• Manifold Gauge will show cylinder pressure rather than suction pressure if the cylinder valve and Manifold valve "A"

are both open.

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

If there is any abnormal condition detected, 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 /

Indoor Coil Sensor Short /

Outdoor Coil Sensor Short

5. Gas Leak

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.

! CAUTION

There are many ways of charging liquid in a "controlled manner" into the suction

side:-

1. Use valve A on the manifold gauge set

2. Use the valve on the refrigerant cylinder

3. Charge through a Shredder valve

4. Use a hose with a Shredder valve depressor

5. Charge into the suction side at some distance from the compressor

6. All of the above
