A Warning! Observe limitations of use.
I
This apparatus may be used by children older
than 8 and persons with reduced physical,
sensory or mental capacities, or lacking
experience
and
knowledge,
if
they
are
supervised or receive adequate training on the
safe use of the apparatus and understand the
dangers.
Children should not be allowed to play with the
apparatus.
Children should not perform the ordinary
cleaning
and
maintenance
tasks
without
supervision.
B The name plate voltage must be the same as the
mains voltage.
C Connect the pump to the mains via an omnipolar
switch with at least a 3 mm opening between
contacts.
D Install a high-sensitivity differential switch (0.03A)
as extra protection against lethal electric shocks.
E Connect the pump to the ground.
F Use pump only within performance limits
indicated on the name plate.
J Be careful with hazardous liquids and
environments.
G
Remember to prime pump.
K
Caution! Look out for accidental leaks.
Do not expose pump to bad weather.
H
Check for motor self-ventilation.
L
Caution! Avoid icing.
Cut out power supply before servicing pump.

Safety precautions
This symbol
together with one of the
following words “Danger” or “Warning” indicates the
risk level deriving from failure to observe the
prescribed safety precautions:
DANGER
risk of
electric
shock
Warns that failure to observe
the pre cautions involves a
risk of electric shock.
DANGER
Warns that failure to observe
the pre cautions involves a
risk of damage to persons
and/or things.
WARNING
Warns that failure to observe
the pre cautions involves the
risk of damaging the pump
and/or the facility
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 self-priming horizontal multistage
centrifugal pumps having more than one impeller
assembled in-line. The same flow passes through
each impeller but the pressure increases each time,
i.e. more impellers, more pressure.
All models are manufactured to include a
recirculation system with automatic valve achieving
suction lifts of up to nine meters. By using a foot
valve on the suction pipe the pump will rapidly self-
prime when operated.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 40 ºC.
1.1. General information MATIC/CONTROL
The DORINOXMATIC model incorporate a built-in
electronic pressure regulator, made up of a check
valve, indicator LEDs and reset button. The start-up
pressure is equal to PA (fig.2). It have been
developed to automate start-up and stoppage and
to prevent the pump running without water.
The DORINOXCONTROL model incorporate a
built-in electronic no-water protection device, made
up of a check valve, indicator LEDs and an ON
button. It have been developed to prevent the pump
running without water.
They require no air recharge.
As long as the water consumption exceeds
1.4l/minute the pump will keep running.
