INSTALLATION
MAX TEMPERATURE OF RETURN WATER FROM THE ENGINE COOLING CIRCUIT : 65 °C
It is recommended to insulate the hot water pipes in order to avoid unnecessary waste of energy.
The device is equipped with combined temperature and pressure relief valve (calibration: 700 kpa / 99°C) : it protects the tank
from possible excessive pressures caused by the expansion of water during heating.
Upon the occurrence of this situation, the water is discharged through the outlet of which is equipped with the valve (S -
FIG_8-1). Caution: connect the water drain valve to a rubber tube
PIPE CONNECTED TO DISCHARGE VALVE MUST NOT BE SEALED OR LOCKED, MUST BE
INSTALLED WITH A CONSTANT INCLINE DOWN AND PROTECTED BY ICE.
IT MUST NOT BE CONNECTED TO A TAP AND MUST BE KEPT CONSTANTLY FREE OF
OBSTRUCTION
9. ELECTRICAL CONNECTIONS
The apparatus It must be connected to a single-phase power supply (please pay attention to connect the correct voltage
according to the data present on the label) and to an effective ground connection.
CAUTION: BEFORE MAKING THE CONNECTION, MAKE SURE THE POWER IS COMPLETELY
DISCONNECTED. THE BUILDER DOES NOT ACCEPT RESPONSIBILITY FOR POSSIBLE DAMAGE
CAUSED BY FAILURE OF THE APPLIANCE BE GROUNDED
The apparatus is equipped with a power cord with plug. Plug the power cord in accordance with the wiring regulations in force
in the country where the equipment is installed.
If the use of the safety plug it is not necessary it's possible to cut the power cord and connect it to a different plug or directly

Be careful in properly connect the polarities (FIG_9-1):
The electrical system a bipolar switch must be installed to turn on and off the device and a fuse of suitable rating. The
connections to the mains must be made in accordance with the national standards of electrical installations.
WARNING: CONNECT THE POWER TO THE ELECTRIC HEATER ONLY WHEN THE TANK IS FULL OF
WATER. THE HEATING ELEMENT IS NOT SUITABLE FOR OPERATION DRY
10.SETTING THE WATER TEMPERATURE
On the electrical resistance there is a thermostat, which interrupts the power supply when the preset temperature is reached.
Setting the temperature (T - FIG_09-1): it is possible to adjust the hot water temperature between 0 ° C and 60 ° C, according
to the user's needs. The thermostat regulates the water temperature in the operation exclusively with electrical resistance.
WARNING: BEFORE WORKING ON THE THERMOSTAT, MAKE SURE THE POWER IS COMPLETELY
DISCONNECTED
