Horizontal right is the default factory confi guration for all models.
Conversion to Horizontal Left:
A vertical upfl ow unit may be converted to horizontal left by removing indoor coil
assembly and reinstalling coil as shown for left hand air supply. See Figure 11.
Rotate the unit 90° into the horizontal left position, with the coil
compartment on the right and the blower compartment on the left.
Reinstall the indoor coil 180° from original position. Ensure the retaining
channel is fully engaged with the coil rail. See Figures 11 and 12.
An additional field supplied drain pan kit is recommended when the unit
