TANK SUCTION ACCESSORY

Accessory to be connected to
the flexible hose to vacuum
and clean the tanks.

MICROFIBER CLOTH

Cloth to be used hooked with the
multi-purpose brush to clean
delicate surfaces, such as wooden
floors, furniture, etc. It offers a
great absorption power, reduces
the power of the steam dispensed
and reduces the friction of the
brush during the treatment

BRUSHES

These brushes must be
connected to the STEAM
LANCE. They are used to
remove resistant dirt and for
deep cleaning, even in the
corners or small spaces.
Choose the most suitable type
(ø28, 40, 60 mm) according to
the surface to be treated.

MANTAINANCE

(End user)

* Always remove the plug before cleaning
or carrying out operations on the machine.
* End user must not open or dismantle the
machine

For the safety of the operator and to always ensure a
perfect performance, we recommend the following
checks and maintenance:

AFTER EVERY USE:

For a correct cleaning, it is advice to clean the machine
and  its  accessories  with  a  clean  cloth  moistened  only
with  a  few  drops  of  water.  Do  not  use  alcohol  or  other
solvents,  they  may  damage  the  plastics  and
components.
To  maintain  efficient  and  easy  to  couple  the
accessories,  check  the  o-ring  seal  (

steam sealing

gaskets

) and possibly wet them with a little silicone

grease.
VACUUM FUNCTION: when you finish to vacuum, it is
advisable to vacuum some water to clean the conducts
and the filter. Afterwards, dry the bucket or do not totally
close it so that it will dry itself.

PERIODICALLY:

Periodically check that the power cord does not show
signs of wear or aging. If it is damaged, it is absolutely
necessary to get it replaced by specialized personnel
before being able to re-use the appliance again.

BOILER CLEANING

(End user)

Once a year a check and boiler cleaning must be
carried out in our authorized centers.

RINSE

: It’s recommended at least every 50 hours of

operation or 2 months.
a) DISCHARGE: The machine must be cold or definitely
discharged  from  the  steam  pressure  and  the  plug
disconnected  (see  pressure  gauge  (4a)).  It  is  possible
to use the Boiler-Off switch (6) to completely discharge
the  steam  from  the  boiler:  With  the  machine  switched
on, turn off the Boiler-Off switch (6), insert the hose into
the  machine's  socket  (5)  and  pressing  the  button  (10)
completely dispense all the residual steam in the boiler.
(keep the dispensing active for a further minute after the
apparent  steam  escapes  to  ensure  that  the  boiler  has
been  completely  emptied)  (see  pressure  gauge  (4a)).
With the help of a wrench CH 21 unscrew the cap (15)
placed  under  the  machine  in  correspondence  of  the
boiler (see image). After having taken off the cap, shake
slightly  the  machine  to  let  the  water  and  the  dissolved
limestone out.
When the boiler is empty, clean and close carefully the
cap tightening it with the wrench.
b) FILLING: Fill the water tank (7), turn the machine on
and  make  it  start  again,  waiting  for  the  boiler  to  be  re-
charged again.
(

att

: it may be that during the first charge cycle, the

“end of water” light turns on and you need to shut
down/restart the machine to complete the load)

BOILER AND TANK CLEANING:

The  boiler  cleaning  is  recommended  at  least  every
200 hours of operation or 6 months.
1- Cleaning with suction of the plastic tank (7): Check
that  the  water  level  in  the  plastic  water  tank  (7)  is  at
least  halfway  up,  shake/move  the  machine  to  shake
the water and any possible deposit.
Connect the flexible hose to the connector block (5) of
the  machine,  and  hook  the

“TANK SUCTION”

accessory into the handle, insert the accessory tube
into the tank (7) and completely suck the water in it.

(Operation also possible in the tank (8))

2- The machine must be cold or definitely discharged
from the steam pressure and the plug disconnected.
Exhaust  the  contents  of  the  boiler,  carefully  following
what  described  in  the  previous  point  "BOILER
DISCHARGE".
Prepare  2  liters  of  water    and  vinegar,  in  proportions
of about 60% vinegar 40% water.
Insert  the  prepared  liquid  in  the  refill  tank  of  the
machine (7).
3- Turn  on  the  machine,  check  that  the  Boiler-Off
Switch  (6)  is  in  the  Off  position,  wait  until  the  pump
finishes filling the boiler. (att: it may be that during the
first  charge  cycle,  the  water  end  indicator  lights  up
and  the  machine  must  be  switched  off  /  on  again  to
