Operational checks
 Check air pump condition – the air pump s should be operating normally without excessive
vibration or noise. Troubleshoot any problem or call in service personnel if trouble is detected
 Visually inspect fan operation – the fans must be operating when the air pumps are running.
Troubleshoot any problem or call in service personnel if trouble is detected
 Check to ensure the power cable and pneumatic hoses are undamaged. Replace damaged
components or call in service personnel.
 Check the ambient temperature – the ambient temperature must be below the temperature limit
(40 °C). Cool the space if the temperature is high.
 On the compressor with dryer – open the plug on the condensate collecting bottle to drain the
condensate.
Pneumatic connection leakage check and device inspection
Leakage check:
 Perform the leakage check of pneumatic connections when the compressor is operating –
pressurizing.
 Use a leakage analyser or soapy water to check all joints and connections for leaks. Tighten or
reseal the connection where leaks are found.
Device inspection:
 Check the condition of the air pump for normal operation and noise levels.
 Fan operation check - the fans must be running during the defined compressor work cycles
 Check of temperature switch operation (B2) – heat the temperature switch to a temperature
above 40°C (e.g. using a heat gun, being careful not to warp any plastic pieces nearby). Fan
EV1 (and EV2 for a compressor with dryer) will start up once the temperature reaches 40°C so
long as power is connected to the compressor.
 Check filter condition – the filters must be undamaged and sufficiently clean.
 Check the condition of the air pump itself - ensure there is no contamination inside the
crankcase or play in the crankshaft
Replace any defective parts as needed.
Inspection of electrical connections
Check all electrical connections on the device with the mains disconnected!
Inspection
 Check the mechanical function of the main switch.
 Check to ensure the power cable and connected wires are undamaged.
 Visually inspect the connection of individual cables to the terminal strip.

Inspect all screw terminals for the protective green and yellow PE grounding conductor.
