? 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.5.1.1 When is the <strong>filter</strong> unprimed?The <strong>filter</strong> is unprimed when:? The water entering the <strong>filter</strong> sounds like it is falling freely. This fact indicates that an air chamber has been createdbetween the water inlet and the silica sand.? An excess of air bubbles are released through the feedback nozzle.? The bottom cleaner (not supplied) does not operate with suction, and the silica sand remains clean after thecleansing.5.1.2 How can we prime the <strong>filter</strong>?? Verify that the suction hose is connected to the skimmer and the passage is clear (the plug is not in place).? Disconnect the <strong>filter</strong> from the power point.? With the valve on the filtration setting, slightly loosen the drain nut which is next to the pressure gauge so that the airwhich has built up inside the <strong>filter</strong> will be released. If the drain T has not been set in place, loosen the triangular knobuntil water is released through the waste outlet without bubbles.? When you see that only water is released (for 1 to 2 minutes), retighten the nut.? Connect the <strong>filter</strong> to the power point and check that the sound of falling water is no longer heard. Otherwise, repeatthe operation.5.2 FiltrationThe valve must be in the filtration position (FILTER) fig. 12. The service life of the <strong>filter</strong> will be longer if the periods ofcontinuous operation do not exceed 4 hours. The need for daily filtration is determined by the volume of water in yourpool in m 3 in comparison to the m 3 /h <strong>filter</strong> flow rate. Leave the motor at a standstill for at least 2 h. between each 4 hperiod of operation.Example:26 m 33.5 m 3 /hVolume of the pool in m 3Filter flow in m 3=7.42 hours=hours required2 cycles of 4 hours with an intermediarycycle of 2 hours restIn the initial filtration treatment it is important to leave the <strong>filter</strong> at a standstill for the periods indicated.5.3 Sand backwashThe backwash process cleans the silica sand from inside the <strong>filter</strong>. This is achieved by reversing the direction of watercirculation with the top selector valve. This process should be done regularly. For this purpose you should observeseveral 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).5.3.1 For <strong>filter</strong> backwash, proceed as follows:? Disconnect the <strong>filter</strong> from the power point. Never move the selector valve while the motor is running.? Loosen the upper triangular knob on the valve by turning it until the cover is lifted from its housing and turned. Placethe valve on the backwash setting, reinserting the cover in its housing and retightening the knob by turning it. Do notovertighten the knob as the valve may be damaged. Fig. 12.? Connect the Ø38 mm x 1.5 m. hose to the valve waste (fig 8, pos 8) outlet and direct the other end of the hose to adrain or sewer.? Start up the <strong>filter</strong> for approximately 2 min (until no further impurities are released with the water).? Stop the <strong>filter</strong> and leave it at a standstill for 2 min. to allow the silica sand to settle and prevent it from being releasedinto the pool.? Reset the valve to the desired setting (filtration or closed) and remove the hose from the drain outlet.NEVER HANDLE THE VALVE WHILE THE MOTOR IS RUNNING5.4 Draining the poolThe following accessory is provided to empty the pool: portable submersible pump.The <strong>filter</strong> allows you to drain nearly the entire pool after the bathing season has ended. In order to do so, you should setthe top selector valve on the waste setting (fig. 12) without plugging in the <strong>filter</strong> and connect a hose to the free outlet ofthe selector valve in order to channel the water to the drain or sewer. Then, depending on the skimmer model, proceed asfollows:
