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.
NOTICE
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.

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.
Compressed air
Water
Detergent
Automatic change-over (option)
The automatic change-over modifies the
quality of the foam when the temperature
set in the control is exceeded.
At an additional pressure reducer for air a
wetter foam quality is selected in order to
adjustment
prevent excessively fast drying of the foam
knob (%)
in high ambient temperatures.
