Recognize this symbol as an indication of Important Safety Information!

IMPORTANT: 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 produced by, some of our heating and air-conditioning

equipment, or found in natural 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 present safety and health risks, when improperly used, handled and maintained.
