GENERAL SAFETY REGULATIONS

• The machines indicated in this Manual are especially designed for the pre-filtering and recirculation of water in swimming pools

• Install them in line with the specific instructions for each installation

- All modifications to the pump require prior authorisation from the manufacturer. Original spare parts and accessories authorised by the manufacturer ensure greater safety. The pump manufacturer is exempt from all liability regarding any damage caused by

unauthorised spare parts or accessories.

- When working on each machine or on the units linked to them, disconnect the unit from the power supply and the startup devices, as the electrical parts of the pump are live during operation.

- All assembly and maintenance work must be carried out by qualified and authorised personnel who have carefully read the installation and service instructions.

- To guarantee safety when operating the machine, you must comply with that set out in the installation and service instructions.

- In the event of defective operation or faults, contact your supplier or nearest representative.

- If the power supply cable is damaged, the manufacturer, its after-sales service of qualified technicians, should replace it in order to avoid hazards.

- The device should be connected to electricity outlet with earth connection, protected by a Residual Current circuit breaker that does not exceed 30 mA.

- Make sure that water is unable to enter the motor or the live electrical parts.

- Avoid contact at all times - even accidentally - with moving machine parts while the machine is running and/or before it comes to a complete standstill

- Wait for the machine to come to a halt before handling it.

- Before any electrical or mechanical maintenance operation, disconnect the unit from the power supply and block the start-up devices.

• To reduce risk of injury, children should not use this product.

- Do not bury the electric cable. Lay the cable so it cannot be damaged by machinery, like mowing machines, etc.

- Do not start the pump before it is correctly connected to the swimming pool.

- To reduce risk of electric shock, change the electric cable immediately when damaged.

- To reduce risks of electric shock, do not use extension cables to connect the p mp to a power supply. Connect it to a correctly installed electricity outlet.

- Do not use the pump without water!

INSTALLATION

- Only authorised and qualified personnel should install the pump and its cabling, respecting the current legislation.

- The pump should be installed horizontally, screwing it to the support, to avoid vibration and unwanted noise.

- The pump should be installed far from any corrosive or flammable products.

- The pump should have sufficient drainage to avoid risk of flooding and should be protected from excessive humidity.

- Install independent water inlet and outlet valves.

- Allow for sufficient access space for pump maintenance and make sure that the technical plate of the pump is visible.

- During the installation of the pump, position it so there is 1 meter of free space around it.

ELECTRICAL INSTALLATION

- Place the motor on the floor before connecting it to the mains. Otherwise, the motor could cause a serious and even mortal electric shock. Do not place it on the floor over a gas pipe.

• To avoid a dangerous or mortal electric shock, disconnect the power supply of the

motor before working on the electrical connections.

- If it short-circuits, this will indicate there is an electricity problem. If it short-circuits and cannot be restarted, ask a qualified electrician to verify and repair the electrical system.

•The unit should be connected to an alternating current supply (see data on the pump's plate) with an earth connection, protected by a residual current device (RCD) with a rated residual operating current that does not exceed 30 mA.

- Unsuitable mains connections involve the risk of electrocution.

- The power supply should exactly correspond to the voltage indicated on the plate of the motor. Incorrect voltage could provoke a fire and/or damage the motor, and would cancel the guarantee. In case of doubt, check with an electrician.

- The electric cable is included and comes with a "Y" connection. If it is necessary to replace the electricity cable, the new cable should also be of the appropriate type.

The guarantee will be cancelled in the case of any unauthorised modification of the components.
