Pump Overview
The IntelliFlo
®
VS+SVRS or IntelliPro
®
VS+SVRS Variable Speed Pumps with the safety vacuum
release system (SVRS) protection feature is well suited for all of your pool, spa, waterfall and other
applications. The functionality of the IntelliFlo VS+SVRS or IntelliPro VS+SVRS pump is identical
except for the pump’s external color. The IntelliFlo VS+SVRS pump’s exterior case is almond color and
the IntelliPro VS+SVRS pump exterior case is black. The pump can use up to eight (8) speeds which can
be adjusted to run at specific speeds and time intervals. The pump out performs all conventional pumps
in its class. Advanced energy conservation features ensure that your filtration system is operating at peak
efficiency.
The 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 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 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.
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 pump can communicate with an IntelliTouch
®
, EasyTouch
®
, or SunTouch
®
Control System or
the IntelliComm
®
Communication Center via a two-wire RS-485 cable provided with the pump.
EasyTouch and SunTouch control systems can remotely control the pump’s four preset speeds. The
IntelliTouch control 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.
