1.0 SAFETY INFORMATION WARNING Duct leaks can create an unbalanced system and draw pollutants such as dirt, dust, fumes and odors into the home causing property damage. Fumes and odors from toxic, volatile or flammable chemicals, as well as automobile 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). - Page 4 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.

Page 48: Blower Motor & Wheel
13.4 BLOWER MOTOR AND WHEEL Inspect the blower motor and wheel for cleanliness. With the system air filter in place, it should be several years before it would become necessary to clean the blower motor and wheel. • If it becomes necessary to remove the blower assembly from the unit, see instruc- tions on removal and disassembly of motor, blower and heater parts. -

FIGURE 39 INTERNAL MOTOR PLUG AND SOCKET • Loosen the bolt holding the wire motor band around the motor shell and pull the motor from the motor mount. Note the motor position in the mount for re-assembly. • To re-assemble, insert the motor shaft through the hub in the blower wheel and orient the motor to original position. - Page 50 WARNING Always have 240 volt power turned off to the furnace before attempting any replacement of the motor or control module. Failure to do so may result in seri- ous equipment damage, personal injury or death. 3. While not necessary, it may prove easier to remove the complete blower assembly from the furnace.
