18.18. Inspecting the cooler and fan
The equipment, in particular the compressor
fan, cooler fan, and the cooler, must be kept
clean to ensure efficient drying. Remove dust
from the surface of the cooling fins and fans
by vacuuming or blowing down with
compressed air.
18.19. Replacement of solenoid valves
Risk of electric shock.
Shut off the compressed air
source, turn off the equipment
and disconnect it from the
mains before working on the
equipment.
Working with pressurised
pneumatic components poses a
risk of injury.
Disconnect the equipment from
the mains and vent the pressure
in the equipment and the
pneumatic
system to zero
before working on the
equipment.
In normal operation, the solenoid valves in the
bottom of the dryer must be replaced at the
defined interval.
