SAND FILTER INSTRUCTION MANUAL
Connection of hosepipes to the pump
1.
Skimmer circuit: connecting the skimmer to the connection in front of the pump.
2.
Vacuum hosepipe: joining the upper connection of the pump to the connection designated 'PUMP' on the valve.
3.
Return hosepipe: joining the valve connector of the pool. Secure all the connections with metal clips.
4.
Wastewater hosepipe: joining 'COUNTERWASHER' to the hosepipe or to the lawn. The connection is made with the hosepipe
of the pool and specific metal clips.
Starting up the filter/pump
1.
Before starting up the monobloc, make sure that it is situated outside the pool and at a lower level than the water level in
the pool. The flexible connections must be well connected and fixed.
2.
The pool must be full of water up to the mid height of the skimmer. The water must circulate to the pump.
3.
Now purge the air from the monobloc. If some exists, open slightly the top of the pre-filter of the pump until the water
enters the pre-filter.
4.
Place the valve selector in position COUNTERWASH. Only this can the pump be started. Begin a cycle of COUNTERWASH
of 2 to 3 minutes. Then, switch off the pump and put it in CLEAR position. The CLEAR cycle lasts +/- 30 seconds.
Switch off the pump again and putt he selector valve in FILTRATION position. Evacuate the water from COUNTERWASH
and CLEAR to the hosepipe or onto the lawn. We recommend doing 2 filtration cycles of 4 to 5 hours a day.
In FILTRATION position the pool floor is also vacuumed. After the vacuuming of the pool floor or when the pressure
increases (2 or 3 levels) on the gauge, it is necessary to do a CLEAR cycle.
5.
After a COUNTERWASH, it is imperative to do a CLEAR cycle for about 30 seconds. This permits the sand to be deposited
in the filter.
6.
The EMPTY mode (only possible with the 6-way valve) also permits vacuuming the pool floor and so removes the
impurities (e.g. algae). If not, they would be returned to the filter sand. During this cycle, the water from the bottom of
the pool is vacuumed to the exterior. Afterwards, water must be added to restore the water level in the pool.
