Length 130 mm and G 1 male thread
Item no. 1404578, set no.1, DN 20, G
Item no. 1404579, set no. 1, DN 20, G
Item no. 1404580, set no 1, DN 25, G 1, angle pattern
Item no. 1404581, set no. 1, DN 25, G 1, straight pattern
5.2 Application
The heat meter connection sets are suitable for left and
right hand side connection to the distributor/collector.
Fit the components as shown in illustr. 6.1 or 6.2, flat
seals are included.
The connection to the stainless steel distributor/collector
"Multidis" is flat sealing, too.
Tighten all connections.
To guarantee a long and trouble-free function of all
components, the installation of an Oventrop strainer is
recommended.
The risers are, for instance, connected to the female
threads of the ball valves by use of the Oventrop
"Combi-System":
– "Copipe" Composition pipe
– "Cofit P" Press fittings
– "Cofit PD" Press fittings
– "Cofit S" Screwed fittings
A thermal and sound insulation of the pipework
according to the valid rules, decrees, standards and
guidelines has to be carried out.
