Hanging the Horizontal
The horizontal unit GEH A is a ceiling
hung unit. It is usually applied as a
totally concealed unit above an acousti-
cal ceiling grid. Because the GEH A is
equipped with several inlet and dis-
charge arrangements, it allows for
numerous application needs.
When hanging the horizontal design,
the unit should be pitched approxi-
mately 1/4-inch (6.4 mm) per foot
toward the drain in both directions.
This aids in condensate removal from
the drain pan.
(See Figure 29 for unit
installation.)
Hanging Devices and Duct
Attachments
All GEHA units are shipped with a fac-
tory mounted hanging bracket and rub-
ber isolation grommet. The 3/8 -inch
(9.5 mm) all-thread and 3/8 -inch
(9.5 mm) washer and nut are field pro-
vided.
One-inch duct collars are provided for
field duct attachment to the supply-air
outlet. The duct collars, filter racks, fil-
ter and grommets are field installed.
These items are shipped in an inclo-
sure external to the unit.
