MAINTENANCE.
ATTENTION. BURNING DANGER
The boiler cleaning must be carried out when the equipment has cooled down (i.e. switched off for
at least 5 hours) - for this reason we suggest to maintain the boiler in occasion of the following
use, as long as at least 5 hours have passed. Please proceed as follows:
The device is equipped with a maintenance warning system, which every 30 effective working hours
displays the advice
“C A L C” to warn the user to proceed with the boiler cleaning.
When this warning appears on the display it is still possible to use the unit until the end of the cleaning
process; then, it will be necessary to switch the unit off by using the main switch (8) and unplugging the
power cable (26). The boiler cleaning must be carried out when the equipment has cooled down (i.e.
switched off for at least 5 hours) - for this reason we suggest to maintain the boiler in occasion of
the following use, as long as at least 5 hours have passed. Please proceed as follows:
Place a recipient under the machine, remove the boiler drain cap (28) and wait until the boiler is
completely emptied.
Clean eventual residuals from the cap with running water, check the efficiency of the gasket located on the
bottom of the cap and, if necessary, substitute it (please contact your supplier for the spare parts); close
the drain cap again.
Using water with hardness higher than 10 French degrees, (according to the usage of the unit, > 2 hours
/ day) it is necessary to use water treated with a proper water softener system, which can reduce the
calcium carbonate up to less than 4 French degrees, increasing by consequence the liability of the
steam generator. (for any further details or to buy a water softener system, contact your supplier).
The cleaning of the boiler is completed, insert the power cable (26) into a suitable plug and activate the
main switch (8), the “Power / Stand-by” switch (10) and the “Boiler” switch (12). It is recommended to
activate also the minimum steam switch (36) on the handgrip, pressing also the safety switch (36A) to
allow the outlet of the air remained in the empty boiler. Wait until the refilling system has finished
(approx. 2 minutes).
The maintenance of the boiler is completed; proceed with the using instructions as described in the
paragraph (f) of the chapter 7.
We suggest to empty the water tank (20) completely if the machine will not be used for a long period of
time.
