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 EFFICACY.
Whenever chemical products are used to treat the pool water, it is recommended that the minimum filtra-
tion 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 neew 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).
