Energy Efficiency Overview
The energy consumed by a pool pump is measured in Watts (W) or Kilowatts (kW). The Max-Flo VS displays power consumption in Watts. Power consumption is greatly affected by the speed of the pump; lowering the speed can drastically reduce power consumption.
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 pump speed, consider minimum requirements for proper sanitation and equipment/water feature functionality. It is recommended to filter all pool water at least once every 24 hours. Running the pump at a lower speed may require a longer run time to meet turnover requirements. Equipment like heaters and chlorinators require minimum flows to operate correctly.
Installation and Wiring
WARNING - This product should be installed and serviced only by a qualified professional.
4.1. Pump Location
Locate the pump as close to the pool as practical, running suction lines as direct as possible to reduce friction loss. Suction lines should have a continuous slope upward from the lowest point. Joints must be tight. 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 the pump and filter in the shade to shield them from direct heat. Select a well-drained area that will not flood when it rains. Do NOT install the pump and filter in a damp or non-ventilated location. Keep the motor clean, ensuring free circulation of air for cooling.
4.2. Pump Mounting
Install the pump on a level concrete slab or other rigid base, meeting all local and national codes. Secure the pump to the base with screws or bolts to reduce vibration and stress on pipe joints. The base must be level, rigid, and vibration-free.
Pump mount considerations:
- 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 the pump and piping.
4.3. Pipe Sizing Chart
This chart provides maximum recommended system flow rates by pipe size:
Pipe Size in. [mm] | Maximum Flow Rate GPM [LPM] | Minimum Straight Pipe Length "L" in. [mm] * |
---|---|---|
1 1/2" [50] | 45 [170] | 7 1/2" [190] |
2" [63] | 80 [300] | 10" [254] |
2 1/2" [75] | 110 [415] | 12 1/2" [317] |
3" [90] | 160 [600] | 15" [381] |
Note: It is recommended that a minimum length of straight piping (shown as “L” in the diagram), equivalent to 5 pipe size diameters, be used between the pump suction inlet and any plumbing fittings (elbows, valves, etc.).
Diagram shows a pipe with a label 'L' indicating the minimum straight pipe length required.
When installing the Max-Flo VS, ensure proper pipe and equipment sizing to handle the maximum flow required. Set the maximum speed to not exceed the maximum flow rate.
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
- Use Teflon 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 Teflon 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. Tighten fittings enough to prevent leakage. Tighten by hand and then use a tool to engage fitting an additional 1 1/2 turns. Use care as friction is reduced; do NOT over-tighten or you may cause damage. If leaks occur, remove connector, clean off old Teflon tape, re-wrap with one to two additional layers of Teflon tape, and re-install connector.
- 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
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.
4.5. Electrical Specs
- Voltage: 230VAC, 60Hz, Single Phase
- Amps: 5.9
- Speed Range: 600-3000 rpm
Use copper conductors only. For indoor and 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.
4.6. 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 V) or more than 110% (253 V) of rated voltage (230 V) when pump is running at full load, consult the power company.
4.7. Grounding and Bonding
- Install, ground, bond, and wire pump in accordance with local or national electrical code requirements.
- Permanently ground pump. Use green ground screw provided in wiring compartment; use size and type wire required by code. Connect ground screw to electrical service ground.
- Bond pump to pool structure. Bonding connects 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.
- 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
WARNING - All electrical wiring MUST conform to local codes, regulations, and the National Electric Code (NEC).
- Pump MUST be permanently connected to circuit. If other lights or appliances are also on the same circuit, add their amp loads before calculating wire and circuit breaker sizes. Use the circuit breaker as the master On-Off switch.
- If replacing an existing pump controlled by a separate mechanical time clock, connect the Max-Flo VS pump 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. Set the time clock to power equipment during cycles when the Max-Flo VS pump operates at an appropriate flow rate (see section 6.6 for details).
4.8. Remote Control Wiring / Operation
Max-Flo VS can be controlled in various ways:
- Max-Flo VS (SP2302VSP) can operate in stand-alone mode using built-in programmable timers.
- Max-Flo VS (SP2302VSPND) can communicate with and be controlled by Hayward pool and spa controls. See section 5.2 for more information.
4.9. Digital Control Interface Orientation
The Digital Control Interface can be rotated to front and rear positions after installation. Loosen the four screws securing the interface to the motor drive, lift the interface, rotate it to the desired position, and tighten the screws. Be careful to avoid placing excess strain on wires. Ensure the o-ring that seals the interface to the motor drive is clean and properly located before reattaching.

Startup & Operation
6.1. Prior to Start-Up
If a water pressure test is necessary before initial use, maintain the following criteria:
- Have a professional perform the test.
- Ensure all Hayward pump and system components are removed from the system prior to performing the test.
WARNING – If circulation equipment must remain in the plumbing system during water pressure test, do not apply more than 10 psi pressure. Release water pressure using the filter manual air relief valve before removing pump strainer cover.
WARNING - All suction and discharge valves MUST be OPEN, as well as the filter air relief valve (if available) on the filter, when starting the circulating pump system. Failure to do so could result in severe personal injury.
6.2. Starting/Priming the Pump
For SP2302VSP, refer to section 6.6 for priming time selection.
Fill strainer housing with water to the suction pipe level. If water leakage occurs, DO NOT start the pump. If no leakage occurs, stand at least 10 feet from the 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 the 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.
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:
- STOP PUMP before proceeding.
- CLOSE VALVES in suction and outlet pipes.
- RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See filter owner's manual for more details.
- Remove strainer cover and fill strainer housing with water.
- Clean and lubricate strainer cover O-ring with "Jack's 327" if necessary.
- Replace strainer cover on strainer housing.
Note: Tighten strainer cover lock ring by hand only (no wrenches).
- OPEN VALVES in suction and outlet pipes.
Turn on power and wait for pump to prime, which can take up to ten (10) minutes. Priming time depends on vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within 10 minutes, stop motor and determine cause. Ensure all suction and discharge valves are open when pump is running. See Troubleshooting Guide.

Troubleshooting
11.1. General Problems
Motor Will NOT Start:
- Make sure terminal board connections agree with the wiring diagram on the pump data plate label.
- Be sure the pump is wired for the available field supply voltage (230VAC).
- Check for and correct any improper or loose wiring connections; open switches or relays; tripped circuit breakers, or blown fuses.
- Manually 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 connections.
- If the pump experiences an intermittent power failure short enough to remain power to the controller but not the pump, the pump will stop the motor. To resume function, PRESS the RUN / STOP key or cycle power long enough to turn the controller off.
Motor Hums, But Does NOT Start:
- Impeller jammed with debris. Have a qualified repair professional open the pump and remove the debris.
Pump Won't Prime:
- Empty pump/strainer housing. Ensure 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 gasket sealing surface is lubricated with “Jack's 327" and that the strainer cover is locked firmly in position. Lubricant helps create a tighter seal.
- Loose connections on the suction side. 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.
- Leaking O-ring or packing glands on valves. Tighten, repair, or replace the valves.
- Strainer basket or skimmer basket 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.
- Suction side clogged. Contact a qualified repair professional. You should have 5" - 6" of vacuum at the strainer cover. You may be able to check by removing the skimmer basket and holding an object over the bottom port with the skimmer 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. 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 - Generally:
- 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 Teflon tape. Inspect other plumbing connections, 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.
Interference With Home Automation/Power Line Communication Equipment:
- Make sure the terminal board connections agree with the wiring diagram on the pump data plate label.
- Check for and correct any improper or loose wiring connections.
- Install noise filter (from home automation/power line communication equipment vendor) to prevent equipment interference.
11.2. Error Codes
If an internal issue is detected, the drive will turn the motor off and display "Err" and the corresponding error code. If more than one error is detected, the screen will cycle between errors. Investigate and resolve the cause before resuming operation. Press RUN/STOP or cycle power to resume.
Code | Description | Troubleshooting |
---|---|---|
01 | DC bus voltage too low | Remove power for at least 1 minute and verify line voltage is within 10% (207 – 253 VAC) of pump rated voltage at the terminal block. Also, verify power supply connections are properly made at the circuit breaker and terminal block. |
02 | DC bus voltage too high | Remove power for at least 1 minute and verify line voltage is within 10% (207 – 253 VAC) of pump rated voltage at the terminal block. |
03 | AC mains voltage too low at startup | Verify line voltage is within 10% (207 – 253 VAC) of pump rated voltage at the terminal block. Also, verify power supply connections are properly made at the circuit breaker and terminal block. |
04 | Motor drive module temperature too high | Check motor airflow path for obstructions and clear if present. Check ambient temperature and verify against motor nameplate (40°C / 104°F). |
05 | Motor temperature too high | Check motor airflow path for obstructions and clear if present. Check impeller, diffuser, shaft seal, and motor for any issues or binding. Check ambient temperature and verify against motor nameplate (40°C / 104°F). |
07 | Motor current too high | Check impeller, diffuser, shaft seal, and motor for any issues or binding. |
10 | Motor current measurement has failed permanently | Indicates that motor/drive may need to be replaced. |
20 | Motor overload during start up | Check impeller, diffuser, shaft seal, and motor for any issues or binding. |
64 | Internal short circuit failure | Indicates that motor/drive may need to be replaced. |
97 | Multiple errors encountered at the same time | Perform checks associated with other error codes. |
98 | Display is unable to communicate with motor drive | Check cable between display and drive for proper continuity and correct placement of each conductor. |
Note: If troubleshooting steps do not resolve the error, the problem may be internal to the motor/drive. Contact your local Hayward Authorized Service Center (HASC) for more information.
