ART. S001-S002-S003-S004 SOLAR MODULE
START-UP
1. Connect an external pump to the tap 3 of the instrument holder connection 2 (Tab.1). The pump is used to increase the
pressure in the system.
2. Start the pump, open the tap 3 and increase the pressure in the system up to the maximum value. Read the pressure value
on the manometer 2 (Tab. 1), then close the tap 3 and stop the pump.
3. Open the shut off valves 4 (Tab.1) and 7 (when present) by turning them counter-clockwise until they stop.
4. Fully open the flowmeter 6 (Tab. 1) carrying the reference mark of the flowmeter in vertical position (see operating
specifications on page 10). Check that the drain cock 3 is closed.
5. Start the circulator 5 (Tab.1).
6. Let the system running for a while, check the hydraulic seals of the system.
7. Open both the shut off valves 4 (Fig.1) and let drain any remaining air in the system, then close the valves.
8. Stop the circulator 5 (Tab.1)
9. Restore the pressure to the desired operating value as described above in step 2.
10.The system flow can be regulated by using the flowmeter 6 (Tab. 1) and reading the flow value on the scale "flow
indicator" (see operating specifications on page 10). During this operation, the circulator 5 has to run at its maximum
power. To choose the flow rate suitable to the system follow the instructions of the solar panels manufacturer.
11.After a few hours of operation, remove air from the solar system once again with the air vent valves A (Fig.1) and the
deaerator 8 (Tab. 1) when present. After all air has been removed, check once again the pressure in the system with the
manometer 2 (Tab.1) and, if necessary, restore the desired operating value as described above in step 2.
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 shut off valves connected with the air vent valves A (Fig.1).
2. Open both the shut off valves 4 (Tab.1) and 7 (when present) turning their handles to 45° (see the operating specifications
of these valves on page 11 of this data sheet)
3. Open the drain cock of the flowmeter 6 (Tab. 1) or the tap located at the lowest point in the system.
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 4).
2. Define the positioning of the module on the wall and mark the position of the 4 holes for the fixing (G).
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.
