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.
