4. Starting up & counterwash (backwash) procedure
The pool must be full of water up to the mid height of the skimmer. The water must circulate to the pump. (Be
sure that the tank is placed under the water surface, so the water can flow naturally in the hose towards the
pump.)
Now purge the air from the filter system. If some exists, open slightly the top of the pre-filter of the pump until the
water enters the pre-filter.
Warning! The filter system must not be used without water.
The water ensures the cooling of the pump. If you use the filter system without water, the warranty will not apply.
Place the valve selector in position COUNTERWASH. Only this way can the pump be started. Begin a cycle of
COUNTERWASH of 2 to 3 minutes. Then switch off the pump and put it in CLEAR position.
Important! Before changing the position of the selector valve, stop the pump.
The CLEAR cycle lasts +/- 30 seconds. Switch off the pump again and put the selector valve in FILTRATION
position. Evacuate the water from COUNTERWASH & CLEAR to the hosepipe or onto the lawn.
We recommend doing 2 filtration cycles of 4 to 5 hours a day.
It is also in FILTRATION position that the pool floor is vacuumed. After the vacuuming of the pool floor or when
the pressure increases (2 or 3 levels) on the gauge, it is necessary to do a CLEAR cycle.
After a COUNTERWASH, it is imperative to do a CLEAR cycle for about 30 seconds. This permits the sand to
be deposited in the filter.
The EMPTY mode also permits vacuuming the pool floor and leading impurities (e.g., algae) directly to a water
drain instead of returning it to the filter material. During this cycle, the water from the bottom of the pool is
vacuumed to the exterior. Afterwards water must be added to restore the water level in the pool.
Note when using filter sand
We recommend that you run the COUNTERWASH procedure minimum once a week.
The filtering process leads to a continuous capture of impurities in the filter sand. This ongoing process will lead
also to an increased pressure inside the tank, when the water is pressed through the filter material. The filter
system manometer shows the pressure inside the tank. If the pressure rises with approx. 0.2 -0.3 bar above the
first gauge's level (approx. 0.4 bar) when the filter and sand was completely new and pure, it is time for a
backwash.
