PUMP WARNINGS AND SAFETY INSTRUCTIONS
SUCTION ENTRAPMENT HAZARD: STAY OFF THE MAIN DRAIN AND AWAY FROM ALL SUCTION
OUTLETS!
Warnings and safety instructions for Pentair Aquatic Systems pumps and other related products are available
at: http://www.pentairpool.com/pool-owner/safety-warnings/ Call [phone] for additional free copies
of these instructions. Please refer to www.pentairpool.com for more information related to Pentair Aquatic
Systems pumps.
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.
F
THIS PUMP PRODUCES HIGH LEVELS OF SUCTION AND CREATES A STRONG VACUUM AT THE
MAIN DRAIN AT THE BOTTOM OF YOUR POOL AND SPA. THIS SUCTION IS SO STRONG THAT IT CAN
TRAP ADULTS OR CHILDREN UNDER WATER IF THEY COME IN CLOSE PROXIMITY TO A POOL OR
SPA 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 ENTRAP-
MENT, 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 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 FOR SWIMMING POOLS, SPAS AND HOT TUBS, INCLUDING NSPI STANDARDS AND CPSC GUIDELINES.
READ AND KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE
For Pool and Spa Pumps (Non SVRS Pumps)
i

PUMP (Non SVRS) WARNINGS AND SAFETY INSTRUCTIONS
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 anti-entrapment 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 certified cover is properly installed.
•Replace drain covers as necessary. Drain covers deteriorate over time due to exposure to
sunlight, pool chemicals and weather.
•Avoid getting hair, limbs or body in close proximity to any suction cover, pool drain or outlet.
•Use a safety vacuum release system ("SVRS"), suction limiting system or automatic pump
shut-off system.
•Disable suction outlets or reconfigure 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.
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
Pool and spa circulation systems operate under high pressure. When any part of the circulating system (i.e.
lock 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.
CAUTION!: 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 filter without requiring the user
to place any portion of his/her body over or near the pump strainer lid or filter lid. Such installation should allow
the user to stand clear of the filter and pump during system start-up, shut down or servicing of the system.
Before servicing pool and spa 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 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 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.

Pump mount must:
Be located away from corrosive or flammable liquids.
Have enough ventilation to maintain air temperature at
less than the maximum ambient temperature rating (Max.
Amb.) listed on the motor model plate. If this pump is
installed in an enclosure/pump house, the enclosure must
have adequate ventilation and air circulation to keep the
temperature in the enclosure at or below the motor’s rated
ambient temperature whenever the pump is running.
Be solid - Level - Rigid - Vibration free. (To reduce
vibration and pipe stress, bolt pump to mount.)
Allow pump suction inlet height to be as close to water
level as possible. Pump will not lift water more than
10'(3m).
Allow use of short, direct suction pipe (To reduce friction
losses).
Allow for gate valves in suction and discharge piping.
Have adequate floor drainage to prevent flooding.
Be protected from excess moisture.
Allow adequate access for servicing pump and piping.
Fire and burn hazard. Modern motors run
at high temperatures. To reduce the risk of
fire, do not allow leaves, debris, or foreign matter to
collect around the pump motor. To avoid burns when
handling the motor, let it cool for 20 minutes before
trying to work on it.
NOTICE: When connecting threaded pipe directly to
pump, use threaded seal tape to seal connections. Do not
use pipe dope; pipe dope causes cracking in some plastics
and may damage components in piping system.
When connecting pipe to pump with union half, use
threaded seal tape between pipe and union adapter.
Union collar to pump should be assembled dry and
hand-tight.
NOTICE: Pump suction and discharge connections
have molded in thread stops. DO NOT try to screw pipe
in beyond these stops.
Taping Instructions:
Use only new or clean PVC pipe fittings.
Wrap male pipe threads with one to two layers of
threaded seal tape. Cover entire threaded portion of
pipe.
Do not overtighten or tighten past thread stop in pump
port!
If leaks occur, remove pipe, clean off old tape, rewrap
with one to two additional layers of tape and remake the
connection.
NOTICE: Support all piping connected with pump!
Piping:
Use at least 2" (51mm) pipe.
Increase size if a long run is
needed.
To avoid strains on the pump,
support both suction and
discharge pipes
independently. Place these
supports near the pump.
To avoid a strain left by a gap
at the last connection, start all
piping at the pump and run
pipe away from the pump.
To avoid airlocking, slope
suction pipe slightly upward
toward the pump.
NOTICE: To prevent flooding
when removing pump for
service, all flooded suction systems must have gate
valves in suction and discharge pipes.
POOL PUMP SUCTION
REQUIREMENTS
Pump suction is hazardous and can trap and
drown or disembowel bathers. Do not use or operate
swimming pools, spas, or hot tubs if a suction outlet
cover is missing, broken, or loose. Follow the guidelines
below for a pump installation which minimizes risk to
users of pools, spas, and hot tubs.
Entrapment Protection
The pump suction system must provide protection
against the hazard of
suction entrapment or hair entrapment/entanglement.
Suction Outlet Covers
All suction outlet covers must be maintained. They must
be replaced if cracked, broken, or missing.
See Page 5 for outlet cover certification requirements.
All suction outlets must have correctly installed, screw-
fastened covers in place.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.

5
Suction Outlets Per Pump (Figure 3, Page 5)
Provide at least two hydraulically balanced main drains,
with covers, as suction outlets for each circulating pump
suction line. The centers of the main drains (suction
outlets) on any one suction line must be at least three feet
apart.
The system must be built so that it cannot operate with
the pump drawing water from only one main drain (that
is, there must be at least two main drains connected to
the pump whenever it is running – see Figure 3, Page
5). However, if two main drains run into a single suction
line, the single suction line may be equipped with a
valve which will shut off both main drains from the pump
(see Figure 3).
More than one pump can be connected to a single
suction line as long as the requirements above are met.
Water Velocity
The maximum water velocity through the suction fitting
or cover for any suction outlet must not exceed 1.5 feet
per second unless the outlet complies with the latest
ANSI/ASME Specification for Suction Fittings For Use in
Swimming Pools, Spas, Hot Tubs, and Whirlpool
Bathtub Applications. In any case, do not exceed the
suction fitting’s maximum designed flow rate.
If 100% of the pump’s flow comes from the main drain
system, the maximum water velocity in the pump
suction hydraulic system must be six feet per second or
less even if one main drain (suction outlet) is completely
blocked. The flow through the remaining main drain(s)
must comply with the
latest ANSI/ASME
Specification for Suction
Fittings For Use in
Swimming Pools, Spas,
Hot Tubs, and Whirlpool
Bathtub Applications.
Testing and
Certification
Suction outlet covers
must have been tested
by a nationally
recognized testing
laboratory and found to
comply with the latest
ANSI/ASME
Specifications for Suction
Fittings For Use in Swimming Pools, Spas, Hot Tubs,
and Whirlpool Bathtub Applications.
Fittings:
Fittings restrict flow; for best efficiency use fewest
possible fittings (but at least two suction outlets).
Avoid fittings which could cause an air trap.
Pool fittings must conform to International Association
of Plumbing and Mechanical Officials (IAPMO)
standards.
Use only non-entrapping suction fitting or double suction.

ELECTRICAL
Ground motor before connecting to electrical
power supply. Failure to ground motor can cause
severe or fatal electrical shock hazard.
Do not ground to a gas supply line.To avoid
dangerous or fatal electrical shock, turn OFF power
to motor before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping
indicates an electrical problem. If GFCI trips and
will not reset, have a qualified electrician inspect and
repair electrical system.
Exactly match supply voltage to nameplate
voltage. Incorrect voltage can cause fire or
seriously damage motor and voids warranty. If in
doubt consult a licensed electrician.
Voltage
Voltage at motor must be not more than 10% above or
below motor nameplate rated voltage or motor may
overheat, causing overload tripping and reduced
component life. If voltage is less than 90% or more than
110% of rated voltage when motor is running at full
load, consult power company.
Grounding/Bonding
Install, ground, bond and wire motor according to local
or the current National Electrical Code requirements.
Permanently ground motor. Use green ground terminal
provided under motor canopy or access plate (See
Figure 4); use size and type wire required by code.
Connect motor ground terminal to electrical service
ground.
Bond motor to pool structure. Use a solid copper
conductor, size No. 8 AWG (8.4 sq.mm) or larger. Run
wire from external bonding lug (see Figure 4) to
reinforcing rod or mesh.
Connect a No. 8 AWG (8.4 sq.mm) solid copper
bonding wire to the pressure wire connector provided
on the motor housing and to all metal parts of the
swimming pool, spa, or hot tub and to all electrical
equipment, metal piping or conduit within 5 feet
(1.5 m) of the inside walls of the swimming pool, spa,

Pump must be permanently connected to circuit. Table
I, Page 7, give correct wire and circuit breaker sizes for
the pump alone. If other lights or appliances are also on
the same circuit, be sure to add their amp loads to
pump amp load before figuring wire and circuit breaker
sizes. (If unsure how to do this or if this is confusing,
consult a licensed electrician.) Use the load circuit
breaker as the master on-off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in
circuit; it will sense a short-circuit to ground and
disconnect power before it becomes dangerous to pool
users. For size of GFCI required and test procedures for
GFCI, see manufacturer’s instruction.
In case of power outage, check GFCI for tripping (which
will prevent normal pump operation). Reset if
necessary.
NOTICE: If you do not use conduit when wiring motor,
be sure to seal wire opening on end of motor to prevent
dirt, bugs, etc., from entering.
Risk of
dangerous or
fatal electrical shock. Be
sure that power to the motor
circuit is off before working
on wiring, wiring
connections, or motor. Re-
install the motor end cover
and all other wiring covers
before turning on the power.
1. Turn off power.
2. Remove the motor end
cover.
To Wire a Single Speed,
Single Voltage Motor
There are two terminals
labeled L1 and L2. Attach the
power leads to these terminals.
Either wire may attach to either terminal.
To Wire a Dual-Voltage Motor
Dual voltage motors have a plug to change from 230
volts (factory setting) to 115 volts.
1. If you have 230 volts motor supply voltage, confirm
that the plug is set for 230 volts. The arrow on the
plug will point to the 230 volt position. Note that plug
only connects with one prong in this position.
2. If you have 115 volt supply, pull the plug straight up
and place it on the two brass prongs as shown.
NOTE: Arrow is highlightedfor clarity.
To Wire a Two-Speed Motor
Wire the pump as shown in the diagram on page 6.
OPERATION
DO NOT run the pump dry. If the pump is run dry,
the mechanical seal will be damaged and the pump
will start leaking. If this occurs, the damaged seal
must be replaced. ALWAYS maintain proper water
level. If the water level falls below the suction port,
the pump will draw air through the suction port,
losing the prime and causing the pump to run dry,
resulting in a damaged seal. Continued operation in
this manner could cause a loss of pressure,
resulting in damage to the pump case, impeller and
seal and may cause property damage and personal
injury.
Before removing trap cover:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge air.
3. RELEASE ALL PRESSURE from pump and piping
system.
If pump is being pressure tested, be sure pressure
has been released before removing trap cover.
Do not block pump suction. To do so with body
may cause severe or fatal injury. Small children
using pool must ALWAYS have close adult supervision.
Fire and burn hazard. Modern motors run
at high temperatures. To reduce the risk of fire, do not
allow leaves, debris, or foreign matter to collect around
the pump motor. To avoid burns when handling the
motor, let it cool for 20 minutes before trying to work on
it. An automatic internal cutoff switch protects the motor
from heat damage during operation.
NOTICE: Maximum ambient temperature for motor
operation must not exceed maximum ambient
temperature on motor nameplate.
Priming Pump
Release all pressure from filter, pump, and piping
system; see the filter owner’s manual.
In a flooded suction system (water source higher than
pump), pump will prime itself when suction and
discharge valves are opened.
If pump is not in a flooded suction system, unscrew and
remove trap cover; fill trap and pump with water.
Clean and inspect O-Ring; reinstall on trap groove.
Do not lubricate the trap cover O-Ring. The original
equipment O-Ring contains a permanent internal
lubricant.
NOTICE: If you replace the
O-Ring with a non-internally lubricated O-Ring, you may
need to apply a silicone based lubricant.
Hazardous voltage.
Can shock, burn,
or cause death.
Disconnect power
before working
on pump or motor.

Replace trap cover on trap; turn clockwise to
tighten cover.Tighten trap cover
handle ring by hand only Do not use a
wrench, this may damage the trap
cover handle ring which can cause property damage or
personal injury. See Figure 1,
Page 3.
Pump should prime now. Priming time will depend on
vertical length of suction lift and horizontal length of
suction piping.
If pump does not prime, make sure that all valves are
open, suction pipe end is under water, pump is not trying
to lift water more than 10'(3m), and that there are no leaks
in suction pipe. See Troubleshooting Guide, Page 11.
Routine Maintenance
The only routine
maintenance needed is
inspection/cleaning of
trap basket. Debris or
trash that collects in
basket will choke off
water flow through the
pump. Follow instructions
below to clean trap:
1. Stop pump, close
valves in suction and
discharge, and release
all pressure from
system before
proceeding.
2. Remove trap cover
handle ring (turn
counterclockwise). If
necessary, tap handles
gently with a rubber mallet.
3. Remove strainer basket and clean. Be sure all holes
in basket are clear, flush basket with water and
replace in trap with large opening at pipe connection
port (between ribs provided). If basket is replaced
backwards cover will not fit on trap body.
4. Clean and inspect lid O-Ring; reinstall on trap
groove.
5. Clean O-Ring groove on trap body and replace cover
and handle ring. To help keep cover from sticking,
tighten hand tight only.
6. Prime pump (see priming instructions).
Storage/Winterizing
NOTICE: Allowing pump to freeze will damage pump
and void warranty!
NOTICE: Do not use anti-
freeze solutions (except
propylene glycol) in your
pool/spa system. Propylene
glycol, “RV antifreeze”, is non-
toxic and will not damage
plastic system components;
other anti-freezes are highly
toxic and may damage plastic
components in the system.
Drain all water from pump and
piping when expecting
freezing temperatures or when
storing pump for a long time
(see instructions below).
Keep motor dry and covered
during storage.
To avoid
condensation/corrosion
problems, do not cover pump
with plastic.
Hazardous voltage.
Can shock, burn,
or cause death.
Disconnect power
before working
on pump or motor.

Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.

10
For outdoor/unprotected
installations:
1. Enclose entire system in a
weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow
ventilation; do not wrap system in plastic.
3. Use a 40% propylene glycol/60% water solution to
protect pump to -50°F (-46°C).
Draining Pump
Separation hazard. Purging the system
with compressed air can cause
components to violently separate, with risk of severe
injury or death to anyone nearby. Use only a low
pressure (below 5 PSI), high volume blower when air
purging the pump, filter, or piping.
1. Pump down water level below all inlets to the pool.
To avoid dangerous or fatal electrical shock
hazard, turn OFF power to motor before draining
pump.
2. Remove trap cover handle ring (turn
counterclockwise). If necessary, tap handles gently
with a rubber mallet. Low pressure air can be used to
remove remaining water from the piping.
3. Cap inlet piping after draining to keep water out
of the pipes.
4. To prevent pump from freezing, remove trap cover and
drain the tank body through the two drain plugs
provided.
A. Gravity drain system as far as possible.
B. Protect areas which retain water with non-toxic
propylene glycol antifreeze (“RV” antifreeze).
5. Clean pump thoroughly; replace trap cover.
Tighten trap cover handle ring by hand
only Do not use a wrench, this may damage the trap
cover handle ring which can cause property damage or
personal injury.
If pump is not anchored, use caution to not break
attached piping!
6. Be sure motor is kept dry and covered.
Startup For Winterized Equipment
1. Remove any temporary weather protection placed
around system for shutdown.
2. Follow filter manufacturer’s instructions for
reactivation of the filter.
3. Inspect all electrical wiring for damage or
deterioration over the shutdown period. Have a
qualified serviceman repair wiring as needed.
4. Inspect and tighten all watertight connections.
5. Open all valves in suction and return piping.
6. Remove any winterizing plugs in piping system.
7. Drain all antifreeze from system.
8. Close all drain valves and replace all drain plugs in
piping system.
9. Prime pump according to instructions on Page 8.

Suction leaks/lost prime:
1.
Pump must be primed; make sure that pump volute
and trap are full of water. See priming instructions,
Page 8.
2. Make sure there are no leaks in suction piping.
3. Make sure suction pipe inlet is well below the water
level to prevent pump from sucking air.
4. If suction trap O-Ring is defective, replace it.
5. Make sure pump is not trying to lift water more than
10' (3m).
6. Make sure suction pipe is at least 2" (51mm) in diameter.
Clogged pipe/trap/impeller, worn impeller:
7. Make sure suction trap is not clogged; if it is, clean
trap and strainer.
8. Make sure impeller is not clogged (follow steps 1
through 7 under “Removing Old Seal”, Page 11;
check impeller for clogging; follow steps 7 through
