Replacing The Cable - GRE AR720 Manual De Instalación Y Mantenimiento

• Disconnect the suction hose from the skimmer inlet by the outer part of the pool wall. Loosen the clamp that secures
the hose carefully so that the liner is not damaged. Hold the hose so that it does not leak and submerge it immediately
in the pool so that it remains primed.
• Weigh down the end of the suction hose with a heavy object that cannot damage the liner so that it is forced to sink to
the bottom of the pool.
• Start up the pump and drain the pool. Remember that the filter will not fully drain the pool. When the pump no longer
sucks in water, shut if off.
• Once the pump to drain the pool is on, do not stop the process until it is finished, to ensure that does not become
unprimed.
• If you are going to refill the pool with water, first remove the remaining water through the drain without damaging
the pool.
THE HOSE SHOULD NOT CONTINUE SUCTIONING THE BOTTOM OF THE POOL LINER. THE PUMP MAY BE
SERIOUSLY DAMAGED IF IT OPERATES WITHOUT WATER CIRCULATION. THE LINER MAY ALSO BE
Cleaning the bottom of the pool
In order to clean the bottom of the pool, use the pump filter with one of the following accessories:
"Riñón" bottom cleaner, "Oval" bottom cleaner (you will also need a ø38 mm hose and the pole). To purchase these
items, consult your establishment or ask the After-Sales Service provided by the pool manufacturer. Always use original
replacement parts.
A hose which extends beyond the length required to reach all points of the pool is more difficult to use. Cut off the section
of the hose which is not needed. Check that the rubber terminals conserve their seal.
Priming the bottom cleaner hose:
Insert the bottom cleaner into the pool vertically, with the pole and the hose connected. Let it fill with water and keep the
rest of the hose outside of the water. Continue to insert the hose in the water slowly by 50 cm sections which should be
submerged at the same time as they are completely filled with water. Proceed up until the end, when the entire hose is
filled with water and submerged. If the hose is not fully primed, the bottom cleaner will not perform suction and the
cleansing unit may be damaged if it is forced to operate when it is empty.
Rinsing in models AR720 and AR725
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"
(Fig.7), position and connect the pump for 1 minute. After this time, stop the pump and place the valve in the
"FILTERING" position.
Recirculation in models AR720 and AR725
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 (Fig.7).
Closed
The CLOSED setting of the selector valve is used to prevent water from circulating through the hoses and the filter
(Fig.7).

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.
• 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 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. 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 for an extended period, it is also recommendable to make sure that the filter is primed before starting up.
DAMAGED BECAUSE OF SUCTION.
