The SVRS Alarm is intended for use in swimming pool
applications and can only be used with The IntelliFlo® VS+ SVRS
and IntelliPro® VS+ SVRS pump.

Most states and local codes regulate the construction, installation, and

operation of public pools and spas, and the construction of residential pools
and spas. It is important to comply with these codes, many of which directly regulate the
installation and use of this product. Consult your local building and health codes for more
information.

IMPORTANT NOTICE - Attention Installer: This Installation and User’s Guide

(“Guide”) contains important information about the installation, operation and safe
use of the SVRS Alarm. This Guide should be given to the owner and/or operator of
this equipment.

Before installing this product, read and follow all warning notices

and instructions in this Guide. Failure to follow warnings and instructions
can result in severe injury, death, or property damage. Call [phone] for additional free
copies of these instructions. Please refer to www.pentairpool.com for more information related
to these products.

Water temperature in excess of 100° F may be hazardous to your health.
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia
occurs when the internal temperature of the body reaches a level several
degrees above normal body temperature of 98.6° F. (37° C.). Effects of
hyperthermia include: (1) Unawareness of impending danger. (2) Failure to
perceive heat. (3) Failure to recognize the need to leave the spa. (4) Physical
inability to exit the spa. (5) Fetal damage in pregnant women. (6)
Unconsciousness resulting in danger of drowning. The use of alcohol, drugs, or
medication can greatly increase the risk of fatal hyperthermia in hot tubs and
spas.
To reduce the risk of injury, do not permit children to use or operate this
product.

When setting up pool water turnovers or flow rates the operator must
consider local codes governing turnover as well as disinfectant feed ratios.

DO NOT increase pump size; this may increase the flow rate through the
system and exceed the maximum flow rate stated on the drain cover. Never

exceed the maximum stated pump flow rating.

If this product is intended for use in other than single-family dwellings, a
clearly labeled emergency switch shall be provided as part of the installation.
The switch shall be readily accessible to the occupants and shall be installed at
least 5 feet (1.52 m) away, adjacent to, and within sight of, the SVRS Alarm.

SVRS Audible Alarm Installation and User’s Guide

WARNINGS AND IMPORTANT SAFETY PRECAUTIONS

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION:

PUMPS REQUIRE HIGH VOLTAGE WHICH CAN SHOCK,
BURN, OR CAUSE DEATH.
BEFORE WORKING ON PUMP!
Always disconnect power to the pool pump at the
circuit breaker from the pump before servicing the
pump. Failure to do so could result in death or
serious injury to service person, pool users or
others due to electric shock.

Before attempting installation or service of the SVRS Alarm, be sure all power
to the circuit supplying AC power is disconnected/switched off at the circuit
breaker. The SVRS Alarm must be installed by a qualified professional.
Grounding (earth bonding) is required to the SVRS Alarm.

Install the pump a minimum of five (5) feet from the inside wall of the pool
and spa. Canadian installations require a minimum of three (3) meters from
pool water.

A pool or spa pump must be installed by a qualified pool and spa

service professional in accordance with the National Electrical Code and all
applicable local codes and ordinances. Improper installation may create an electrical hazard which
could result in death or serious injury to pool users, installers, or others due to electrical shock, and
may also cause damage to property.

iii

Pumps produces high levels of suction, which can pose extreme danger if a

person comes in close proximity to an open pool or spa drain or a loose or
broken drain cover or grate. The pump, when installed according to the manufacturer's
instructions, is designed to help prevent injuries caused by body entrapment in pools. Pumps
does not, however, protect against limb entrapments, disembowelments (when a person sits on a
broken or uncovered pool drain) or hair entanglements.

Pumps improperly sized or installed or used in applications other
than for which the pump was intended can result in serious personal injury or
death. These risks may include but not be limited to electric shock, fire, flooding, suction
entrapment or serious injury or property damage caused by a structural failure of the pump or
other system component.

The IntelliFlo® VS+ SVRS and IntelliPro® VS+ SVRS pump 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.

WARNINGS AND IMPORTANT SAFETY PRECAUTIONS

Two Speed Pump Controls Notice (Title 20 Compliance)

Please read the following important Safety Instructions. When using two-speed pumps
manufactured on or after January 1, 2008, the pump's default circulation speed MUST
be set to the LOWEST SPEED, with a high speed override capability being for a
temporary period not to exceed one normal cycle, or two hours, whichever is less.

SUCTION ENTRAPMENT HAZARD

Pool and spa pumps move large volumes of water, which can pose extreme danger
if a person’s hair comes in close proximity to a drain that is not the proper size for the
pump or pumps.

Hair Entanglement – When the hair tangles or knots in the drain cover, trapping

the swimmer underwater. This hazard is present when the flow rating of the cover
is too small for the pump or pumps.

Limb Entrapment – When a limb is sucked or inserted into an opening resulting in
a mechanical bind or swelling. This hazard is present when a drain cover is
missing, broken, loose, cracked or not properly secured.

Body Entrapment – When a portion of the body is held against the drain cover
trapping the swimmer underwater. This hazard is present when the drain cover is
missing, broken or the cover flow rating is not high enough for the pump or pumps.

Evisceration/Disembowelment – When a person sits on an open pool
(particularly a child wading pool) or spa outlet and suction is applied directly to the
intestines, causing severe intestinal damage. This hazard is present when the drain
cover is missing, loose, cracked, or not properly secured.

Mechanical Entrapment – When jewelry, swimsuit, hair decorations, finger, toe or
knuckle is caught in an opening of an outlet or drain cover. This hazard is present
when the drain cover is missing, broken, loose, cracked, or not properly secured.

Two Speed Pump Controls Notice (Title 20 Compliance)

Please read the following important Safety Instructions. When using two-speed
pumps manufactured on or after January 1, 2008, the pump's default circulation

SVRS Audible Alarm Installation and User’s Guide

Section 1

Safety Vacuum Release System (SVRS) Audible Alarm
Overview

The Safety Vacuum Release System (SVRS) audible alarm device is designed to
be used with an IntelliFlo® VS+ SVRS pump or IntelliPro® VS+ SVRS pump.
The pump is connected to the SVRS audible alarm circuit board via a 50 ft.
two-conductor cable. The pump complies with the ASME/ANSI A112.19.17­2002 SVRS standard which defines how fast the pump must stop on a suction
blockage event. The SVRS audible alarm activates the alarm if the pump stops
due to an SVRS blockage event on the main pool or spa suction outlet drain
cover(s).

Emergency Shut-Off Switch (ESO3) Accessory

If an Emergency Shut-Off Switch (ESO3) is connected to the SVRS Alarm
power center and an SVRS blockage event occurs, the SVRS audible alarm will
activate but the ESO3 alarm will not sound. Pressing the ESO3 button will switch
OFF AC power to the pump and activate both alarms.

IntelliFlo SVRS Pump Operation Modes

The SVRS Audible Alarm supports two pump operation modes; “SCHEDULE”
and “MANUAL.”

1

Schedule mode (see page 7): Each of the pump’s four speed buttons can be

scheduled for start/stop times and run speeds.

Important notes when scheduling pump start and stop times:

• To schedule the pump to run for 24 hours per day without
turning off, requires two (2) separate schedules; for example
set Speed 1 in the pump’s “Schedule Mode” to start at 8 AM
and stop at 7:59 AM and Speed 2 to start at 7:57 AM and stop
at 8:01 AM.

Note: It is not recommended to program a speed button to
run one schedule for 23 hours and 59 minutes (23:59) per
day. Program a second schedule to overlap the first
program. Refer to the example described above.

• For more information about programming the pump,
see page 12.

IntelliFlo Pump Control Panel Buttons and Display Message

While the SVRS Audible Alarm is active and communicating with the IntelliFlo
VS+ SVRS or IntelliPro VS+ SVRS pump, the pump control panel displays
“Display Not Active” and the pump control buttons are disabled.

SVRS Audible Alarm Installation and User’s Guide

IntelliFlo VS+ SVRS and IntelliPro VS+ SVRS Pump Overview

The IntelliFlo VS+ SVRS and IntelliPro VS+ SVRS variable speed pump with the
safety vacuum release system (SVRS) protection feature operates at a maximum
system flow rate of up to 174 gallons per minute (GPM). 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 pump’s 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.
The IntelliFlo VS+ SVRS and IntelliPro VS+ SVRS 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.

Note: 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.
