(13 mm) pry locations — two holes on front
flange and two holes on rear flange. Refer to
Figure 8, Detail K, to aid in aligning the hopper
flange with the module flange.
With filter module still supported, use hardware (refer to
Figure 8, Section P-P) to bolt the hopper and filter
module together. Securely tighten all hardware at the
filter module and hopper. Recheck leg assembly sway
braces to ensure they are tight. Install fasteners (bolt,
flat washer, lock-washer, nut) to all four pry locations.
Disconnect lifting slings and spreader bars used for
installation.
MULTIPLE, BOLT-TOGETHER MODULE
SECTIONS
For units that have multiple, bolt-together module
sections, remove the row of filters from the modules
nearest the bolting flange (refer to Section 6.1). Protect
the doors and filters removed by placing in a safe area
away from work area. Identify the different module
sections. There are left (bolt flange on the right side),
right (bolt flange on the left side) and possibly center
(bolt flanges on both sides) module sections.
Install all hopper/leg assemblies as previously described.
With multiple hoppers, the leg assemblies should be
bolted together (refer to Figure 5, Section F-F).
Apply two ribbons of sealant to only the first hopper
flange to create “figure 8” pattern around mounting
holes (refer to Figure 7, View H).
Place the appropriate filter module onto the hopper/leg
assembly to which the sealant has been applied,
positioning filter module corner holes over alignment
pins in leg gussets (refer to Figure 8, Detail K). Drift pins
will also be useful for locating the module section onto
the hopper.

(13 mm) pry locations — two holes on front

flange with the module flange.
With the filter module still supported, use hardware
(refer to Figure 8, Section P-P) to bolt the hopper and
filter module together. Securely tighten all hardware at
the filter module and hopper. Recheck leg assembly
sway braces to ensure they are tight. Install fasteners

locations.
Disconnect lifting slings and spreader bars used for
installation.
Apply sealant to the next hopper to receive a filter
module (refer to Figure 7, View H). Apply sealant to the
side bolting flange of the next filter module to be
installed using the “figure 8” pattern (refer to Figure 9,
Detail J). Place this module on its hopper. Use the
hardware provided (refer to Figure 9, Detail L) and bolt
the module sections together. Bolt the filter module to
the hopper (refer to Figure 8, Section P-P). Securely
tighten all hardware at the filter module and hopper.
Recheck leg assembly sway braces to ensure they are
tight. Install fasteners (bolt, flat washer, lock-washer,
nut) to all four pry locations.
Disconnect the lifting slings and spreader bars used for
installation.
Repeat this process until all the module sections are in
place, securely fastened and anchored to the foundation.
Recheck all hardware connections to make certain they
are securely tightened. Remove lift slings and spreader
bars and clear all tools from the work area.
NOTE: Make certain all bolts (including the anchor
bolts) are properly tightened before proceeding
with the remainder of the installation.
Install all cartridge filters removed at the beginning of
the installation process and install the filter access
doors (refer to Section 6.1).
CLEAN AIR SECTION BOTTOM ACCESS
PANEL INSTALLATION
The bottom access panel and its gasket are shipped
loose with installation hardware. If the bottom access
will not be used for discharge ductwork, attach the panel
to the bottom opening using the hardware provided.
For top-mount blower packages of 20 HP (15 kW) or
larger, an additional set of support legs is provided.
The additional support legs must be mounted under the
filter module supporting the blower package (refer to
Figure 10). Bolt the mounting plate to the bottom of the
appropriate clean air plenum with the hardware
provided. Bolt the leg assemblies to the mounting plate
!
CAUTION
In preparing to attach the filter module to the hopper,
connect lifting slings and spreader bars to all filter
module lifting lugs with clevis pins. Distribute the load
evenly. Location must be clear of all obstructions, such
as utility lines or roof overhangs.
