WARNING

Improper installation, adjustment, alteration,

service or maintenance can cause personal injury,

loss of life, or damage to property.

Installation and service must be performed by a

licensed professional installer (or equivalent) or a

service agency.

CAUTION

Physical contact with metal edges and corners

while applying excessive force or rapid motion can

result in personal injury. Be aware of, and use

caution when working near these areas during

installation or while servicing this equipment.

GENERAL

This kit is used to modify air handler units for use in

downflow applications. The procedure requires that the

installer remove the evaporator coil and re-install it for

downflow air discharge application.

Figure 1 shows the air handler unit as configured at the

factory. As shipped, some models are configured for

upflow air discharge, and some models are configured

for either upflow or horizontal left-hand air discharge.

Figure 2 shows the air handler unit after re-configuring

for installation in downflow air discharge applications.

NOTE: A downflow combustible floor base is not required for the

applicable air handler.

REMOVING COIL FROM HOUSING 1. Remove the connection panel, access panel, and the blower panel. Keep all panels and screws; these will be re-used when reassembling. CAUTION 2. Remove the support bar. Keep the bar and 4 screws for later use. Be certain all power has been disconnected from the air handler before beginning work. 3. Remove all upflow and horizontal drain pan mounting brackets (Figures 4 and 5). Discard these brackets. WARNING 4.

MODIFYING INDOOR COIL 1. Remove 4 screws attaching coil to drain pan (Figure 7). 4. Install both outer coil slab shields (Part D, two each) using the provided tie-wraps (Part G, four each) (Figure 9) and secure to return bends on both ends. Ensure the shields are within 1/4” from the drain pan. 2. Remove the drain pan from the coil and replace it with the kit-provided insulated drain pan (Part A). Reinstall the 4 screws. 3.

MODIFYING INDOOR COIL (CONT.) 5. Wrap the coil suction manifold and TXV bulb with the provided insulating foam tape (Part H) to prevent condensate from dripping or blow off the manifold, as shown in Figure 10. FIGURE 10 A. NOTE: Failure to install all shields (steps 3 and 4), or the adhesive back insulating foam (step 5) can result in condensate blow-off and subsequent damage to the building and its contents.

MODIFYING AIR HANDLER HOUSING 1. Turn housing upside down. 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). 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).
