(Fig. 1-2) use lug bolts or equal to bolt down unit, reducing vibration and noise. if cooling operation is to be used when the outdoor air temperature is 23°F or below, install a duct on the outdoor unit. Hot air Outdoor unit Exhaust fan Heat source Fig. 1-1 Installation space (Obstruction above unit) 1 Distance between obstructions and the unit air inlet and Air direction chamber outlet must be as shown below. (field supply) More than 25/64" *2 *3 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 obstruc- tions on 2 of the remaining 3 sides: *2, *3, *4. If wall *1 is on the outlet side (Fig. 1-2), or if obstructions are present on all 3 sides *2, 4 *3, and *4 (Fig. 1-2), then the minimum distance for "A" and "B" is 80" (Fig. 1-3). 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" beams or equal), a minimum of 6" above ground level to reduce humidity and protect the unit gainst possible water damage and decreased service life. (Fig. 1-4) use lug bolts or equal to bolt down unit, reducing vibration and noise. Anchor bolts (4 pieces) I-89 Fig. 1-4 5 6 SM831148
