Blower Speed

For optimum system performance and comfort, it may be 

necessary to change the factory speed setting. See 

Table 

1

 below for factory settings. 

NOTE

: This model has a High 

Efficiency ECM Motor with 5 speed taps.

 WARNING:

To avoid electric shock, personal injury, or death, 

turn off the electric power at the disconnect or the 

main service panel before making any electrical 

connections.

1.  Disconnect all electrical power to the unit and remove 

the service panel.

 CAUTION:

Label all wires prior to disconnection when 

servicing controls. Wiring errors can cause 

improper and dangerous operation. Verify proper 

operation after servicing.

2.  Locate the orange, black and blue wires terminated to 

the blower motor. The black wire controls the low speed 
cooling and heating operations, the blue wire controls 
high speed cooling and heating operations and the 
orange wire controls the electric heating operation.

 CAUTION:

To avoid personal injury or property damage, 

make certain that the motor leads cannot come 

into contact with any metal components of the 

unit.

3.  Verify the required speed from the airflow data found 

in 

Table 1

. Place appropriate wire on the appropriate 

motor speed tap for the required airflow.

4.  Check all factory wiring per the unit wiring diagram and 

inspect the factory wiring connections to be sure none 
loosened during shipping or installation.

2-Speed Outdoor Fan Motor
(Select Models)

If the unit utilizes a 2-speed condenser fan motor, this 

motor will operate on low speed when in low cooling/

heating, and on high speed when in high cooling/heating.

Ambient Sensor Mounting

For optimum performance of the heat pump system, the 
ambient sensor (

Figure 6 (page 9)

) must be mounted 

on the outside of the unit.
1.  Remove the mounting bracket and all hardware included 

in the packet.

2.  Remove star bushing from 7/8” hole in corner panel of 

the unit.
