ELECTRICAL WORK
Test running
Perform test operation after completing gas leak check at the pipe connections and
electrical safety check.
Check that all tubing and wiring have been properly connected.
Check that the coupling connection on the outdoor unit is completely secure and aligned.
1. Connect the power, press the ON/OFF button on the remote controller to turn the unit on.
2. Use the MODE button to select COOL, HEAT, AUTO and FAN to check if all the functions
works well.

3. When the ambient temperature is too low(lower than 17 C), the unit cannot be tested via
the remote controller to run at cooling mode.
Carry out a manual testing via a manual control button located in the indoor unit (as
illustrated below). The remote controller must be disabled first.
To locate the manual control button, open the indoor unit panel by holding the panel
sides and lifting the panel up to an angle until it remains fixed with a clicking sound.
Press the Manual control button to select AUTO or COOL, this will force the operation
of AUTO or COOL(see User Manual for details).
4. The test operation may last about 30 minutes.

1) Be sure to use a dedicated power circuit specifically for the air conditioner.
2) The screws fastening the wiring in the casing of electrical fittings may become
loose from vibrations and transportation. Tighten all terminal screws securely.
Check and make sure they are tightly
3) Check the specification of power source is correct.
4) Confirm that electrical capacity is sufficient.
5) Make sure the starting voltage is maintained at more than 90 percent of the rated
voltage marked on the name plate.
6) Always install an earth leakage circuit breaker in a wet or moist area.
7) A vibration of a magnetic switch may damage the contact point, causing fuse
break to fail or the normal function of an overload to fail.
8) Do not turn on the safety breaker until all work is completed.
9) Use an all-pole disconnection type breaker with at least 3mm between the contact
point gaps.
