Installation of a Varicel DH Double Headered
Filter
These instructions are for the installation of a VariCel
DH filter (nominal 12” deep double header) into 16 ga.
galvanized holding frames.
• The latches needed for this application are four
(4) spring latches, P/N 026-35778-006
(as shown
in Fig.2-98.
• Two latches should be attached on each side of
the filter frame.
• The latches should only be installed, two (2) per
side of the frame. There should be no latches
used on the top or bottom. This is done to match
the holes in the filter frame, used to secure the
latch to the filter.
See Fig.2-106
for the sets of
knockouts that should be used for the latches.
