A step-by-step guide to learning how to use the machine
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 BACKWA-
TER 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 opera-
ting 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 ACCESSO-
RIES
Attach the steam/suction handle (22) 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 -
am 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 squee-
zed.
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 acou-
stic 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 de-
creases. 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.
14
buttons regulate the amount of steam. The ste-
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.
"DETERGENT" FUNCTION USE
This function is very effective for removing any type of greasy filth.
Pour the desired amount of the product into the detergent bottle
(21). Adjust the amount of the product depending on the entity of
the filth to be cleaned. It is recommended not to exceed the indi-
cation of 20% placed at the side of the bottle. Pour water into the
bottle until it is full. Screw the cap on.
Position the bottle inserting the rear hook into the appropriate hole
at the side of the appliance. Lift the cover of the detergent connec-
tor (N) on the appliance and insert the connector of the bottle. To
disconnect the appliance connector, pull the 2 side buttons up. Press
the Detergent button (16). The function is now enabled.
Pulling the trigger, the detergent in the bottle (21) will come out
from the handle together with the steam. When the "Detergent"
function is active, the "Hot water" function and the iron (optional)
cannot be used. During use, the appliance automatically detects
when detergent runs out. In this case, the "Detergent" (16) button
will flash intermittently and the motor and steam-spray are disa-
bled. To continue to use the appliance, the bottle must be refilled
and the "Detergent" button (16) must be pressed again.
IMPORTANT: only use original detergent. Other products could da-
mage the appliance parts. Read the instructions on the bottle for
use of the detergent.
"HOT WATER" FUNCTION USE
This function is very effective to remove especially resistant filth
and to rinse the filth previously dissolved with the steam. Press the
"Hot water" button (17). The function is now enabled.
Pulling the trigger, high temperature hot water will come out of the
handle together with steam. When the "Hot water" function is acti-
ve, the "Detergent" function and the iron (optional) cannot be used.
"DISINFECTANT" FUNCTION USE
The steam jet of 909DW can be used on surfaces to distribute a
concentration of hydrogen peroxide suitable to sanitize them from
viruses and bacteria.
The oxidizing action of peroxide extends the natural sanitization
properties of steam to all surfaces that cannot be reached by a di-
rect and prolonged jet of steam.
Turn on the appliance as indicated in the Step 3, then press the
boiler switch (12).
Connect the nozzle to the steam hand piece (22).
Insert into the cleaning bottle (21) the 10-volume hydrogen peroxide
solution (3%). Press the clean button (16). The sanitizer dosing fun-
ction is now enabled. Wait for the appliance to reach the operating
pressure (steam light indicator ready (18) on).
Apply the jet of steam to the surfaces and objects you want to sani-
tize, by pulling the trigger on the hand piece.
Leave the product on the surfaces until completely dried.
Do not use the sanitizer with other accessory (extension tubes,
brushes, etc.)
