MULTIPORT VALVE FUNCTIONS

CAUTION:
The valve handle position is changed simply by rotating it; do not press down.
FILTRATION:
Usual valve
position. Water from the pump
crosses the fitler 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 this position.
CIRCULATION:
Water from
the pump returns directly to the
pool without passing through
the filter..
CAUTION:
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 its guarantee.

RECOMMENDATIONS

IMPORTANT
Upon putting the filter into operation for the first time observe the direction of water flow attentively: in
"Filtration" position, 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.
FILTRATION
DRAIN:
Water from the pump
passes directly to waste without
passing through the filter.
BACKWASH: Water from the
pump 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.
