Stingl SR-500 SVRS Switch Safety Pool Pump Vacuum Release System

Stingl Safety Vacuum Release System SR-500

The 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 operation and activate an audible alarm (optional). The pump will remain off with the alarm sounding until manually reset.

The Stingl SR-500 monitors vacuum 128 times per second and provides rapid response and accurate readings. In addition to being an effective SVRS system the SR-500 also features a programmable 24 hour timer.

• Pool or Spa SVRS System
• 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 to enable auxiliary equipment can be added
• Power back-up insures settings and reading will be saved (30 minute rapid recharge)
• Display error readout prevents guessing during troubleshooting
• Works on all sizes of pool and spa pumps
• Easy and trouble free installation without any pipes to cut or glue
• Turns off pump in milliseconds upon detecting sudden vacuum change
• Multiple audible alarm capabilities (optional) which allows for quicker alert to harmful situations
• Newest state-of-art NEC microprocessor technology-- guaranteed reliability and performance
• Vacuum monitored 128 times per second for rapid response and accurate readings
• Power monitored 50/60 times per second to insure continuous power detection
• Provides a layer of protection, reducing entrapment risk Complies with ASME/ANSI 112.19.17 as required by the International Building Codes (IBC) and the International Residential Codes (IRC)
• Meets all current codes and standards for SVRSs on new and existing pools and spas
