WARNING – Pool and spa components (seals, gaskets, etc.) have a finite 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 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 the 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 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 including, but
not limited to, grounding, bonding and other general wiring procedures.

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
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 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 isolated
from 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.

2.3. Product Dimensions
3. Energy Efficiency Overview
The energy consumed by a pool pump is measured in terms of Watts (W) or Kilowatts (kW). The TriStar VS 950 Variable
Speed Pump displays power consumption in Watts. Given this information, you can determine the cost of operating the
pump:
Power consumption of pump X Cost of electricity = Cost of Pump Operation per Hour
Example: TriStar VS 950 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

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 8 of 36 TriStar VS 950 Variable Speed Pump IS32950VSP Rev B
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.
Benefits of running at low 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.
4. Installation and Wiring
WARNING – This product should be installed and serviced only by a qualified professional.
4.1. Pump Location
Locate pump as close to pool as practical and run suction lines as direct as possible to
reduce friction loss. 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.
4.2. 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 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.

2 ½” [75] 110 [415] 12 ½” [317]
3” [90] 160 [600] 15” [381]
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 TriStar VS 950, 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. See section 6.6 item #7.
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.
4.4. Plumbing
1. Use PTFE tape to seal threaded connections on molded plastic components. All plastic fittings must be new or
thoroughly cleaned before use. NOTE - 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 portion 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.
4.5. Electrical
WARNING – All electrical wiring MUST conform to local codes, regulations, and the National Electric Code
(NEC).
WARNING – Ground and bond pump before connecting to electrical power supply. Failure to ground and
bond pump can cause serious or fatal electrical shock hazard. Do NOT ground to a gas supply line. To avoid
dangerous or fatal electrical shock, turn OFF power to pump before working on electrical connections. Fire Hazard -
match supply voltage to pump nameplate voltage. Insure that the electrical supply available agrees with the pump’s
voltage, phase, and cycle, and that the wire size is adequate for the amps rating and distance from the power
source. Use copper conductors only.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 10 of 36 TriStar VS 950 Variable Speed Pump IS32950VSP Rev B
4.6. Electrical Specs
1. Voltage: 230VAC, 60Hz, Single Phase
2. Amps: 10.9
3. Speed Range: 600-3450 rpm
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.
4.7. 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.
4.8. 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.
4.9. Wiring
WARNING – All electrical wiring MUST conform to local codes, regulations, and the National Electric Code
(NEC).
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. If the TriStar VS 950 pump is being used to replace an existing pump that was controlled by a separate
mechanical time clock, the TriStar VS 950 pump should be connected directly to the line power supply,
bypassing the time clock. The time clock can then be used to power other equipment (such as a heater, heat
pump, or booster pump) that requires the filter pump to be operating when used. If the time clock is used in this
manner, it should be set to power the equipment during a time cycle when the TriStar VS 950 pump is operating
at an appropriate flow rate to operate the other equipment, as defined by the timers set in the Timer Menu. See
section 6.7

determine Hayward control software revision, consult the appropriate Hayward pool control installation manual or
visit our website at www.haywardpool.com. Connection wire must be rated for a minimum of 300V, and may be up to
500 feet in length. Use removable 2-position terminal block connector for wiring connection to motor drive board
taking care to note the wire colors and corresponding numbers next to the connectors. Do not connect to the upper
input terminals shown as light gray above.
Once installed, Remote Control Mode must be set to Standalone/Hayward in the pump Configuration Menu (see
section 6.6), and for all controls other than OmniLogic, Comm Bus Address must be set according to instructions
provided in the Hayward pool control installation manual (see section 6.6.11). It is best to leave the max/min
allowed speeds in the pump configuration menu set to their factory defaults to prevent conflict with these settings in
the Hayward pool control configuration menu. Preset Speeds 1-4 and Quick Clean are disabled when the pump is
remotely controlled. Prime Duration is disabled only when the pump is communicating with a Hayward pool control.

5.4. External Relay Speed Control Wiring (For remote selection of pump speed)
Note: For third party controls and Hayward controls that are NOT software compatible.
Figure 5.4-1
Connection wire must be rated for a minimum of 300V. See section 6.6.11 for more details. Do not connect to the
lower “COMBUS” or wall mount “DISPLAY” data terminals.
The TriStar VS 950 pump can also be controlled from third party pool controls using relay contacts to select the
speeds set in the Timer Menu (see section 6.7). In addition to this section you may also consult the third party pool
control installation manual for electrical connection details. Once installed, Remote Control Mode must be set to
Relay Control in the pump Configuration Menu (see section 6.6). Preset Speeds 1-4 and Quick Clean are disabled
when the pump is remotely controlled. When Inputs 1-3 are activated via the pool control relays, timer speeds 1-8
are selected according to the following table:

The number of speeds available depends on the number of auxiliary relays used as noted below:
1. Filter pump relay plus 1 auxiliary relays allows control of 2 speeds
2. Filter pump relay plus 2 auxiliary relays allows control of 4 speeds
3. Filter pump relay plus 3 auxiliary relays allows control of 8 speeds

5.5. Remote Stop Switch Wiring (Optional)
Figure 5.5-1
Connection wire must be rated for a minimum of 300V. Switch must be latching type; pump is stopped when circuit
is closed.
6. Startup & Operation
6.1. 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.
6.2. Starting/Priming the Pump
Refer to item #9 in section 6.6 for priming mode selection.
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. Running pump dry may damage seals, causing leakage, flooding, and
voids warranty. Fill strainer housing with water before starting motor.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 18 of 36 TriStar VS 950 Variable Speed Pump IS32950VSP Rev B
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, unscrew and 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 clockwise to tighten cover.
Note: Tighten strainer cover lock ring by hand only (no wrenches).
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. See
Troubleshooting Guide.
