The fittings can heat up to more than 100 °C. Therefore, it is not allowed to flush or fill the system if the collectors are hot (intense solar radiation). -
Page 13: Flushing And Filling The Secondary Circuit
4 Commissioning [specialist] Flushing and filling the secondary circuit NOTICE Note regarding the expansion tank To prevent that dirt particles of the solar system are washed into the expansion tank, some manufacturers recommend to disconnect the expansion tank from the solar circuit during flushing and filling. -
Page 14: Flushing And Filling The Solar Circuit
4 Commissioning [specialist] Flushing and filling the solar circuit The valves and fittings required to flush and fill the station are integrated in the transfer station. Make sure not to wash dirt particles into the heat exchanger and the expansion tank. Therefore, only use flush and fill stations with fine filters. - Page 15 4 Commissioning [specialist] Airstop The Airstop with manual vent valve is used to vent the solar installation. To ensure a perfect venting of the solar circuit, the flow velocity in the flow line must be at least 0.3 m/s. Pipe diameter [mm] Flow rate at 0.3 m/s ∅...
- Page 16 4 Commissioning [specialist] 1. Disconnect the expansion tank from the solar installation. This avoids that dirt particles still present in the pipes are washed into the expansion tank. 2. Put the check valve out of operation by turning the ball valve [a] into position 45° (see page 14).
- Page 17 4 Commissioning [specialist] 11. Reduce the pressure on the drain valve [d] to the operating pressure. 12. Connect the expansion tank to the solar circuit and set the operating pressure of the solar system by means of the flush and fill station (see instructions regarding the expansion tank).
- Page 18 4 Commissioning [specialist] 18. Remove the hoses of the flush and fill station and screw the sealing caps onto the fill and drain valves. The sealing caps only serve to protect the valves against dirt. They are not designed to take up high system pressures.
