6.6 Frost Protection

Frost will destroy the appliance if it has not

that you empty the appliance or flush it with
antifreeze.

Emptying the appliance
Unscrew the water-inlet hose and the high-
pressure hose from the appliance.
Allow the appliance to run for max.
1 minute until the pump and the pipes are

Antifreeze
If the appliance is to be idle for extended
periods, we recommend that you pump
antifreeze through the appliance. This also
provides a certain degree of protection against
corrosion.
