Connect the equipment according to the following (FIG_8-1):
1. cold water inlet (1/2 ")
2. hot water outlet (1/2 ")
3. discharge water from the cooling circuit of the motor (1/2 ")
4. return water to the cooling circuit of the motor (1/2 ")
Minimum pressure inlet: 70 kpa.
Insulate hot water pipes: this will avoid wasting energy.
Installation of the pressure relief and non-return valve: the valve is factory supplied with the appliance but it is not installed.
Therefore it is necessary to fit it to the cold water inlet when installing the appliance. (S-- FIG_8-1 ).
WARNING: DO NOT REPLACE THE SAFETY AND NON-RETURN VALVE SUPPLIED WITH THE
UNIT WITH A SIMPLE NON-RETURN VALVE.
WARNING: CONNECT THE DRAIN OF THE VALVE TO A RUBBER HOSE HAVING AN
INTERNAL DIAMETER OF 9.5 MM. THIS DRAIN HOSE HAS TO BE INSTALLED WITH A
CONSTANT DOWNWARD SLOPE AND PROTECTED AGAINST ICE.
9. WIRING
The unit must be connected to a single-phase power supply (please be sure to connect the correct voltage: 120 V or 230 V
according to the data label on the unit) and to an efficient ground wire.
THE MANUFACTURER DENIES ANY RESPONSIBILITY FOR DAMAGES OR INJURIES RESULTING
FROM THE FAILURE TO EARTH THE APPLIANCE
The unit is supplied with a power cable with Schuko plug. Connect the power cable in accordance with the wiring rules in
force in the country where the appliance is installed. When replacing the power cable, use only a cable with the same
characteristics (H05 VV-F - 3x1, 5 mmq). In the event that the Schuko plug is not needed, cut the power cable and connect it
into a different plug or directly to the power connection. Please be sure to connect the polarity correctly (FIG_9-1):
• L -> phase (brown wire)
• N -> neutral (blue wire)
Foresee a two-way switch next to the appliance to allow the isolation of the appliance.
WARNING: BEFORE WORKING ON THE THERMOSTAT, MAKE SURE THE POWER IS COMPLETELY
DISCONNECTED.
10. INSTRUCTIONS FOR USE
The electrical heating element is equipped with a thermostat that has the following two functions:
1. Adjustable thermostat (T - FIG_9-1), cutting off the power to the electrical heating element when the set temperature
is reached (the temperature can be adjusted between 0 ° C and 65 ° C, according to the user's needs).
2. Safety thermostat, cutting off the power to the electrical heating element when the temperature of the water reaches
90 ° C. A manual intervention is necessary to restart the appliance (manual reset). In this case, follow these steps:
a) disconnect the power supply
b) remove the protection cap of the heating element
c) press the reset button located on the thermostat (R - FIG_9-1)
d) replace the protective cover
e) restore power
WARNING: CONNECT POWER TO THE ELECTRICAL HEATING ELEMENT ONLY WHEN THE TANK IS
FULL OF WATER. THE HEATING ELEMENT IS NOT SUITABLE FOR DRY OPERATION
11. MAINTENANCE
To make the safe operation of the equipment and to extend its working life, a periodic inspection by an authorized service is
recommended at least once a year. The enameled models (models BB20 ..) are equipped with a sacrificial magnesium anode
to prevent corrosion of the tank: the anode has to be replaced at least once a year, otherwise the right to the warranty will be
lost (FIG_11-1)
