2. Adjust the thermostat controller according to the ex-
terior temperature:
a If the exterior temperature is higher than -10 °C,
set the thermostat controller to the frost protec-
tion position.
b If the exterior temperature is lower than -10 °C,
set the thermostat controller to level "I".
Note: The frost protection device only works when the
system is switched on and the door is closed. The trig-
ger must therefore not be set to "0/OFF". The system
power supply must not be interrupted either. Operation
of the hot air blower is interrupted during operation of a
high-pressure pump.
DANGER
The hot air blower can overheat and cause a fire if
the air inlets and air outlets are covered.
Never cover the air inlets and air outlets of the hot air
blower.
ATTENTION
The frost protection cannot be maintained in the
event of a power failure.
Perform a frost protection shutdown in the case of a
power failure.
For a better overview, the maintenance work required to
ensure correct operation of the frost protection system
is summarised again here. To check the frost protection

Anti-freezing circulation circuit
If there is a risk of frost, circulating water flows through
the cleaning tools and their supply lines, thus protecting
them from freezing.
The anti-freezing circulation circuit is placed in opera-
tion by the anti-freezing pump.
The following components show that the system is
equipped with an antifreezing circulation:

Performed
Clean the filter and re-insert.
Remove and clean the filter (see "Cleaning the Power foam nozzle filter"). Determine
the following cleaning intervals according to experience.
Check for dirt and ice and lock the brush cleaning if necessary.
Is the hot air fan operating?
Is the setting of the thermostat regulator correct (warmer than -10 °C - level "I", colder
than -10 °C - level "II")?
Is the frost protection float tank outlet free?
See the section "Care and maintenance/Cleaning the sieve".
Clean the filter and re-insert.
Minimum value: approx. 0.5 l/min per washing tool (the tool with the lowest flow is de-
cisive).
Water quantity smaller with frost protection circuit: Clean the frost protection
pump filter, clean the sieve (on the frost protection ball tap), flush the line.
Larger water quantity for all tools: Regulate the water quantity with the frost protec-
tion ball tap.
Larger water quantity only at the high-pressure gun: Replace the node piece in
the high-pressure gun.
WARNING
The high-pressure gun can move uncontrollably and cause injuries if the frost
protection water quantity is too high.
Be sure to replace the node piece in the high-pressure gun if the frost protection water
quantity is too high.
Disconnection from system (option)
For disconnection from the water supply, the system is
supplied with water from a float tank with downstream
booster pump.

Shutting down
1. Turn the power switch to "0/OFF".
Shutdown in the case of potential frost
Shut down a system without frost protection (see "Shut-
ting down" chapter).
For a system with frost protection:
1. Leave the trigger at position "1".
2. Lock the washing station in the "Washing" menu
item of the control.

Frost protection with lost water
If there is a risk of frost, fresh water flows through the
cleaning tools and their supply lines, thus protecting
them from freezing. The water is then discharged into
the waste water system.
The presence of the frost protection solenoid valve indi-
cates that the system is equipped with this frost protec-
tion version.

scribed in the "Maintenance and care" chapter must
also be performed in winter.
Shutting down
If there is no danger of frost during the shutdown period:
1. Close off the water supply.
2. Switch off the power supply.
Shutdown in the case of potential frost
Perform the following additional steps in the case of po-
tential frost:
1. Empty all float containers.
2. Unscrew the hoses at the float containers and allow
them to drain completely.
3. Unscrew the hoses from the high-pressure pump
and allow the water to drain.
4. Unscrew the high-pressure hose from the pump
head and allow the water to drain.
5. Remove the detergent canister and store it in a
frost-protected place.
In case of doubt, have the maintenance performed by
Customer Service.
Additionally for the WSO attachment kit
1. Remove the RO membranes and store them in a
frost-protected place.
2. Empty the permeate buffer tank.
3. Flush the system (without base exchanger) with an-
tifreeze solution.
4. Rinse the base exchanger with concentrated salt
solution.
5. Blow out all parts containing water with oil-free com-
pressed air.
Note
During longer breaks in operation, the system, with the
exception of the base exchanger, must be flushed with
antifreeze solution to protect it from corrosion.
In case of doubt, have the shutdown performed by Cus-
tomer Service.
