Î Refill the antifreeze container with anti-
freeze. Select the mixing ratio of the
water/antifreeze as per the instructions
of the antifreeze manufacturer.
Î Align the actuation lever of the ball tap
for antifreeze/water tank vertically.
Î Unscrew the high pressure hose from
the high pressure outlet.
Î Connect the antifreeze hose between
the high pressure outlet and the anti-
freeze return.
Î Plug in the antifreeze plug control line.
Î Turn the key switch to the right.
The control voltage is switched on and the
display shows the antifreeze rinse opera-
tion.
Î Press the F2 key to start the motor.
Î Let the motor run until antifreeze is vis-
ible in the antifreeze hose.
The antifreeze liquid is pumped through
the appliance in a circuit.
Note
After each antifreeze flush, the antifreeze
concentration must be tested in the hose
with a commercially available antifreeze
tester in the return flow from the hose. Add
more antifreeze as needed if the concen-
tration is too low.
Î Press the F3 key to shut off the motor.
Wait for the motor to stop trailing.
Î Remove the antifreeze hose between
the high pressure outlet and the anti-
freeze return.
Î Check the coolant circuit of the motor
for sufficient antifreeze, refill antifreeze
as needed.
See Maintenance Procedures "Check and
refill the coolant“.
Î If the appliance is not used for an ex-
tended period and if there is frost, re-
move the battery and store it in a
location protected from frost.
Note
Prior to operation, the antifreeze must be
pumped from the high pressure system
back into the antifreeze container.
Î Unpressurize the appliance.
Î Swivel the actuation lever of the ball tap
for antifreeze/water tank to the right.
Î Connect the antifreeze hose between
the high pressure outlet and the anti-
freeze return.
Î Create a water supply connected to the
system separator.
Î Turn the key switch to the right.
The control voltage is switch on and the
display shows the operating status.
The solenoid valve for the water supply will
open.
Î Plug in the antifreeze plug control line.
Î Press the F2 key to start the motor.
Î The antifreeze liquid is routed into the
antifreeze tank with fresh water from
the fresh water reservoir.
Î Rinse for about 2 minutes. Watch the
antifreeze hose until no more antifreeze
can be seen.
Î Press the F3 key to shut off the motor.
Wait for the motor to stop trailing.
Î Remove the antifreeze hose between
the high pressure outlet and the anti-
freeze return.
