2.4 RINSING THE QUARTZ SAND
(BEFORE COMMISSIONING)
Set the hand lever of the 6-way valve to the RINSE
position, switch the filter system on electrically. In
case of very long suction lines, it can take up to 2-3
minutes until the swimming pool water is pumped.
After water starts to be pumped, drain the water into
the sewage system for about 1 minute to prevent an
abrasion of quartz sand from entering the swimming
pool via the inlet nozzle. Then set the valve to
“Rinse” for 30 seconds (see also section 3.2).
Warning! Please operate the 6-way
valve only when the filter pump is
switched off.
Otherwise there is a danger of destroying
the 6-way valve!
2.5 FILTER – OPERATION
Set the hand lever of the 6-way valve to FILTER.
The quartz sand filter for a mechanical water
treatment of your swimming pool is now ready for
operation. Switch the filter system on.
2.6 SETTING THE FILTRATION TIME
The operating time of the quartz sand filter depends
on swimming pool size (water volume), bather load,
weather and the used chemicals.
Example: It is recommended to recirculate the
pool volume 1 to 1.5 times in 24 hours.
If a pool volume of 10 m³ is circulated 1.5 times, a
total of 15 m³ must be circulated. If the pump has
an output of 6 m³ per hour, the operating time of the
filter is approx. 2.5 hours. To achieve an optimal
mechanical cleaning, the filter should be running
without interruption during this time.
Attention: On hot days, the filter time must be
increased to ensure a sufficient disinfection.
(Example: 2 hours in the morning and 2 hours in the
afternoon.) The filter system must also be switched
on on rainy days, as organic impurities get into the
swimming pool via the rainwater, which promotes
algae growth!
2.7 CONNECTING THE SAND FILTER
SYSTEM TO THE POOL
A connecting hose to the skimmer of your pool
(where the dirty water is drawn in) is laid on the suc-
tion side of the pump (horizontal hose connection).
The cleaned water is fed back into the pool via a
connecting hose between the valve of your filter sys
-
tem (the valve has 3 black hose adapters which are
labeled as follows: Return, Waste and Pump) and
the hose adapter labeled ‘Return’.
