The pump should be installed on a solid, horizontal
base, secured by screws or bolts and using the
existing holes in the mount.
Safety precautions
The pump should be protected from possible
flooding and receive dry ventilation.

.2. Suction pipe assembly
following words “Danger” or “Warning” indicates the
risk level deriving from failure to observe the
prescribed safety precautions:
The pumps must be installed at least two meters
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 30
cm below the water level.
DANGER
Warns that failure to observe
the pre cautions involves a
risk of electric shock.
risk of
electric
shock
The suction pipe, if longer than 7 meters, must be
of the same or greater diameter than the pump inlet
and installed in an upward inclination to prevent
trapped air pockets forming.
DANGER
Warns that failure to observe
the pre cautions involves a
risk of damage to persons
and/or things.
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 3m geometrical height from
the water level.
WARNING Warns that failure to observe
the pre cautions involves the
risk of damaging the pump
and/or the facility
1. GENERAL INFORMATION
3.3. Discharge pipe assembly
Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
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.
Read these instructions before installing the
pump.
Pipework must be supported and their weight must
not rest on 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.
3.4. Electrical connection
The electrical installation must have a multi-
pole isolator with minimum 3 mm contact
openings, The protection of the system will
be based on
(Δfn = 30 mA)
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 40ºC.
a
differential switch
Correct pump operation is assured providing
the instructions on electrical connection,
installation and use are strictly adhered to.
The power cable must correspond at least to the
type H07 RN-F (according to 60245 IEC 66) and
having terminals.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
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.
