c) If your system contains a 60 Hz power cord, switch the black and red wires. If
your system contains a 50 Hz power cord, swap any two black wires.
6) Briefly energize the dedicated circuit breaker to bump start the motor. The motor
should now turn in the correct direction.
6.7 Connection of refrigerated air dryer (option)
If the optional refrigerated air dryer is not supplied with the system, proceed to the next
section.
The outlet port of the air compressor is connected to the inlet port of the refrigerated air
dryer with the 50 ft (15 m) roll of 3/8” OD copper tubing supplied with the air compressor.
To aid in the cooling of the compressed air and condensing the moisture entrained in it,
Cryomech recommends using the entire length of copper tubing to connect the air
compressor to the dryer.
The outlet port of the dryer is connected to the inlet port of the filter bank panel with the
50 ft (15 m) roll of 3/8” OD copper tubing supplied with the dryer.
