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’) [1 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 footrest for such seating areas.
- The maximum system flow rate shall not exceed the f rating as listed on Table 2.
- Never use the Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not attached.
- Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately.
- In addition, two or more suction outlets per pump are installed in accordance with the latest ASME, APSP Standards, and CPSC guidelines, and follow all National, State, and Local codes applicable.
- Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
- Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction outlets can result in an increased potential for suction entrapment as described above.
- Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper, and other material, can result in an increased potential for suction entrapment as described above.
General Points
Install the pump at a suitable distance from the pool to reduce the distance between the suction point and the pump as much as possible to avoid pointless excessive pressure drops on the hydraulic circuit. However, it is essential to comply with the safety distance required by the current installation standard (3.5 metres minimum). Install and use the product at an altitude less than 2000m
The motor requires the air to circulate freely around it to allow natural ventilation. Check regularly that no objects, leaves, or other debris are blocking the motor cooling system. The pump must be installed to ensure that the external disconnection switch incorporated into the fixed unit is visible and easily accessible. The switch must be located near the pump.
The pump must be permanently installed on a concrete base using 8mm lag screws suitable for concrete, screwed into drilled implantation holes. Lock washers must be used to prevent the installation of lag screws from working loose over time. If the pump has to be mounted on a wooden board, Ø 8mm hexagonal wood screws must be used, combined with lock washers to prevent the screws from working loose over time. The acoustic pressure of pumps is less than 70 dBA.
Necessary Measures
- Connect the pump to the earth: Never operate the pump unless it is connected to the earth.
- Connect the pump with a flexible cable 3G1.5mm² for single-phase pumps and 4G1mm² for three-phase pumps, type H07RN-F.
- Include a 30mA differential protection to protect people against electric shocks, which may be caused by a breach of the equipment’s electrical insulation.
- Include short-circuit protection (the rating is determined according to the value given on the nameplate on the motor).
- Include a means of disconnection from the power supply having an opening distance on the contacts of all the poles, ensuring the power supply is completely cut off under the conditions of a category III overvoltage.
Single-phase electric motor
The single-phase motors fitted to our pumps are provided with thermal protection. This protection operates on an overload or in the event of abnormal heating of the motor coil and is reset automatically when the winding temperature drops.
Three-phase electric motor
Check the running direction of the pump motor (a label is provided on the motor housing to indicate the motor running direction). Whatever the motor type, in addition to the devices mentioned above, it is also necessary to install a thereto-magnetic protective device GV2ME or of similar features, calibrated in accordance with the indications on the motor nameplate. The table on page 28 indicates the various characteristics of the motors fitted to our pumps.
Electrical connection
Make sure that the power supply voltage required by the motor corresponds to that of the distribution network and that the power supply cables match the power and current of the pump. All the electric connections of the pump and the possible change of power supply cable must be handled by a qualified professional so as to avoid all possible danger.
When making these electrical connections, refer to the diagram given under the lid of the motor terminal box. Be sure to check the electric connections are tight and sealed before powering up. The pre-wiring that might be included on some of the pumps must be removed for the final connection of the pump to the electric power supply. This pre-equipment is only used for work testing during the manufacturing phases.
Installation
Install the pool pump so as to reduce pressure drops to a minimum whilst complying with the distances specified in the installation standard, namely 3.5m minimum between the pump and the pool. The suction pipe must be installed with a slight uphill incline towards the pump axis. Ensure that the connections are correctly tightened and watertight. However, avoid excessively tightening the pipes. For plastic materials, use Teflon only to ensure watertightness. The diameter of the suction pipe shall depend on that of the discharge pipe. Avoid damp or non-ventilated locations. The 0motor requires the cooling air to circulate freely.
Instructions for Start-Up and Priming
Fill the body of the strainer with water up to the level of the suction pipe. Never run the pump without water, as the water is necessary for cooling and lubrication of the mechanical shutter. Open all the suction and discharge pipe valves, and the filter air purge valve if there is one. (Any air in the suction pipes must be eliminated.) Start up the generator and wait a reasonable time for priming. Five minutes is not excessive for priming (this time depends on the suction head and the length of the suction pipe). If the pump does not start or does not prime, please refer to the troubleshooting guide.
Maintainance
- The motor shaft is mounted on self-lubricating bearings, which do not require any subsequent lubrication.
- Keep the motor clean and dry, and ensure the ventilation openings are not blocked.
- The mechanical seal occasionally starts to leak and must then be changed.
- Apart from cleaning the pool, all repairs, servicing, and maintenance must be carried out by an approved agent or a qualified person.
Estimated life
- Mechanical seal 2 years or 10.000 hours.
- Motor bearings kit 2 years or 10.000 hours.
- Set of gasket (strainer, housing, bulkheads, drain) 2 years or 25.000 hours.
- Capacitor 2 years or 10.000 hours.
Wintering
- Empty the pump by removing all the drain plugs and storing them in the strainer basket.
- Disconnect the pump, remove the pipe connectors, and store the entire unit in a dry, well-ventilated place, or at least take the following precaution.
- Disconnect the pump, remove the 4 bolts attaching the pump housing to the motor bracket, and store the unit in a dry, well-ventilated place. Then cover the pump housing and strainer to protect them.
Troubleshooting
- Check the electrical connections, switches Hayward IS-3000VHC-18 Super II Pump or relays, and the circuit breaker or fuses.
- Ensure that the motor turns freely by hand.
- The cables, connections, relays, etc.
- Voltage drop on the motor (frequently caused by cables that are too small).
- That there is no seizing or overheating (by reading the absorbed current).
- The motor growls but does not start. Check that a phase is not cut, and the capacitor is not damaged.
The pump does not prime
- Ensure the strainer housing is filled with water, that the cover seal is clean and correctly positioned, and that no air can enter. If necessary, tighten the cover lock screws.
- Ensure that all the suction and discharge valves are open and not blocked, and that the suction outlets in the pool are fully submerged.
- Check that the pump draws by freeing the suction as close as possible to the pump.
- If the pump does not draw despite being sufficiently full of priming water
- Tighten the bolts and pipe accessories on the suction side.
- Check the voltage to ensure that the pump is rotating at the correct speed.
- Open the pump and check that nothing is blocking it inside,
- Replace the mechanical shutter.
- If the pump is drawing normally, check the suction pipe and strainer, which may be blocked or allowing air to enter.
