Mounting
1 . Mount panel using the 4 mounting holes (A) . Note: Use 3/8" or 9 mm bolts .
4.3
Connect Pressure Lines
1 . Make sure the pressure of the supply line is off and attach the line to the filter
inlet port (C) . Note: Max pressure 2750 psig / 190 bar natural gas .
2 . Connect pipeline pilot regulator spring case port to ER5050FX-1-002 control port (D) .
Note: An additional Out Port (G) can be used to monitor the control port pressure .
3 . Attach a vent line to exhaust port (F) . Note: The vent line must be installed per federal,
state and local codes . The exhaust vent line must be at atmospheric pressure .
4 . Attach a vent line to relief valve (B) . Note: The vent line must be installed per federal,
state and local codes and must be plumbed separately from EXH port (F) .
5 . An optional pressure gauge can be attached above either filter port (E) to measure inlet
pressure and/or pressure differential across filter elements. Note: The element must be
replaced when the differential pressure reaches 10 psid, 12 psid maximum .
6 . It is recommended to install valves into the drain port of the filters (H) to facilitate
draining liquids from the coalescing filters as needed.
