ACT E10 autocirc®
UNDERSINK PUMP FOR POTABLE WATER SYSTEMS
Energy Efcient • Permanent Magnet Electronically Commutated Motor
The industry’s rst RETROFIT hot water recirculation pump
designed specically for tankless water heater applications,
JUST GOT BETTER with high efciency ECM technology.
Description
ACT E10 autocirc lead-free* pump was designed with highly efficient electronically commutated permanent magnet motor
(ECM/PM technology) specifically for potable water systems. This unique design is perfect for retrofits and systems with tankless
water heaters. No recirculation pipe is required.
Control Mode
The ACT E10 is controlled by a timer and thermostat. A built-in temperature sensor automatically turns the pump ON when
the water temperature in the hot water supply line cools down to 89.6ºF (32ºC). The pump turns OFF automatically when water
temperature reaches 95ºF (35ºC), ensuring instant availability of warm water with hot water only seconds behind. The pump is also
equipped with 24 hour, adjustable timer to provide the most cost effective method of operation. The timer can be programmed
to run only during the time periods when hot water is most frequently required.
