WARNING

(SEE SECTION 13.5: BLOWER ASSEMBLY REMOVAL & REPLACEMENT)

If removal of the blower assembly is required, all disconnect switches supply-
ing power to the airhandler must be de-energized and locked (if not in sight of
unit) so the field power wires can be safely removed from the blower assem-
bly. Failure to do so can cause electrical shock resulting in personal injury or
death.

!

WARNING

PROPOSITION 65: This appliance contains fiberglass insulation. Respirable
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 California
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 natural 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
facilitates manufacturing and shipping. We cannot always know “when, or if”
products will be sold in the California market.

You may receive inquiries from customers about chemicals found in, or pro-
duced by, some of our heating and air-conditioning equipment, or found in nat-
ural gas used with some of our products. Listed below are those chemicals and
substances commonly associated with similar equipment in our industry and
other manufacturers.

• Glass Wool (Fiberglass) Insulation
• Carbon Monoxide (CO).
• Formaldehyde
• Benzene

More details are available at the websites for OSHA (Occupational Safety and
Health Administration), at www.osha.gov and the State of California’s OEHHA
(Office of Environmental Health Hazard Assessment), at www.oehha.org.
Consumer education is important since the chemicals and substances on the
list are found in our daily lives. Most consumers are aware that products pre-
sent safety and health risks, when improperly used, handled and maintained.

!

WARNING

(SEE SECTION 6.0: DUCTWORK)

Do not, under any circumstances, connect return ductwork to any other heat
producing device such as fireplace insert, stove, etc. Unauthorized use of
such devices may result in fire, carbon monoxide poisoning, explosion, per-
sonal injury or property damage.

!

WARNING

Because of possible damage to equipment or personal injury, installation, ser-
vice, and maintenance should be performed by trained, qualified service per-
sonnel. Consumer service is recommended only for filter cleaning/replace-
ment. Never operate the unit with the access panels removed.

!

WARNING

(SEE SECTION 13.0: MAINTENANCE)

Units with circuit breaker(s) meet requirements as a service disconnect
switch, however, if access is required to the line side (covered) of the circuit
breaker, this side of the breaker(s) will be energized with the breaker(s) de-
energized. Contact with the line side can cause electrical shock resulting in
personal injury or death.

!

WARNING

(SEE SECTION 4.3: GROUNDING)

The unit must be permanently grounded. Failure to do so can result in electri-
cal shock causing personal injury or death.
