Note:
It is recommended to use a hose that is
equipped with an Aquastop coupling on the

ing system and open the water supply
(max. 60 °C, max. 5 bars).

tem will interrupt the water supply when
the tank is full.

nect the hose from the appliance.
Detergent is added to the fresh water on
the way to the cleaning head with the help
of a dosaging device.
Note:
The dosing unit can be used to add 3% de-
tergent at maximum. With higher dosage
the detergent must be put into the fresh wa-
ter tank.

Place the canister with the detergent in
the trough behind the seat.
 Unscrew the canister lid.
 Insert the suction hose of the dosing
equipment into the canister.
