Commissioning procedure
26/04/2016 - 7607575-05
WARNING
Initial commissioning must be done by a qualified
4
professional.
During the heating process, water can flow through
4
the bleed circuit to guarantee the safety of the
installation. This phenomenon is perfectly normal
and must in no circumstances be hindered.
5.3.1.
Secondary circuit (domestic water)
Set the domestic hot water thermostatic mixing valve to the required
temperature to avoid scalding when running domestic hot water.
WARNING
The thermostatic mixing valve must be set to maximum at
60°C.
5.3.2.
Primary solar circuit
1. Inspect all the connections in the system for leaks.
2. Leave the fluid circulating round the system for some time and
check again for leaks - (regulator in manual mode).
3. Open the vent valve of the manual bleed degasser (bleed again).
4. Bring the pressure in the system up to the 2 bar (0.2 MPa) working
pressure by topping up if necessary with heat transfer fluid.
5. After several hours of operation, the system should be bled again
(via the manual bleed degasser). After bleeding, check the system
pressure and add more fluid if necessary.
6. Check that the control system is in automatic mode.
7. Check the anti-thermosiphon valves.
8. Check the connection of the solar pump.
9. Check the position of the solar hot water tank sensor.
10.Complete the "Commissioning protocol" sheet at the end of the
notice.
n Starting and stopping the control system
CAUTION
If the temperature in the solar collectors is higher than
130°C, the control system operates in safety mode. Wait
until the evening before start-up or cool down (cover) the
solar collectors.
The installation is switched on.
