Flow Control - Astralpool BOLERO.ND Manuel D'installation Et D'entretien

Place the counterweight in the hose at about 2 metres from the BOLERO.ND. If the cleaner tends to rise at the front, place the counterweight
further away from the cleaner. If it rises at the back, place the counterweight of the hose nearer to the cleaner.
A second counterweight should be used if the pool is more than 2.2 m. deep.
FLOW METRE
Its measures the suction flow of the pump. It is placed at the end of the length of hose of the swimming pool.

FLOW CONTROL

This control adjusts the suction flow to absorb minor variations.
Fasten the male terminal of the hose in the automatic flow control and then connect the control
to the suction socket (skimmer or pool cleaner socket) using the conical adapter.
If it is installed in the skimmer, first remove the basket and connect the adapter in the suction
socket.
Ensure that the arrow on the lower part is pointing in the direction of suction. The control
enables you to adjust the flow to the optimum level depending on the power of the pump. Turn
the control clockwise to increase the flow through the pool cleaner.
Note that it should always be submerged in water, otherwise air will enter and it will not be able
to adjust the flow properly.
4. START-UP
PREPARING THE SWIMMING POOL AND FILTERING EQUIPMENT
The filtering equipment should be working at maximum flow before installing the cleaner, and therefore you must check that the skimmer, filter
and pre-filter of the pool pump are clean before connecting the cleaner, otherwise you will have to adjust the cleaner again after cleaning the
filtering system.
You just have to carry out these simple preliminary steps:
1. Clean the pre-filter of the pump and the skimmer.
2. Backwash and rinse the filter until the transparent turbidity control sight glass is clear.
3. Close the drain of the pool.
4. Always direct the return nozzles towards the bottom of the pool, so that they do not cause waves on the water surface. The water current on the
surface would push the hose and stop the cleaner from covering the whole of the pool. Also, by directing the return current to the bottom of the
pool, the water will circulate better.
CONNECTING THE BOLERO.ND
The hose can be connected to one of the skimmers of the pool or to the pool cleaner inlet. We recommend you connect it to the pool cleaner
inlet to operate more efficiently.
1. Install the automatic flow control in one of the skimmers or in the suction nozzle using the
conical adapter. IT IS RECOMMENDED TO INSTALL IT IN THE SUCTION NOZZLE. In
swimming pools with two skimmers, priority will be given to the skimmer located in the deep
end of the pool.
2. Fill the hose with water and keep it underwater. Check that the hose of the cleaner does not
contain air and then connect it to the control. The counterweight and deflector should already
be installed in the hose.
3. Close all other suctions routes: skimmers, the pool cleaner inlet, the drain, unless the pump is very powerful (use the flow control valve).
4. Connect the BOLERO.ND to the hose.
5. OPERATION
ADJUSTING THE SUCTION FLOW
The flowmeter enables you to check that the installation has the sufficient flow required for
the good working order of the BOLERO.ND.
We recommend you to always control the flow, particularly if you are not sure as to the
suction power of the pump of the pool.
All these operations should be carried out under water so that the pump does not suction in
air.
1. Separate the pool cleaner from the hose and replace it for the flow metre.
2. Observe the area indicated by the metre:
Minimum:
Increase the flow by turning the control clockwise until the indicator is in the correct area.
•
Remove the metre and connect the apparatus to the hose.
•
Ideal : The flow is ideal to operate the cleaner. Remove the metre
and connect the apparatus to the hose.
