PROPOSITION 65: This appliance contains fiberglass insulation. Respirable particles of 

fiberglass are known to 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 only have labels stating that the product 

contains and /or produces Proposition 65 chemicals. We cannot always know “when, or if” 

products will be sold in the California market, thus all products may not be labeled when their 

final destination is unknown.
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).

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.

Make sure the blower motor support is tight (3-motor 

mount bolts) then check to see if wheel is secured to 

motor shaft before operating unit. To avoid electrical 

shock, which can result in injury or death, use only the 

screws furnished with the motor from the manufacturer.
