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.
NOTICE !
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.

IMPORTANT !
This model is designed for use in check / expansion
valve systems only. An indoor expansion valve ap­
proved for use with HFC-410A refrigerant must be or­
dered separately and installed prior to operating the
system.
IMPORTANT !
Exhaust vents from dryers, water heaters and furnaces
should be directed away from the outdoor unit. Pro­
longed exposure to exhaust gases and the chemicals
contained within them may cause condensation to
form on the steel cabinet and other metal components
of the outdoor unit. This will diminish unit performance
and longevity.
INSTALL UNIT AWAY
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.
