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-stage,
pumps specially designed for recirculation of large
water flows in swimming pools for applications in
counterflow current installations.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 40ºC.
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.
direct-suction centrifugal
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.
For correct pump ventilation, leave a space of at
least 10cm between the ventilator cover and any
other element that might obstruct air circulation.
(Fig.4)
3.2. Suction pipe assembly
The suction pipe 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 3m geometrical height from
the water level. (Fig.4)
The non-return valve must be fitted correctly in the
suction inlet. The latter must be positioned with the
suction connector pivot and ALWAYS oriented with
the larger metal ring against the suction inlet of the
pump body (Fig.3).
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.
For tubes made of plastic materials the threaded
joints must be made
"TEFLON" tape. No adhesives or similar products
should be used.
For interior screw threads, when screwing in the
respective tubes never exceed the length of the
interior screw threads.
connectors should be used.
Pipework must be supported and their weight must
not rest on the pump.
