Align the filter downstream fitting (4) in the VCR nut
(5) and thread the nut onto the fitting so it is hand-
tight. The filter should be installed with the printed
arrow pointing in the direction of the gas flow.
Using two wrenches, tighten the filter’s male VCR
connector (4) into the female nut (5) approximately
1/2 turn beyond hand-tight.
Thread the 8VCR female coupling (2) onto the filter
upstream connector (3). Place a new 8VCR o-ring
securely against the sealing surface of the filter
upstream fitting inside the 8VCR female
coupling.
Thread the VCR x tube adaptor fitting (1) from the
original molstic inlet into the 8VCR female coupling
(2). The coupling should be threaded onto both
male fittings so that the o-ring is centered in the
coupling.
Using two wrenches, tighten the two male nuts from
the tube adaptor and filter upstream fitting against
each other in the coupling. The o-ring connection
should be tightened only 1/2 turn past finger-tight.
Over-tightening VCR connections will damage the sealing
beads and/or o-rings and possibly cause system leakage. Do
not re-use metallic VCR gaskets.
