5. USER MANUAL

EFFECTUATE ALWAYS THE CHANGIING OF THE SELECTOR VALVE POSITION WITH THE

PUMP STOPPED.

5.1.-FILTER

With the pump stopped you have to put the selector valve handle in the position

of "FILTER".

Start up the pump.

During the action is convenient to observe periodically the manometer due to the

fact it indicates as the saturation grade of the filer.

5.2. BACKWAH

The solid particles that contain the pool and are picked by the catch basin and

the skimmers remain holding down in the sand of the filter and in consequence

the pass of water is constantly bringing down. For this reason the pressure is

progressively increased. When the pressure arrives to 1,3 kg/ cm², it will realise

a "BACKWAH".

You should proceed in the following way:

Put the selector valve in position "BACKWAH" and it starts the pump. Effectuate

this manoeuvre during 2 minutes. Observe the selector valve visor to check if

this time is correct, it depends on the dirty accumulated in the filter.

ATTENTION

5.3. RINSE

After realising the "RIINSE" of the filter and before putting the system in

filtration, it is convenient realise a "RINSE", so as to avoid that the first quantity

of water, still silty goes directly to the pool. For this with the pump stopped, put

the selector valve in position of "RINSE". Start up the bomb to realise this

operation approximately during a minute. Observe the selector valve visor to

check if this time is correct, it depends on the dirty accumulated in the filter.

5.4. RECIRCULATE

When we put the selector valve in this position, the water enter from the pump

go directly to the pool, without going through the interior of the filter.

5.5. WASTE

In the case that the pool doesn't have a catchment in the bottom of it, you can

scoop it through the pump of the filter. It has to be put in the position of

"WASTE". To realise this operation, open the valves of the catch basin and close

the valves of the Skimmers and Pool Cleaners.

5.6. CLOSED

This position closes the entrance of water to the filter.
