AMTC HYBRIDFLUSH HSM-801 Series User manual

User Approaches Senses User Flushes When
User Leaves
®
The HYBRIDFLUSH sends out an infrared beam that senses a user on a urinal or toilet. Once the user walks away from the
fixture the unit triggers the fixture to flush automatically. The unit’s unique design includes two manual flush buttons (one electronic
and one mechanical) to allow for a courtesy manual flush option and for continuous manual activation when batteries are drained.
