Formula:
1.
MCA = (1.25*MOC compressor 1 + (Qty of compressor
–
1)* MOC comp (Qty of fan)* FLA of
fan
2.
MOCP = (2.25* MOC compressor 1 + (Qty of compressor
–
1)* MOC comp (Qty of fan)* FLA of
fan
Phase Sequence for Correct Compression
Scroll compressor require proper phase sequence to secure correct rotation
direction and therefore compression. The phase sequence has to be secured
between network to the compressor.
Correct Fan Motor Rotation
Verify correct rotation of fan motor by ensuring cold air discharged from unit.
Swap any two live wires on the incoming supply to the fan contactors if fan motor
reverse direction.
