IntelliFlo VS+ SVRS Variable Speed Pump
The IntelliFlo VS+ SVRS variable speed pump with the safety vacuum release system (SVRS) protection is
well suited for all of your pool, spa, waterfall and other applications. The IntelliFlo VS+ SVRS can use up
to eight (8) speeds which can be adjusted to run at specific speeds and time intervals. IntelliFlo out
performs all conventional pumps in its class. Advanced energy conservation features ensure that your
filtration system is operating at peak efficiency.
The IntelliFlo pump operates at a maximum system flow rate of up to 174 gallons per minute (GPM).
System setup for the SVRS requires that the suction vacuum level be adjusted to 25" of mercury (Hg) or
less at the pump strainer housing connection.
The IntelliFlo VS+ SVRS pump can operate from 1100 RPM to 3450 RPM with preset speeds of 1100,
1500, 2350 and 3110 RPM. The pump can be adjusted from the control panel to run at any speed
between 1100 RPM to 3450 RPM for different applications. The IntelliFlo pump control panel alarm LED
and error messages warn the user against under and over voltage, high temperature, over current, suction
blockage and freeze protection with user defined minimum and maximum speed presets. See page 39 for
additional information.
This pump is intended to be used as part of a complete pool safety system. It complies with the ASME/
ANSI A112.19.17-2002 SVRS standard which defines how fast the pump must stop on a suction blockage
event. This pump may not protect individuals from hair entrapment, limb entrapment or evisceration. The
operator must ensure that all suction and return fittings are clean and unobstructed whenever the pump is
started. Because SVRS protection is not enabled during priming mode, never allow anyone in the
pool during priming mode.
If SVRS auto restart is enabled and an SVRS event occurs, the pump is allowed to restart automatically
after the preset time period. The operator must insure that any SVRS blockage event is quickly
evaluated to confirm that all suction and return fittings are clean and unobstructed. When the pump
restarts after a high vacuum event it will slowly ramp up to speed. If the pump senses a blockage it will shut
down. The pump will attempt to soft prime 10 times before attempting a full prime.

Remote Control

The IntelliFlo VS+ SVRS can communicate with an
IntelliTouch ® , EasyTouch
®
IntelliComm communication center via a two-wire RS-485
cable provided with the pump. EasyTouch and IntelliComm
can remotely control the IntelliFlo VS+ SVRS four preset
speeds. The IntelliTouch system can be configured to control a
total of eight speeds. The pump's address and other pump
functions are accessed from the pump's control panel.
