Replacing The Cable; Maintenance - GRE AR-135 Installation And Maintenance Manual

Remove the upper floating ring of the skimmer. Then, without removing the pre-filter basket, place the suction cover
accessory on the upper part of the skimmer with the inlet facing upwards and submerge the skimmer inside the pool to a
point which ensures that the suction cover does not draw in air.
Prime the hose.
Make sure that no air enters the hose and connect it to the suction cover inlet. The connection of the hose and the cover
should always remain submerged in order to prevent air from entering.
Start up the pump and proceed to clean the bottom of the pool.
5.6 Rinsing
After "WASHING" the filter and placing the installation in the "FILTERING" position, the water flowing to the pool will be
cloudy for a few seconds. To avoid this cloudy water from circulating in the swimming pool, the "RINSING" operation
should be performed as follows. Immediately after "WASHING", stop the pump, place the selector valve in the "RINSING"
position and connect the pump for 1 minute. After this time, stop the pump and place the valve in the "FILTERING"
position.
5.7 Closed setting
The CLOSED setting of the selector valve is used to prevent water from circulating through the hoses and the filter.
5.8 Recirculation
In this position the selector valve allows the water from the pump to go directly to the swimming pool without passing
through the inside of the filter.

6 REPLACING THE CABLE

If the cable is damaged, proceed as follows:
? Disconnect the unit from the power outlet.
? Loosen the screws which secure the connection box cover and lift the cover (Fig. 11/17).
? Disconnect the connection box terminals from the pump. Take note of its position.
? Remove the cable so that it can be replaced and then proceed in the opposite order of that described.

7 MAINTENANCE

After the bathing season has ended, the filter should be kept in a dry place where it is protected from bad weather
conditions. For this purpose, after performing a final backwash to clean the silica sand, dismantle the hoses and drain the
water in the filter through the tank drain plug until it is completely empty.
After removing all 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: After a long period of inactivity, before operating the filter, check that the motor shaft is not jammed.
After winding the motor, move it with a flat screwdriver at the end visible through the ventilation cover until it is released
and then turn the shaft from right to left. After an extended period of stoppage, it is also advisable to ensure that the filter
is primed before starting it up.
7.1 Pump care
The filter pump is designed to operate without any specific maintenance. However, 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 suction hose and discharge hose from the pump.
? Loosen the screws which secure the cover to the pump body.
? Clean the wheel. If you see that it is broken, ask the pool manufacturer for a replacement.
? Reinsert the pump cover. Ensure that the coupling is fully centred and firmly tightened.
? Reassemble the suction hose and the discharge hose on the pump.
? Remove the sealing plug from the skimmer.
