STEP 1 -- SETTING THE UNIT

(CONTINUED) -- Unit Placement
CAUTION
Before attempting to perform any service or maintenance,
turn the electrical power to unit OFF at disconnect switch.
CAUTION
As with any mechanical equipment, contact with sharp
sheet metal edges can result in personal injury. Take care
while handling this equipment and wear gloves and pro­
tective clothing.
WARNING
To prevent personal injury, as well as damage to panels,
unit or structure, observe the following:
While installing or servicing this unit, carefully stow all
removed panels so that the panels will not cause injury
to personnel, objects or nearby structures. Also, take
care to store panels where they will not be subject to
damage (e.g., being bent or scratched).
While handling or stowing the panels, consider any
weather conditions (especially wind) that may cause
panels to be blown around and damaged.

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.
