NOTE:

If nominal CFM is 1000 (2.5 tons) with 15 kW electric heat, the motor speed must be set at medium or higher.
Maximum kW for units with nominal CFM set at 1400 (3.5 tons) is 15 kW.
For 208 volt use .751 correction factor for kW and Btuh.
15 and 20 kW (2 stage models) require 2 supply circuits.
Circuit #1 includes blower motor amps.
kW packages in bold indicate that these packages require and include circuite breakers. Optional for others.

Adjust tap (+) will increase airflow by 10%, while tap (-) will decrease airflow by 12%
Adjust tap test will cause the motor to run at 70% of full airflow. Use this for troubleshooting only.
At the start of a call for cooling, there is a blower delay of 1 minute.
