Initial operation

CAUTION!
Danger of material damage in the pipeline system.
When commencing the initial operation via the main pipeline there is the danger that the initial pressure is too high and the pipeline
system is damaged.
► Starting the initial operation with an outlet hydrant (H) is recommended.
► To protect the NeoFlow pressure reducing valve (N) from mechanical strain, all components of the pipeline system must be
securely fastened to the ground or another solid object before commencing the operation of the system.
1. Make sure that the inlet and outlet shut-off valves (A and O) and the hydrant (H) are fully closed.

WARNING!
Risk of injury due to uncontrollable exit of the medium!
If the NeoFlow pressure reducing valve (N) is leaking or the ball valves KH 4-6 on the NeoFlow pressure reducing valve (N) are not
closed, the medium may exit uncontrollably under high pressure.
► Assume a protected working position.
► Wear protective clothing, if required.
► In case of leaks: close the inlet shut-off valve (A).
► Close the ball valves KH4-6 when not in use.
3. Carefully check the piping system for leaks.
