WATER TREATMENT

12.1

Water filtration

12.1.1 Operating the filter multi-port valve
To change the valve handle position, simply rotate it; do not press down on it before turning it.
Always stop the pump before changing the valve position. Failure to comply with this instruction could
entail serious damage to the filter and cancellation of the guarantee.
As a safety measure, in the case of an above-ground installation configuration, we recommend that
the filtration system is stopped while the POOL'N BOX is in use.
FILTRATION: Usual valve
position. Water from the pump
crosses the filter from top
to bottom and returns to the
pool.;
CLOSED: No water
circulation is possible. The
pump should never be
allowed to run when the
valve is in thisposition.
CIRCULATION: Water from
the pump returns directly
to the pool without passing
through the filter.
12.1.2 Start up the filter
Before putting the filter into operation, carry out a backwash to clean the filter medium and remove excess
sand along with any dirt or debris. (The filter backwash procedure is set out in the following paragraph).
Before starting the pump, make sure that the pre-filter is filled (the pump should never be allowed to run
dry). When the filter is first started for the first time observe the direction of water flow attentively: in the
"Filtration" position, the water should flow from the top of the filter to the bottom. In the event that the pipes
were inverted during assembly or that the multiport valve is faulty, water will travel from the bottom to the
top leading swiftly and inevitably to damage to the collector plate and the walls of the tank. The following
signs are strongly suggestive of incorrect assembly:
• low pressure reading at the pressure gauge.
• a rapid drop in the flow rate even after backwashing the filter and ensuring that the pump prefilter is
clean.
• continuously cloudy pool water.

DRAIN: Water from the pump
passes directly to waste
without passing through the
filter.
BACKWASH: Water from
the pum crosses the filter
from the bottom to the top
and is then routed to waste
taking with it dirt and debris
trapped by the filter.
RINSE: Water from the
pump crosses the filter
from top to bottom and is
routed to waste.
