1. GENERAL INFORMATION
Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
Read these instructions before installing the
pump.
Save them for future reference.
These are single cell centrifugal pumps with built-in
filter elements, especially designed for prefiltering
and recirculation of water in swimming pools.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 104ºF.
Correct pump operation is assured providing
the instructions on electrical connection,
installation and use are strictly adhered to.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
together with one of the
2. HANDLING
The pumps are supplied suitably packaged to pre-
vent damage in transit. Before unpacking, check
that the packaging has not been damaged or de-
formed,
Lift and handle the product with care and with
the right tools.
3. INSTALLATION
The installation of these electric pumps is only
permitted in swimming pools or ponds that comply
with standards IEC 60364-7-702 and/or the national
regulations of the country in which the product is to
be installed.
3.1. Fixing
The pump should be installed on a solid, horizontal
base, secured by screws or bolts and using the
existing holes in the mount.
The pump should be protected from possible
flooding and receive dry ventilation.
3.2. Suction pipe assembly
The pumps must be installed at least 6.5ft from the
wall of the pool, and at the same height as the level
of the water, or if possible, below. The end of the
suction pipe must always remain at least 1ft below
the water level.
The suction pipe, if longer than 23ft, must be of the
same or greater diameter than the pump inlet and
installed in an upward inclination to prevent trapped
air pockets forming.
If the pump is required to perform a suction lift, to
avoid unnecessary losses of head on the discharge
side, the pump should be installed as close as
possible to the water. It is not advisable to install
the pump at more than 10ft geometrical height from
the water level.
3.3. Discharge pipe assembly
It is recommended to use pipes with a diameter
equal or greater than the pump outlet. This will
reduce loss of head caused by friction in longer
pipe runs.
Pipework must be supported and their weight must
not rest on the pump.

3.4. Electrical connection

The electrical installation must have a multi-
pole isolator with minimum 1/8" contact
openings, The protection of the system will
be based
(Δfn = 30 mA)
The power cable must correspond at least to the
type H07 RN-F (according to 60245 IEC 66) and
having terminals.
The connection and its dimensioning must be per-
formed by a qualified installer according to the
needs of the facility and following the regulations in
force in each country.
