STEP 4: Once all four corner latches have been tightened
within 1/4” of the leg extension coupling, complete the
installation by tightening each corner until the latch and leg
extension coupling meet. This is illustrated in Figure 108.
Once all four corners have been tightened the lter should now
be properly seated and sealed.
Repeat the process with all remaining lters working from the
bottom to the top.

STEP 6: Place a latch so that the 2 tabs of the latch overlap
the prelter frame on each side of the corner. Slide the latch
inside of the leg extension and align the latches’ cap screw
with the threaded coupling on the end of the leg extension and
tighten using the hexkey. See Figure 111.

Tighten the cap screw until there is an approximately 1/4” gap
between the latch and the leg extension coupling as shown in
Figure 112. Repeat this step with all 4 corners.
