temperature is reached.
 Switch off the appliance and let it stand
for 20 minutes. The hand-spray gun
must remain opened.
 Then pump out the machine until empty.
Note: As an anti-corrosion measure and for
neutralising the acid residue, we recom-
mend that you finally pump an alkaline so-
lution through the machine (for e.g. RM 81)
via the detergent tank.
Frost protection
ATTENTION
Risk of damage! Freezing water in the ap-
pliance can destroy parts of the appliance.
– Store the appliance in a heated room
during winter or empty it. During longer
breaks in operation, it is advisable to
pump in anti-frost agents into the appli-
ance.
– If it is not possible to store frost free,
shut down device.
 Drain water:
 Screw off water supply hose and high
pressure hose.
 Screw off supply hose at boiler bottom
and drain heating spiral empty.
 Operate device for max. 1 minute until
the pump and conduits are empty.
 Flush appliance with anti-freeze agent:
Note: Observe handling instructions of the
anti-freeze agent manufacturer.
 Fill anti-freeze agent of the trade into
swimmer container.
 Switch on appliance (without heater) till
the appliance has been completely
rinsed.
A certain corrosion protection is achieved
with this as well.
