plate and put on the filter container.
• Place it on a hard and flat surface, no further than two metres from the connection
• Connect the filter tube with strainer (if not connected) and insert the tube into the filter
container. Place the funnel on its top edge. This not only centres the filter tube but it also
prevents the pouring of sand into the tube.
• Pour the weighed quantity of sand into the container. The proper weight can be found in the
“Technical specification” table. (If you cannot weigh, a reasonable amount is about half of the
volume but no more than three quarters). When filling, be careful to avoid getting sand into
the filter tube.
• Slide the seal on the perimeter of 4-way valve (if not already done).
• Clean the edge of the filter from sand residues
• Put the valve on the filter tube and close the filter pan. Connect with the sleeve (2) and tighten.
Do not use excessive force to avoid rupture of the sleeve.
• Connect the flexible hose (gooseneck) to the pump and secure it with a hose clamp
• Connect the other end to the inlet valve of the 4-way valve of the filter container. Described
as PUMP
• Connect water inlet directly to the pump.
• Connect the filtered water outlet to the 4-way valve. Described as
POOL .
• Connect the wastewater outlet to the 4-way valve. Described as WASTE
• Modes of operation - the position of the lever of the 4-way valve
• BACKWASH - clean sand and dirt
• RINSE - rinse the filter after cleaning and spillage
• FILTRATION
• WINTER
WARNING : Never change modes when the pump is turned on! Before moving the valve
lever, always wait for 30 seconds after turning the pump off for the impurities to settle.
COMMISSIONING
.
• After filling the filtration with sand and assembling, it is first necessary to pump, irrigate and
bleed the filtration.
WARNING: Never run the pump without water!
• Place filtration lower than the level of the tank to be filtered and open the suction and return
valves which causes flooding. Set the valve lever to BACKWASH until water starts to leak from
the valve. Before the first commissioning, it is first necessary to get rid of the fine, inner dirt
and stuck sand. Therefore, when the lever is in the BACKWASH position, start the pump and
rinse the filtration. After rinsing (approximately 2 minutes) turn off the pump and wait about 30
seconds to allow swirling silt and sand to settle down, move the lever into the RINSE position.
Turn on the pump and wait until the water from the WASTE outlet is clean. Then turn the pump
off. The filtration is ready for operation. Check the connections of all hoses.
OPERATION
:
• Before commissioning, all the water valves in the circuit must be open.
• Switch the lever into FILTRATION position and turn the pump on.
• Record the initial pressure of the gauge. It is not determined because it varies according to
specific conditions. (Tank size, hose length, location, etc.). Knowing the value of the initial
