DESCALING (STEAM / STEAM PLUS MODELS)
We recommend descaling the system every time you notice a reduction in the steam jet.
Use Hydroscale regularly as directed. For periodic descaling, use Hydroscale undiluted
and follow the steps below.
1)
Place the appliance either on top of waterproof fabric or over a collection tank (the
descaling product could damage the floors).
2)
Fill the tank with undiluted Hydroscale
3)
Turn on the switches to activate the steam function, without starting the brushes.
4)
Wait until the solution has completely finished.
5)
Turn off the steam function using the appropriate switches.
6)
Rinse the tank and fill it with water.
7)
Turn the steam function on using the appropriate switches.
8)
Let the steam escape for about 10 minutes (the time necessary for washing and
rinsing the nozzles).
At the end of this operation all the lime scale will be eliminated, together with all traces
of the descaling product.
The perforated dispenser 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.
7.6
CLEANING AND REPLACING THE FILTER (STEAM / STEAM
PLUS MODELS) REPLACE EVERY 12 MONTHS
A resin filter located inside the tank softens the water in order to reduce any lime scale.
CAUTION
Is advisable to replace the filter at least once a year.
