For pure and crystal clear pool water, use Filter Balls:
•
Superior filtering effect compared to normal filter sand.
•
Catch floating particles in the water right down to 10 micrometres (filter sand down to 40-50 micro-
metres).
•
Use 700 g of filter Balls to replace 25 kg of filter sand.
•
No maintenance or extra flocculants required.
•
No more filter sand in your pool.
In case you use filter sand we recommend that you run the BACKWASH 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 pressed
through filter material. The sand filter system manometer shows the pressure inside the tank. If the
pressure rises with approx. 0.2 -0.3 bar above the first gauges level (approx. 0.4 bar), when the
filter and sand was completely new and pure, it is time for a backwash.

User instructions for the 7-way valve
The filter system has a 7-way handle on top of the tank, wherefrom you can manually manage the
cleaning process.
With every switching of the 7-way valve the filter pump must be turned off!
Press the handle down and rotate it to the desired position. Following positions are available:
•
FILTER: The dirty water comes from the pool and gets pressed down through the filter tank and
gets filtered and pumped back into the pool.
•
BACKWASH: The water comes from the pool and gets pushed op through the filter tank and
pumped away to a drain.
•
RECIRCULATE: The water runs from the pool and returns again without getting filtered.
•
RINSE: The water comes from the pool and the top valve is cleaned from sand grains. This should
be done after a backwash procedure.
•
WASTE: The water comes from the pool and is pumped directly out of the pool without filtration.
Water can be lead to a drain.
•
CLOSED: All positions are closed. The water cannot circulate. This position is used when the filter
is connected to the pool, but not in use.
•
OPEN/WINTER: This position is used during winter. Be sure that the sand filter and pump is 100%
emptied from water and demounted the pool. Place the system frost free during winter. (This posi-
tion also relieves the gasket and sealing in the valve).
NOTE:
NEVER use the valve lever as a handle to carry or lift the filter. It is not made for that
use. The handle will simply break off.
