3. TOP SELECTOR VALVE
VALVE TYPES AND FUNCTIONING
A 5-way valve: The selector valve on top of the filter is used to select the 5 different filter modes: filtration, backwashing,
rining, draining and closed.
B 6-way valve: This valve has the same mode as the 5-way valve plus a recirculation mode.
To vary the position of the valve, proceed as follows:
•
Disconnect the unit from the mains.
•
Firmly press the lever on top of the valve whilst loosening the front rib until it can be turned.
•
Gently turn the lever until the front rib is aligned with the desired setting.
•
Slowly release the lever ensuring that the front rib fits in place.
4. OPERATION
The operation of this filter is based on the filtration capacity of the silica sand that is inside. The water in the pool is driven by
the filter pump and forced to pass through the silica sand. The sand acts as a filtering element that retains the impurities in the
water. The environment, trees, pollen, insects and frequency of bathing, amongst other factors, determine the dirtiness of the
water in the pool. Depending on these factors, the silica sand in the filter should be cleaned with greater or less frequency (see
section 5.3). Check the level of dirt in the filter regularly.
To keep the pool water in good condition, use the chemical products recommended by the manufacturer (chlorine, algaecides,
flocculants, etc.).
CHEMICAL PRODUCTS SHOULD NEVER BE PLACED IN THE SKIMMER BASKET OR FED THROUGH THE FILTER, AS THIS
WOULD DETERIORATE THE MATERIALS OF THE UNIT AND LIMIT ITS EFFICIENCY.
Whenever chemical products are used to treat the pool water, it is recommended that the minimum filtration time is respected
in order to protect bathers ‘health, as stated by the health regulations.
4.1. PRIMING THE FILTER
The filter must be correctly primed at all times. If the filter is not primed, this means that an air chamber has been created inside
that causes defective circulation of water. This prevents proper filtration of the water by the silica sand and is detrimental to the
motor.
The filter may become unprimed for several reasons:
•
If a new unit is connected.
•
If a unit is started up after an extended period of inactivity.
•
Following the use of a suction pool cleaner.
•
If air has been absorbed by the skimmer due to a low level of water in the pool.
•
Due to incorrect use of the unit, suction cover or skimmer plug.
When is the filter unprimed?
We can see that the filter is unprimed when:
•
The water entering the filter sounds like it is falling freely. This indicates that an air chamber has been created between the
water inlet and the silica sand.
•
An excess of air bubbles is released through the return nozzle.
•
A pool cleaner (not supplied) does not operate with a suction system, and the silica sand remains clean after cleaning.
•
How can the filter be primed?
•
Verify that the suction hose is connected to the skimmer and the passage is clear (the plug is not in place).
•
With the valve in the filter position, slightly loosen the drain nut that is beside the pressure gauge, so as to expel the air
accumulated inside the filter.
•
When you see that only water is released (for 1 to 2 minutes), re-tighten the nut.
