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.

SUCTION ENTRAPMENT HAZARD: STAY OFF
THE MAIN DRAIN AND AWAY FROM ALL SUCTION
OUTLETS!
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.
NOTE: ALL SUCTION PLUMBING MUST BE INSTALLED IN ACCORDANCE
WITH THE LATEST NATIONAL AND LOCAL CODES, STANDARDS AND
GUIDELINES.
THIS PUMP IS NOT EQUIPPED WITH SAFETY VACUUM
IMPORTANT SAFETY INSTRUCTIONS
ii
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.
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
• All work must be performed by a qualied service 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 specic model.
All models are intended for use in swimming pool applications.
The pump will function correctly only if it is properly sized to the
specic 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, fire, flooding, suction entrapment
or severe injury or property damage caused by a structural failure of the
pump or other system component.
Pumps and replacement motors that are single speed and one (1)
Total HP or greater cannot be sold, offered for sale, or installed in a
residential pool for filtration use in California, Title 20 CCR sections
1601-1609.
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.

INSTALLATION
Only a qualied plumbing professional should install the pump. Refer to IMPORTANT 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.
ENSURE THE INSTALL LOCATION MEETS THE
FOLLOWING REQUIREMENTS:
1. Install the pump as close to the pool or spa as
possible. To reduce friction loss and improve
eciency, use short, direct suction and return piping.
2. Install a minimum of 5 ft. (1.5 m) from the inside wall
of the pool and spa. Canadian installations require
a minimum of 9.8 ft. (3 m) from the inside wall of the
pool.
3. Install the pump a minimum of 3 ft. (0.9 m) from the
heater outlet.
4. Do not install the pump more than 10 ft. (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.).
6. Install the pump with a rear clearance of at least
3 inches (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 ve (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 port. This will help
the pump prime faster and last longer.
Note: DO NOT install 90° elbows directly into the
suction or discharge ports.

Fittings and Valves
1. Do not install 90° elbows directly into suction port.
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 ve 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
signicant 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 certied electrician or a qualied
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 13.6 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 o 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
specications dened 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: Pentair oers a 2-Pole 20 Amp GFCI breaker
(P/N PA220GF).
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 ft. (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.
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.
