Startup: Three Phase Compressor
All three phase motors can operate in either rotor
rotation direction depending upon how power is
supplied to the motor.
However, a THREE PHASE scroll compressor
will not work properly if run BACKWARDS.
If a three phase ice machine’s compressor is
making an unusually loud noise and the ice
machine does not appear to be refrigerating the
water, it’s likely that it’s running backwards. To
fix this two of the three compressor motor leads
need to be reversed.
1. Disconnect electrical power.
2. Remove left front panel.
3. Pull off compressor terminal cover.
4. Locate terminals, switch any two wires.
5. Return compressor terminal cover to its original
position.
6. Reconnect electrical power.
7. Push freeze button, compressor will start and
soon begin to cool the evaporators.
Electrical Shock Hazard
Disconnect electrical power
before beginning procedure.
