Evaporator Heaters (Optional)
Test the resistance of each evaporator heater by disconnecting it from the circuit and checking it with an ohmmeter. The
resistance of each evaporator heater should be approximately 71 ohms.
Condenser Fan Rotation
The condenser fan is belt driven. On electric standby operation, check for correct fan rotation by placing a small cloth or sheet
of paper against the condenser fan grille on the front of the unit. Correct rotation will hold the cloth or paper against the grille.
Improper rotation will blow the cloth or paper away from the grille. To correct incorrect rotation, check the motor and motor
contactor wiring per the unit wiring diagram.
Phase Select Module for Truck Unit Model 50 Applications
The phase select module is designed to monitor both single and 3 phase nominal input voltages between 200 and 480 volts AC.
