PRODUCT MAINTENANCE
22.2. 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.
•
Open the plug on the condensate collecting bottle and drain the condensate.
22.3. 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 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.
22.4. 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.
•
Inspection of electrical connections on the AD dryer – see the service manual.
