22.2. Check of product operation

Check air pump condition
– the aggregates 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 cord, the connecting compressed air 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.

Compressor with air dryer - open the plug on the condensate collecting vessel and drain the
condensate.

Check the service indicator on the display screen and schedule service as needed.

Check the operating condition of the equipment (see Chapter 22.4).
22.3. Check the compressed air connections for leaks and inspect the equipment
Leak testing

Check the compressor's compressed air lines for leaks during operation
– pressure supplied by
the compressor.

Use a leak analyser or soapy water to check all joints and connections for leaks. Tighten or
reseal the connection where leaks are found.
Inspecting the equipment

Check the condition of the compressor aggregate for normal operation and noise levels.

Fan operation check
– the fans must be running during the defined compressor work cycles.

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 - 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.

Replace any defective parts as needed.

Check the solenoid valves in the valve module
– the valves should cyclically cycle between the
chambers based on the description of the operation.

Check the operating condition of the equipment (see Chapter 22.4).
22.4. Inspection of electrical connections
Risk of electric shock.
Inspect the product’s electrical connections when the mains are disconnected.

Check mechanical function of the main switch.

Check if the power cable and conductors are not damaged.
