Use linen- rubber tubes for water connection, arranged for 15 Bar pressures, interposing a valve or a faucet [17] ABOVE
the delivery pipe; use a 3/4" rubber holder [18], well fixed with a proper band [19] to connect the tubes at the device’s union.
Note: Tubes for the water feeding of households are on the market (ex. dishwashers) which, in addition to being
cheap, feature the requested characteristics and are predisposed with a rubber holder.
The unions are placed on the back panel of the device, they are marked by a plate “H
2
O” [20] and are labelled with:
IN: INLET of fresh water in the device;
OUT: OUTLET of water used by the device.
Follow the following precautions to avoid damages at the device’s water circuit:
- do not invert the connection of tubes;
- if water in the area presents a high quantity of spur, install a suitable decalcification or filtration device above
the delivery pipe;
- if not otherwise mentioned in the Technical Handbook, the incoming water’s pressure must be compre-
hended between 1.5 and 6 Bar (ideal pressure: 3 Bar). If the pressure in the device is higher, it is necessary to
interpose a pressure limiting device, appropriately regulated, above the delivery pipe.
AVOID CONSTRICTION OR NARROW TURNS OF THE TUBES.
Note: The water outcoming the condenser, though being hot and not drinkable, is not polluted and can be reutilised.
Before storing the device in rooms with a temperature lower than 0°C it is INDISPENSABLE to get rid of
the water in the condenser and in the inlet and outlet pipes. Call the Assistance Service.
5.5 Initial functioning checking
At the end of the installation, and before utilising the device, it is indispensable to let a qualified techni-
cian checking the correct connection, by performing the following procedure.
- Before starting, check that the socket's breaker is in the position “0”;
- Insert the plug in the socket, and put the general Breaker in position “1”;
- only the green indicator on the ON/OFF Pushbutton [Z1] on the control panel must turn on;
- close the cover and press the ON/OFF Pushbutton [K1]. The device predisposes itself for functioning and the display
shows the total time previously set (in prime minutes);
Remove the beater from the cylinder before carrying on the checking, to avoid letting it function dry.
ATTENTION: Follow the directions reported on Par. 7.2 - Disassembly of parts.
