air temperature does not exceed maximum 115°F
constantly.
allow enough room around the unit for air intake/
exhaust and possible maintenance. (Fig. 2-2)
use lug bolts or equal to bolt down unit, reducing
vibration and noise.
if cooling operation is to be used when the outdoor air

Concerning inlet-side distance "C" (Fig. 2-2)
The minimum for distance "C" is 6" if there are no obstructions on the outlet side
CAUTION
(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

If wall *1 is on the outlet side (Fig. 2-2), or if obstructions are present on all 3 sides *2,
*3, and *4 (Fig. 2-2), then the minimum distance for "A" and "B" is 80" (Fig. 2-3). 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"
