WARNING
PROPOSITION 65:
This appliance con-
tains fiberglass insulation. Respi-
rable particles of fiberglass are
known to the State of California to
cause cancer.
All manufacturer products meet
current Federal
OSHA
Guidelines for
safety. California Proposition 65
warnings are required for certain
products, which are not covered by
the
OSHA
standards.
California’s Proposition 65 requires
warnings for products sold in Cali-
fornia that contain or produce any
of over 600 listed chemicals known
to the State of California to cause
cancer or birth defects such as
fiberglass insulation, lead in brass,
and combustion products from nat-
ural gas.
All “new equipment” shipped for
sale in California will have labels
stating that the product contains
and/or produces Proposition 65
chemicals. Although we have not
changed our processes, having the
same label on all our products facil-
itates manufacturing and shipping.
We cannot always know “when, or
if” products will be sold in the Cali-
fornia market.
You may receive inquiries from
customers about chemicals found
in, or produced by, some of our
heating and air-conditioning equip-
ment, or found in natural gas used
with some of our products. Listed
below are those chemicals and sub-
stances commonly associated with
similar equipment in our industry
and other manufacturers.
• Glass Wool (Fiberglass) Insulation
• Carbon Monoxide (CO)
• Formaldehyde
• Benzene

. Consumer educa-
tion is important since the chem-
icals and substances on the list
are found in our daily lives. Most
consumers are aware that products
present safety and health risks,
when improperly used, handled and
maintained.
NOTICE
When used in cooling applications, excessive sweating may occur when unit
is installed in an unconditioned space. This can result in property damage.
NOTICE
Improper installation, or installation not made in accordance with the Under-
writers Laboratory (UL) certification or these instructions, can result in unsat
-
isfactory operation and/or dangerous conditions and are not covered by the
unit warranty.
NOTICE
Use of this air-handler during construction is not recommended. If operation
during construction is absolutely required, the following temporary installation
requirements must be followed:
Installation must comply with all Installation Instructions in this manual includ-
ing the following items:
• Properly sized power supply and circuit breaker/fuse
• Air-handler operating under thermostatic control;
• Return air duct sealed to the air-handler;
• Air filters must be in place;
• Correct air-flow setting for application
• Clean air-handler, duct work, and components including coil upon comple
-
tion of the construction process and verify proper air-handler operating con-
ditions according as stated in this instruction manual.
• NOTE: Electric strip heater elements tend to emit a burning odor for a few
days if dust has accumulated during construction. Heater elements are easi-
ly damaged. Take great care when cleaning them. Low pressure compressed
air is recommended for cleaning elements.
WARNING
Duct leaks can create an unbalanced system and draw pollutants such as dirt,
dust, fumes and odors into the building causing property damage. Fumes
and odors from toxic, volatile or flammable chemicals, as well as automo
-
bile exhaust and carbon monoxide (CO), can be drawn into the living space
through leaking ducts and unbalanced duct systems causing personal injury
or death (see Figure 1).
• If air-moving equipment or ductwork is located in garages or off-garage stor
-
age areas – all joints, seams, and openings in the equipment and duct must
be sealed to limit the migration of toxic fumes and odors including carbon
monoxide from migrating into the occupied space.
• If air-moving equipment or ductwork is located in spaces containing fuel
burning appliances such as water heaters or boilers – all joints, seams, and
openings in the equipment and duct must also be sealed to prevent depres-
surization of the space and possible migration of combustion byproducts
including carbon monoxide into the occupied space.
