On rooftop applications, locate unit at least 6 in. above roof
surface.
Step 4_Operating Ambient
The minimum outdoor operating ambient in cooling mode is 55°F,
and the maxinmm outdoor operating ambient in cooling mode is
125°F.
Step 5--Elevate Unit
Accumulation of water and ice in base pan may cause
equipment damage.
Elevate unit per local climate and code requirements to provide
clearance above estimated snowfall level and ensure adequate
drainage of the unit. Fig. 4 shows unit with accessory support feet
installed. Use accessory snow stand in areas where prolonged
freezing temperatures are encountered. Refer to separate Installa-
tion Instructions packaged with accessories.
Do not allow POE lubricant to come into contact with roofing
material. POE may deteriorate certain types of synthetic
roofing.
NOTE: Unit must be level to within ±2 ° (±3/8 in.ift).
Step 3--Clearance Requirements
When installing, allow sufficient space fbr airflow clearance,
wiring, refrigerant piping, and service. Allow 30-in. clearance to
service end of unit and 48 in. above unit. For proper airflow, a 6-in.
clearance on 1 side of unit and 12 in. on all remaining sides nmst
be maintained. Maintain a distance of 24 in. between units.
Position so water, snow, or ice from roof or eaves cannot Pall
directly on unit.
