E SERIES INSTALLATION MANUAL
Installing Horizontal Units
Horizontal units are available with side or end discharge and may be field converted from one to the other by replac-
ing the discharge panel with a new panel which must be ordered separately. Horizontal units are normally suspended from
a ceiling by four or six 3/8-inch diameter threaded rods. The rods are usually attached to the unit by hanger bracket kits
furnished with each unit.
Lay out the threaded rods per the dimensions below. Assemble the hangers to the unit as shown. Securely tighten the
brackets to the unit using the weld nuts located on the underside of the bottom panel. When attaching the hanger rods to
the bracket, a double nut is required since vibration could loosen a single nut. To allow filter access, one bracket on the filter
side should be installed 180° from the position shown in the figure below. The unit should be pitched approximately 1/4-inch
towards the drain in both directions to facilitate the removal of condensate. Use only the bolts provided in the kit to attach
hanger brackets. The use of longer bolts could damage internal parts.
Some residential applications require the installation of horizontal units on an attic floor. In this case, the unit should
be set in a full size secondary drain pan on top of a vibration absorbing mesh. The secondary drain pan prevents possible
condensate overflow or water leakage damage to the ceiling. The secondary drain pan is usually placed on a plywood base
isolated from the ceiling joists by additional layers of vibration absorbing mesh.

CAUTION: Do not use rods smaller than 3/8-inch diameter since they may not be strong
enough to support the unit. The rods must be securely anchored to the ceiling.
