You have just become the owner of a sand filter, its base and its valve.
Your filtration system uses a special sand designed to trap impurities in the pool water. The sand is poured into the tank and
acts as a permanent filtration system. The pump draws in the unfiltered pool water, which contains impurities in suspension,
and feeds it to the multi-way control valve. When the water flows through the sand, the impurities are trapped there and the
water that returns to your pool is filtered.
1. Filter location
Provide a clean, level location The top of the filter must be no more than 1.5 m above the water level. Position the filter so
that the pipes, valve and drain plug are easily accessible. Servicing and wintering will then be easier.
2. Pump assembly
Attach the pump and its support to the filter according to the manufacturer's instructions.
3 SIDE filter (valve on the side, Fig. 1):
Install the valve, taking care to ensure that the O-rings are correctly seated and screw in the nuts by hand until the valve/
filter assembly is airtight.
Remove the cover and fill the filter with water up to one third. Cover the diffuser to prevent sand from entering it. Then fill the
filter with the quantity of sand indicated (2/3 to 3/4 of the height) and remove the diffuser protection. Clean off any remaining
sand and put the cover back in place. Connect the pipes to the valve. The pump must be connected to the "PUMP" input,
the water return to the "RETURN" output and the drain to the "WASTE" output.
Note 1: Do not use force when screwing the connection end-pieces into the valve fittings.
Note 2: Cover the male threads with teflon tape.
Note 3: We advise you to put a layer of gravel (grain size 3 to 5 mm) up to the level of the laterals (covering them) and
then insert the filtering media up to 2/3 to 3/4 of the filter height. The layer of gravel ensures better drainage and facilitates
backwashing.
IMPORTANT: ALWAYS STOP THE PUMP BEFORE OPERATING THE MULTI-WAY VALVE.
1. Check that all connections are tight and that the filter contains just the right amount of sand.
2. Set the valve to "BACKWASH". Always lower the handle before turning.
3. Start the pump as indicated by the manufacturer's instructions. Check that water is flowing normally within the circuit.
WARNING: All suction and discharge valves must be open when the pump is started. Otherwise, there is a risk
of damage to property, serious injury, or death.
Once the water is flowing smoothly, let the pump run for at least another 2 minutes. This backwash is recommended to
eliminate any impurities or fine particles from the filtering sand.
4. Stop the pump and set the valve to "RINSE". Restart the pump and let it run until the water becomes clear in the valve
circulation sightglass (about a minute).
5. Stop the pump and set the valve to "FILTER". Restart the pump and filtering will start.
Adjust the inlet and outlet valves for the desired water flow.
6. Carefully note the pressure reading at that time and the position of the needle on the pressure gauge. As the filter
operates, impurities are retained and the pressure increases in the tank.
When it exceeds the initial pressure (clean filter) by 10 PSI (0.7 bars or kg/cm 2 ), the filter must be backwashed.
Note 1: When your pool water is cleaned for the first time, it may be necessary to backwash the filter frequently: it is likely
to contain a significant quantity of impurities.
Note 2: Clean the strainers of the pump and skimmers regularly to ensure trouble-free operation of your filtration system.
