Model # SR500PS
SR-500 PS Pool/Spa Combination Stingl Switch (Safety Vacuum Release System)
The Model SR-500PS is specifically designed for Residential Pool/Spa combinations that share one common pump, and still provides the same reliable vacuum entrapment detection capabilities as the Model SR-500 Stingl Switch.
The SR-500PS is equipped with 2 “New Features"
2 Vacuum memory settings - one for the pool, and one for the spa
Features and Benefits:
When the system is hooked up, will a change in pressure such as hooking up a vacuum line, leaves in skimmer basket, etc shut the pump off?

The Stingl Switch SR500 monitors the vacuum on the influent side of the pool or spa pump. Whenever a blockage occurs in the pool drain or skimmers, the sudden rise in vacuum will cause the Stingl Switch to immediately shut down the pump and activate an audible alarm. The pump will remain off and the alarm will sound until manually reset. The Stingl Switch provides a 30-minute Maintenance/Cleaning mode to allow pool vacuuming. Normally, the high vacuum generated by pool vacuuming would cause it to sense an entrapment condition and shut off the pump. However, in Maintenance/Cleaning mode, the switch is deactivated and the pump is allowed to run under a high vacuum situation.

If I install this switch, do I still need an emergency shutoff out by the pool?

An emergency shutoff is not required once there is a safety vacuum release system installed. However, different parts of the country have different codes so you should double check what is required by your local code.
