Operation; Maintenance - GRE AR-125 Installation And Maintenance Manual

4.1.2. ANCHORING THE BACKPACK SKIMMER BODY
Cut out the liner using a cutter (blade) following marked line (the liner must not be pulled from any point at this time).
Install the double joint of the Skimmer, clamping the plate and the liner (No. 7 Fig. 3).
Place the flap opening in the skimmer (Fig. 5) and pre-install the skimmer in the pool by tightening the 2 short screws (No. 8 Fig. 3) from inside
the pool. These screws should cross through the liner, the double joint and the swimming pool plate and should finally match up with the holes
of the skimmer (Fig. 3).
4.1.3. ANCHORING THE RETURN NOZZLE
From outside the pool, insert the other joint (Fig. 2) in the threaded part of the return nozzle that sticks out.
Screw the return nozzle well into the backpack Skimmer body using the spanner (No. 13 Fig. 2)
4.1.4. ANCHORING THE FRAME OF THE BACKPACK SKIMMER
From inside the pool, place the frame of the backpack Skimmer (No. 9 Fig. 3) on the joint, without the trim cover of the frame. Place the 10
long screws (No. 8 Fig. 3) through the frame crossing through the liner, tighten them just a little to ensure that it fits properly. Do not fully
tighten them at first, start gradually one by one in the order indicated (Fig. 4) until they are fully tightened.
4.1.5. FINAL DETAILS
Place the trim cover (No. 9 fig. 3) taking care to place the level marks in the correct position.
Insert the filtering cartridge with the threaded end facing downwards, and screw into position.
Place the pre-filter basket on the upper part inside the backpack Skimmer, and finally the backpack Skimmer cover, which is placed in position
by turning it.
Finish filling the pool until the water reaches the level between the maximum and minimum marks of the backpack Skimmer opening.
Do not place the suction cover. Only use when the pool floor cleaner is to be used.
4.2. ELECTRICAL CONNECTION
Place the transformer at a minimum distance of 3.5 m. from the edge of the pool (Fig. 1). Connect the transformer to a 230 V and 50Hz
alternate current source with earth connection. It is essential to use an omnipolar switch for the filter to be without voltage while not in use, and
a 30 mA differential switch for discharge protection. (Not supplied. They can be purchased from electrical stores).
Check the operation of the motor by placing your hand in front of the return nozzle to check that water is flowing out.
FILTERING:
The Skimmer is designed to suction and retain impurities suspended in the pool water. After initial filtering treatment (until the swimming pool
water is clean), the whole volume of the pool should be recirculated once a day.
The filtering cartridge (No. 4) inside the Skimmer is the element that cleans the water. It consists of a fabric with a very fine mesh that retains
the dirt.
Frequency in cleaning the filter cartridge (No. 4) depends on the amount of dirt, the number of filtering hours and the volume of the swimming
pool. When it is observed that the amount of water returned inside the pool decreases, the filtering cartridge should be cleaned and replaced if
necessary.
Filtering needs depend on the volume in m
Turn the motor off for at least 2 hours between operation intervals.
The aforementioned off time should be followed in the initial filtering treatment. It is recommended to increase the filtering time as the water
temperature of the pool increases.
NEVER PLACE CHEMICAL PRODUCTS IN THE BASKET OR CARTRIDGE, AS THIS WILL DAMAGE THE MATERIALS OF THE

5. OPERATION

The cartridge inside the backpack Skimmer is the element that cleans the water. It consists of a fabric with a very fine mesh that retains the
dirt.
Frequency in cleaning the cartridge depends on the periods of use of the filter, the environment, trees, pollen, insects and how often the pool is
used, which are factors that determine the level of dirt of the pool.
When it is observed that the amount of water returned to the pool decreases, the cartridge should be cleaned (see section 6.1. Cleaning the
cartridge).
To maintain the pool water in good condition, chemical products must also be used as recommended by the manufacturer (chlorine, anti-algae
products, etc.).
The life span of the backpack filter will be longer if it is used for maximum periods of 4 hours. Daily filtering needs depend on the volume of
water in the swimming pool in relation to the 3.8 m
Leave the motor off for at least 2 hours between each operation period.

6. MAINTENANCE:

6.1. CLEANING THE CARTRIDGE
Disconnect the apparatus from the power supply.
Remove the cover and the basket.
Unscrew the cartridge from its position and remove it from inside the backpack Skimmer (Fig. 7).
Place the cartridge under a jet of water from a low-pressure garden hose, until it is clean (Fig. 6).
Insert the cartridge with the threaded end facing downwards and screw it back into place.
Place the pre-filter basket and cover back into place.
6.2. CLEANING THE FLOOR OF THE SWIMMING POOL
The backpack Skimmer can be used to clean the floor of the swimming pool, with one of the following or "Triangular" floor cleaner +
adapter cover / AR-2062.
