4.8.1.
Filling the secondary DHW circuit
Carefully degas the DHW tank and the distribution network in order
to eliminate noises and hammering caused by trapped air moving in
the pipes during draw-off.
1. Completely fill the DHW tank via the cold water inlet pipe, leaving
the hot water valve open.
Close this valve only when the flow is regular and there are no
noises or hammering in the pipes.
2. Then successively degas all the hot water pipes by opening the
corresponding valves.
These operations also make it possible to rinse and clean
the hot water pipes located at the DHW tank outlet.
CAUTION
Completely vent the appliance and the installation for
optimum running.
