REQUIREMENTS FOR CORRECT INSTALLATION
This filter is easy to install and can be assembled by one adult in about 2 hours, taking care to follow the instructions detailed
in this manual correctly. Only the following tools are required to correctly handle the filter components and to install it:
Tighten the hose flanges
Tighten the pump screws
Cut the liner
Protection of collector pipe
2 BEFORE CONNECTING THE FILTER
LOCATION
Place the filter on a flat, solid surface at a minimum distance of 3.5 meters from the pool (in accordance with standard installation
regulations of electric equipment in swimming pools in force in each region or country) and at the same level as the bottom of the
pool to prevent air from entering the cleansing circuit and to ensure that the filter remains primed (fig. 2). The filter should be
protected from sun and rain, and kept in a sufficiently ventilated area during operation. Never cover it during operation.
In models where pool connection hoses are supplied, these will be 4.5 metres in length. In all cases, check that this length is
sufficient in order to install the apparatus on a flat, solid surface more than 3.5 metres away from the pool. If the hose length
is insufficient, contact your service centre.
When hoses are not supplied with the apparatus, hoses with a minimum length of 4.5 metres should be used which allow the
filtering equipment to be placed on a flat, solid surface more than 3.5 metres away from the pool. This hose set is available
as an optional kit from your vendor.
During the installation process, if in doubt, contact the vendor of the equipment
ASSEMBLY
Once the filter is set in place, proceed as follows:
• Fix the filter to the base. Depending on the monoblock filter (Fig. 0).
• Fix the pump to the base with the screws and washers supplied.
• Place the inner collector correctly on the bottom of the filter (Fig. 9).
• Cover the mouth of the collector situated on the inside of the filter with a plastic protector to make sure sand does not enter (Fig. 4).
• Put the sand inside the filter: The height of the sand should not exceed 2/3 of the height of the tank (Fig.4).
The silica sand lasts for an unlimited period of time. It should only be replaced if lost. Record the reference of the level of
silica sand for future replacement (Fig. 4).
• Remove the remains of sand from the filter opening and take off the protective plastic.
• Put the selector valve with its coupling and secure with the metal band or seal.
• Firmly tighten the screw on the metal band which joins the valve to the filter (fig. 3).
• Connect the (PUMP) and (RETURN) terminals of the selector valve to the corresponding hoses, tightening them firmly with
the clamps (Fig. 5).
NOTE: Check that the hoses allow the filtering equipment to be located and fixed on a flat, solid surface that is more than 3.5
metres from the pool.
• Connect the other end of the suction hose to the skimmer tightening firmly with a clamp. Repeat the same procedure with
the return 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 section 5.3.
