STEP 1

FILL COLD TANK WITH WATER

With the appliance unplugged, fill the cold tank as indicated in point 9 (maximum 1.5 litres).

STEP 2

POURING FILTER WATER IN THE BACKWATER TANK

Open the tank cover (3).
Take out the tank (1) and the filter basket (2).
Pour water in up to the level (between Min and Max) indicated on the tank.
Do not activate the suction function if you have not first poured water into the backwater tank.
Do not exceed the indicated water level.

STEP 3

TURNING THE POWER ON

Remove the power cord from its compartment (7). Plug it into an electrical outlet.
Press the main on/off button (11). The indicator light goes on (13) indicating that the device is on.
Press the boiler on/off button (12). The indicator light goes on (14) indicating that the boiler is warming up. If
you turn on the boiler on/off button by itself, the machine will not be ready for use because the steam functions
are only activated when the main on/off button has been switched to on. When the “steam ready” indicator
light comes on (18), it means that the machine has reached its operating pressure. Once the indicator has been
turned on, the light will continue to go on and off throughout use. There is no need to pay attention to it.

STEP 4

ATTACHING THE HANDLE AND ACCESSORIES

Attach the steam/suction handle (21) to the socket (4). Attach the desired accessory to the handle.

STEP 5

REGULATE THE MOTOR POWER AND THE AMOUNT OF STEAM DEPENDING ON USE

The + and -

buttons are used to regulate suction power. To turn the motor off, press either one of the buttons for a

few seconds. The suction power is indicated by a red indicator light beneath the symbol: slow and intermittent = low
power, always on = maximum power.
The + and -

buttons regulate the amount of steam. The steam level is indicated by a green indicator light beneath

the symbol: slow and intermittent = little steam, always on = maximum. Press the trigger (B) to make steam come out.
The amount of steam and the suction power cannot be regulated while the trigger is squeezed.

STEP 6

CHANGING THE FILTER WATER

Periodically, throw away the dirty water and replace it with clean water. When the water in the backwater tank
is clean, it filters better. The tank is transparent so you can check whether the filter water is clean or dirty.

STEP 7

BOILER EMPTY

If the boiler empty indicator (19) turns on, accompanied by the acoustic signal, while the appliance is in use, fill the boiler
as indicated in step 1. It is not necessary to wait until the boiler pressure decreases. The cold tank located under the
funnel cap (9) is not under pressure and can be filled at any time. A pump transfers water from the cold tank to the boiler
when necessary.

USING THE SUCTION FUNCTION ALONE

The machine can be used as a water-filtered vacuum cleaner. In this case, you do not need to turn on the boiler.
