Initial operation

7.2 Installation
CAUTION
Failure to comply leads to a risk of personal injury!
Temperature changes can lead to longitudinal or lateral forces in the piping system with the
risk of damages of the Diaphragm Valve. Make sure that the Diaphragm Valve is mounted in
one of the following ways:
- Mount the diaphragm valve as a fixed point with the designated fastener or
reinforce the piping directly before and after the diaphragm valve with suitable
supports.
- Diaphragm valves and piping must be aligned.
Loosen the union nuts and push them towards the designated piping end.
Depending on the type of piping end, connection parts are cemented, screwed or welded.
The Georg Fischer Planning fundamentals include additional information.
Diaphragm valve is then positioned between the connecting parts
Manually tighten the union nuts
Only identical materials can be joined together
Pipe sections with solvent cement connections should be rinsed unpressurized with water
after the drying time (see chapter jointing methods in the Georg Fischer Planning
Fundamentals)
Only identical materials can be joined together see chapter jointing methods in the Georg
Fischer Planning Fundamentals)
8 Initial operation
CAUTION
Risk of injury by increased control pressure and / or cavitation!
Higher control pressure or mechanical aids or cavitation can lead to damages of the
Diaphragm Valve.
Use mentioned control pressure to actuate the diaphragm valve.
Use valve only at optimal operation conditions.
Check that all valves are in the required open or closed position during the
implementation
Fill the piping system in accordance to the technical data of all installed and releated
components and de-arate completely.
