Calibration
• High limit temperature thermostat (fig. 5-2): it is
assembled inside the electrical heater element and it
acts as:
1. adjustable thermostat: it cuts off the electrical
supply to the heater element as the pre-set
temperature is achieved (the temperature can be set
between 0°C and 70°C, according to the user's
needs).
2. safety thermostat: it cuts off the electrical supply to
the heater element when, in case of bad operation of
the appliance, the temperature of the water reaches
90°C. A manual intervention is needed to start up
the appliance again (manual reset).

7. INSTALLATION INSTRUCTIONS
• Installation should be carried out, in accordance with
the regulation in force, by a qualified person who can
do, not only a proper set up of the appliance, but also
the necessary tests before starting the water heater.
• During
the original
maintenance, follow the instructions provided in this
booklet carefully. Modifications
connection or the non-observance of the provided
instructions will cause the warranty to be invalidated.
• Before installation, maintenance or repair, cut off the
electrical supply to the appliance.
8. LOCATION AND MOUNTING
Four fixing holes are present on the plastic case (fig. 8-1).
In this way an easy but firm and safe installation is
assured.
It's recommended to use metallic washer below the fixing
nuts.
The appliance can be installed in every position, provided
that it is located in such a way that the heat exchanger
and/or the electrical heater element are placed at the
bottom.
• Location: the appliance can be installed in every
position (provided that it is located in such a way that
the heat exchanger and/or the electrical heater element
are placed at the bottom) and in any space, with no

WATER'S QUALITY: to extend the working life of the
appliance water should be according the following
parameters, as foreseen by the European Directive
98/83/CE (on the quality of water intended for human
consumption):
 overall water hardness: included between 15 and 50
°F (in particular where water has undergone a
softening or desalisation treatment)
 chlorides : included between 25 and 100 mg/l)
 PH: included between 6,5 and 9,5
 conductibility: included between 400 and 1500 µS/cm

9. WATER CONNECTIONS (fig. 9-1)
Minimum water inlet pressure: 0,7 bar.
Connect the appliance according to the following
diagrams:
1. cold water inlet (1/2" NPT)
of
2. hot water outlet (1/2" NPT)
3. Engine cooling water out (1/2" NPT)
4. Engine cooling water in (1/2" NPT)
We advise that hot water pipes are insulated to avoid
useless waste of energy.
Fitting the pressure relief and non-return valve: a
pressure relief and non return valve is supplied with the
heater. The valve is included in the box separate from the
heater. The valve must be fitted to the cold water inlet
while installing the heater. It is necessary to remove the
protection cap of the heater element to install the valve
(fig. 9.2 e fig. 9.3).
WARNING: Do not replace the pressure
relief and non-return valve supplied with
the appliance with a non-return valve
(clapet).
