Sandfiltersystem Basic 3

Using for the first time

The filtering system is ready for use when the filter tank has been filled in accordance with the
instructions, and the hoses also have been correctly attached.
Note: First, a so-called "backwash" is performed, to avoid grit and grime leaking into the pool when
the filtering starts for the first time (see section 6 – The backwash procedure).
Ensure that the pump is placed below the water line and that the water flows to the pump from the
pool via the suction hose. Switch on the pump and wait until it starts to draw in water in a normal
way. Where necessary, this can be repeated several times.
NOTE: The filter sand should be manufactured according to the standard DIN 12094. Filter sand
that is manufactured according to this standard has no more than 10 per cent grit below the
specified grain size. Small pieces of grit are prone to whirling into the pool and resting on its bottom
until they are completely rinsed away by the filter tank.
