause explosions or fire if gas leaks.
Water pipes: no grounding effect if hard vinyl piping is used.
Telephone ground wires or lightning rods: might cause
abnormally highelectric potential in the ground during
lightning storms.
