Place the valve selector in position COUNTERWASH. Only this way can the pump be started. Be-
gin a cycle of COUNTERWASH of 2 to 3 minutes. Then switch off the pump and put it in CLEAR
position.
Important note!
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. algea) direct-
ly 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 resore 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
are pressed through the filter material. The filter system manometer shows the pres-
sure inside the tank. If the pressure rises with approx. 0.2 -0.3 bar above the first gaug-
es level (approx. 0.4 bar) when the filter and sand was completely new and pure, it is
time for a counterwash.

Cleaning the bottom of the pool
The vacuuming of the pool floor is carried out in FILTRATION position of the valve.
Switch the pump off. Use a hose clamp to connect a pool hose to the round suction plate of the
pool skimmer (See fig. 10). Alternatively place a pool hose into the bottom of the skimmer. This will
demand a sucking hose with a special muff connector. Make sure to remove all air from the hose
before cleaning.
The air will come out by filling the hose with water when holding it in front of the inlet to the
pool while the pump is running.
