HOTLINE

 

• 

From 15° to 23 °C : 6 to 8 hours per day.

• 

Above 23 °C : 10 to 12 hours per day.

The higher the bather load and the pool water temperature, the longer the filtration cycle should be. 

To optimise filtration efficiency, run the filter during the day (between 8:00 am and 9:00 pm) and, more 

generally, while the pool is in use (one bather pollutes 3 m³ of water ).

19.3 

Cleaning the pre-filter & filter backwash

After a certain time, a drop in the flow rate at the return fittings will be noted. This is due to progressive 

clogging of the filter or pump prefilter.

19.3.1 

Pre-filter

If the pressure indicated on the pressure gauge falls below the nominal pressure indicated by the blue 

needle, clean the pump pre-filter:

• 

Stop the pump.

• 

Turn the 6-way valve to CLOSED.

• 

Close the suction and return valves.

• 

Open the pump pre-filter. 

• 

Remove the basket.

• 

Use a water jet to remove any impurities.

• 

Put the pre-filter basket back.

• 

Put the pre-filter lid back on making sure that the seal is correctly positioned and that there is enough 

water to prime the pump. 

• 

Move the 6-way valve to FILTRATION.

• 

Open the suction and return valves.

• 

Switch the pump on.

• 

Vent the filter (this should be done each time the pre-filter is cleaned and at least once a week).

19.3.2  Filter

If the pressure indicated by the pressure gauge rise above the nominal pressure, carry out a filter back 

wash.

• 

Stop the pump.

• 

Check the pre-filter and clean it out if necessary (as indicated above).

• 

Before proceeding with a filter back wash or draining the pool, make sure that the waste pipe (not 

provided) has been attached to the waste outlet. 

• 

Put the 6-way valve to BACK WASH.

• 

Turn the pump on.

• 

Observe the colour of the water in the turbidity sight glass.

CAUTION a few seconds will elapse before cleaning begins (water becomes cloudy).

• 

As soon as the water runs clear, stop the pump.

• 

Put the 6-way valve to RINSE.

• 

Switch the pump on for 20 to 30 seconds, to remove impurities and settle the sand.

• 

Stop the pump.

• 

Turn the 6-way valve to FILTRATION

• 

Switch the pump on.

After a backwash, the pressure in the filter should drop back down to the nominal pressure.
