Self-priming swimming pool pump

This manual contains basic information on the safety measures to be adopted during installation and start- up. The fitter and the user must therefore read the instructions before installation and start-up.

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.

ELECTRICITY

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 pump should be powered from an insulated transformer or via a circuit breaker or residual-current device of 30mA maximum.
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.
The electrical installation has to be according to current legislation.
If the electrical cable is damaged, the manufacturer, its agent, or any other qualified person should replace it to avoid any damage.
The pump is equipped with complete thermal protection. Follow the assembly diagram below for correct electrical installation.
The electrical installation should be done by someone qualified in working with electrical equipment. This device is not designed to be used by children, by physically disabled persons or those with reduced sensorial or psychological ability or by persons without experience or knowledge of the device, unless a persons responsible for safety is in charge of their care and provides them with previous instructions for handling the device.
Do not permit children nor adults to sit or lean on the equipment. Children should be supervised to ensure that they do not play with the equipment.
Adjust the value of the thermal relay appropriately depending on the pump current.
Unsuitable mains connections involve the risk of electrocution

Assembly of pipes

The pipes should be assembled before and after the pump and should have diameters equal of above those of the pump inlet.
The suction and expulsion pipes should never stay connected to the pump.
Well seal all the connections and the cover of the pump to avoid possible water leaks into the motor, which could damage it.

Tests before starting the pump
Carry out the following operations before starting the pump:

Check that the power supply as well its frequency correspond to the information of pump specification plate.
Before starting the pump, fill it with water for self-priming of the pump.
Check that the mains voltage and frequency correspond with those indicated on the pump characteristics plate
The pump can continuously work. Starting the pump

Start the pump only when the suction and expulsion tubes are connected to the inlet and outlet of the pump. Check there are no obstacles in the pipes.

Maintenance and cleaning

Your new pump does not need any specific or programmed maintenance In the case that the pump is not used during some time, we recommend dismantling it and cleaning it to be kept in a dry and well-aired place.
If the electrical cable is damaged, the manufacturer, its agent, or any other qualified person to avoid any danger should replace it to avoid any dangers.
Regularly clean your pump, removing any dirt from the filer so the inlet pipe is not blocked or the pump damaged.
Pump components that, due to their normal use, suffer wear and/or tear must be regularly replaced to ensure good pump performance.
For regular control:
Check that the mechanical parts are tightly secured and check the condition of the screws supporting the machine.
Check that the power conductors and isolating parts are in their correct position, are secure and in a good state of repair.
Check the temperature of the machine and the electric motor. In the event of a fault, stop the machine immediately and contact the nearest Technical Assistance Service.
Check for machine vibrations. In the event of a fault, stop the machine immediately and contact the nearest Technical Assistance.

TROUBLESHOOTING

TABLE

Symptoms	Causes	Solution
The pump does not work	There is no power supply	Use another device that works to check the electricity outlet and check the short-circuit switches
	It has short-circuited	Check the short-circuit switches and replace them if necessary
	The automatic thermal cut-out of the pump has activated to protect it.	Cut the power supply and leave to cool before re- starting the pump. Make sure the pump and motor have sufficient ventilation space. Make sure that the pump is not obstructed by dirt and the motor can turn freely
	The motor has burnt out due to a power supply overload or flooding	You may have to change the motor.
The pump works with reduced or no flow	The pump is blocked (check if the motor turns freely)	Blockage in the pump or in the basket
	The valves are closed	Check the system to make sure that the valves are in the correct position for filtering, including the inlet and outlet valves of the pump.
	The filter is full of dirt	Clean the filter
	Air in the system	Start the pump (see starting procedure). Check to see there are no suction air leaks in the pipes or in the connections. Make sure that the lid of the basket is well closed and hermetically sealed. Check there are no leaks under the pump.
	Lack of water	Make sure that the water level is at least at the height of the skimmer.
	Dirt in the pump or in the skimmer. (Note: Do not make the pump work without the pump or skimmer basket correctly assembled.	Make sure the pump or skimmer baskets are not full of dirt. Make sure there is no blockage at the inlet or outlet of the pump or make sure there are no foreign objects in the pump.
Leak between the casing of the pump and the motor.	The screws of the casing are not tightened. The watertight or metallic gasket is worn.	Cut-out the pump and loosen the screws, check the alignment and the condition of the water-tight gaskets before tightening the screws, replace the gaskets if necessary.
