INSTALLATION
Install the housing at a convenient point in the line. Note “Inlet” and “Outlet” markings on the cast
head which indicate direction of flow. DO NOT install the housing backwards.
Provide room for the housing shell to clear the cartridge during change-out.
It is good practice to install 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 number 10678, as described on Form 1715 (PN 09-880) is a differential pressure gauge
specifically designed to be used on VF-61. NOTE: PN 09-880 Pressure Gauge is not UL tested or
approved.

CARTRIDGES USED IN DIESEL FUEL SERVICE,
ALWAYS
INSTALL A
DIFFERENTIAL PRESSURE GAUGE OR OTHER MEANS OF DETERMINING THE
DIFFERENTIAL PRESSURE. For diesel fuel service, flow rate should be kept between 15 and 50
gpm. Consult factory for other flow applications.
On systems where pressures can exceed 75 psi, a pressure bypass around the pump should 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.
Valves ahead of and behind the housing may be required to isolate it during cartridge change-out.
CARTRIDGE CHANGE-OUT
Replace the cartridge when the differential pressure exceeds 25 psi, after 1 year of service, when the
flow is significantly reduced, or if pressure has been steadily climbing and then begins to decrease –
whichever occurs first.
IMPORTANT SAFETY PRECAUTION:
MAKE CERTAIN FILTER HOUSING IS COMPLETELY VENTED
BEFORE OPENING HOUSING.
1. Turn off pump.
2. Close isolation valves (if any) and open the valve vent at the top.
3. Place a bucket under the housing to contain any spilled liquid.
4. Drain all liquid from the housing through the bottom plug.
5. Loosen the four bolts and rotate out and down to clear the top clamp.
Drop the housing shell.
Remove the spent cartridge.
