WARNINGS ANDTHE OWNER'S MANUAL MUST BE LEFTWITHTHE 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 orknots 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.

PUMP (Non SVRS) WARNINGS AND SAFETY INSTRUCTIONS
TO MINIMIZETHE RISK OF INJURY DUETO 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
ofemergency.
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.
HAZARDOUSPRESSURE: STAND CLEAR OFPUMP AND FILTER DURINGSTART-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. Observefilter
pressure gauge and be sure it is not higher than the pre-service condition.

NOTICE: These parameters apply to Sta-Rite equipment
only. For non-Sta-Rite equipment, consult manufacturer.
INSTALLATION (See Figure 2)
Only qualified, licensed personnel should install pump
and wiring.
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 thread seal 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
thread seal 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 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.
PUMP SUCTION
REQUIREMENTS
Pump suction is hazardous and can trap and drown
or disembowel bathers. Do not use or operate
swimming pools, spas, hot tubs or water features 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, hot tubs and water
features.
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.
Suction Outlets Per Pump (Figure 3)
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). 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 be 1.5 feet per
second unless the outlet complies with the latest
ASME/ANSI 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 ASME/ANSI 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 ASME/ANSI 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 all
current 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
rodormesh.
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 swimming pool, spa, or hot tub.
Wiring
NOTICE: 3 phase models require magnetic motor
starters and external overload protection. If in doubt
about the procedure, consult a licensed electrician.
Pump must be permanently connected to circuit. Table
I, Page 6, 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 highlighted for clarity.

OPERATION
NOTICE: NEVER run pump dry. Running pump dry may
damage seals, causing leakage and flooding. Fill pump
with water before starting motor. 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
pipes.
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.
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. Replace trap cover on trap; turn
clockwise to tighten cover.
Do not use a wrench, this may damage the trap cover
handle ring which can cause property damage or
personal injury. Tighten trap cover handle ring by hand
only (no wrenches)! 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.
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.
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
Purging the system with compressed air
can cause property damage, 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.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.

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 and use low pressure air to blow
accumulated water from the piping system. Use a pry
bar or board to remove trap covers that have been
overtightened or have taken a set and cannot be
removed by hand. Lugs have been provided on the
trap lid to use a lever or pry bar for loosening (see
Figure 6).
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.
Do not use a wrench, this may damage the trap
cover handle ring which can cause property damage
or personal injury.
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 7.
