The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is Þ tted
to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase sequencer
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 protector under normal operation and fault conditions.
NOTE
1. “+” indicates additional functions for PP01 phase protector.
2. When R phase missing, no LED or buzzer will indicate the error, but relay 71 and relay 81 will cut off.
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 Þ rmly inserted into the socket?
b) Is there any abnormal sound from unit?
c) Is there smooth drainage of water?
Check that:
Condenser fan is running, with warm air blowing off the
condensing unit.
Evaporator blower is running and discharge cool air.
The remote controller incorporates a 3 minute delay in the
circuit. Thus, it requires about 3 minutes before the outdoor
condensing unit can start up.

- Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air ow select the coolest possible place where intake air should not be hotter than the outside temperature refer to operating range 11
- Refrigerant piping 11
- Remark for fdm60jev1k cooling unit recommended to add 6 kg external accumulator 11
- When the pipe length becomes too long both the capacity and reliability drop as the number of bends increases system piping resistance to the refrigerant ow increases thus lowering the cooling capacity as a result compressor reliability will be affected always choose the shortest path and follow the recommendation as tabulated below 11
