Ensure the following, in particular:-
1) The unit is mounted solidly and rigid in position.
2) Piping and connections are leak proof after charging.
3) Proper wiring has been done.
Drainage check:- Pour some water into left side of drain pan
(drainage are in right side of unit).
Test run:
1) Conduct a test run after water drainage test and gas leakage
test.
•
2) Watch out for the following:-
a) Is the electric plug firmly inserted into the socket?
b) Is there any abnormal sound from unit?

COOLING
PHASE SEQUENTIAL (3PH)
The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase sequential) is fitted
to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase sequential
operates, and the unit will not start. This device is located in the control box of the outdoor unit.
The following table shows the LED indicator light for phase sequential under normal operation and fault conditions.
