Fault Diagnosis
If there is any abnormal condition detected, controller will blink the error code.
NOTE
The unit will not detect sensor missing when the compressor is ON.
Call your dealer immediately when this error happen.
There are many ways of charging liquid in a “controlled manner” into the suction
side:-
Use valve A on the manifold gauge set
Use the valve on the refrigerant cylinder
Charge through a Shredder valve
Use a hose with a Shredder valve depressor
Charge into the suction side at some distance from the compressor
All of the above

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.
