Air Discharge Conversion
These units are shipped for Vertical Airflow operation as seen in
Figure 1 Positions 1 thru 4, but may be converted for Horizontal
Airflow operation illustrated in Figure 2 Positions 1 thru 4.
Conversion Example:
Convert Vertical Airflow Position 1 to Horizontal Airflow Position
1 as follows:
1.
Remove the front blower panel from the blower section and
set aside. This allows access to the clamps that hold the
blower section to the evaporator section.
2.
Remove the bolts and clamp angles that hold the coil
section and blower section together.
3.
Place the panel removed in Step 1 on top of the blower
section and screw together.
4.
Set the blower section aside.
5.
Remove the evaporator section rear panel and set aside.
6.
Rotate the blower section and mate it to the hole left when
the panel was removed in Step 5.
7.
Bolt and clamp the two sections together.
8.
Place the panel remove
1.
d in Step 5 on top of the evaporator section and screw
together.
NOTE:
1 inch blower duct flange shipped with air handler.
