(Pentair Water Pool and Spa

IMPORTANT SAFETY INSTRUCTIONS

When installing and using this electrical equipment, basic safety precautions should always be
followed, include the following:

READ AND FOLLOW ALL INSTRUCTIONS

To reduce the risk of injury, do not permit children to use this product.

Risk of Electrical Shock. Connect only to a branch circuit protected by a ground-fault
circuit-interrupter (GFCI). Contact a qualifi ed electrician if you cannot verify that the
circuit is protected by a GFCI.

This unit must be connected only to a supply circuit that is protected by a ground-fault
circuit-interrupter (GFCI). Such a GFCI should be provided by the installer and should be
tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt
power. Push the reset button. Power should be restored. If the GFCI fails to operate in this
manner, the GFCI is defective. If the GFCI interrupts power to the pump without the test
button being pushed, a ground current is fl owing, indicating the possibility of an electric
shock. Do not use this pump. Disconnect the pump and have the problem corrected by a
qualifi ed service representative before using.

, Sta-Rite®, and Pentair Pool Products®)

This pump is for use with permanent swimming pools and may also be used with hot tubs
and spas if so marked. Do not use with storable pools. A permanently-installed pool is
constructed in or on the ground or in a building such that it cannot be readily disassembled
for storage. A storable pool is constructed so that it is capable of being readily disassem­bled for storage and reassembled to its original integrity.

General Warnings

• Never open the inside of the drive motor enclosure. There is a capacitor bank that holds a 230
VAC charge even when there is no power to the unit.

• The pump is not submersible.

• The pump is capable of high fl ow rates; use caution when installing and programming to limit
pumps performance potential with old or questionable equipment.

• Code requirements for the electrical connection differ from state to state. Install equipment in
accordance with the National Electrical Code and all applicable local codes and ordinances.

• Before servicing the pump; turn breaker to OFF and disconnect the communication cable, then
switch OFF power to the pump by disconnecting the main circuit to the pump.

• This appliance is not intended for use by persons (including children) of reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning the use of the appliance by a person responsible
for their safety.

• To reduce the risk of injury, do not permit children to use this product.

PUMP WARNING AND SAFETY INSTRUCTIONS

For Pool and Spa Pumps (Non SVRS Pumps)

®

(Pentair Water Pool and Spa

THE USE OF UNAPPROVED COVERS OR ALLOWING USE OF THE POOL OR SPA WHEN COVERS
ARE MISSING, CRACKED OR BROKEN CAN RESULT IN BODY OR LIMB ENTRAPMENT, HAIR EN­TANGLEMENT, BODY ENTRAPMENT, EVISCERATION AND/OR DEATH.

The suction at a pool or spa drain or outlet can cause:

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.

Hair Entanglement: When the hair tangles or knots in the drain cover, trapping the swimmer underwater.
This hazard is present when the fl ow rating of the cover is too small for the pump or pumps.

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 fl ow 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.

, Sta-Rite®, and Pentair Pool Products®)

Mechanical Entrapment: When jewelry, swimsuit, hair decorations, fi nger, 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.

NOTE: ALL SUCTION PLUMBING MUST BE INSTALLED IN ACCORDANCE WITH THE LATEST NA­TIONAL AND LOCAL CODES FOR SWIMMING POOLS, SPAS AND HOT TUBS, INCLUDING NSPI
STANDARDS AND CPSC GUIDELINES.

TO MINIMIZE THE RISK OF INJURY DUE TO SUCTION ENTRAPMENT HAZARD:

• Pools and spas should utilize a minimum of two drains per pump.

• A properly installed and secured ANSI/ASME A112.19.8 approved anti­entrapment suction cover must be used for each drain.

• Each suction cover must be installed at least three (3’) feet apart, as measured
from the nearest point to nearest point.

• Regularly inspect all covers for cracks, damage and advanced weathering.

• If a cover becomes loose, cracked, damaged, broken or is missing, close the
pool or spa immediately, shut off the pump, post a notice and keep the pool or
spa closed until an appropriate certifi ed cover is properly installed.

• Replace drain covers as necessary. Drain covers deteriorate over time due to
exposure to sunlight, pool chemicals and weather.

WhisperFloXF

• Avoid getting hair, limbs or body in close proximity to any suction cover, pool
drain or outlet.

• Disable suction outlets or reconfi gure into return inlets.

A clearly labeled emergency shut-off switch for the pool pump and spa jet pump must
be in an easily accessible, obvious place near the pool or spa. Make sure bathers know
where it is and how to use it in case of emergency.

PUMP WARNING AND SAFETY INSTRUCTIONS

For Pool and Spa Pumps (Non SVRS Pumps)

®

(Pentair Water Pool and Spa

The Virginia Graeme Baker (VGB) Pool and Spa Safety Act creates new requirements for owners and

operators of commercial swimming pools and spas.

Commercial 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 Specifi cation 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.

Commercial 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 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 reconfi gured into return inlets.

, Sta-Rite®, and Pentair Pool Products®)

HAZARDOUS PRESSURE: STAND CLEAR OF PUMP AND FILTER DURING START-UP

Pool and spa circulation systems operate under high pressure. When any part of the circulating system (i.e. locking
ring, pump, fi lter, valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air
can cause the pump housing cover fi lter lid and valves to violently separate which can result in severe personal
injury or death. Filter tank lid and strainer cover must be properly secured to prevent violent separation. Stand
clear of all circulation system equipment when turning on or starting up pump.

Before servicing pool and spa equipment, make note of the fi lter pressure. Be sure that all controls are set to
ensure the system cannot inadvertently start during service. Turn off all power to the pump.

IMPORTANT: Place fi lter manual air relief valve in the open position and wait for all pressure in the
system to be relieved.

Before starting the system, fully open the manual air relief valve and place all system valves in the “open”
position to allow water to fl ow freely from the pool and spa back to the pool or spa. Stand clear of all pool and
spa equipment and start the pump.

IMPORTANT: Do not close fi lter manual air relief valve until all pressure has been discharged from the
valve and a steady stream of water appears. Observe fi lter pressure gauge and be sure it is not higher than

the pre-service condition.

PUMP WARNING AND SAFETY INSTRUCTIONS

For Pool and Spa Pumps (Non SVRS Pumps)

(Pentair Water Pool and Spa

General Installation Information

• All work must be performed by a qualifi ed pool professional, and must conform to all national,
state, and local codes.

• Install to provide drainage of compartment for electrical components.

• These instructions contain information for a variety of pump models and therefore some
instructions may not apply to a specifi c model. All models are intended for use in swimming
pool applications. The pump will function correctly only if it is properly sized to the specifi c
application and properly installed.

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

®

, Sta-Rite®, and Pentair Pool Products®)

The pump can produce high levels of suction within the suction side of the plumbing system.
These high levels of suction can pose a risk if a person comes within the close proximity of
the suction openings. A person can be seriously injured by this high level of vacuum or may
become trapped and drown. It is absolutely critical that the suction plumbing be installed
in accordance with the latest national and local codes for swimming pools.

Electrical controls such as on/off switches, timers, and control systems, etc. should be
properly installed to allow the operation (start-up, shut-down, or servicing) of any pump or
fi lter without requiring the user to place any portion of his/her body over or near the pump
strainer lid or fi lter lid. Such installation should allow the user to stand clear of the fi lter and
pump during system start-up, shut down or servicing of the system.

Two Speed Pump Controls Notice California (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.
