Electrical Connection - GRE AR-125 Manuel D'installation Et D'entretien

PRIOR TO INSTALLATION
Before installing the Skimmer in the swimming pool, site the pool such that the stamp marking the Skimmer position faces the prevailing winds
(see Fig. 2) so that the winds help convey the dirt remaining on the pool surface toward the Skimmer mouth.
Follow the mounting instructions for the pool sheeting and liner carefully.
The Skimmer must be installed on the outside and high part of the pool wall.
The device is intended to collect the surface water, leaving large impurities in the prefilter basket and letting small ones pass through so they
are retained in the cartridge filter.
THIS WILL DAMAGE THE MATERIALS OF THE DEVICE AND LIMIT ITS EFFICIENCY.
4. ASSEMBLY:
The Skimmer body houses the filtering element or cartridge filter. The bottom of the body
also houses the motor and the turbine that circulate the water, which is collected at the top
through the Skimmer mouth and is returned through the lower valve once it is filtered.
4.1. RUCKSACK SKIMMER INSTALLATION
4.1.1. PRE-ANCHORING THE RETURN NOZZLE OF THE BACKPACK SKIMMER (Fig.2)
The filtered water flows through this nozzle into the pool again and the filtering cycle is then
finished.
Start filling the pool with water, stopping at around 4 cm. from the lower edge of the return
valve opening.
Mark the opening with a felt-tip pen and cut a cross in the centre of the opening using a
cutter (BLADE), without going over the pre-cut hole.
Insert the friction ring and one of the joints ( Fig. 2) in the return nozzle. From inside the
pool, insert the return nozzle with the friction ring and the joint through the cut. The pieces of
liner that stick out through the outer part of the pool should be cut cleanly and neatly.
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
DO NOT PLACE CHEMICALS IN THE BASKET OR THROUGH THE FILTER.
