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:

Service instructions for the

solar thermal system

2. Check the fittings on the heating

water and DHW sides for leaks and

retighten if required.

3. Check the function of the safety

valves according to manufacturer's

instructions.

Inspection and maintenance

DIN 1988 requires a visual inspection

and (if required) cleaning no later than
