To protect from freeze damages, the appliance must be
flushed with antifreeze.
NOTE
Use normal glycol-based anti-freezing agents for automo-
biles.
NOTE
Observe handling instructions of the anti-freeze agent
manufacturer.
A certain corrosion protection is achieved with this as well.
NOTE
In the frost protection mode flow is recognised, however,
no pressure. This is OK in this operating mode and does
not lead to a fault message!
The fault message "water shortage" is deactivated with the
operating mode.
The frost protection mode has a maximum work time of 5
minutes, then the motor is switched off automatically.
In case of a faulty operation that leads to a pressure build-
up, the following could happen:
–
the safety valve opens or
–
the control switches off the diesel engine, as flow and
pressure are synchronous. After 5 seconds, the error
message ERROR 5 occurs
Prepare the antifreeze in the antifreeze container. Se-
lect the mixing ratio of the water/antifreeze as per the
instructions of the antifreeze manufacturer.
Check the antifreeze concentration with a commercially
available antifreeze tester and adapt if necessary.
With external water supply: Disconnect the water hose
from the water supply.
Unpressurize the appliance.
Open the supply tap of the water tanks and the drain
tap in order to completely drain the device. The filling
level indicator of the water tanks dips completely.
