ELECTRICAL CONNECTION

DESCRIPTION OF ELECTRICAL COMPONENTS (heating element - thermostat - accessories)
ELECTRICAL DIAGRAM - General rules
The electrical installation of the solar water heater should be carried out by a qualified electrician and in accordance
with the national regulations in force and the rules and conditions that apply to the building where the installation is
taking place.
The heating element must not be switched on when there is no water in the water storage tank.
In such case the heating element warranty does not apply.

NOTE: The heating element's rating depends on local regulations of the country of destination.
1. Remove the screws from the protection flap which covers the electrical components (Image B1).
2. A 3x4mm² section electrical cable (for a 4kW heating element) is required to connect the heating element to
the mains (Image B2).
3. Pass the end of the cable through the gland and towards the electrical components.
4. Connect the black wire (phase) to the connector L and the blue wire (neutral) to the connector N on the
thermostat. Connect the yellow wire (earthing) to the small M4 screw on the heating element marked with the
ground symbol (Image B3).
5.
The thermostat has been connected to the heating element at the factory. Adjust the thermostat to 60°C.
Attention!
The thermostat should be well fitted at the heating element (Drawing 1)
6. Close the cover of the electrical components (Image B4).
7. Switch off the central mains switch.
8. Connect the other end of the cable to the electrical board using a bipolar disconnection switch with a minimum
distance between contacts of at least 3mm. The circuit breaker's rating must be suitable for the heating
element in use.
Caution!
A safety relay against electrical shock is absolutely necessary.
NOTE: The daily hot water (40°C) load which can be met by the system without any contribution from solar energy
(that is, only through 24h 2kW heating element operation), according to 5.10 of EN 12976-2:2000, is this of maximum
1000lt.
