AIR CONDITIONING

This furnace may be used as part of an air conditioning system. The furnace wiring and control system is "air
conditioning ready." There are the following factors to consider:
IOM
The air conditioning evaporator coil must be downstream of the heat exchanger. The cooled air passing
over the warmer heat exchanger tubes can cause condensation inside the tubes, resulting in corrosion and
premature failure.
A parallel duct system can be installed to direct the air from the furnace through the evaporator coil only. Use
dampers or other means to bypass the heat exchanger. If (summer/winter) dampers are used, they should be
interlocked to prevent system operation unless the dampers are in the full open or full closed position.
