• Once the filter is filled with sand it is
necessary to carry out a wash cycle.
Proceed as described in the paragraph 4.2.
3. SELECTOR VALVE
The selector valve has a handle of 6 positions
that selects any of the necessary operations
to obtain the maximum efficiency from the
filter: filter, backwash, recirculation, waste,
rinse and closed. These 6 positions are
identified on the label on the top of the valve.
Manometer assembly
For the assembly of the manometer is not
necessary the use of tools or Teflon tape; use
the o-rings and fix it by tightening it with your
hands (see figure no. 2).
Change of valve handle function (see figure
no. 5)
IMPORTANT: The pump should be
switched off when the position of the
selector valve handle is being changed
• Press softly the valve handle until freeing
the rib from its housing (1º)
• Proceed to turn the handle to its desired
position until the rib fits in the housing in
front of the function (2º)
• Release the handle softly, checking that
the rib is perfectly coupled in the housing
4. FILTRATION
This filter is based on the silica sand inside
the tank, capable of retaining any dirt
coming from the pool. The water is drawn
in from the bottom of the pool and is carried
through the pump to the filter. The silica
sand load through which the water circulates
in a descending motion, retains the debris
suspended in the pool and send clear water
back to the pool.
Trees, insect, bath frequency, weather
conditions determine the dirt degree of the
water, as well as the frequency of cleaning
the sand filter (see paragraph 4.2.).
Filtration is only one part of maintaining
clean swimming pool water, and it is
inseparable from the chemical treatment;
one without the other will not achieve the
desired result.
NEVER PLACE THE CHEMICAL
PRODUCT IN THE BASKET OR
THROUGH THE FILTER. IT COULD
DAMAGE THE COMPONENTS OF
THIS DEVICE AND REDUCE ITS
EFFICIENCY.
Priming of the filter
The filter should be at all times correctly
primed. Not being properly primed means
that an air chamber has appeared inside
the filter tank, thus preventing the proper
circulation of the water, and, consequently,
the proper functioning if the filter.
How to prime the filter?
• Place the valve handle in the Filter
position. Slightly loosen the drain screw
placed by the manometer. This will allow
the air kept inside the filter body to escape
the tank.
• Once ONLY water is coming out the drain
(between 10 and 20 seconds), tighten again
the drain screw.
NEVER MANIPULATE THE VALVE
WITHOUT SWITCHING OFF THE
PUMP
4.1 Filtration
• Filtration is only one part of maintaining a
clean swimming pool, and it is inseparable
from the chemical treatment; through
the filter the water is physically cleaned,
retaining the debris particles in the water.
In fact the purification process consists
of a perfect combination of the two
treatments; chemical and physical.
• With the pump switched off, move the
selector valve handle to “FILTRATION”.
• Turn on the pump.
• While it is operating, it is best to
periodically observe the pressure gauge,
where the filter saturation degree is
indicated.
Before using the filter for the first time, the
sand should be backwashed (see paragraph
4.2.)
When it is necessary to wash the filter sand?
Each load of sand forms thousands of
channels which pick up all the material
contained and caught up in the filtering
process, the number of free channels
allowing the water to pass is continually
decreasing.
This is why the pressure rises progressively
until it reaches the saturation level At
this pressure, yellow or red area of the
manometer, the filtering sand is unable to
collect any more impurities and must be
cleaned.
If you observe a decrease of the return water
flow, check also the filter pressure.
