• Condensate pumps are designed to collect condensate and return it to the boiler
• As condensate flows to the receiver tank, it fills with water, the float switch assembly then rises and signals the motor on the pump to start and begin pumping the condensate
• When the float drops with the lower water level and breaks the contact on the switch, the pump will shut off
• This Watchman condensate unit features a corrosion-resistant cast iron receiver with low inlet heights for ease of installation
• The centrifuGallon pump is close-coupled and vertically-mounted with a bronze impeller
• 8000 equivalent direct radiation
