Stingl's Model SR-500 is a Safety Vacuum Release System (SVRS) which works by monitoring the vacuum on the suction side of the pool or spa pump. When a blockage occurs in the main drain or skimmer, a sudden rise in vacuum will cause the SR-500 to shut down pump operate and activate an audible alarm. The pump will remain off with the alarm sounding until manually reset.

  • Can act as pool controller with programmable timer, or as stand alone SVRS working in conjunction with existing pool controller.
  • Newest state-of-art NEC microprocessor technology—guaranteed reliability and performance.
  • Vacuum monitored 128 times per second—rapid response and accurate readings.
  • Power monitored 50/60 times per second—insures continuous power detection.
  • Can act as a pool and spa controller—with fully programmable 24 hour timer, or as stand alone SVRS working in conjunction with existing pool and spa controller.
  • Integrates with existing timer box (for easy retrofit).
  • Low vacuum sensing (prevents cavitations or running the pump dry—eliminating costly equipment failure).
  • 30 minute maintenance override (for pool or spa service).
  • Accessible extra dry contact—auxiliary equipment can be readily added.
  • Power back-up insures settings and reading will be saved (30 minute rapid recharge).
  • Display error readout (prevents guessing during troubleshooting).
