triponit’sinternaltemperaturelimitandmaycauseunitdamage.Whenthe
temperature limit trips, the compressor must be allowed to cool before it will
restart. Thermal overload cooling and reset may take substantial time.
7. Procedure to set proper rotation:
a. Supply electrical power to the unit. Once the correct voltage is supplied
to the unit, the control instrument will read "Standby" or "Status Ready".
Adjust the setpoint to 70°F or higher to prevent the compressor from
activating during this procedure. See Section 3.5 for additional details.
b. Remove all necessary cover panels to access the pump motor.
