Operation Recommendations:

Admit pressure slowly by throttling gauge cock. The maximum, pressure at which a pressure gauge is continuously operated shall not exceed 75% of full scale pressure.
The gauge selected should have a full scale pressure of approximately twice the intended operating pressure.
If it is desirable to compensate the indication for head effect in the piping leg it can be accomplished by removing bezel ring and window and resetting pointer using the pointer
adjusting screw.
Relieving Case Pressure: Filled cases or other sealed cases must be vented to avoid internal pressure, which can affect accuracy.
After installation, cut or pierce fill plug at top of case for best accuracy.
