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.

Do not permit children to use this product.

RISK OF ELECTRICAL SHOCK. Connect only to a branch circuit protected by a ground-fault circuitinterrupter (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 or 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.

SUCTION ENTRAPMENT HAZARD: STAY OFF

THE MAIN DRAIN AND AWAY FROM ALL SUCTION OUTLETS! THIS PUMP IS NOT EQUIPPED WITH SAFETY VACUUM

RELEASE SYSTEM (SVRS) PROTECTION AND DOES NOT PROTECT AGAINST BODY OR LIMB ENTRAPMENTS, DISEMBOWELMENTS (WHEN A PERSON SITS ON A BROKEN OR UNCOVERED POOL DRAIN) OR HAIR ENTANGLEMENTS.

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.

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.

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.

IMPORTANT WARNING AND SAFETY INSTRUCTIONS

TO MINIMIZE THE RISK OF INJURY DUE TO

SUCTION ENTRAPMENT HAZARD:

•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, replace with an appropriate certified cover.

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

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

•Disable suction outlets or reconfigure into return inlets.

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.

A clearly labeled emergency shut-off switch for the pump must be in an easily accessible, obvious place. Make

sure users know where it is and how to use it in case of emergency.

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 Specification 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 reconfigured into return inlets.

For Installation of Electrical Controls at Equipment

Pad (ON/OFF Switches, Timers and Automation Load Center)

Install all electrical controls at equipment pad, such as

on/off switches, timers, and control systems, etc. to allow

the operation (startup, shut-down, or servicing) of any pump or filter so the user does not place any portion of his/her body over or near the pump strainer lid, filter lid or valve closures.

This installation should allow the user enough space to stand clear of the filter and pump during system start-up, shut down or servicing of the system filter.

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

Circulation systems operate under high pressure. When

any part of the circulating system (i.e. locking ring, pump,

filter, valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the pump housing cover, filter 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 equipment, make note of the filter 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 filter 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 flow freely from the tank and back to the tank. Stand clear of all equipment and start the pump.

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

General Installation Information

INSTALLATION

Only a qualified plumbing professional should install the pump. Refer to IMPORTANT WARNING AND SAFETY INSTRUCTIONS on page i-ii for additional installation and safety information.

Location

Note: Do not install this pump within an outer enclosure or beneath the skirt of a hot tub or spa unless marked accordingly.

Note: Ensure that the pump is mechanically secured to the equipment pad.

Be sure the pump location meets the following requirements:

1.Install the pump as close to the pool or spa as possible. To reduce friction loss and improve efficiency, use short, direct suction and return piping.

2.Install a minimum of 5' (1.5 m) from the inside wall of the pool and spa. Canadian installations require a minimum of 9.8' (3 m) from the inside wall of the pool.

3.Install the pump a minimum of 3' (0.9 m) from the heater outlet.

4.Do not install the pump more than 10' (3.1 m) above the water level.

5.Install the pump in a well ventilated location protected from excess moisture (i.e. rain gutter downspouts, sprinklers, etc.).

Figure 2

5 x SUCTION PIPE DIAMETER

ELBOW

6.Install the pump with a rear clearance of at least

3" (7.6 cm) so that the motor can be removed easily for maintenance and repair. See Figure 1.

Piping

1.For improved pool plumbing, it is recommended to use a larger pipe size.

2.Piping on the suction side of the pump should be the same or larger than the return line diameter.

3.Plumbing on the suction side of the pump should be as short as possible.

4.For most installations Pentair recommends installing a valve on both the pump suction and return lines so that the pump can be isolated during routine maintenance. However, we also recommend that a

valve, elbow or tee installed in the suction line should be no closer to the front of the pump than five (5) times the suction line diameter. See Figure 2.

Example: A 2.5" pipe requires a 12.5" (31.8 cm) straight run in front of the suction inlet of the pump. This will help the pump prime faster and last longer.

Note: DO NOT install 90° elbows directly into the pump inlet or outlet.

Fittings and Valves

1.Do not install 90° elbows directly into pump inlet.

2.Flooded suction systems should have gate valves installed on suction and discharge pipes for maintenance, however, the suction gate valve

should be no closer than five times the suction pipe diameter as described in this section.

3.Use a check valve in the discharge line when using this pump for any application where there is significant height to the plumbing after the pump.

4.Be sure to install check valves when plumbing in parallel with another pump. This helps prevent reverse rotation of the impeller and motor.

Electrical Installation

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. The pump must be installed by a licensed or certified electrician or a qualified service professional in accordance with the National Electrical Code and all applicable local codes and ordinances. Improper installation will create an electrical hazard which could result in death or serious injury to users, installers, or others due to electrical shock, and may

also cause damage to property.

Always disconnect power to the pump at the circuit breaker before servicing the pump. Failure to do so could result in death or serious injury to service people, pool users or others due to electric shock and/or property damage.

Read all servicing instructions before working on the pump.

The pump accepts 115-230 V, 50 or 60 Hz single phase input power. Power Connections (Figure 3) are capable of handling up to 10 AWG solid or stranded wire.

The motor controller will automatically regulate the pump speed when running on lower voltage to keep current below 13.2 A. No wiring change is required to run the pump on 115 V nominal power, the same terminals are used as with high voltage wiring.

The drive will operate on 2-Phase Line-Line-Ground electrical systems as well as Line-Neutral-Ground systems.

Wiring

1.Ensure all electrical breakers and switches are turned off before wiring the motor.

STORED CHARGE - Wait at least 5 minutes before servicing.

2.Ensure supply voltage meets the requirements listed on the motor nameplate.

3.For wiring sizes and general requirements, follow specifications defined by the current National

Electric Code and any local codes. When in doubt use a heavier gauge (larger diameter) wire.

4.Ensure all electrical connections are clean and tight.

5.Cut all wiring to the appropriate length so they do not overlap or touch when connected to terminals.

6.ALWAYS reinstall the drive lid after electrical installation or before leaving the pump unsupervised during servicing. This will prevent rainwater, dust or other foreign matter from accumulating in the drive.

Note: Ensure wires are not pinched between the drive body and lid.

Grounding

1.Permanently ground the motor using the Grounding Terminal (Figure 3) inside the drive wiring compartment. Refer to the current National Electrical Code and any local codes for wire size and type requirements. Ensure the ground wire is connected to an electrical service ground.

2.ONLY connect the pump to a supply circuit protected by a ground-fault circuit-interrupter (GFCI) circuit breaker.

Note: The pump should be wired to its own independent circuit unless the pump is operated in tandem with a Pentair salt chlorine generator.

Bonding

1.Using the Bonding Lug located on the side of the motor (Figure 3), bond the motor to all metal parts of the pool structure, electrical equipment, metal conduit and metal piping within 5' (1.5 m) of the inside walls of the swimming pool, spa or hot tub in accordance with the current National Electrical Code and any local codes.

Note: Pentair offers a 2-Pole 20 Amp GFCI breaker

(P/N PA220GF).

2.Solid copper bonding conductor of 8 AWG or larger is required. For Canadian installations, 6 AWG or larger solid copper bonding conductor is required.
