the sand or filer is cleaned.
1. Stop the filtering.
2. Put the multi-directional flap to the WASH position.
3. Start the filter and let it work for at least 2 to 3 minutes.
4. Stop the filtering again, put the multi-directional flap into RINSE position and re-start the filter for 10 seconds.
5. Stop the filer and put the multi-directional flap into FILTERING position.
6. Re-start the filter and check that the pressure is correct.

WATER TREATMENT
Whichever is your filtering system, you will need to chemically treat the pool water to destroy the bacteria and the micro-bodies and to avoid
development of algae.

First, you have to verify the pH level using an analysis kit. Pay attention that the test bottles are only valid for one year.

During the first use, you should wash the filter (check the filer system maintenance). Filtering is a mechanical treatment that allows cleaning the pool water by
means of eliminating the impurities and contaminating particles. The hydraulic circuit and water purifying group is an essential element for the optimal operation

OPERATION PRINCIPLE:
The skimmer sucks the water from your pool (this element and especially the

another basket filters medium impurities, therefore its cleanliness is essential for good
operation).
The pump sends the water towards a filter that retains all the suspended impurities thanks to its filtering material. This is a sand filter. The filtered water returns
to the pool. This unit can be manipulated, programmed and protected using an electrical unit (optional).
The water from your pool should be subject to physical and chemical treatment to keep its transparency and to guarantee a completely safe bath.

YOU SHOULD ALWAYS MAKE SURE THAT:
1. The water level is correct: that is to say, slightly above half of the skimmer.
2. The skimmer and pump pre-filer baskets are clean.
3. The hydraulic circuit is controlled and the flap positions verified.
4. The filter can be started and the pressure controlled with a pressure gauge (according to the type and the position of the technical location
regarding the pool).
HAVING ACCESS TO THE POOL IS PROHIBITED IN THE CASE THAT THE FILTER SYSTEM IS DETERIORATED
