2 BEFORE CONNECTING THE FILTER
Location
Place the filter on a flat, solid surface at a minimum distance of 3.5 metres from the pool , (Fig. 2) (in accordance with
standard NF C15-100 or the equivalent standard of the region or country) and at the same level as the bottom of the pool
to prevent air from entering the cleansing circuit and the filter from becoming unprimed. The filter should be protected
from sun and rain, and kept it in an area with sufficient ventilation during operation. Never cover it during operation.
Assembly
After the filter has been set into place, proceed as follows:
You will find instruction sheets with the equipment which show you the steps to follow when starting to assemble the
equipment
• Place the inner collector properly on the bottom of the filter (Fig. 6).
• Insert inside the filter 100 Kg of sand for AR720. Insert inside the filter 200 Kg of sand for AR725. The silica sand lasts
for an unlimited period of time and should only be replaced in the event of sand loss. Record the sand level for future
replacement. Keep the remaining sand in the bag in a dry place (Fig.5).
• Eliminate the remains of sand from the filter opening and remove the protective plastic.
• Place the TOP selector valve with its coupling and secure with the plastic band or seal following the diagrams in the
instructions attached to the metal plastic.
• Tighten firmly the screw on the plastic band (Fig.4), which joins the valve to the filter.
• Cover the opening of the inner collector tube with protective plastic in order to prevent sand from entering the tube.
• Connect the suction and discharge hoses to the suction and discharge terminals on the valve, tightening them firmly
with the clamps (Fig.9, Fig.10).
• Insert the Teflon supplied on the thread of the skimmer terminal and connect the other end of the suction hose.
Tighten firmly with a clamp. Repeat the same procedure with the feedback nozzle terminal and connect the discharge
hose.
• Following installation, the first cycle of filter backwash should be performed. In order to do so, follow the instructions in
the section 5.3.

The pump must be connected to a 220/230 V. alternating current and 50 Hz power point, with earth connection.
Consumption: 240 W.
An omnipolar switch must be used to ensure there is no power feed to the filter when it is not in use. A 30 mA differential
must also be used to protect from electrical breakdowns. (Not supplied. These items can be purchased at electricity
shops.)
4 UPPER SELECTOR VALVE
The upper selector valve is responsible for selecting the 6 different filter functions: backwash, recirculation, rinse, filter,
