Selecting the Installation Site for Outdoor UnitAVOID:heat sources, exhaust fans, etc.(Fig.2-6)damp, humid or uneven locationsDO:choose a place as cool as possible.choose a place that is well ventilated and outsideair temperature does not exceed maximum 113°Fconstantly.allow enough room around the unit for air intake/exhaust and possible maintenance.(Fig.2-7)use lug bolts or equal to bolt down unit, reducingvibration and noise.Installation spaceDistance between obstructions and the unit air inletand outlet must be as shown below.Fig. 2-6Fig. 2-8Out-doorunitHeat sourceHot airExhaust fanAnchor bolts(4 pieces)In case of multiple installationsprovide a solid base (concrete block, 4 × 16 in.beams or equal), a minimum of 6 in. above groundlevel to reduce humidity and protect the unit againstpossible water damage and decreased service life.(Fig. 2-9)use lug bolts or equal to bolt down unit, reducingvibration and noise.CAUTION Concerning inlet-side distance “C” (Fig. 2-7)The minimum for distance “C” is 6 in. 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 in.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. 2-7), or if obstructions are present on all 3 sides *2,*3, and *4 (Fig. 2-7), then the minimum distance for “A” and “B” is 6.6 ft. (Fig. 2-9).Even if there is no wall on the outlet side, a minimum of 3.3 ft. is required.Fig. 2-7Fig. 2-9
