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

Stingl Safety Vacuum Release System SR-500The 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 User Manual
