6.4 Horizontal Right Installation
Side drainpan extension must be removed for all models except :
ARUF47D14**, ARUF61D14**, ASPT61D14**.
Refer to Figure 6 and 7 for the location of the components referenced in the following steps.
1. Before inverting the air handler, remove blower access panel and coil access panel. The coil access panel and tubing
panel may remain screwed together during this procedure. Remove and retain the seven (7) screws securing the coil
access panel to the cabinet and the six (6) screws securing the blower access panel to the cabinet.
2. Slide the coil assembly out from the cabinet. Use the drain pan to pull the assembly from the cabinet.
NOTE: DO NOT USE MANIFOLDS OR FLOWRATOR TO PULL THE COIL ASSEMBLY OUT. FAILURE TO DO SO MAY
RESULT IN BRAZE JOINT DAMAGE AND LEAKS.
3. Removal of the center support is required on units
with 21" wide cabinet. Remove and retain the two
(2) screws that secure the center support to the cabi-
net. Remove the center support.
4. Using the drain pan to hold the coil assembly, slide
the coil assembly back into the cabinet on the
downflow brackets as shown in Figure 8.
5. Re-install the center support (if removed) using the
two (2) screws removed in Step 4.
6. Re-install the access panels removed in Step 1 as
shown in Figure 9.
7. The bottom right drain connection is the primary drain
for this application and condensate drain line must
be attached to this drain connection. The bottom left
drain connection is for the secondary drain line (if
used). Install the PVC plug that was removed from
the side drain pan primary connection and install it
on the vertical primary connection.
NOTE:
If removing only the coil access panel from the
unit, the filter access panel must be removed first. Fail-
ure to do so will result in panel damage.
