Pump Warnings and Safety Instructions
4
SVRS devices shall only be installed in conjunction with ASME A112.19.8 suction fitting, or a 12 in. x 12
in. (305 mm x 305 mm) drain grate or larger, or an approved channel drain system at each suction outlet
or drain outlet.
• Suction check valves and hydrostatic valves shall not be used with the pump;
• When check valves are installed on the discharge side of the pump a SVRS Check
Valve Kit (P/N 350250Z) must be installed.
IntelliFlo® SVRS PUMP WARNINGS AND SAFETY INSTRUCTIONS
IntelliFlo VS+ SVRS is capable of generating systems pressures up to 50 psi. Installers must ensure that all
system components are rated to withstand at least 50 psi. Over pressurizing the system can result in
catastrophic component failure or property damage.
The presence of a hydrostatic valve in the suction piping has been shown to prolong the high
vacuum present at the drain, even through the drain was protected by an SVRS device.
The Virginia Graeme Baker (VGB) Pool and Spa Safety Act creates new requirements on owners and
operators of commercial swimming pools and spas.
Pools or spas constructed on or after December 19, 2008, shall utilize:
(A) A multiple main drain system without isolation capability with suction outlet covers that meet ASME/ANSI
A112.19.8a Suction Fittings for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs and either:
(i) A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 Manufactured
Safety Vacuum Release Systems (SVRS) for Residential and Commercial Swimming Pool,
Spa, Hot Tub, and Wading Pool Suction Systems and/or ASTM F2387 Standard Specification
for Manufactured Safety Vacuum Release Systems (SVRS) for Swimming Pools, Spas and Hot
Tubs or
(ii) A properly designed and tested suction-limiting vent system or
(iii) An automatic pump shut-off system.
Pools and spas constructed prior to December 19, 2008, with a single submerged suction outlet shall use a suction
outlet cover that meets ASME/ANSI A112.19.8a and either:
(A) A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 and/or ASTM F2387, or
(B) A properly designed and tested suction-limiting vent system, or
(C) An automatic pump shut-off system, or
(D) Disabled submerged outlets, or
(E) Suction outlets shall be reconfigured into return inlets.
The pump is capable of 174 GPM or 104 feet of head; use caution when installing and programming to limit
pumps performance potential with old or questionable equipment.
Never open the inside or the drive motor enclosure. There is a capacitor bank in the SVRS pump that holds
a 230 VAC charge even when there is no power to the unit.
