DANGER
If this instruction is not heeded, there is a risk of injury to
persons.
ATTENTION If this instruction is not heeded, there is a risk of damaging the
equipment or the installation.
1.1 Basic advice on safety and prevention of damage
ATENCIÓN leer atentamente las instrucciones
It is essential that both the fitter and the user should read the manual and equip-
ment instructions before fitting and start-up, in order to ensure their own safety, the
safety of other persons and the optimum operation of the equipment.
The user must keep the manual and the safety labels in good condition for
subsequent use.
DANGER, risk of electrocution
Take maximum precautions when handling the equipment, since it is connected to
the mains and it contains water (an excellent conductor of electricity).
Before performing any operation on the pump, it is essential to disconnect the
power supply.
DANGER power cable
Position the power cable so that it cannot be trodden on, perforated or damaged
with any object situated near it.
Carry out the installation in accordance with the safety instructions for swimming
pools and the particular instructions for the pump and selector valve (supplied with
the respective manuals).
The safety regulations in effect must be observed when installing the equipment.
Maximum pressure of the equipment 2,5bar. Do not connect directly to the drinking
water mains.
PROHIBITED handling or repair
The equipment may only be handled or repaired by official technical services.
The user may only handle the equipment as indicated in this manual.
The manufacturer accepts no responsibility for any other handling of the equipment
by the user.
ATTENTION cleaning
Always clean with a damp cloth and a neutral soap solution.
Do not use products that contain solvents or acids.
ATTENTION heat
Position the unit away from heat sources or exposure to the sun.
The equipment has been designed for operation in technical premises.
ATTENTION
Only use the equipment for the filtration of water in domestic swimming pools or
small ponds
The equipment has been designed for operation with clean water and the
temperature must be below 35ºC.
ATTENTION ventilation
Install the unit in such a way that its position does not prevent the flow of air in and
out of the ventilator part of the pump. It must not be installed inside furniture or
cupboards which prevent the free flow of air around the unit.
beside a paragraph, they indicate the

Do not start the pump connected to the pool bottom cleaner, if the latter is not
immersed in water.
Do not run the pump dry. The water level of the swimming pool must not be lower
than that of the skimmer.
ATTENTION periods when not in use
When the unit is not to be used over a period of time, disconnect the current collec-
tor on its base. Take special care to close the shut-off valve through which water is
supplied to the filtration unit and to empty the water contained in the filter and pump.
2. GENERAL OBSERVATIONS
The filtration unit is an essential device for maintaining the quality of the water in a swimming
pool over a long period of time, both for the convenience of bathers and to save water
consumption, since the water does not need to be replaced. The function of the unit is the
mechanical separation of the solid particles in the swimming pool water: these are retained in
the filtering medium.
The filtering element consists of small grains of silicon sand, which are capable of retaining the
dirt dissolved in the water.
As the water is filtered, the dirt adheres more and more to the grains of sand, reducing the
passage of water and consequently the volume of water in the swimming pool.
In order that the water is correctly regenerated, it is recommended that the entire contents of the
swimming pool are filtered at least 4 times a day
To perform the functions indicated, the unit is principally formed of the filter, the pump and the
selector valve. The selector valve may have 4 or 6 positions, depending on the number of
functions of each equipment unit. The filtration unit has been designed to comply with the EN
16713-1 standard.
2.1 Principal functions
ENSURE THAT THE PUMP IS NOT IN OPERATION BEFORE CHANGING THE
POSITION OF THE VALVE.
2.1.1 Filtration
This consists in recirculating the water of the swimming pool from the skimmer and overflow,
driving it by means of the pump through the filter and returning the filtered water to the
swimming pool.(Fig.1)
The operating time of the equipment depends on the volume of water in the swimming pool and
the filtration capacity of the equipment (flow). See point (3.5.) Start-up.

2.1.2 Pressure control

The pressure gauge permits control of filter pressure. It is important to check the pressure at
regular intervals to ensure optimum equipment operation.
When the pressure increases by 0,5kg/cm² in relation to the initial reading the filter is reaching
saturation point, thus reducing filtering capacity. When the pressure shows such an increase the
washing process must be carried out. It is therefore important to observe and note down the
pressure at first start-up.
The use of certain swimming-pool accessories, such as the bottom-suction device, can reduce
filtering effectiveness and lead to gradual saturation of the filter.
2.1.3 Washing
If the filter is saturated, it must be washed. This consists of 2 stages:
a) Backwashing: countercurrent circulation of the water through the filter and towards the
outflow for approximately 3 minutes. (Fig.2)
b) Rinsing: circulation of water through the filter towards the outflow, until the water is clear. (See
inspection window). In the absence of a window, perform this operation for ½ - 1minute.(Fig.3)
2.1.4 Recirculation – Bypass (only for units with 6- position valves)
When the selector valve is in this position, the water from the pump is recirculated directly
towards the swimming pool, without passing inside the filter. Ensure that the pump is not in
operation, turn the valve to the "RECIRCULATION" position and start up the pump.
To apply this process during the chemical treatment of the water.(Fig.4)
