Xylem-McDonnell & Miller 311200 Replacement Float 21-30

The Xylem-McDonnell & Miller 311200 21-30 is a substitute float for an assortment of HVAC equipment, notably condensate tanks. A condensate tank is an HVAC system component that acquires water vapour when it condenses from the air. The float is a buoyant gadget that rises and reduces with the amount of liquid in the tank. As the water level increases, the float triggers a switch that shifts off the humidification system or the condensate pump, avoiding the tank from overflow. When the water level decreases, the float triggers the switch, switching the humidifier back on or resuming the condensate pump. A faulty float may lead to difficulties that include overflowing tanks or pump difficulties.
