If roof curb is not used, support unit with steel beams along its entire length and then support steel as required. As a mini- mum, unit must be supported across its width at each lifting lug location.

Positioning Ð Provide clearance around and above unit for air¯ow, safety, and service access. Do not restrict top (area above condenser fans) in any way. Allow at least 6 ft on all sides for rated performance, code compliance, and service.

Do not install unit in an indoor location. Do not locate air inlets near exhaust vents or other sources of contaminated air.

On units equipped with or power exhaust option, high ve- locity air is exhausted out the hoods. Unit should be posi- tioned with at least 10 ft clearance between the exhaust hoods and any obstruction. Although unit is weatherproof, guard against water from higher level runoff and overhangs.
