Stingl SR-500 Safety Vacuum Release System (SVRS)
Monitors vacuum on the suction side of pool or spa pump (vacuum monitored
128 times per second; power monitored 50/60 times per second). When
blockage occurs in main drain or skimmer, a sudden rise in vacuum will cause
the SR-500 to shut down pump operation and activate an audible alarm.
Pump will remain off with alarm sounding until manually reset. Also can act as
pool controller with programmable timer, or as stand alone SVRS working in
conjunction with existing pool controller.
