The pump will keep running as long as a tap is on.
When the taps are turned off, the pump stops.
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.
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
These pumps are designed for both indoor and
outdoor use.
Make sure that pump is never submerged and that
it rests in a dry and well aired room.
3.1. Fixing
The pump should be installed on a solid, horizontal
base, can be secured by screws or bolts using the
existing holes in the mount. Ensure that the pump
mount rests squarely on the base before fixing.
3.2. Suction pipe assembly
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.
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.
The end of the suction pipe must always remain at
least 30 cm below the water level (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.
Pipework must be supported and their weight must
not rest on the pump.
If a foot valve has not been installed it is recom-
mended to fit a check valve to prevent accidental
draining down of the system.
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
a
differential
switch
(∆fn = 30 mA)
The power cable must correspond at least to the
type H05 RN-F (according to 60245 IEC 57) 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.
Single-phase motor pumps have thermal
protection.
Follow instructions given on fig.1 for correct electri-
cal connection.
3.5. Pre-start checks
Ensure the voltage and frequency of the
supply corresponds to the values indicated
on the electrical data label.
Ensure that the pump shaft is rotating freely.
Fill the pump body with water through the self-
priming plug opening. If a foot valve has been
installed, also fill the suction pipe.
Check all joints and connections for leaks.
THIS PUMP MUST NEVER BE DRY RUN.
4. STARTING
Ensure all valves in the pipework are open.
Connect power supply. There will be a delay before
water appears at the end of the discharge pipe.
Viewings from the fan ensure that the rotation of the
motor is clockwise.
Ensure that the absorbed current is the same or
lower than the maximum shown on the name plate.
Adjust the thermal relay if is necessary.
If the pump fails to operate refer to the possible
faults, causes and solutions list for assistance.
The self-priming time can take several minutes.
4.1 - Starting up the pump with pressure
regulator (DORINOXMATIC)
Connect the electricity supply. The current indicator
LED (LINE+RUN) will light up.
The unit starts automatically. While the pump is
running the operating light will remain lit up (RUN).
During this operation keep an outlet tap open in
order to bleed any air from the installation. Once
the installation has been bled, close the tap and the
unit will then stop running in~10 seconds. Only the
electrical current indicator LED (LINE) will remain
lit.
If the pump is not well primed at start-up, or if there
is no water to supply to it, the pump will stop ten
seconds later and the (FAULT) indicator LED will
light up.
To complete priming of the pump, press the
(RESET) button.
See fig.6 for the distribution of the indication LEDs.
