At the end of this operation all the lime scale will be eliminated, together with all traces of the
descaling product.
The perforated diffuser that squirts the steam towards the floor is made of special inert material
(Teflon) that ensures its cleanliness as it prevents lime scale from adhering to the surface.
HINTS ON THE “STEAM” GENERATOR OPERATION
The boiler starts heating up when the main switch (figure “1.16” ) on the steam generator is
turned on (red LED indicator light switched on).
The heating of the boiler is controlled by one thermostat which deactivates the operation in
case of a fault.
A thermofuse limiting device interrupts boiler operation in the event of thermostat malfunctions.
When the switch located on the handle (figure “1.17” ) is turned on, it activates the pump and
starts introducing the water into the boiler to generate steam.
The ‘empty’ operation of the pump in the absence of water in the tank, may cause it to overheat.
Once the overheating level reaches a critical level, a thermostat incorporated into the pump will
intervene and immediately block its operation allowing it to restore operation by means of cooling.
It is always recommended to turn off the pump using the main switch in case of no water in the
tank.
WARNING
Do NOT touch the steam spray nozzles or the metal panels of the machine
with your hands due to the high temperatures that they reach during
operation.
