16.8. Inspecting the cooled 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.
16.9. Procedure for connecting a compressor disconnected from the cabinet
Prior to any maintenance or repair work, switch off the compressor and
disconnect it from the mains (pull out the mains plug).
The compressor (without cabinet) requires that the jumper is always mounted in the terminal strip
for correct operation (Fig. 9 pos. B). It then replaces the switch on the cabinet.
If there is no jumper in the terminal strip of the compressor (disconnected from
the cabinet), the compressor will not work!
If the cord between the compressor and the cabinet becomes disconnected (by pulling the mains
plug) and the compressor is removed from the cabinet, the compressor will not be functional. This
is why it is necessary to first create a connection to the terminal strip with a jumper (replacing the
circuit breaker function) (Fig. 9 pos. A).
PROCESS:
Jumper installation (A-B process)
Disconnect the product from the mains by pulling the plug out of the socket.
Remove the cover on the electrical panel (on the compressor).
The jumper is not in the terminal strip
– A.
Insert the jumper into the terminal strip
– B.
Reinstall the cover on the electrical panel.
Connect the device to the electrical mains.
Activate the compressor by turning on the switch on the pressure switch.,
Compressor - when operating outside the cabinet, the electrical connection with an installed jumper
must
be created.
