Cause Remedy
– Loose cable – Check wiring
– Cleaning relay does not switch – Check/correct the settings of the
measuring system
– With heavy frost: Formation of ice in
the pump
– Warm up the Cleaning Air Box

shade the Cleaning Air Box better

page and cleaning duration for
future operation.

hose

ness and seal it

the sensor
– If necessary, install a check valve
(see section

the compressed air line
– Clean the cleaning nozzles and
compressed air line
– Install a check valve, especially
with great depths of immersion
(see section
3.6

– With heavy frost: Formation of ice in
the compressed air line
– Deice the compressed air line
– For future operation, lower the
ratio between stoppage and
cleaning duration
