This signal is used by the controller to control the flow of refrigerant into the evaporator for optimal and energy efficient
performance. The liquid level sensor will be calibrated and located on the evaporator upon dispatch of the unit. However
in the following section there is a quick guide on how to reset and recalibrate the sensor.
