These instructions are for installing 2” panel lters into type
8 holding frames.
•
Latches needed for these applications are four (4) clips as
indicated in the table.
• 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 (see Figure 38). Repeat the
installation process with the remaining latches in the other
three corners.
4. Rotate all of the latches outward, and insert the lter into
the frame making certain that the pleats run vertical.
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 39).
These instructions are for installing 4" panel 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 lters with
a 13/16” single header in combination with a nominal 2”
prelter. The second set of knockouts should be used for
nominal 4” 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.
Repeat the installation process with the remaining latches.
