If the existing drain is located above the specified level an adequate drainage pump must be installed
(optional).
Do not install the outlet hose in tubs, sinks etc.
8. CONNECTING THE ELECTRICAL SUPPLY
1) The units are delivered ready for working with the voltage shown on the data plate.
2) Connect to the electricity line, interposing a suitably rated automatic circuit breaker, where the opening
distance between the contacts must be at least 3 mm. Furthermore, supply voltage must not deviate
from the voltage value by +5% to -10 %.
3) The characteristics of the flexible cable chosen for connection to the electricity line must not be inferior to
the type with rubber insulation H05RN-F and it must have a nominal cross section suitable to absorb
maximum current; hence, as indicated in the table, it must have the same minimum cross section
indicated relative to the model.
4) To access the power inlet terminal board and replace the power cord, check the positioning in the
attached installation diagrams.
N.B. It is essential that the appliance is connected to an efficient earth plug. For this purpose, near the
connection terminal board there is a terminal marked with a plate with the
symbol on it and to
which the earth wire must be connected (yellow-green).
ATTENTION: The use of adaptors, multiple sockets or extension cables is strictly forbidden.
Check and tighten all the screws of the electric system which may have become loose during
storage or transport.
ATTENTION: Safety device installed; The appliances are equipped with a manual reset safety device
which, in the event of an increase in temperature beyond the predefined maximum limit, cuts in, thus
interrupting the power supply to the heating elements.
The event is signalled by the switching off of the light during normal operation.
9. EQUIPOTENTIAL CONNECTION
If several appliances are installed in a row, the appliance must be connected to an equipotential system
whose effectiveness must be verified in accordance with the relative current laws. The connection is at the
back of the appliances and marked with the “EQUIPOTENTIAL” plate.
NOTA:
the manufacturers decline all responsibility if the accident prevention rules described above are not
complied with!
10. ADJUSTMENTS AND CHECKS
The temperature inside the bowl is set at 55/60°C.
This temperature favours the correct use of the chemical characteristics of all industrial detergents.
It is advisable not to change this parameter.
The temperature of the boiler is set at 87-90°C.
This value allows the rinse water temperature to be optimized throughout the cycle.
10.1
RINSE AID DISPENSER
The appliance is equipped with a fully automatic rinse aid dispenser.
Before starting the appliance make sure that the rinse aid suction tublet is inserted to its container.
During the manufacturing process the dispenser is calibrated for maximum opening and must be then
adjusted according to the water hardness.
