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.
Using  a  liquid-suction  machine,  hook  the

“TANK

SUCTION” accessory into its 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
complete  the  load).  When  the  pump  has  finished
loading  the  boiler  and  stops,  immediately  switch  off
the  main  switch,  unplug  it  and  leave  the  machine  at
rest for 6-7 hours.
(Att:  do  not  leave  the  solution  after  the  indicated
times).
4- With  the  machine  cold  and  the  plug  disconnected,
shake  it  well  and  then  open  the  cap  under  the  boiler
(15), now empty well all the limestone dissolved in the
solution.
Now clean and close the drain plug carefully.
5- Fill the charging tank (7) with clean water. Turn the
machine  on  and  wait  for  the  boiler  to  be  charged
again and following the instruction written in “Start to
use”.  Wait for the charging and the heating.
Now, for about 10 minutes the steam supply will smell
of lemon given by the washing performed.

► * after the cleaning operations of the boiler, it is
advisable to check if the caps under the machine leak,
in this case check their closure with a wrench or (with
the machine discharge and cold) replace the seal with
an original spare part.

PROBLEMS AND SOLUTIONS

FAULT
Steam leaks from the accessories

SOLUTION (End user)
due to wear or damage of o-rings. Replace them taking
care not to damage them and insert them with attention.
Lubricate them with grease (no mineral).

FAULT
Steam tube plug is difficult to insert into the outlet of the
machine

SOLUTION (End user)
Do not force to insert it, but put a bit of silicone lubricant
on the o-rings and into the joint connection .

FAULT
The boiler needs much time to warm up.

SOLUTION (End user)
Clean the boiler as described. In case, make the
absorption with the power rating indicated in the
technical data check.

FAULT
Pressure drops quickly while using the steam

SOLUTION (End user)
Clean the boiler as described. In case, make qualified
personnel check the correct working pressure and the
integrity of the resistance.
FAULT
Intervention of the circuit breaker during use.
(Probable dispersion from the resistance or electric
valve to ground)
SOLUTION (Qualified personnel)
Check that the power cord is not visibly damaged (if so,
substitute it).
Try connecting the plug into a different socket.
Verify that there are no spills or leakage of water from
the machine that are deposited in the electrical parts.

FAULT
Steam gets out of the exhaust valve in the bottom of the
machine.
SOLUTION (Qualified personnel)
Check the correct working pressure of the boiler, check
the functioning of the level probe and in case replace
the safety valve with an original spare part, of identical
characteristics.
FAULT
Vacuum does not work (engine does not start).
(probable intervention with interruption of the fuse to
protect the socket, for excess absorption or failure of
the motor)
SOLUTION (Qualified personnel)
After checking the lack of power in the intake of the
vacuum with the vacuum control active, remove the
power plug, open the machine and replace the fuse (8A
250V Timed). Before connecting it again, check that the
motor is not shorted or has electrical problems.
