(Summary description)

Fault phenomenon: The exhaust temperature of the unit is high (over 100 °C)
The unit coolant level is too low (should be visible in the oil sight glass, but not more than half);
Dirty oil cooler;
The oil filter element is blocked;
Temperature control valve failure (component is broken);
The oil-cut solenoid valve is not energized or the coil is damaged;
The diaphragm of the oil-cut solenoid valve is ruptured or aged;
Fan motor failure;
The cooling fan is damaged;
The exhaust duct is not smooth or the exhaust resistance (back pressure) is large;
The ambient temperature exceeds the specified range (38ΰŃ or 46ΰŃ);
Temperature sensor failure (Intellisys control unit);
Whether the pressure gauge is faulty (relay control unit).
Fault phenomenon: the oil consumption of the unit is large or the oil content of the compressed air is large

Too much coolant;
The oil return pipe is blocked;
The installation of the oil return pipe (the distance from the bottom of the oil separation core) does not meet the requirements;
Unit pressure is too low;
The oil separation core is broken;
The unit has oil leakage;
The coolant has deteriorated or has been used for an extended period of time.​​
.
Fault phenomenon: low unit pressure
