NOTICE!
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roong material may absorb oil, causing the
rubber to degrade. Failure to follow this notice could
result in damage to roof surface.
IMPORTANT
This unit must be matched with an indoor coil as specied
with AHRI. For AHRI Certied system match-ups and
expanded ratings, visit www.LennoxPros.com. Coils
previously charged with HCFC-22 must be ushed.
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.
IMPORTANT
The Clean Air Act of 1990 bans the intentional venting of
refrigerant (CFCs, HCFCs and HFCs) as of July 1, 1992.
Approved methods of recovery, recycling or reclaiming
must be followed. Fines and/or incarceration may be
levied for noncompliance.
IMPORTANT
Exhaust vents from dryers, water heaters and furnaces
should be directed away from the outdoor unit. Prolonged
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
