fittings (generally ½” (12.7 mm)) on the filter vessel, install a ball valve and run to
drain. If the filter vessel is not equipped with drain fittings, it is recommended to install
a tee between the filter vessel outlet fitting and outlet ball valve.
Connect a drain line (1/2” ~ 3/4” (12.7 ~ 19.05 mm) recommended) with a small ball
valve to the bottom of the tee and run this line to a suitable drain.
Cartridge Replacement
Cartridge replacement is recommended when the pressure drop across the filter vessel
inlet and outlet exceeds 10 to 12 psig (69 to 83 kPa). Before performing any service on
the SCF filter, disconnect power from the pump motor at the main circuit breaker. Lock
out and tag the circuit breaker.
Isolate the filter vessel from the pump and process by closing the inlet and outlet ball
valves. Fully open the drain valve to vent any remaining pressure and to drain the filter
vessel. Separate the vessel top lid from the vessel body and remove filter cartridge(s).
Make sure that the vessel housing and all o-rings and sealing surfaces are cleaned
before installing new cartridge filters. Install new cartridges and reassemble filter vessel
lid. If so equipped, grease top lid studs and tighten in a ”star” pattern until all are
tightened to 12 ft.-lbs. (16.3 n-m). Close the drain valve and open the filter inlet and
outlet valves. Return the SCF filter to service.
