START-UP AND OPERATION

Start unit and check rotation of fans and compressors.

Scroll compressors will only compress in one rotational direction. Three phase compressors will rotate in either direction depending upon phasing of the power. Since there is a 50-50 chance of connecting power in such a way as to cause rotation in the reverse direction, it is important to ensure proper rotation direction is achieved when the system is installed and operated.

Monitor the microprocessor board for any fault codes. This will ensure proper unit operation. Verification of proper compressor direction is made by observing that suction pressure drops and discharge pressure rises when the compressor is energized. Reverse compressor rotation also results in an elevated sound level as well as substantially reduced current draw.

The Air Conditioning section of this equipment is charged with R-410A; a hi-pressure refrigerant. Only qualified technicians, using appropriately pressure-rated test instruments, should perform troubleshooting or service on this equipment.

There is no negative impact on durability caused by operating three phase Scroll compressors in the reversed direction for a short period of time (under one hour). However, after several minutes of operation the compressors internal protector will trip.

If opposite rotation is needed, disconnect and reverse any two leads of the three phase supply. Reconnect power.

Observe unit operation and check for unusual noise or vibration.
