Screw angle ball valves of the vibration decouplers
to the heating circuit connections.
Heating circuit outflow (forward
flow) connection
Heating circuit inflow (return
flow) connection for models
without cooling function.
Heating circuit inflow (return
flow) connection for models
with cooling function.
NOTICE.
Always note which is the inow (return ow)
and outow (forward ow) of the heating cir-
cuit. They are marked with colors, as are the
vibration decouplers:
red = hot water outow (forward ow)
blue = hot water inow (return ow)
Place a bleeder at the highest point of the heat
source in the heat source outflow.
If necessary, place a bleeder at the highest point of
the heat source in the heat source inflow.
Place a bleeder at the highest point of the hea-
ting circuit in the heating circuit outflow (forward
flow).
If necessary, place a bleeder at the highest point
of the heating circuit in the heating circuit inflow
(return flow).
We recommend installing a contamination filter
(screen size 0.9 mm) on the heat source inflow
connection.

connecting the module box to the heating circuit
The vibration decouplers for the connection of the heating cir-
cuit to the module box are pre-mounted in the unit. They are lo-
cated to the right of the module box after it has been inserted.
Proceed as follows:
Remove two seals from the extra box and place
them in the angle ball valves.
