Summer Fun SF-130 Manual De Instalación Y Mantenimiento página 9

To change the valve setting, proceed as follows for models SF135, SF140, SF150
Always disconnect the power socket.
Press firmly on the upper valve control until the front rib is released from its housing and it can turn on
its own axis.
Gently turn the control until the front rib is aligned with the housing for the desired operation.
Release the control gradually and check that the front rib is fully inserted in the appropriate housing.
5 OPERATION
The operation of this filter is based on the filtration capacity of the silica sand which 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 which retains the impurities in the water. The environment, trees, pollen, insects and frequency of
bathing, as well as other factors, determine the dirtiness of the water in the pool. Depending on the dirti-
ness, the silica sand in the filter should be cleaned with greater or less frequency.
To maintain the pool water in good condition, use the chemical products recommended by the manufactu-
rer (chlorine, alga protection, flocculant etc.).,
THE CHEMICAL PRODUCT SHOULD NEVER BE PLACED IN THE BASKET OR THROUGH THE FILTER, THIS
WOULD DETERIORATE THE MATERIALS OF THE UNIT AND LIMIT ITS EFFICACY.
5.1 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 which causes defective circulation of water. This fact prevents proper filtration of the
water by the silica sand and is detrimental to the motor.
The filter may become unprimed for several reasons:
Starting up a new unit.
Starting up a unit after an extended period of inactivity.
Following use of a suction bottom cleaner.
Air absorbed by the skimmer due to the low level of water in the pool.
Due to incorrect use of the unit, suction cover or skimmer plug.
5.2 FILTRATION
Before the first filtration operation, perform a backwash of the sand. (Section 5.3)
The valve must be on the filtration setting. The service life of the filter will be longer if the periods of con-
tinuous operation do not exceed 4 hours. The need for daily filtration is determined by the volume of
water in the pool in m in comparison to the m

and placed at 3.5 m. from the pool. Leave the motor at off for at least 2 h. between each 4 h period of
operation.

In the initial filtration treatment it is important to leave the filter off for the time indicated. It is recommen-
ded to increase the filtration time the higher the water temperature of the pool.
5.3 SAND FILTER BACKWASH
The backwash process cleans the silica sand from inside the filter. This process should be done regularly.
For this purpose you should observe several factors which indicate the dirtiness of the sand:
Decrease in the flow rate of feedback is detected, after checking that the pump is well primed.
Pressure gauge indicates that there is excess pressure (needle pointing between yellow and red, or on red).
