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.
11. Close the vent when the housing has filled. Check all fittings and the head/shell junction for leaks. REPLACEMENT PARTS The VF-61UL is shipped with a Buna-N O-ring installed. When ordering replacement O-rings from Velcon, specify: G-0986 for Buna-N (UL Approved)
