5.6 Closed setting
The closed setting for the selector valve (fig. 12) is used to prevent water from circulating through the hoses and the filter.
6 REPLACING THE CABLE
If the cable is damaged, proceed as follows:
? Disconnect the unit from the power point.
? Place the selector valve on the closed setting. Use the plug to close the skimmer, so that only the water in the hose is
drained.
? Disconnect the hose which joins the pump and the filter. Loosen the clamp and remove the protective cover (Fig. 9).
? Loosen the two screws which secure the filter housing and lift the housing (Fig. 10).
? Loosen the two screws which secure the cable (Fig. 11).
? Disconnect the three terminals in the pump connection box. Take note of their position.
? Remove the cable so that it can be replaced. Then, perform the same steps in the opposite order from that described
above.
7 MAINTENANCE
After the bathing season has ended, the filter should be kept in a dry place where it is protected from inclement weather.
For this purpose, after performing a final backwash to clean the silica sand, dismount the hoses and drain the water in the
filter through the tank drain plug until it is completely empty.
After removing all of the water from the filter, carefully clean the remains of silica sand from the thread before
replacing the plug. Failure to do so could damage the thread.
The filter tank drain plug should only be used in this operation.
VERY IMPORTANT: Following an extended period of inactivity, before starting up the filter check that the drive
shaft is not jammed. Remove the protective housing as shown in section 6. After winding the motor, use a flat
screwdriver to move it by the end which is visible through the metal ventilation cover, until it is released and the
shaft turns to the right and the left. If it does not turn, clean the wheel of the turbine as shown in section 7.1.
After stoppage f or an extended period, it is also recommendable to make sure that the filter is primed before
starting up.
7.1 Care of the pump
The filter pump is designed to operate without any specific maintenance. Nevertheless, if the unit is used in pools which
are extremely dirty, especially with leaves, this may cause the pump shaft to jam. In this case, proceed as follows:
? Disconnect the unit from the power point.
? Place the valve on the closed setting.
? Insert the sealing plug on the skimmer.
? Disconnect the pump suction hose located next to the white housing.
? Release the pump-head connection sleeve, starting at the end which projects out beyond the housing.
? Disassemble the filter housing, following the same procedure as in replacement of the cable.
? Loosen the 9 (nine) screws which secure the cover of the pump body.
? Clean the wheel. If you see that it is broken, ask the pool manufacturer about replacement.
? Reinsert the pump cover. Ensure that the coupling is fully centred and firmly tightened.
? Connect the sleeve to the pump cover.
? Reassemble the housing, following the same steps as described for disassembly in the opposite order.
? Reassemble the pump suction hose next to the white housing.
? Remove the sealing plug from the skimmer.
