and Filter Ar-
rangements, to determine
the proper number and
location of Twinned Filter
Racks for your job.
2.2.6 Assemble Twinned Filter Rack(s)
For each Twinned Filter Rack you will need:
(1) Right-hand Filter Rack,
(1) Center Spreader Bar, and
(1) Left-hand Filter Rack.
Remove Filters from Filter Racks. Connect the Twinned Filter Rack parts together. Make sure
the flanges point forward, see Figure 2.2.8.
Screw the Filter Racks to the Center Spreader Bar, see Figure 2.2.9. Use #8 self-drilling screws
for each of the two Filter Racks.
Replace Filters. Filters are marked for airflow direction: remember, the filters are on the inlet
sides of the Energy Recovery Cores.

2.2.7 Install Filter Racks
Install Twinned Filter Rack(s), see Figure 2.2.10 on next page.
Set Filter Rack on Base between Core Stacks. Make sure racks are right side up (so filters can
be pulled up and out of the racks).
Pull the Filter Racks towards the edges of the Base.
The flanges on the Filter Racks should be up very close to the S-slips on the Core Stacks, see
Figure 2.2.12 on next page.

Attach Flanges to each of the ramaining
Single Filter Racks before installing them.
Place the Single Filter Racks (if any) against the Core Stacks. See Figure 2.2.11 on next page.
The back flange of the Filter Rack should tuck tight into the inner corner of the End Panel.
Align the flanges of the Filter Racks with the S-Slips on the Core Stacks, see Figure 2.2.12.
