Commissioning [specialist]
Attention: risk of burns and scalding!
The valves and fittings can heat to temperatures of more than 100 °C due
to the solar fluid. Therefore, do not clean or fill the system with the
collectors heated (intense sunshine).
Please note that hot solar fluid can leak from the pressure relief valves in
case of too high system pressure!
Attention: risk of frost!
If you flush with water, make sure that the installation is completely
drained before filling with solar fluid.
Use the solar fluid Tyfocor L, a mixture of propylene glycol and water with
45% of propylene glycol.
Note regarding the commissioning sequence
When putting the system into operation, first fill the heating circuit and
then the solar circuit. This guarantees that heat that may possibly be
absorbed by the collectors during commissioning can be dissipated.
Note regarding the expansion tank
Close the shut-off valve of the expansion tank during flushing and filling to
prevent that dirt particles are washed from the solar installation into the
expansion tank.
