START-UP
1.
Close the filling/emptying tap on the flow controller (6 in Tab.1) and increase the system’s pressure up to the maximum
permitted value. Close the tap when this value is reached.
2.
Open the valve on the on/off assembly (4, 7 in Tab.1) and operate the pump (5 in Tab.1).
3.
Leave it to circulate for a certain amount of time, and then check the hydraulic seals in the system.
4.
Open the air bleed valves A (Fig.1) again, removing air from the system again by turning on the circulation pump briefly.
5.
Restore the desired air pressure.
6.
The rate of flow of the system may be modified using the flow controller (6 in Tab.1), working the ball valve above the
graduated scale (refer to flow meter description). In order to do this the pump must be set to maximum power. Follow the
solar panel manufacturer's instructions to adjust or limit the rate of flow.
7.
After a few hours of operation, remove air from the solar energy system again at the highest point in the system A (Fig.1)
and in the air separator (8 in Tab.1). When you have finished bleeding air, check the pressure in the system and restore the
desired operating pressure if necessary.
EMPTYING THE SYSTEM
The system must be emptied if it has been filled with water only and will be exposed to a risk of freezing.
1.
Open the on/off and check valves by turning the thermometer holder to 45° (4, 7 in Tab.1).
2.
Open the air bleed devices at the highest point A (Fig.1).
3.
Open the emptying tap at the lowest point in the system (3 in Tab.1).
INSTALLATION AND WALL MOUNTING
The fixing of the delivery part (A) and return part (B) to the insulation shell (C) is made in the factory by two screws M8x35mm
and two washers (D).
The supporting plate (E) and the dowels for the wall fixing (F) are optional.
To install the solar module please proceed as follows:
1.
Lay the pipes inside the solar system, leaving enough space for the solar module as shown in Table N.2 (page 2).
2.
Define the positioning of the module on the wall and mark the position of the 4 holes for the fixing (F).
3.
Drill the wall and insert the dowels (dowels are not included).
4.
Fix the solar module to the wall and connect it to the system pipes.
5.
Check that all unions are properly tight.
6.
Proceed with the electrical wiring.
