CAUTION

Concerning inlet-side distance “C” (Fig. 1-4)

The minimum for distance “C” is 6" if there are no obstructions on the outlet side (wall *1 side) and *2 or *4 is not present. In all other cases, the minimum for distance “C” is 8".

If the unit is installed with the outlet side facing wall *1, then there must be no obstructions on 2 of the remaining 3 sides: *2, *3, *4.

If wall *1 is on the outlet side (Fig. 1-4), or if obstructions are present on all 3 sides *2, *3, and *4 (Fig. 1-4), then the minimum distance for “A” and “B” is 80" (Fig. 1-5). Even if there is no wall on the outlet side, a minimum of 3.3 ft. is required.

Installation requirements

provide a solid base (concrete block, 4"×16" beams or equal), a minimum of 6" above ground level to reduce humidity and protect the unit against possible water damage and decreased service life. (Fig. 1-6)

use lug bolts or equal to bolt down unit, reducing vibration and noise.
