ÎRefill the antifreeze container with anti- freeze. Select the mixing ratio of the water/antifreeze as per the instructions of the antifreeze manufacturer.
ÎAlign the actuation lever of the ball tap for antifreeze/water tank vertically.
ÎUnscrew the high pressure hose from the high pressure outlet.
ÎConnect the antifreeze hose between the high pressure outlet and the anti- freeze return.
ÎPlug in the antifreeze plug control line.
ÎTurn the key switch to the right.
The control voltage is switched on and the display shows the antifreeze rinse opera- tion.
ÎPress the F2 key to start the motor.
ÎLet 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.
ÎPress the F3 key to shut off the motor. Wait for the motor to stop trailing.
ÎRemove the antifreeze hose between the high pressure outlet and the anti- freeze return.
Antifreeze motor
ÎCheck the coolant circuit of the motor for sufficient antifreeze, refill antifreeze as needed.
See Maintenance Procedures "Check and refill the coolant“.
Battery
ÎIf 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.
Pumping antifreeze out of the high
pressure system
Note
Prior to operation, the antifreeze must be pumped from the high pressure system back into the antifreeze container.
ÎUnpressurize the appliance.
ÎSwivel the actuation lever of the ball tap for antifreeze/water tank to the right.
ÎConnect the antifreeze hose between the high pressure outlet and the anti- freeze return.
ÎCreate a water supply connected to the system separator.
ÎTurn 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.
ÎPlug in the antifreeze plug control line.
ÎPress the F2 key to start the motor.
ÎThe antifreeze liquid is routed into the antifreeze tank with fresh water from the fresh water reservoir.
ÎRinse for about 2 minutes. Watch the antifreeze hose until no more antifreeze can be seen.
ÎPress the F3 key to shut off the motor. Wait for the motor to stop trailing.
ÎRemove the antifreeze hose between the high pressure outlet and the anti- freeze return.
