Installation, Operating & Service Instructions
Installation
Remove the housing protectors from the inlet and outlet connections. Make certain that
connections are free of any debris.
Important: Be sure to correctly identify the inlet and outlet connections to avoid piping the unit
backwards. The unit will not perform properly if connections are reversed.
Provide shut-off valves in the inlet and outlet piping as close to the unit as possible for
isolating the unit from the system when cartridge replacement is necessary. (See illustration)
Connect the housing into the piping system with a minimum number of turns and fittings, pipe
dope and Teflon tape especially on the inlet side.
For installations on fuel dispensing pump, connect the fuel delivery hose directly to the outlet
connection.
Provide room for the housing to clear the cartridge during change-out. 2 inch base clearance
required.
We recommend installation of a differential pressure gauge so that the differential pressure
across the housing can be monitored. This allows accurate determination of when the
cartridge should be changed. Part numbers 72694 or 72783 are differential pressure gauges
specifically designed to be used on FBO-10/14.
For Absorptive Cartridges used in aviation fuel or diesel fuel service, Always install a
differential pressure gauge or other means of determining the differential pressure. See
attached flow curves for applicable flow rates.
IMPORTANT: On systems where pressures can exceed 75 psi, a pressure bypass around
the pump must be installed to protect the cartridge and the system from a high pressure shock
or sudden cartridge seal-off due to a slug of water in the product.
