FLOWMETER
To control the suction flow of the pump. It is placed at the end of the length of hose of the swimming pool.
AUTOMATIC FLOW CONTROL
This control automatically adjusts the suction flow to absorb minor variations.
Using the conical adaptor, connect the regulator to the suction inlet (pool cleaner or skimmer
inlet) and then fix the hoses. Finally, connect the automatic regulator of the flow to the male
terminal of the hose.
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 VALS
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 the hose 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 the drain.
4. Connect the VALS to the hose. (we always recommend checking the suction flow setting)
If the Vals Pool Cleaner is not operating correctly follow the next point (5. Operation – Adjusting the suction flow)
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 VALS.
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 Level:
•
Increase the flow by turning the regulator clockwise until the indicator on the gauge enters the optimum
area.
•
In the event of not reaching the optimum operating area, adjust the suction valve on the skimmers until you
achieve optimum operation.
•
Remove the gauge and connect the automatic pool cleaner to the hose.
Optimum Level: The flow is perfect for operating the cleaner. Remove the
gauge.
Maximum Level:
•
Reduce the flow by turning the regulator anticlockwise until the indicator on the gauge enters the
optimum area.
•
Remove the gauge and connect the automatic pool cleaner to the hose.
