2. Charging procedures – Three phase compressors
The fundamental procedure is the same as for single phase models but the compressor can run in the wrong direction on
starting. If this happens reverse any two phases and start again. Short term reverse rotation will not damage the compressor.
All Specter compressors have internal discharge temperature protectors which are very effective in preventing dangerously
high discharge temperatures during charging. The protection module will trip and lock the compressor out for 30 minutes.
It is not normally necessary to wait 30 minutes for the module to reset. When the compressor has cooled down the module
can be reset by breaking the power supply to the control circuit. Very often the serviceman does not understand why the
module tripped and uses a jumper wire to bypass it. He continues to charge the system and removes the jumper when
charging is complete. The compressor may or may not run with the protector back in the circuit but it is certain that the
compressor has been damaged and premature failure is inevitable.

FAULT DIAGNOSIS

Wired Controller

If there is any abnormal condition detected, wired controller will blink the error code.
Event
1. Room Sensor Open or Short
2. Indoor Coil Sensor Open
3. Outdoor Coil Sensor Open
Compressor Overload /
4. Indoor Coil Sensor Short /
Outdoor Coil Sensor Short
5. Low Refrigerant Charge/Gas Leak/Outdoor Abnormal
6. Water Pump Fault
7. Outdoor Coil Sensor Exist (MS model)
8. Hardware Error (tact switch pin short)
NOTE
The unit will not detect sensor missing when the compressor is ON.
Call your dealer immediately when this error happen.
