 Centrifugal Pump Installation and User’s Guide

IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS

When installing and using this electrical equipment, basic safety 

precautions should always be followed, include the following:

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 qualified 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 flowing, indicating the possibility of an 

electric shock. Do not use this pump. Disconnect the pump and have the 

problem corrected by a qualified service representative before using.

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 flow rates; use caution when installing 

and programming to limit pumps performance potential with old or 

questionable equipment.

•  Code requirements for electrical connection differ from country to 

country, state to state, as well as local municipalities. Install equipment 

in accordance with the National Electrical Code and all applicable 

local codes and ordinances.

•  Before servicing the pump; 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.

FAILURE TO FOLLOW ALL INSTRUCTIONS AND 

WARNINGS CAN RESULT IN SERIOUS BODILY 

INJURY OR DEATH. 

THIS PUMP SHOULD BE INSTALLED AND 

SERVICED ONLY BY A QUALIFIED POOL SERVICE PROFESSIONAL. 

INSTALLERS, POOL OPERATORS AND OWNERS MUST READ THESE 

WARNINGS AND ALL INSTRUCTIONS IN THE OWNER’S MANUAL 

BEFORE USING THIS PUMP. THESE WARNINGS AND THE OWNER’S 

MANUAL MUST BE LEFT WITH THE POOL OWNER.

SUCTION ENTRAPMENT HAZARD: STAY OFF 

THE MAIN DRAIN AND AWAY FROM ALL SUCTION 

OUTLETS!

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 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 flow 

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 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.

THIS PUMP PRODUCES HIGH LEVELS OF SUCTION AND CREATES 

A STRONG VACUUM AT THE MAIN DRAIN AT THE BOTTOM OF THE 

BODY OF WATER. THIS SUCTION IS SO STRONG THAT IT CAN TRAP 

ADULTS OR CHILDREN UNDER WATER IF THEY COME IN CLOSE 

PROXIMITY TO A DRAIN OR A LOOSE OR BROKEN DRAIN COVER 

OR GRATE.

This guide provides installation and operation instructions for this pump. 

Consult Pentair with any questions regarding this equipment. 

Attention Installer: 

This guide contains important information about the 

installation, operation and safe use of this product. This information should 

be given to the owner and/or operator of this equipment after installation 

or left on or near the pump. 

Attention User: 

This manual contains important information that will help 

you in operating and maintaining this product. Please retain it for future 

reference.
