LIMITATIONS

These coils should be installed in accordance with all national and local
safety codes. Refer to Table 3.

SECTION III: COIL INSTALLATION

DUCT FLANGES

Three duct flanges are provided to attach ductwork to the coil. The
flanges are included in the parts bag along with three tie plates. Tie
plates are used to secure the coil to the furnace or to the modular air
handler as shown in Figures 5, 6, 8, 9, 11, & 12. Using the screws
included in the parts bag, duct flanges are attached as shown in Figure
4 (to secure the duct to the coil). If the flanges are not used, they may
be discarded.

Downflow (CF/CM) or Horizontal Right (CM):

The coil cabinet has a factory installed transition angle on the bottom
front side of the cabinet. For downflow and horizontal applications with
a furnace, this angle must be repositioned to the top front side of the
cabinet.

1.

Remove two screws that fasten transition angle to bottom front of
cabinet.

2.

Remove two screws from top front side of cabinet.

3.

Remove transition angle, rotate angle 180

° 

end for end, and secure

to top front side of cabinet.

4.

For installation with modular air handling unit, remove the transition
angle, and discard it.
