Compressor type Extreme
1 Pressure reducer
2 Manometer
 Set pressure reducer to 0.4...0.5 MPa
(4...5 bar).
Setting dosing pumps
1 Dosing pump high pressure wash (DP
1)
2 Dosing pump hot wax (DP 2)
3 Dosing pump top care (DP 3)
4 Dosing pump optional (DP 4), for addi-
tional programmes
The dosing pumps dose the washing water
with the detergents in accordance with the
wash programme and the equipment of the
system.
Note
The dosage amount is optimally set by the
fitter when the plant is assembled. General-
ly no reset is necessary.
Fine adjustments are made on the control
(see Settings/Control). The basic settings
of the dosing pumps remains unchanged.
Basic adjustment
1 Ventilation lever
2 Ventilation button
3 Adjustment knob dosing volume
 Pull out the adjustment knob for the
dosing volume.
 Press and release the ventilation button
repeatedly and at the same time, rotate
the adjustment knob to the desired set-
ting.

Foam / polish station
The operation of the foam station and the
polish station does not differ. Thus, the fol-
lowing description applies for both types.
1 Pressure reducer air
2 Manometer compressed air
3 Detergent dosing
4 Detergent suction hose with filter
5 Manometer water
6 Pressure reducer water
The assembly is adjusted by the technician
during commissioning.
 Adjust the quality of the foam on the
pressure reducer air only.
Note:
The set foam quality only remains consist-
ent if there are no bubbles in the detergent
suction hose.
Basic adjustment
 Start foam programme to be set.
 Perform default settings in accordance
with the following table.

Automatic change-over (option)
The automatic change-over modifies the
quality of the foam when the temperature

wetter foam quality is selected in order to
prevent excessively fast drying of the foam
in high ambient temperatures.
