NOTES:
Heat kit is an optional part, and it must have a separate power supply.
It is recommended that the electric heater kit should be installed in cold climate regions or when long piping
is used. Properly size the axillary heater per the table above.
Ampacities for MCA and Fuse/breaker include the blower motor.
Heat pump systems require a specified airflow. Each ton of cooling requires between 350 and 450 cubic feet
of air per minute(CFM).
