HP FIRE SERVICE TURBINE INSTALLATION AND MAINTENANCE GUIDE
Before putting the fire service turbine meter into service, follow these steps:
1 Close both the inlet and outlet gate valves.
2 Turn air bleed screw on strainer cover counter-clockwise one to two turns.
3 Slowly open inlet side gate valve to pressurize meter.
4 Close air bleed screw (clockwise) when air is completely vented and no “spitting” occurs.
5 Slowly open outlet side gate valve until downstream line is pressurized.
After installation, it is important that the upstream (inlet) valve be put in the “full open” position during
service. All throttling should be done only on the downstream (outlet) side of the meter
