(Fig. 1-6) use lug bolts or equal to bolt down unit, reducing vibration and noise. if cooling operation is to be used when the outdoor air temperature is 23°F or below, install a duct on the outdoor unit. 1 Installation space Distance between obstructions and the unit air inlet and outlet must be as shown below. *3 More than 1/2" *2 Inlet side C Outlet side More than 3.3 ft.

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. 1-6), or if obstructions are present on all 3 sides *2, *3, and *4 (Fig. 1-6), then the minimum distance for "A" and "B" is 80" (Fig. 1-7). 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.
