17.2. Check of product operation

Check pump condition
– the pumps must operate evenly without excessive vibrations or
noise. If there is any negative result, find the cause of the given condition or call service
engineers.

Check fans operation (visually)
– the fans must be operating when the fans are running. If
there is a negative result, look for the cause of the given condition or call service engineers.

Check if the power cord and pneumatic hoses are not damaged. Replace the damaged parts
or call service engineers.

Check ambient temperature
– ambient temperature must be below temperature limit (40°C).
Improve cooling in the room if the temperature is higher.

Compressor with air dryer - open the plug on the condensate collecting bottle and drain the
condensate,
17.3. Check of pneumatic connections leakage and device inspection
Leakage check

Check pneumatic connections of the compressor when the compressor is operating
–
pressurizing.

Use a leakage analyser or soapy water to check all connections for leaks. Tighten or release
the connection where leaks are found.
Device inspection

Check condition of the compressor pump
– even operation, appropriate noise level.

Check fans operation
– fans must be running in the defined cycles of the compressor
operation.

Check function of the temperature switch (B2)
– heat the temperature switch to temperature
above 40°C (e.g. using a heat gun – Be careful, do not operate with high temperature on
plastic components in the surrounding, it can cause deformation of plastic materials). Fan
E1, E3
starts up once the temperature reaches 40°C – the compressor must be under
voltage.

Check filters condition
– filters must be undamaged and sufficiently clean.

Check condition of the pump itself, check if there is no dirt inside the crankcase or clearance
in the crankshaft.

Replace any defective parts if there are any failures.
17.4. Check of electrical connections
Risk of electric shock.
Check electrical connections on the device disconnected from the mains.

Check mechanical function of the main switch.

Check if the power cable and conductors are not damaged.

Visually check if cables are connected to the terminal box.

Check all screw connections of the green-yellow PE grounding conductor.
