Stingl Switch (Safety Vacuum Release System)
| The SR-500 ( for a single body of
water ) 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 bottom drain or skimmer a rise in vacuum will cause the
SR-500 to shut the pump operation and activate an audible alarm. The pump
will remain off with the alarm sounding until manually reset. |

Features and Benefits
- 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
- 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 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 size pumps
- Easy and trouble free installation - (no pipes to cut or glue)
- Turns off pump in milliseconds upon detecting sudden vacuum change
- Multiple audible alarm capabilities allows for quicker alert to
harmful situations
- Provides a layer of protection, reducing entrapment risk

A couple of things to note are the following:
No Check Valves can be used in the system.
ALL check valves must be removed from the influent and effluent sides
of the filtration system. Check valves, in conjunction with the SVRS,
can cause residual vacuum to remain on a line in an entrapment situation.
It is important that all check valves be removed from the system before
installation of the SR-500.
No Spring Loaded Hydrostatic Relief Valves in Main Drain Sumps
Spring-loaded hydrostatic relief valves must be removed and replaced with
solid plugs. A spring-loaded check valve in the main drain sump can interfere
with operations for the SR-500. In an entrapment situation, the spring-loaded
check valve can open, causing the SR-500 to trip later than normal, or
not at all.
