NOTE FOR FNH
The lockable manual override with hexagon socket and lock nut (FNH) could be used
to override the pressure control function of the valve. Be aware that the valve can not
full its pressure control function if the FNH is screwed in and locked. This can lead
to excessive pressure and cause breakage or failure of the components if no parallel
pressure relief protection is present.
The FNH should never be screwed in and locked when used in conjunction with
a running system!
