6. STORAGE
All the pumps should be stored in a sheltered, dry, dust-free place, with regulated air-moisture levels when possible.
The pumps are supplied in their original packaging, where they must remain until assembly.If not, keep the suction
and discharge ports closed.
7. INSTALLATION
General
The pump should be installed as close as possible to the level of water, leaving a minimum of two metres to
the swimming pool edge in accordance with IEC publication No. 364 in a horizontal position, in order to obtain
minimum run length in suction and a reduction of load losses.
Sufficient space should be allowed for removing to pre-filter basket for cleaning and re-fitting.
The pump should be installed on a solid, very smooth surface. It is necessary to perfectly fit the pump through the two
holes provided for this purpose in the support base by means of two screws or other similar methods to prevent any
possible noise or vibration that could adversely affect the pump operation.
The pump should not be installed at a geometric height of more than 3.5 metres above the water level.
In order to obtain optimum pump self-priming, it should be installed at a maximum of 2.5 metres above the water
level.
The pump should be protected from any possible flooding and correct ventilation should be ensured, but without
risking the effects of freezing. In the case of outside installation, the pump should be protected from rain and a power
supply cable in accordance with EEC standards, type H07-Requirement Number-F (in accordance with VDE 0250)
should be installed. The pump is normally supplied without an electric power cable. In this case the pump test cables
can be seen to be cut at the outlet of the motor junction box. These cables must be replaced by a suitable electric hose
in accordance with the legislation in force in each country.
In the case of being installed a fibre housing, whether buried or half-buried, sufficient air flow should be guaranteed
to generate correct ventilation that prevents the maximum interior temperature from exceeding 40ºC.
Assembling the Piping
We recommend the installation of cut-off valves in both pump suction and impulsion so that the pump may
be removed from the installation without having to empty the whole circuit first.
The suction piping should be at least the same diameter as the pump connection, and it is also recommended that the
impulsion piping should also be the same diameter as the pump connection.
The suction piping should be assembled with a slight inclination towards the pump to prevent air pockets forming
inside.
