4. Insert the lter into the frame making sure that the pleats
are vertical.
5. After the lter has been placed into the frame, grasp the
loose end of the latch and place it over the lter frame, so
that the latch secures the lter into the frame (see Figure 41).
Repeat for the remaining latches.
6. The lter should now be securely installed into the frame
(see Figure 42).
These instructions are for installing single-header rigid lters
into type 8 holding frames.
• Latches needed for these applications are four (4) clips as
indicated in the table on page 32.
• A single latch should be installed at each of the four (4)
corners of the frame.
• The latch ts into the set of knockouts, which consists of
two (2) rows of three (3) knockouts. The row of knockouts
closest to the gasketing should be used for nominal 1”
lters or lters with a 13/16” single header. The second set
of knockouts should be used for nominal 2” lters.
1. Insert the straight end of the latch between the two (2)
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 three (3) knockouts, but
should be able to freely rotate.
Repeat the installation process with the remaining latches.
4. Rotate all of the latches outward, and insert the SH lter
into the frame. The bulk of the lter should be inserted through
the frame, protruding out the backside. Only the header of
the lter should be contacting the ange of the frame.
5. After the lter has been placed into the frame, grasp the
circular end of the latch and rotate it across the corner of the
lter.
Push the end of the latch towards the lter, until the latch
catches beneath the knockout on the frame.
Repeat for the remaining latches.
6. The lter should now be securely installed into the frame
(see Figure 42).
These instructions are for the installation of a Rigid DH Double-
Headered lter (nominal 12” deep double header) into a type
8 holding frame.
• The latches needed for this application are four (4) clips as
indicated in the table on page 32.
• Two latches should be attached on each side of the 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. See Figure 43 for the
sets of knockouts that should be used for the latches.
