a specific high-altitude pressure switch (such as the 193811) is required to account for lower air density

Rugged Construction: Designed to resist environmental factors like moisture and dust

System Performance: Restores factory-spec airflow distribution across the heat exchanger

the protective coating and structural integrity of the water level sensor degrade over time

Versatile Range: Adjustable setpoint from 0
