1 DESCRIPTION OF THE PRODUCT AND APPLICATION FIELD.
These filters are the most reliable nowadays in the market for the cleaning and the maintenance of your domestic swimming pool. They find their
application from children to professional's aboveground pools.
Each model is provided of a multifunctional valve that allows the application of the product in many different ways.
In particular the filters do not need special maintenance operations because working directly on the valve they allow their deep cleaning with no need of
long and exhausting operations.
Follow carefully what is reported next so that you will use the filter respecting the most common safety rules and remember that it is necessary to have a
proper pool pump to be able to use the filter.
Always remember that each operation must be done with plug disconnected and that the pump must never work without water.
2 APPLICATION LIMITS.
Maximum water temperature : 35 [°C].
•
Maximum pump's flow rate: 20000 [l/h].
•
Sand type: 0.4÷0.8 [mm] (recommended value).
•
3 USE AND REGULATION.
To be applied the filters must be connected to a pool pump as the type indicated at the Fig. 1.
Furthermore it is possible to couple the pool pump to a skimmer (superficial aspirator) as shown at the Fig. 2 and Fig. 11.
3.1. Positioning.
Before assembling the filter it is better to decide its final position because when it will be refilled with sand it will be hard to move. The distance of the
filter from the swimming pool border should be at least of 3.5 [m].
3.2. The parts that build your filter.
As you can see from the Fig. 3 your filter is formed of many components:
1.
Multifunctional Valve.
2.
Soft O-ring for the sealing between the multifunctional valve
and the tank.
3.
Closing flange.
4.
Funnel.
3.3. Drain Tap assembling.
Before mounting the filter assemble the special water drain tap. (Fig. 4).
The components that form the drain tap are:
9.
Tap Body.
10. Tap's O-Ring couple. One is to be applied internally and the other one externally.
11. Closing Ring.
12. Lid's O-Ring.
13. Lid.
3.4. Filter assembling.
Once the drain tap is mounted on the tank paying attention that all the o-ring are well applied you can proceed with the Filter assembling.
Insert diagonally the tube with the diffuser body inside the filter as shown in the Fig. 5 and subsequently mount the plugs on the diffuser body.
Place the diffuser complete with the tube underneath the tank. Refill the tank with water until the first line you can see on the tank (Fig. 6).
This procedure give stability to the diffuser.
Place the special funnel on the tank's mouth, paying attention to cover properly the tube, and start to pour the quartz sand (not supplied) into the tank
(Fig. 7).
Once you refilled the tank with sand until the higher line (around 2/3 of the tank's height) remove the funnel.
Take now the special valve supplied and insert it applying it under the soft o-ring (Fig. 8).
Clean really carefully the tank's neck, place the valve taking care that the tube enter in the central hole (Fig. 9).
Now fix the valve to the tank through the supplied flange (Fig. 10). Work with a screwdriver to tight the screws.
Take off the multifunction white valve cap,apply some supplied teflon around the manometer (optional for SF25) thread and then screw the manometer
with a key using no strength on the plastic box (Fig. 11). Now your sand filter is at your disposal.
3.5. Connection to the skimmer and to the pump (Fig. 12-13).
Important: apply some supplied teflon around the hosetails to guarantee a safe sealing.
1.
Pressure connection: join the filter pump (OUT) to the multifunction valve (PUMP), using the corrugated pipes or the rigid connection.
2.
Skimmer tube: join the Skimmer connection to the frontal connection of the filter pump.
3.
Return-tube: join the connection on the 4 or 6 ways valve marked with RETURN/POOL to the entrance mouth connection of the swimming
pool. Tight with special hose clamps the tubes on the connections.
4.
Backwash-tube: to be used when we apply the backwash function to drain the dirty water in a discharge area. For the connection use proper
rubber tubes and proper hose clamps.
3.6. Refilling the swimming pool.
If you have already connected everything properly you can now start to refill the swimming pool. The water level must reach at least the middle of the
Skimmer's suction mouth.
3.7. Starting the system.
Before starting the application of the filter make sure this one is well positioned out of the swimming pool under the water level. Check that all the tubes
and joints are fixed tightly.
The swimming pool has to be refilled with water until half of the skimmer height. The water must arrive to the pump by natural flow.
Change the 4 or 6 ways valve lever to the BACKWASH position.
Make sure that on the joint WASTE a tube that make the water drain is connected.
Start the filter only after this moment.
Start the pump and make a backwash of about 2÷3 minutes.
Right after this stop the pump and change the valve lever position on RINSE.
Re-start the pump and rinse for about 30 seconds. Stop the pump once again and change the valve lever position on FILTER.
Start again the pump. The system is now doing its normal job. We suggest to start the filter twice a day for 4 or 5 hours. Make the bottom cleaning with
the valve lever on FILTER position. After each bottom cleaning or when the pressure level shown on the manometer goes up of 2-3 half nicks the
BACKWASH it's necessary.
A rinse of about 30 seconds must follow each BACKWASH.
You can proceed with the bottom cleaning using the proper tools even on WASTE position (only on the 6 ways valve version) to take off all impurities
(for example seaweeds) that otherwise could pass again through the filter's sand. In this position the water is aspirated from the pool's bottom and
directly leaded on the outside.
