low instructions can cause severe injury and/or death.
WARNING – This product should be installed and serviced only by a qualified professional.
CAUTION – All electrical wiring MUST be in conformance with all applicable local codes, regulations, and
the National Electric Code (NEC).
USE OF NON-HAYWARD REPLACEMENT PARTS VOIDS WARRANTY.
ATTENTION INSTALLER - THIS MANUAL CONTAINS IMPORTANT INFORMATION ABOUT THE INSTALLATION,
OPERATION, AND SAFE USE OF THIS VARIABLE SPEED PUMP THAT MUST BE FURNISHED TO THE END USER OF THIS
PRODUCT. FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS COULD RESULT IN SERIOUS INJURY.
WARNING – To reduce risk of injury, do not permit children to use or climb on this product. Closely
supervise children at all tim
es. Components such as the filtration system, pumps, and heaters must be positioned
to prevent children from using them as a means of access to the pool.
CAUTION – This pump is intended for use on permanently installed swimming pools and may also be used
with hot tub
s 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.
Though this product is designed for outdoor use, it is strongly advised to protect the electrical components from the
weather. Select a well-drained area, one that will not flood when it rains. It requires free circulation of air for
cooling. Do not install in a damp or non-ventilated location. If installed within an outer enclosure or beneath the
skirt of a hot tub or spa, adequate ventilation and free circulation of air must be provided to prevent overheating of
the motor.
WARNING – Pool and spa components (seals, gaskets, etc.) have a finite life. All components should be
inspected frequently and replaced at lea
st every ten years, or if found to be damaged, broken, cracked, missing, or
not securely attached.

WARNING – Risk of Electric Shock. All electrical wiring MUST be in conformance with applicable local
codes, regulations, and the National Electric Code (NEC). Hazardous
voltage can shock, burn, and cause death or
serious property damage. To reduce the risk of electric shock, do NOT use an extension cord to connect unit to
electric supply. Provide a properly located electrical receptacle. Before working on pump or motor, turn off power
supply to the pump.
WARNING – To reduce the risk of electric shock replace damaged wiring immediately. Locate conduit to
prevent abuse from lawn mowers, hedge trimmers and other equipment.
WARNING – Electrical ground all electrical equipment before connecting to electrical power supply. Failure to ground
all electrical equipment can cause serious or fatal electrical shock hazard.
WARNING – Do NOT ground to a gas supply line.
WARNING – To avoid dangerous or fatal electrical shock, TURN OFF POWER to all electrical equipment before working.
WARNING – Risk of Electric Shock. In accordance with the National Electric Code (NEC), 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. The 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 circuit 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.
WARNING – Failure to bond pump to pool structure will increase risk for electrocution and could result in
injury or death. To reduce t
he risk of electric shock, see installation instructions and consult a professional
electrician on how to bond pump. Also, contact a licensed electrician for information on local electrical codes for
bonding requirements.
Notes to electrician: Use a solid copper conductor, size 8 or larger. Run a continuous wire from external bonding lug
to reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm
2
) [No. 6 AWG (13.3 mm
2
) for Canada] solid copper bonding
wire to the pressure wire connector provided on the pump housing and to all metal parts of swimming pool, spa, or
hot tub, and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside
walls of swimming pool, spa, or hot tub. IMPORTANT - Reference NEC codes for all wiring standards including, but
not limited to, grounding, bonding and other general wiring procedures.
WARNING – Suction Entrapment Hazard. Suction in suction outlets and/or suction outlet covers, which are
damaged, broken, cracked,
missing, or unsecured cause severe injury and/or death due to the following entrapment
hazards (symbols complements of APSP):
Hair Entrapment - Hair can become entangled in suction outlet cover.
Limb Entrapment - A limb inserted into an opening of a suction outlet sump or suction outlet cover that is damaged,
broken, cracked, missing, or not securely attached can result in a mechanical bind or swelling of the limb.
Body Suction Entrapment - A differential pressure applied to a large portion of the body or limbs can result in an
entrapment.
Evisceration/ Disembowelment - A negative pressure applied directly to the intestines through an unprotected
suction outlet sump or suction outlet cover which is damaged, broken, cracked, missing, or unsecured can result in
evisceration/disembowelment.
Mechanical Entrapment - There is potential for jewelry, swimsuits, hair decorations, fingers, toes, or knuckles to be
caught in an opening of a suction outlet cover resulting in mechanical entrapment.
USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 5 of 20 PowerFlo VS Variable Speed Pump IS1580X15VSP Rev-B
WARNING – To Reduce the risk of Entrapment Hazards:
When outlets
are small enough to be blocked by a person, a minimum of two functioning suction outlets per
pump must be installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum of
three feet (3’) [0.91 meter] apart, as measured from near point to near point.
Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
The maximum system flow rate shall not exceed the flow rating as listed on the suction outlet cover.
Never use pool or spa if any suction outlet is damaged, broken, cracked, missing, or not securely attached.
Replace damaged, broken, cracked, missing, or not securely attached suction outlet components
immediately.
In addition to two or more suction outlets per pump installed in accordance with latest APSP standards and
CPSC guidelines, follow all national, state, and local codes applicable.
Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
WARNING – Hazardous Pressure. Pool and spa water circulation systems operate under hazardous
pressure during start-up, n
ormal operation, and after pump shut-off. Stand clear of circulation system equipment
during pump start-up. Failure to follow safety and operation instructions could result in violent separation of the
pump housing and cover due to pressure in the system, which could cause property damage, severe personal injury,
or death. Before servicing pool and spa water circulation system, all system and pump controls must be in off
position and filter manual air relief valve must be in open position. Before starting pump, all system valves must be
set in a position to allow system water to return back to the pool. Do not change filter control valve position while
pump is running. Before starting pump, fully open filter manual air relief valve. Do not close filter manual air relief
valve until a steady stream of water (not air or air and water mix) is discharged from the valve. All suction and
discharge valves MUST be OPEN when starting the circulation system. Failure to do so could result in severe
personal injury and/or property damage.
WARNING – Separation Hazard. Failure to follow safety and operation instructions could result in violent
separation of
pump components. Strainer cover must be properly secured to pump housing with strainer cover lock
ring. Before servicing pool and spa circulation system, all system and pump controls must be in off position and
filter manual air relief valve must be in open position. Do not operate pool and spa circulation system if a system
component is not assembled properly, damaged, or missing. Do not operate pool and spa circulation system unless
filter manual air relief valve body is in locked position in filter upper body. All suction and discharge valves MUST be
OPEN when starting the circulation system. Failure to do so could result in personal injury and/or property damage.
WARNING – Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from
the suction outlets can res
ult in an increase potential for suction entrapment as described above.
WARNING – Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and
other material can result in
an increase potential for suction entrapment as described above.
WARNING – Never operate the circulation system at more than 30 PSI maximum.
WARNING – Never change the filter control valve position while the pump is running.
WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly isolated
fro
m any flammable structures or foreign debris they can cause fires, which may cause severe personal injury or
death. It is also necessary to allow the motor to cool for at least 20 minutes prior to maintenance to minimize the
risk for burns.
WARNING – Failure to install according to defined instructions may result in severe personal injury or
death.

3. Installation and Wiring
WARNING – This product should be installed and serviced only by a qualified professional.
No
te: For FCC part 15 compliance, use flexible metallic conduit or a shielded power supply cable when installing this
device.
3.1. Pump Location
The PowerFlo VS 300 pump MUST be installed below the pool
water line (see Figure to right).
Install pump on a firm, level base or pad to meet all local and
national codes. The field supplied base or pad must be level and
vibration-free.
Pump motors require free circulation of air for cooling.
Do NOT install pump in a damp or non-ventilated location.
Though the pump is designed for outdoor use, it is strongly
advised to protect the electrical components from the weather.
Select a well-drained area, one that will not flood when it rains.
3.2. Pump Mounting
Install pump on a level concrete slab or other rigid base to meet all local and national codes. Secure pump to base
with screws or bolts to further reduce vibration and stress on pipe or hose joints. The base must be level, rigid, and
vibration free. Pump mount must:
Allow pump inlet height to be below wate
r level.
Allow use of s
hort, direct suction
pipe (to reduce friction losses).
Allow for valves in suction and discharge piping.
Be protected f
rom excess moisture and flooding.
Allow adequate access for servicing pump
and piping.
3.3. Plumbing
1. Use PTFE tape to seal threaded connections on molded plastic components. All plastic fittings must be new or
thorou
ghly cleaned before use. NOTE - Do NOT use Plumbe
r’s Pipe Dope as it may cause cracking of the plastic
components.
When applying PTFE tape to plastic threads, wrap the entire
threaded portion of the male fitting
with one to two layers of tape. Wind the t
ape clockwise as you face the open end of the fitting, be
ginning at the
end of the fitting. The pump suction and outlet ports have molded-in
thread stops.
Do NOT attempt to force
hose connector fitting past
this stop. It is only necessary to tighten fittings enough to
prevent leakage. Tighten
fitting by hand and then use a tool to engage fitting an additional 1
½ turns. Use
care when using PTFE tape as
friction is reduced considerably; do NOT
over-tighten fitting or you may ca
use damage. If leaks occur, remove
connector, clean off
old PTFE tape, re-wrap with one to two additional layers of PTFE tape, and re
-install
connector.
2. Piping -
Flexible Hose, PVC, or Reinforced Hose are all acceptable piping meth
ods.
3. For pu
mp outlet use 1-1/2" PVC pipe or reinforced hose. For pump su
ction on ALL models, use 1-1/2" reinforced
hose. Increase size if a long run is needed. For pipe larger than port, use reducing fitting in strainer port.
4. To avoid pump strain, supp
ort suction and outlet independently. Place supports near pump. To avoid strain le
ft
by a gap at last connection, start
all piping at pump and run pipe AWAY from pump.
5. NEVER use suction pipe SMALLER than pump suction connections.
Suction pipe inlet must be lower than pump
inlet port.
6. Fittings (elb
ows, tees, valves, etc.) restrict flow. For better efficiency, use the fewest possibl
e fittings. Avoid
fittings that c
ould cause an air trap. Pool and spa fittings MUST conform to the
International Association of Plumbing and Mechanical Officials (IAPMO) standards.

2. Permanently ground pump. Use green ground terminal
provided under access plate; use size and type wire
required by c
ode. Connect ground termin
al to electrical service ground.
3. Bond pu
mp to pool structure. Bonding will connect all metal parts wi
thin and around the pool with a continuous
wire. Bonding reduces the risk of a current passing b
etween bonded metal object
s, which could potentially
cause electrical shock if grounded or shor
ted. Refere
nce NEC codes for all wiring standards including, but not
limited to, grounding, bo
nding and genera
l wiring procedures.

5. Storage / Winterization
WARNING – Separation Hazard. Do not purge the system with compressed air. Purging the system with
compressed a
ir can cause components to explode, 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.
ATTENTION – Allowing the pump to freeze with water in it will void the warranty.
ATTENTION – Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol 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). Gravity drain system as far as possible.
Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap pump
with plastic film or bags.
5.1. Storing Pump For Winterization

8. Troubleshooting
8.1. General Problems
Motor Will NOT Start:
1. Check for and correct any improper or loose wiring connections; open switches or relays; trippe
d circuit
breakers, or blown f
u
ses.
2. Manually check the rotation of the m
otor shaft for free movement and lack of obstruction. Corre
ct if
necessary.
Mo
tor Shuts OFF:
1. Check for low voltage or power drop at the motor (frequently caused by undersized
wiring). Contact a
qualified professional to verify the electrical connections.
Mot
or Hums, But Does NOT Start:
1. Impeller jammed with debris. Have a qualified repair professional open the pump and remove
the debris.
Low
Flow – Generally:
1. Clogged or restricted strainer or suction line. Contact
a qualified repair professional.
2. Undersized pool piping. Correct the piping size.
3. Plugged or re
stricted discharge line of filter, valve partially closed (high gauge read
ing). Sand filters –
backwash as per manu
facturer’s instructions; D.E. filters – backwash as per manu
facturer’s instructions;
Cartridge filters – clean or r
e
place the cartridge.
4. Air leak in suc
tion (bubbles issuing from return fitti
ngs). Re-tighten the suction and discharge connections
using P
TFE tape. Inspect other plumbing connections,
and tighten as required.
5. Plugged, restricted, or dam
aged impeller. Replace the impeller including a new seal assembly.
Noisy Pump:
1. Air leak in suction piping causing rumbling in pump.
2. Cavitation due to restricted
or undersized suction line or leak at any joint, lo
w water level in pool, and
unrestricted discharge return lines. Corre
ct suction condition or throttle return lines, if practical.
Holding
hand over ret
urn fitting will sometimes prove this
point or putting in a smaller eyeball fitting.
3. Vibration due to improper
mounting, etc. Put a rubbe
r pad under metal mounting feet.
4. Foreig
n matter in pump housing. Loose stones/debris hitting impeller could be cause, remove an
y of the
above.
5. Motor
bearings noisy from normal wear, rust, overheating, or concentr
ation of chemicals causing seal
damage whic
h will allow chlorinated water to seep into bearings wiping out the grease causing be
aring to
whine. All seal leaks should be replaced at once.
6. Equipment base vibrating.
