Important Electrical Notice

The electrical installation must be done by a qualified electrician.

Each pump requires a circuit breaker to separate the pump from the electrical supply.

The contact separation must provide full disconnection on all poles under overvoltage category III conditions.

If the pump is installed on a swimming pool or pond situation, it is mandatory that an earth leakage circuit breaker with a rated tripping current of not more than 30mA be installed.

Check the pump’s name plate for the following: Voltage, amperage draw and cycle.

The power cord, including earth wire, shall have a quality of H07RN-F for models greater than 1kW power input.

For models less than 1kW input, the quality shall be of H05RN-F.

All installations must comply with local codes, based on IEC 60364-7-702 requirements.

Location

The pump must be located as close as practical to the pool. The pump must also be in a position that enables easy access for periodic servicing.

Care must also be taken to position the pump in an area that is free from flooding in a well ventilated and dry area. The pump cooling fan must have a minimum clearance of 150mm.

Installation

We use the latest technology when designing and manufacturing out pumps. A few simple precautions during installation will ensure years of trouble-free operation.

1. The pump suction line should be no smaller than 40mm in diameter (1 ½“).
2. The suction line is to have as few bends or elbows as possible. There must not be an air trap on the suction line.
3. Use only the barrel unions supplied with the pump.
4. Bolt the pump to the required position to prevent movement.
5. The pump electrical cable must be rated for the correct voltage and duty in accordance with local wiring regulations.
6. All wiring and electrical work should be carried out by qualified electricians in accordance with local regulations.
7. The pump motor must be earthed.
8. The weight of the plumbing, pipework and fittings must be independently supported and not carried by the pump or unions alone.
9. The pump motor cooling fan must have a minimum clearance of 150mm.

Electrical Connection

Check that the information on the nameplate corresponds to the power supply.

Employ a competent electrician to ensure wiring installation is made in accordance with any local/national rules in the country where the pump is installed.

The national wiring guidelines in the United Kingdom is BS7671:2018+A2:2022.

Three phase motor variations do not come with an internal thermal protector and require a fused disconnect switch or circuit breaker.

Install and set the safety devices according to the current stated on the nameplate.

Single phase motor variations have a built-in thermal overload switch.

Three Phase Motor

Three-phase motors require a starter switch or magnetic starter with correctly sized overload protection in addition to the fused disconnect switch. Check the rotation direction of three phase motors.

The motor is only suitable for clockwise operation when viewed from the motor end (the end with the fan).

Three-phase motors could rotate in either direction. Changing any 2 of the wires of the cable on a three-phase motor will reverse the direction of rotation. To check the direction, turn the pump on briefly (one second). If it is running in the wrong direction, turn off the power, interchange any two wires at the supply terminals, and repeat the above step to check once more.

When installation three phase pumps, a separate device must be available for permanent installation. This is so that the pump can be completely isolated from the mains power. A contact distance of 3mm per pole is required for both three-phase and single-phase models. Motor protection MUST be installed corresponding to the nominal current of the motor – SEE

VALUE ON RATING PLATE.

It is the responsibility of the installer to ensure adequate protection between the motor and the power supply.

The installer must protect all three phases on the supply of the motor so that the pump cannot run on 1 or 2 phases only.

Warning :

Before disconnecting electrical connections, shut off the electricity at its source.

Priming

The pump will self-prime providing that the strainer basket bowl is full of water and there is sufficient supply from the suction point.

If you lose water from the filter bowl, it will be necessary to prime before starting:

1. Remove the clear lid and fill the strainer bowl with water.
2. Replace the lid ensuring the o-ring is correctly seated to prevent leaks and re-start the pump.
3. Allow a few minutes for the pump to start delivering water

Warning :

High suction lift or long suction lines will require additional time to prime and can severely affect the performance of the pump. If the pump will not prime, repeat steps 1 and 2 above

Warning:

Mechanical seals, if allowed to run dry, can be damaged rapidly and may need to be replaced.

Do not allow the pump to run dry.

Ensure there is always water in the strainer bowl before starting the pump.

If you are unable to prime the pump, please see the trouble-shooting guide.

Ensure all suction and discharge valves are open before you start the pump. Operating the pump with valves shut can damage the pump.

Maintenance

The strainer basket should be inspected and cleaned at regular intervals.

1. Remove the lid and lift out the strainer basket.
2. Remove debris. Hose off with clean water if necessary.
3. Inspect the lid gasket. Replace it if damaged. Lubricate lightly with silicon grease if needed.
4. Replace the strainer.
5. Re-prime the pump.
6. Correctly locate the lid o-ring.
7. Replace the lid – hand tighten only.
8. Switch on pump.

Cold Temperatures

Warning:

In climates where the pump may be exposed to frost or freezing temperatures, care must be taken to ensure the pump is protected from damage.

If the pump is not used during this winter period, we recommend that it is drained completely.

Drain plugs are supplied for this purpose – leave them out over winter. Store the drain plugs in a safe place until they are required again – for example inside the strainer basket.

If possible, remove the pump and store in a dry place for winter.

When you re-activate the pump, ensure all seals and o-rings are in operation condition and lubricate if necessary. Replace if unsure of condition.

Check that the motor shaft turns freely before restarting the pump.

Fluid temperature

The permissible fluid temperature is greater than 0°C and less than 45°C. The pump should never be operated outside of these temperatures or damage will occur.
