WARNING – Pool and spa components (seals, gaskets, etc.) have a nite life. All components should be
inspected frequently and replaced at least 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 – 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 qualied 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 in-
terrupts power to the pump without the test button being pushed, a ground current is owing, indicating the possibil-
ity of an electric shock. Do not use this pump. Disconnect the pump and have the problem corrected by a qualied
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 the risk of electric shock, see installation instructions and consult a professional electri-
cian 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 mm2) [No. 6 AWG (13.3 mm2) 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 includ-
ing, 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 entrap-
ment 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, ngers, toes, or knuckles to be
caught in an opening of a suction outlet cover resulting in mechanical entrapment.

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. oor 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 ttings shall be placed in such locations and distances to avoid “dual blockage” by a user.
• Dual suction ttings shall not be located on seating areas or on the backrest for such seating areas.
• The maximum system ow rate shall not exceed the values shown in the “Pipe Sizing Chart” found in section 4.3
below.
• Never use pool or spa if any suction outlet component 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, normal 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 posi-
tion and lter 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 lter control valve position while pump is
running. Before starting pump, fully open lter manual air relief valve. Do not close lter 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
lter 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
lter manual air relief valve body is in locked position in lter upper body. 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 – Never operate the circulation system at more than 50 PSI maximum.
WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly iso-
lated from any ammable structures or foreign debris they can cause res, 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 dened instructions may result in severe personal injury or
death.

Energy Efficiency Overview and Power consumption
The energy consumed by a pool pump is measured in terms of Watts (W) or Kilowatts (kW). Because the VS Omni displays power consumption in watts, you
can easily determine the cost of operating the pump at the given speed. After installation, to display power consumption at any time, follow the screens below:
The power consumption will be displayed in watts. To calculate power costs, refer to the example below:
VS Omni Variable Speed Pump operating at 300 W. Cost of electricity = *$0.10 per kWh
Convert Watts to Kilowatts: 300 W = 0.3 kW
0.3 kW X $0.10/kWh = $0.03 per hour
*National Average (use your actual cost of electricity for more accurate results)
Note the power consumption is greatly affected by the speed of the pump. Lowering the speed of the pump can drastically reduce the power that is consumed.
Below are some of the major benefits of running the pump at lower speeds.
• Save electricity and money
• Improved filtration – the filter can often remove smaller particles when the water moves slower
• Quiet operation
• Reduced Total Dynamic Head – less stress on equipment (e.g. filter) which can lengthen equipment life
When determining the speed(s) to operate your pump, you must also take into account the minimum requirements for proper sanitation and equipment/water
feature functionality.
It is recommended you filter (“turnover”) all the water in the pool at least once every 24 hours. Check with local requirements for the minimum turnover rate.
Running the pump at a lower speed may require running the pump for a longer period of time in order to meet the turnover requirements for proper sanitation.
Equipment such as heaters, skimmers, and chlorinators require minimum flows to operate correctly. Refer to individual equipment manuals for specific flow
requirements.
After setting the pump speed(s), it is recommended you check that all other equipment/water features are functioning as intended. For example, when running
at a low speed for daily filtration, verify water is adequately flowing over the skimmer weirs. Operate the pump at higher speeds for the shorter periods of time
needed to operate a heater, water feature, etc.

Installation
Pump Location
Locate pump as close to the pool as possible, in compliance with local codes. To reduce friction loss, suction lines should as direct as they can be. Suction lines
should have continuous slope upward from lowest point in line. Joints must be tight (but not over-tightened). Suction line diameter must equal or be larger
than the discharge line diameter.
Though the pump is designed for outdoor use, it is advised to place pump and filter in the shade to shield them from
continuous direct heat. Select a well-drained area that will not flood when it rains. Do NOT install pump and filter in a
damp or non-ventilated location. Keep motor clean. Pump motors require free circulation of air for cooling.
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 vibra-
tion 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 as close to water level as possible.
• Allow use of short, direct suction pipe (to reduce friction losses).
• Allow for valves in suction and discharge piping.
• Be protected from excess moisture and flooding.
• Allow adequate access for servicing pump and piping.
Pipe Sizing Chart
Note: It is recommended that a minimum length of straight piping (shown as “L” in above diagram), equivalent to 5 pipe size diameters, be used between the
pump suction inlet and any plumbing fittings (elbows, valves, etc.).
When installing the VS Omni pump, care should be taken to ensure proper pipe and equipment sizing to handle the maximum flow required. It is recommended
to set the maximum speed in order to not exceed the maximum flow rate. After installation is complete, set maximum speed during configuration of the VSP. For
more information, refer to the Configuration section in the VS Omni Installation manual.
WARNING – Hazardous Pressure. Pumps, filters, and other equipment/ components of a swimming pool filtration system operate under pressure. Incorrectly
installed and/or improperly tested filtration equipment and/or components may fail resulting in severe personal injury or death.
Plumbing
1. Use PTFE tape to seal threaded connections on molded plastic components. All plastic fittings must be new or thoroughly cleaned before use. Do NOT
use Plumber’s Pipe Dope as it may cause cracking of the plastic components. When applying PTFE tape to plastic threads, wrap the entire threaded por-
tion of the male fitting with one to two layers of tape. Wind the tape clockwise as you face the open end of the fitting, beginning 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 cause 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. Fittings (elbows, tees, valves, etc.) restrict flow. For better efficiency, use the fewest possible fittings. Avoid fittings that could cause an air trap. Pool
and spa fittings MUST conform to the International Association of Plumbing and Mechanical Officials (IAPMO) standards.

Electrical
Use copper conductors only. For indoor & outdoor use. Connect pump to a 15 amp branch circuit in accordance with local codes, regulations, and the National
Electric Code (NEC). A disconnecting means located at least 5 ft. from the inside wall of the pool, spa, or hot tub must be provided.
Voltage
Voltage at pump MUST NOT be more than 10% above or below nameplate rated voltage, or components may overheat, causing overload tripping and reduced
component life. If voltage is less than 90% (207 VAC) or more than 110% (253 VAC) of rated voltage (230 VAC) when pump is running at full load, consult the
power company.
Grounding and Bonding
1. Install, ground, bond, and wire pump in accordance with local or national electrical code requirements.
2. Permanently ground pump. Use green ground terminal provided under access plate; use size and type wire required by code. Connect ground terminal to
electrical service ground.
3. Bond pump to pool structure. Bonding will connect all metal parts within and around the pool with a continuous wire. Bonding reduces the risk of a current
passing between bonded metal objects, which could potentially cause electrical shock if grounded or shorted. Reference NEC codes for all wiring standards
including, but not limited to, grounding, bonding and general wiring procedures.
4. Use a solid copper conductor, size 8 or larger. Run wire from external bonding lug to reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm2) [No. 6 AWG
(13.3 mm2) for Canada] solid copper bonding wire to the pressure wire connector provided on the motor 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.
Wiring
1. Pump MUST be permanently connected to circuit. If other lights or appliances are also on the same circuit, be sure to add their amp loads before calculating
wire and circuit breaker sizes. Use the circuit breaker as the master On-Off switch.
2. The pump requires constant input power whether from the VS Omni Hub using the Wiring Whip or directly from a service panel/switch/timeclock.
Wiring Whip
A High Voltage Wiring Whip (6ft flexible conduit containing three 12AWG conductors - red, black and green) has been provided to connect the VS Omni Hub to
the VSP, ONLY IF THE VS OMNI HUB WILL BE POWERED BY 230 VAC. Refer to the Quick Start Guide for more detail. If powering the Hub by 115 VAC, the pump
will have to be wired separately.
Communication Cable
A 15 ft, 3 conductor (red, black and bare wire) low voltage communication cable has been provided for the connection from the VS Omni Hub to the VSP. The
bare wire is only used with TriStar VS 900 Omni, Super Pump VS 700 Omni and MaxFlo VS 500 Omni models only. Tape off or snip the bare wire when used
with TriStar VS 950 Omni.
TriStar VS 950 Omni Wiring Connections
Both the high voltage input power and the low voltage communication cable need to be connected to the TriStar VS 950 Omni pump. Both connections are ac-
cessible in the drive wiring compartment found underneath the cover plate. Refer to the following steps when wiring the TriStar VS 950 Omni.

2. Low Voltage Wiring - Wiring connections for the TriStar VS 950 Omni are shown below. When wiring the low voltage communication cable, refer the to
table below. One conductor will go from screw terminal “2” on the VS Omni Hub to screw terminal “7” on the TriStar VS 950 Omni pump. The other conductor
will go from screw terminal “3” on the VS Omni Hub to screw terminal “8” on the pump. The bare wire will not be used and can be snipped off at the ends. Route
the cable as shown, making sure that it does not run across any high voltage wiring. The communication cable must exit in its own conduit opening as shown,
using appropriate waterproof fittings and conduit.
3. High Voltage Wiring - If the VS Omni Hub is being powered by 230 VAC, the easiest method for bringing power to the pump is using the provided Wiring
Whip as shown in Step 2 on the Quick Start Guide. If the VS Omni Hub is being powered by 115 VAC or if the pump and Hub are not in the same vicinity, it is
recommended that power be brought to the pump from a nearby service panel. If power is coming from a timeclock, it must be set to run continuously to assure
that power is always available to the pump.
Refer to the diagram above for the location of the 230 VAC connections and ground. Run wiring through its own conduit opening as shown, If not using the Wiring
Whip, use appropriate waterproof fittings and conduit. Re-install the cover plate and secure.

the VS Omni Hub to screw terminal “B” on the pump. The bare wire will attach to screw terminal “4” on the VS Omni Hub and “COM” on the pump.
4. High Voltage Wiring - If the VS Omni Hub is being powered by 230 VAC, the easiest method for bringing power to the pump is using the provided Wiring
Whip as shown in Step 2 on the Quick Start Guide. If the VS Omni Hub is being powered by 115 VAC or if the pump and Hub are not in the same vicinity, it is
recommended that power should be brought to the pump from a nearby service panel. If power is coming from a timeclock, it must be set to run continuously
to assure that power is always available to the pump.
Refer to the diagram above for the location of the 230 VAC connections and ground. Run wiring through its own conduit opening as shown, If not using the Wiring
Whip, use appropriate waterproof fittings and conduit.
Once completed, the cover plate and display will need to be re-installed but DO NOT re-attach the display cable. The display is now disabled and the VS Omni
system will fully control all pump functions.
Operation
Prior to Start-Up
If it is necessary to perform a water pressure test prior to initial use to ensure plumbing system is functioning properly, then the following criteria should be
maintained for this test:
1. Have a professional perform this test.
2. Ensure all Hayward pump and system components are removed from system prior to performing test.
WARNING – If circulation equipment must remain in the plumbing system during water pressure test, do not apply more than 10 psi pressure to the system.
Be sure water pressure has been released, using the filter manual air relief valve, before removing pump strainer cover.
WARNING – All suction and discharge valves MUST be OPEN, as well as filter air relief valve (if available) on filter, when starting the circulating pump system.
Failure to do so could result in severe personal injury.

Starting/Priming the Pump
Note that starting and priming will require that the VS Omni pump has been configured. Refer to the VS Omni Installation manual for instructions on the con-
figuration and operation of the pump. After configuration, start and prime the pump using the Control Pad.
Fill strainer housing with water to suction pipe level. If water leakage occurs from anywhere on the pump or filter, DO NOT start the pump. If no leakage occurs,
stand at least 10 feet from pump and/or filter and proceed with starting the pump.
WARNING – Return to filter to close filter manual air relief valve when a steady stream of water (not air or air and water) is discharged from valve. Failure to
do so could result in severe personal injury.
ATTENTION – NEVER OPERATE THE PUMP WITHOUT WATER. Water acts as a coolant and lubricant for the mechanical shaft seal. NEVER run pump dry. Run-
ning pump dry may damage seals, causing leakage, flooding, and voids warranty. Fill strainer housing with water before starting motor.
ATTENTION – Do NOT add chemicals to pool/spa system directly in front of pump suction. Adding undiluted chemicals may damage pump and voids warranty.
ATTENTION – Before removing strainer cover:
1. STOP PUMP before proceeding.
2. CLOSE VALVES in suction and outlet pipes.
3. RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See filter owner’s manual for more details.
4. If water source is higher than the pump, pump will prime itself when suction and outlet valves are opened. If water source is lower than the pump, remove
strainer cover; fill strainer housing with water.
5. Clean and lubricate strainer cover O-ring with “Jack’s 327” if necessary.
6. Replace strainer cover on strainer housing.
Turn on power and wait for pump to prime, which can take up to fifteen (15) minutes. Priming time will depend on vertical length of suction lift and horizontal
length of suction pipe. If pump does NOT prime within 15 minutes, stop motor and determine cause. Be sure all suction and discharge valves are open when
pump is running.
Troubleshooting
Motor Will NOT Start
• Check that supply voltage is wired properly and available at the pump.
• Check that low voltage communication cable is wired properly for your model according to the tables shown on page 9 and 10.
• Check the rotation of the motor shaft for free movement and lack of obstruction. Correct if necessary.
Motor Shuts OFF
• Check for low voltage or power drop at the motor (frequently caused by undersized wiring). Contact a qualified professional to verify the electrical con-
nections.
Motor Hums, But Does NOT Start
• Check if impeller is jammed with debris. Have a qualified repair professional open the pump and remove the debris.
Pump Won’t Prime
• Empty pump/strainer housing. Make sure the pump/strainer housing is filled with water and the cover o-ring is clean. Ensure the o-ring is properly seated
in the cover o-ring groove. Ensure the o-ring sealing surface is lubricated with “Jack’s 327” or equivalent and that the strainer cover is locked firmly in
position. Lubricant will help to create a tighter seal.
• Check for loose connections on the suction side and tighten the pipe/union connections. Note: Any self-priming pump will not prime if there are suction air
leaks. Leaks will result in bubbles emanating from the return fittings on the pool wall.
• Check for leaking O-ring or packing glands on valves. Tighten, repair, or replace the valves.
• The strainer basket or skimmer basket may be loaded with debris. Remove the strainer housing cover or the skimmer cover. Clean the basket, and refill
the strainer housing with water. Tighten the cover.
• The suction side may be clogged. Contact a qualified repair professional. You should have 5” - 6” of vacuum at the strainer cover (your pool dealer can
confirm this with a vacuum gauge). You may be able to check by removing the skimmer basket and holding an object over the bottom port with the skim-
mer full and the pump running. If no suction is felt, check for line blockage:
• If the pump develops a vacuum, check for a blocked suction line or a dirty strainer basket. An air leak in the suction piping may be the cause.
• If the pump does not develop a vacuum and the pump has sufficient “priming water”:
• Re-check the strainer housing cover and all threaded connections for suction leaks. Check if all system hose clamps are tight.
• Check voltage to ensure that the motor is rotating at full rpm’s.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
12
• Open the housing cover and check for clogging or obstruction in suction. Check the impeller for debris.
• Remove and replace the shaft seal only if it is leaking.
Low Flow
• Clogged or restricted strainer or suction line. Contact a qualified repair professional.
• Undersized pool piping. Correct the piping size.
• Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Sand filters – backwash as per manufacturer’s instructions; D.E.
filters – backwash as per manufacturer’s instructions; Cartridge filters – clean or replace the cartridge.
• Air leak in suction (bubbles issuing from return fittings). Re-tighten the suction and discharge connections using PTFE tape. Inspect other plumbing con-
nections, and tighten as required.
• Plugged, restricted, or damaged impeller. Replace the impeller including a new seal assembly.
Noisy Pump
• Air leak in suction piping, cavitations caused by restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge
return lines. Correct the suction condition or throttle return lines, if practical. Holding your hand over the return fitting will sometimes prove this, or by
putting in a smaller eyeball fitting.
• Vibration due to improper mounting, etc. Mount the pump on a level surface and secure the pump to the equipment pad.
• Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause. Clean the pump housing.
• Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage, which will allow chlorinated water to seep
into bearings wiping out the grease causing bearing to whine. All seal leaks should be replaced at once.
Maintenance, Storage and Winterization
Maintenance
• Clean strainer basket regularly. Do NOT strike basket to clean. Inspect strainer cover gasket regularly and replace as necessary.
• Hayward pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.
• Keep motor clean. Insure motor air vents are free from obstruction to avoid damage. Do NOT use water to hose off motor.
• Occasionally, shaft seals must be replaced, due to wear or damage. Replace with genuine Hayward seal assembly kit.
Storage / Winterization
WARNING – Separation Hazard. Do not purge the system with compressed air. Purging the system with compressed air 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.
Winterization
• Drain water level below all inlets to the pool.
• Remove drain plugs and strainer cover from strainer housing.
• Disconnect pump from mounting pad, wiring (after power has been turned OFF), and piping.
• Once the pump is fully drained of water, re-install the strainer cover and drain plugs. Store pump in a dry area.
