The manifold can be mounted in vertical position, with outlet facing up or down, or in horizontal position at a storey floor.
Always depressurize and cool the system before doing any installation and maintenance work.
The mounting consoles are available as accessories.
The filling and drainage valve is suitable for connecting Viega hose screw fittings, article no. 117 696 and 109 073.
Assembly
-
Assemble the supply flow beam, the return flow beam, and the mounting console (available separately).
NOTICE!Align the supply and return flow beam centrally to one another.
-
Fasten the industry manifold to the wall or ceiling.
-
Check the valve casing for contamination and damage.
-
Connect the pipes.
-
Use Viega screw fittings or press connectors to connect the pipes.
-
Flush the system and perform a leakage test before commissioning.
Settings
Shutting valves off
-
Unscrew the closing cap using a size 19 fork spanner.
-
Turn the size 5 Allen key clockwise to close the return pipe screw fitting.
-
Unscrew the closing cap and tighten it with max. 15 Nm using a size 19 fork spanner.
