Ducted Filter Rack (GEH .5 to 5 ton and
EXH .5 to 6 ton only)
Dual Filtration (GEH .5 to 5 ton and EXH .5
to 6 ton)
Note:
The dual-filtration design is typically used in a free-
return application.
The horizontal, GEH and EXH model, allows the installer
flexibility in design applications such as a dual filtration
option. With the dual filtration design, the unit will contain
a lower static which translates into a decrease in filter
maintenance. For installation of a dual filtration accessory
for the GEH and EXH model, verify that an extra set of
return-air filter racks and filter have been ordered from the
factory. This accessory will be shipped separate from the
unit, and should be located in a separate box than the unit.
1.
Remove the return-air side panel from the GEH and
EXH unit. This panel is held in place by screws.
2. Install the top/bottom filter rack at the new opening.
The adjustable filter rack is held in place with four
screws that once held the panel.
