Filling the DHW cylinder
1. Fill the DHW cylinder from the DHW
side.
Note
If the DHW cylinder is pressurised,
re-torque the flange cover with a tor-
que of 40 Nm.
The cylinder cap does not need to be
tightened.
2. Check the fittings on the heating
water and DHW side for leaks and
tighten if required.
3. Check sensor wells for leaks and
retighten, if required.
4. Check the function of the safety
valves according to manufacturer's
