Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil, causing the
rubber to degrade. Failure to follow this notice could
result in damage to roof surface.
Exhaust vents from dryers, water heaters and fur
naces should be directed away from the outdoor unit.
Prolonged exposure to exhaust gases and the chemi
cals contained within them may cause condensation
to form on the steel cabinet and other metal compo
nents of the outdoor unit. This will diminish unit per
formance and longevity.
Install unit level or, if on a slope, maintain slope tolerance of 2
degrees (or 2 inches per 5 feet [50 mm per 1.5 m]) away from
building structure.
