• The Vac-Alert Model VA-2000S is a Safety Vacuum Release System (SVRS) designed for submerged suction applications.
• Submerged suction in this case applies to applications where the circulating pump suction is more than 24” below the level of the pool water surface.
• The Model VA-2000S is recommended on commercial pool applications where the pump has a submerged suction of any depth and runs 24/7.
• In submerged suction applications, for pumps 10 horsepower and greater, or for pumps located 10 feet or more below the water line, a pump shut-off switch (Model PSAC) is recommended.
• The Model VA-2000S unit incorporates a 0.375” diameter orifice opening installed below the surge tube section.
• This orifice opening is sized to provide a limited amount of pump start-up surge protection,
  while at the same time allowing enough air into the piping system to insure dissipation of the dynamic suction force caused by the circulating pump.
• The Model VA-2000S SVRS unit also utilizes a check valve assembly equipped with a 0.25 pound spring and a non-vented poppet (no poppet disc or hole through the poppet).
• This check valve assembly utilizes a light duty spring to minimize the sealing force of the check valve.
• The non-vented poppet insures that water from the circulating system, under a positive hydrostatic head condition, does not migrate up into the SVRS unit.
