It is intendedto prevent cooling capacity deterioration byeliminating dust adhering to the condenser from theair intake.Detects the inlet air temperature.Tripped when high-pressure alarm is activated. It isintended to protect the refrigerant system for thecondenser etc.Tripped when compressor head high-temperaturealarm is activated. It is intended to protect thecompressor.Tripped when over-current flows through the circuit.It is intended to protect the internal electric wiring.During warm-up in winter, the electric heater heatsup the oil to a preset temperature.Intended for the different-voltage model.OILCON operation panel (See page .)No. Name Function No. Name Function16–E
