4.2 Filling the filter casing with quartz sand
NOTICE
Use the correct grain size: A grain size that is too large
reduces the filtering quality, whilst a grain size that is too
small results in the sand also being flushed into the pool.
Ideal grain size: 0.4 mm to 0.8 mm.
The filter casing (2) should be filled with approx. 4 cm of sand.
Place the riser pipe (4) on the centre of the casing base with a
rotating movement so that the filling and centring aid can be
placed onto it without problems. Now the filter vessel (2) is filled
with filter sand (according to table 5.2.1).
NOTICE
Absolutely no sand may fall into the pipe (4)!
Now the 6-way-valve (10) can be placed on the riser pipe (4).
However, first remove the filling and centring aid. Assemble the
valve (10) including o-ring (9) with the two support half rings (13),
screws (14) and nuts (15) centrally on the filter container (2). If
necessary, align carefully with a rubber hammer. If required, use a
pipe wrench to tighten the support ring (13). Finally check the
centred seating once more.
