T3NM : Motor Temperature Cutback

To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.

Cooling fan on back of motor not operating properly

Ensure fan is always running when machine is powered on
Ensure fan is blowing air toward the motor (inward)
Ensure fan is clean and moves freely. Remove any obstructions in front of fan grille.
Ensure no hot air (from other heat sources) is being directed toward the fan.

Ambient temperature is too high

Ensure system ambient temperature is below 120F (48C).

Machine is operating above pressure/flow rating

Mix chamber is too large for set pressure
Set pressure is too high for given mix chamber

This cutback occurs to preserve motor life. If the motor gets too hot this advisory automatically reduces the pressure setpoint to allow the motor to cool. To avoid this advisory, run the system at a lower duty cycle or with a smaller mix chamber.
