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.

Principal functions

ENSURE THAT THE PUMP IS NOT IN OPERATION BEFORE CHANGING THE POSITION OF THE VALVE.

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.

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.

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)

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)

Emptying (only for units with 6-position valves)
If the swimming pool does not have an outflow at the bottom, it can be emptied by means of the equipment pump. This function can also be used to remove large particles of dirt from the bottom of the pool with the pool bottom cleaner; in this way the dirt will not pass through the filter. (Fig.5)

Closed (only for units with 6-position valves)
In this position all the functions are interrupted. This is used to carry out maintenance work on the filtering tank. (Fig.6)

INSTALLATION AND START-UP

Typical installation diagram. (Fig.7)

Fitting instructions

• Installation must be carried out in accordance with the safety standards for swimming pools, especially standard EN 60364-7- 702 and the particular standards for each application.
• For the safety of persons, it is imperative that the filtration unit is installed at a distance of at least 3.5m from the swimming pool and in compliance with the regulations in force. If it is installed less than 3.5m from the swimming pool, use of this equipment is prohibited while the pool is being used.
• The pump must be installed in accordance with the instructions in the installation manual or in the user manual.
• The surface on which the filter is fitted must be horizontal and completely flat.
• It must be fitted in a permanent location and, whenever possible, below the water level of the swimming pool.
• The maximum admissible pressure is 2,5bar (36 Psi); to avoid overpressure in the use of the equipment, it must not be fitted at a depth of more than 4m below the water level of the swimming pool or connected to the public water mains.
• The room or hut where the filter is located must have a drain, in order to avoid the risk of flooding that would affect the safety of the electrics and of persons.
• It is recommended that around the filter there should be sufficient space in order that the inspections, checks and maintenance required may be carried out.
• PVC accessories must be used for the connections between the piping and the selector valve, pump, etc.
• The connections must be made watertight by means of seals and it is not necessary to tighten screws excessively or use teflon.
• The pipes in the installation must be made of PVC. Under no circumstances should iron accessories or pipes be used, since these could seriously damage the plastic components of the installation.
• Do not load the sand until the initial start-up has been performed.

How to assemble the filtering kits
The steps to follow for assembling the filtering kits are:

• Attach the sand container to the base using the two screws supplied. (Fig.12)
• Attach the pump to the base using the four screws supplied in the indicated order. (Fig.13)
• Add the sand (see point 3.4 in the manual).
• Install the selecting valve and the pressure gauge.
• In order to assemble the flexible connection kit, first connect the PUMP exit-point of the valve and then bend the flexible tube so as to screw the connecting thread into the exit-point of the pump.(Fig.14)

Loading of sand
The sand loaded must correspond to the grading and quantity indicated on the filter specifications plate. Load the sand as indicated below: (Fig.8)

1. Check that the pump is not in operation.
2. Set the selector valve to the “CLOSED” position.
3. Remove the selector valve and fit the funnel as shown to prevent sand from entering the collector unit.
4. Pour water into the vessel until the tank is 1/3 full, followed by the sand. Take care not to damage the collector arms.
5. Fit the valve to the vessel and the pump once again: The area of the watertight seal between the valve and the vessel must be clean and free of sand.
   Take care not to damage the collector arms. Avoid pouring sand inside the central pipe.

Start-up

1. Cleaning: Clean the swimming pool as well as possible before starting up the filtration unit. Remove dirt and foreign bodies from the skimmer siphon and pump prefilter.

2. Priming the suction: Open the pump prefilter cover and completely fill with water up to the level of the suction intake. (Fig.9)
   Close the cover and check that it is correctly fitted.

3. Filtration start-up: Set the selector valve to the “Filtration” position. Turn the equipment on.

4. Bleeding: Remove the air from the inside of the pump, valve and deposit. Slightly open the bleeders available. (Fig.10)
   Close the pump filter cover and bleeders correctly, so that they are watertight.

5. Adjust the hours of operation of the equipment in accordance with the volume of the swimming pool, the flow supplied by the pump and it’s situation. See Table 1.
   After the initial start-up it is recommended to keep the filter running continuously for 24 hours and then to clean the remains of dirt on the pump prefilter and skimmers.

WINTER CARE

In winter the filtering installation must be protected from the risk of frost. (Fig.11)
If the equipment is not going to be used during the winter period, the following operations must be performed:

• Wash the filter in accordance with the instructions.
• Disconnect the equipment from the mains.
• Completely empty all the water from the filter, pump and pipes.
• Set the key on the filter to the “WINTER” position. Once the winter period is over, proceed according to the instructions for the initial start-up.

POSSIBLE PROBLEMS, CAUSES AND SOLUTIONS

1. Presence of algae in the sand which block the filter.
2. Incorrect chemical disinfection of the water.
3. Low water flow.
4. After washing, the filter pressure is high.
5. The filtered water is not clear.
6. The pump does not draw water or the suction time is very long.
7. The pump does not start.
8. The pressure gauge oscillates sharply.
9. The pump loses water.
10. Noise.
