Post-adjustment, venting
Air is initially released from the hot water and venting
may be necessary. If gurgling sounds can be heard from
the climate system, the entire system will require addi-
tional venting. The installation is vented via vent valves
(QM20), (QM22) and other climate systems through
their relevant vent valves. When venting, VVM 325
must be off.
