6.3 Flushing and filling the solar circuit (connections primary)
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. Please observe the separate
instructions regarding the expansion tank!
2. Connect the flush and fill station:
- Pressure hose to the drain valve [G], f. ex. of the left module
- Flush hose to the fill and drain valve [L] at the ball valve [K1], f. ex. of the right module
Note: Connect the pressure hose and the flush hose to different modules,
in order to assure a correct flushing and filling!
3. Open the flow and return ball valves [B1|B2] and [K1|K2] on both stations.
4. Put the check valves [J1|J2] out of operation on both stations (position 180°, see page 26).
5. Open the fill and drain valves [G|L] and put the flush and fill station into operation.
6. Vent both stations first at the T-piece [D] and then at the Airstop [F] until the solar fluid
exits.
7. As soon as the solar fluid exists without bubbles from the fill and drain valve [M], close the
return ball valves [K1|K2] of both stations.
