Use adhesive tape for connecting the drain pipe.
(5) Pour water into the drain pan and check to
ensure that water can flow smoothly.
Do not connect the drain pipes with
sanitary or sewage or any other
drainage pipe.
When installing the pipe, do not tie the drain
pipe and refrigerant pipe together.
Pay attention to the thickness of the
insulation when the left side piping is
performed. If it is too thick, piping can not be

Turn OFF the main power switches to the
indoor unit and outdoor unit before
electrical wiring or periodical check, and
wait for at least 10 minutes.
Check to ensure the indoor and outdoor
fans have stopped before electrical wiring
or periodical check.
Protect the wires, drain pipes, electrical
parts, etc. from rats or other small animals.
If not protected, rats may gnaw at
unprotected parts, which may lead to a fire.
Avoid the contact of wires with the
refrigerant piping, sheet metal edges and
electrical components in unit. Otherwise,
the wires may get damaged or even cause
a fire.
Use ELB(earth leakage breaker) with
medium sensing rate (ELB with action time
being equal to 0.1 seconds or less). Failing
to do so may result in electric shock or a
fire.
The wires must be firmly secured. External
force applied to terminals may cause a fire.
It is forbidden to connect a plurality of
power lines into one power terminal block.
At the indoor unit side of air conditioner,
power wiring can be extended through a
power distribution box. Be sure to calculate
the wiring capacity carefully, since
excessively low wiring capacity may
frequently cause fire.
Do not start the system before all check
points are thoroughly checked.
