Prespraying (remove insects)
Foam is applied to the front half of the vehicle by the prespraying
nozzles. The foam is generated from water, prespraying agent
and compressed air.
Intensive Basic
Pre-cleaning chemicals are applied to the vehicle by stationary
nozzles.
The foam is generated from water, prespraying agent and com-
pressed air.
Wheel rim foam
Compressed air is used to spray a water-cleaning agent mixture
onto the wheel rims via 2 stationary foam nozzles.
High-pressure wash
The high-pressure wash removes coarse dirt from the surface of
the vehicle. High-pressure cleaning minimises the danger of
scratching from sand grains or similar abrasives and makes a sig-
nificant contribution to preserving the paintwork during cleaning.
Various different versions are available:
 Working pressure 16 bar (1.6 MPa)
 Working pressure 60 bar (6 MPa)
 Working pressure 70 bar (7 MPa), on-board high-pressure
pump (in the portal)
Foam wax is applied to the vehicle by the drying aid nozzles be-
fore the drying process.
Water mixed with wax is sprayed onto the vehicle via the cold wax
nozzles. Two different types of cold wax (wax 1 and wax 2) can
be selected.
Cleaning agent heater
The cleaning agent heater is located in the cleaning agent supply
in pillar 2.
Frost protection device
The washing bay can be equipped with a frost protection device:
If there is a danger of frost, the water is blown out of the piping
system automatically.
This blowing process is controlled by a thermostat.
Reverse osmosis system
Demineralised water (from an on-site system or optionally avail-
able reverse osmosis system) or fresh water dosed with drying
aid is sprayed onto the vehicle via the drying aid nozzles.
Foam polishing
A compressed air foamed mixture of water and cleaning agent is
sprayed onto the vehicle via 2 stationary nozzles. This is followed
by a polishing procedure with the washing brushes.
Safety switch
Safety switches are required if the required safety clearances be-
tween the washing bay and permanent fixtures (e.g. walls, pillars,
sinks) cannot be maintained. The safety switches prevent per-
sons from being crushed between the system and the wall.
The washing bay stops immediately if a safety switch touches an
obstacle.
Note
If the system is stopped by a safety switch, determine the cause
if this hand have the safety switch reset by an authorised techni-
cal specialist.
Splash guard
The splash guard protects the areas adjacent to the washing sta-
tion from sprayed dirt and splash water emitted by the rotating
side brushes.
The splash guard is attached to the outer surfaces of the chassis
and suspension as well as the pillars.
Foam wax
Cold wax
The purpose of the bollard protection is to ensure central align-
ment of the vehicle. They prevent the vehicle from being parked
too far away from the centre.
The on-site gate control is actuated by the passenger vehicle por-
tal controller with the correct signals according to the washing se-
quence.
A distinction is made between summer gate control and winter
gate control.
Summer gate control
 The gates are open before washing starts.
 The vehicle can drive in.
 The gates are closed when washing starts.
 The gates are opened when washing ends and remain open.
Winter gate control
 The entry gate is closed before washing starts and must be
opened to allow the vehicle to drive in. This is done by e.g. in-
serting a wash card into the wash card reader.
 The gates are closed when washing starts (e.g. by pressing
the "Start" button on the wash card reader).
 The gates are opened when washing ends and are closed
again after the vehicle has exited.
In the event of danger to persons, equipment or animals, the sys-
tem must be switched off immediately by pressing the "EMER-
GENCY OFF" button.
"EMERGENCY OFF" buttons are located:
 On the wash card/code reader.
 On the control panel.
 Optionally at the washing hall entrance if the control panel or
wash card/code reader are not located at the entrance.
The main switch is located at the main supply distributor.
Set the main switch to "1" to switch the system on.
At the key switch on the main supply distributor, see Supply dis-
tributorcan be used for selecting the operating stations from
which washing programs can be started.
 Position 0: Programme start not possible
 Position 1: Programme start possible at the wash card/code
reader
 Position 2: Programme start possible at the wash card/code
reader and at the control panel
Depending on the version of the Wash card/code reader, the
washing program can be selected as follows:
 Entry via a keypad.
 The program specified on the wash card.
 Entry of a code number.
Note
Further information is provided in the separate operating instruc-
tions for the wash card/code reader.
