Application
Considerations
Hanging the Horizontal
The horizontal unit GEH is a ceiling hung unit. It is
usually applied as a totally concealed unit above an
acoustical ceiling grid.
Because the GEH is equipped with several inlet and
discharge arrangements, it allows for numerous
application needs, and is field convertible at the jobsite.
The GEH and GEV units are equipped with a dual
sloped, non corrosive drain pan to enhance drainability
and indoor air quality.
When hanging the horizontal GEH design, local building
codes may require the unit to be pitched approximately
1/4-inch per foot toward the drain in both directions.
This aids in condensate removal from the drain pan. See
Figure 41 for unit slope.
Hanging Devices and
Duct Attachments
All GEH units are shipped with factory mounted hanging
brackets and rubber isolation grommets. The
provided.
One-inch duct collars are provided for field duct
attachment to the supply-air outlet. The duct collars,
filter racks, filter and grommets are field installed. These
items are shipped in an inclosure external to the unit.
See Figure 42 for unit duct collar and hanging device
installation.
Flexibility of the GEH allows for dual filtration in a free
return application. With the field installed dual filtration
accessory, filter maintenance of the unit is significantly
less.
The accessory package includes both the bottom and
top filter rack, and one, 1-inch or 2-inch filter. Table 3
provides dual filtration accessory numbers appropriate
to unit size.
