Filling the DHW cylinder
1. Fill the DHW cylinder from the DHW
side.
Note
Initially fill the cylinder from the DHW
side, then from the heating water
side. If the DHW side of your cylinder
cannot be filled yet, but you want to
commission your heating system,
then you can operate your cylinder
with a pressure of 2.5 bar on the heat-
ing water side.
Operation without DHW heating:
Operating instructions for the
heating system
Note
The ventilation of the solar coils
occurs via the solar flow. Collect
excess solar medium with a flexible
hose above the air vent plug and
restart the system.
Alternatively:
