GAGE INSTALLATION
1. The connecting tubing between the PFA Ellipse and the gage should be as short as possible
and should slope down a minimum of 1 inch per foot.
2. Secure and support tubing to prevent sagging and/or vibration.
3. Care must be taken to ensure that the head heights are even.
4. A bleed line should be run from the gage vent valves to a pan or drain.
VIII.
GAGE OPERATION
1. Identify Hi and Lo pressure inlets on the gage.
2. Ensure by-pass valve (blue) is OPEN!
WARNING
WARNING:
Gage may be damaged if initially pressurized with the by-pass valve closed.
3. Connect gage to corresponding Hi and Lo pressure taps of the PFA Ellipse (via 3-valve
manifold, if being used).
4. Open Hi and Lo instrument valves on the PFA Ellipse.
5. Alternately open the Hi and Lo vent valves to purge the lines.
6. When venting is complete, close the by-pass valve to begin taking reading.
