ELECTRICAL COMPONENTS (Heating Element - Thermostat)
THERMOSTAT AUTOMATIC
AUXILIARY THERMOELECTRIC FUSE
This is tripped when the water storage
tank’s internal temperature exceeds
115°C and shuts down the thermostat, to
protect the appliance form overheating.
RESETTING THE
THERMOELECTRIC FUSE
Rotate the temperature regulator until
the button of the thermoelectric fuse
appears and press it. Once the fuse has
been reset to its normal operating
position (pressed in), the thermostat can
operate again.
For the system’s optimum operation using natural circulation, the
maximum and minimum distances and angles for the pipes must
be respected. The maximum distance between the collector
outlet and the water storage tank inlet must not exceed 3m. The
angle of the pipe joining these 2 points must not be less than 8°.
SYSTEM INSTALLATION ON A TILED ROOF WITH THE WATER STORAGE
TANK UNDER THE ROOF (Natural circulation operation)
This concerns triple action solar systems equipped with a large exchange surface coil, for the alternative heating of
the water using the central heating system. The coil is placed in front of the electric parts.
HYDRAULIC CONNECTION
The central heating system to which the solar system is to be connected must be equipped with:
•
Solar system isolation valves.
•
Automatic relief valves at the highest point of the pipes, which must be very well insulated.
•
Suitably angled connecting pipes so as not to trap air in the circuit.
•
The connections to the coil heat exchanger must be made through unions.
