3 way valve:
The filtering system is an economic basic model that is equipped with a 3-way valve on the filter tank’s lid, so
that the cleaning can be controlled manually. Press the handle down with the palm of your and turn it to the
desired position. The following working positions are possible.
1.
Filtering- Water from the pool is pressed through the filter tank and pumped back to the pool.
2.
Backwash- Water from the pool is pressed through the filter tank and is pumped back to an
external outflow. Cleansing of collected impurities in the filter sand.
3.
Closed- All valve outlets are closed and water cannot circulate.
NOTE
: the 3-way handle on the filter tank valve must never be used in an attempt to lift the filter tank! The
handle is not constructed for this purpose and such an attempt may cause the handle to break.
Maintenance:
Interval
Action
Weekly
Clean the per-filter basket. Carry out the backwash regardless of how dirty the
filter is.
Annual
Get the filter system ready for winter before there are frosts. Replace the filter
sand in early spring before the sand filter is put into use again.
NOTE:
This filter system should not be used without a permanently installed skimmer in the pool.
Alternatively, a small leaf filter or floating surface-skimmer is used in the pool, assuming the pool is plastic with
solid sides. The skimmer captures leaves, twigs, and branches etc. that would otherwise collect in the pump
and totally block it. The pump is easily destroyed by such and the guarantee does not cover such damage.
