MODIFYING AIR HANDLER HOUSING

1. Turn housing upside down.

2. Reinstall the support bar using 4 screws (Figure 11)

3. Sizes 18 & 24 Units Only: Use three strips of the

provided insulated tape (Part I) and attach to exposed

side of the blower housing (Figure 12). This is required

only for these sizes to prevent sweating in downflow.

NOTE: Removing the blower housing to perform this task is

optional.

NOTE: If the insulated tape covers the wiring diagram, an

additional wiring diagram is included in the kit,

4. Using the two insulated coil support brackets (Part B and

six #8-18 x 1” screws (Part F) provided in the downflow

kit, install the coil supports brackets to the inner sides of

the cabinet (Figures 13 and 14).

5. Position the front and rear insulated air seals (part E)

onto the downflow coil support brackets (Figure 15). Be

sure the seals seat against the back and front of the air

handler and that the front will seat against the access

panel when reinstalled.
