23.2. 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 23.4).
23.3. 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.
 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 23.4).
23.4. 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.
 Visually check if cables are connected to the terminal box.
