In order to avoid an overpressure condi-
tion and possible equipment damage,
pressure gauges should always be used
to monitor pressures during startup.
1. Slowly open the upstream shutoff valve.
2. Slowly open the downstream shutoff valve.
3. Check all connections for leaks.
4. Make final control spring adjustments according to
the adjustment procedures.
Adjustment
The range of allowable pressure settings is marked on
the nameplate (figure 2). If a pressure setting beyond
this range is necessary, substitute the appropriate
regulator control spring. Change the nameplate to
indicate the new pressure range.
Before increasing the setting, refer to tables 2, 3, or 4.
Review the pressure limits for the control spring range
being used and be certain that the new pressure setting
will not result in an overpressure condition.
