Dual Filtration (GEH 0.5 to 5 ton and EXH
0.5 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.
3. Install the 1”or 2” filter.
Sound Attenuation Pad
For sound-sensitive installations, a vibration pad (field
provided) should be placed beneath the horizontal or
vertical equipment. For the horizontal unit, the pad should
be approximately twice the size of the unit foot print. For
the vertical unit, the pad should be 0.5 in. thick, and equal
to the overall unit foot print.
Hanging the Horizontal Unit
WARNING
Risk of Unit Dropping!
Failure to follow instruction below could result in death
or serious injury. To prevent modules/subassemblies
from dropping, ALWAYS place, assemble, and suspend
them one at a time.
To hang the horizontal configuration (see
1. Install the hanging isolators (located in the return-air
section of the unit) into the four hanging brackets.
