3.2 Functional description

The stainless steel distributor/collector
"Multidis SF" serves the distribution of the fluid
to the surface heating/cooling circuits.
The valve inserts in the return collector have
a connection thread M 30 x 1.5 and can be
equipped with a thermostat or actuator for
individual room temperature control.
Printed tags for marking the surface heating/
cooling circuit connections are supplied with
the stainless steel distributor/collector. You
can fix them to the stainless steel distributor/
collector.
The heating/cooling circuits can be filled and
flushed via the fill and drain valves.
The vent plug serves bleeding during filling
of the heating or cooling system or during
operation.
Install a ball valve in front of the flow
distributor/return collector for the
isolation of the supply and return
pipe.

Set the flow rate as follows:
Carry out setting whilst the circulation
pump is in operation.
1. Open all valves in the surface heating/
cooling circuit completely.
2. Set the required flow rate by turning the
cylinder.
Clockwise = Reduction of the flow rate /
close completely.
Anticlockwise = Increase of the flow rate /
open completely.
The set flow rate can be read off
at the red indicator ring inside the
sight glass. The scale shows values
between 0 and 5 l/min.
3. Carry out setting of all heating/cooling
circuits.
4. Check the set values and readjust if
required.
