Join the JRG fitting and the blind flange using
the supplied bolts and washers.
Make sure that the O-ring remains
placed in the groove provided. Tighten
the bolts crosswise as it is common
practice with flanged connections.
If JRG fitting and blind flange are used
together, the backflow preventer core
must be removed since it would easily
be overlooked when troubleshooting in
case of malfunction.
