5. Construction and function

5.1. Summary / Functional description
The stainless steel distributors/collectors "Multidis SF"
are designed for use in surface heating and cooling sys-
tems with circulation pump.
The risers can be connected to the distributor/collector
from either the left or right hand side.
The brackets allow the fixing of the distributor/collector
in the cabinet or directly on the wall. The stainless steel
distributors/collectors can be equipped with the ball
valves displayed in illustr. 4.3. The flat sealing ball valves
are directly connected to the collar nuts (G 1 female
thread) of the distributors/collectors.
Standard heat meters G 1 and G
When choosing the cabinet, please take into considera-
tion that this will result in an enlarged depth and length
of the stainless steel distributor/collector "Multidis SF".
The heating/cooling circuit connections have a G
male thread according to DIN EN 16313 (cone "Euro").
Printed tags for marking the heating/cooling circuit con-
nections are supplied with the distributors/collectors.
