Installation
4. Repeat the latch installation with the remaining
latches; note the orientation of the latch to the
knockouts on Fig.2-110.
5. Insert the VariCel DH lter into the frame. While
holding the lter in the frame, grasp the loop on
the end of the latch and pull it until it stretches
over the header and rests into the pre-drilled hole
in the header of the lter (see Fig.2-111). Repeat
this with the remaining latches.
Installation of Prelter Latches
6. To install the prelter latches, slide the end of
the latch with the 180 ° turn, over the edge of the
header, as shown in Fig.2-112. The latch should be
installed at the approximate midpoint of the lter
leg.
The prelter latch should be slid over the header
as shown in Fig.2-112.

Installation of a 2” and 4" Prelter in
Combination With a Double Header Final
Filter
These instructions are for installing either a 2” or 4"
prelter (typically PerfectPleat, Premium or Premium
HM pleated lters) used in combination with a
VariCel DH (nominal 12” deep) nal lter into 16 ga.
galvanized holding frames.
• Two sets of latches are needed for these applica-
tions. Four (4) spring latches, P/N 026-35778-
006 are used to hold the VariCel DH into the
frame. In addition, four (4) prelter latches, P/N
026-36339-001 are used to hold the 2” and P/N
026-36339-000 are used to hold the 4” prelter
onto the face of the VariCel DH lter.
• For the spring latches, two (2) latches should be
attached on each side of the lter 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 lter frame, used to secure the
latch to the lter.
Installation of Spring Latches
1. Insert the straight end of the latch between the
knockouts furthest from the corner.
2. Using a moderate amount of pressure, force the
latch over the third knockout.
3. The latch installation should now be complete.
The latch should now be “trapped” within the 3
knockouts (see Fig.2-110).
