Horizontal Coil Installation
The unit can be installed on a work platform, secured to roof truss in
attic, suspended from hangers on floor joists in crawl space, or installed
on blocks. It is designed to allow airflow in either direction, to mate with
horizontal-left or horizontal-right furnace installations. Ensure coil
cabinet is level side to side and front to back. It is allowable to add up to
1/2-in. additional slope over length and depth of coil cabinet in the
direction of drain pan connection.
Horizontal-Right Installation
1. Use field fabricated attachment plates to secure coil to furnace. See
Fig. 6.
2. Use self-tapping screws to mount attachment plates to coil casing.

3. Connect furnace snugly against coil casing.
4. Use self−tapping screws to attach furnace. See Fig. 6.
5. Seal joint between coil casing and furnace to create an air tight seal
using locally approved materials.
6. Use cork tape to create air seal between the undersides of the pan
extension and front of the vertical drain pan as shown in Fig. 7.
7. Install included condensate pan extension and two corner screws as
shown in Fig. 7.
8. If coil is wider than furnace, use 4−in minimum transition and self
tapping screws to attach furnace. See Fig. 4.
