22.10. Check of solenoid valve operation
Check their operation using the
“Magnetic indicator” fixture as follows:

Attach the fixture to the valve coil and if the
motors are active at the valve coil, the
indicator must rotate and if they are out of
inactive, the indicator must not rotate.

22.11. Check the function of the
pressure switch
Every pressure switch has a defined
hysteresis of ~2 bar. Functionality is checked
visually. If the air pumps reach the upper limit,
the pressure switch must disconnect the
motors from the power. The process is
reversed and the motors started at the low
pressure limit.
22.12. Dew point sensor calibration
It is recommended to calibrate the dew point
sensor every 2 years on compressors
equipped with this sensor. Calibration is
performed by the manufacturer (Vaisala) and
must be ordered online.
Sensor calibration ordering process:

Visit the website www.vaisala.com ,
and then navigate to the Services
section and select Calibration and
repair services .

Then enter the type of sensor (sensor
type: DMT143 ) and select a calibration
type, then follow the provided
instructions.
22.13. Cleaning and disinfection of the
exterior surfaces of the product
Clean and disinfect the exterior surfaces with
neutral cleaning products.
Use of aggressive detergents
and disinfectants containing
alcohol and chlorides can lead
to
surface damage and
discolouration.
23. LONG-TERM SHUTDOWN
If the compressor will not be used for a
prolonged time period, it is recommended to
drain all condensate from the air tank and the
condensate separator. Then turn on the
compressor for 10 minutes, keeping the drain valve on the air tank open. Switch off the
compressor using the main switch, close the
condensate drain valve and disconnect the
equipment from the mains.
24. DISPOSAL OF DEVICE

Disconnect the equipment from the
mains.

Release the air pressure in the
pressure tank by opening the drain
valve.

Dispose of the equipment following all
applicable regulations.

Entrust a specialised company to sort
and dispose of waste.

Worn out components have no
negative environmental impact.
