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. (See Figure 30 for unit duct collar and hanging device installation.)
