Downflow Coil Installation
NOTE: In downflow installation with a 4-way multipoise furnace, break
off perforated duct flanges on furnace. See furnace Installation
Instructions.
Horizontal Coil Installation
In horizontal installation with a 4-way multipoise furnace, break off
perforated duct flanges on furnace. See furnace Installation Instructions.
For condensate connections, use the correct drain lines per Fig. 14.
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 (Fig. 8).
NOTE: In horizontal applications, the vertical condensate drain ports
must be plugged. When connecting condensate drain lines to the
horizontal drain ports, transfer the horizontal drain plugs to the vertical
drain pan ports to assure that all vertical drain ports are plugged.
