Safety precautions
These symbols together with one of the words
“Danger” or “Warning” indicates the risk level deriving from failure
to observe the prescribed safety precautions:
DANGER Warns that failure to observe the precautions
Risk of involves a risk of electric shock.
electric shock
DANGER Warns that failure to observe the precautions
involves a risk of damage to persons and/or
things.
WARNING Warns that failure to observe the precautions
involves the risk of damaging the pump
and/or the plant.
1. GENERAL INFORMATION
Please observe the following instructions to achieve the best
pump performance possible and a trouble free installation.
The Ninfa series of pumps are vertical multistage units 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. The motor, enclosed
inside the pump casing is cooled by the discharge water.
These pumps have been designed to operate with clean water,
free of particles in suspension, with a maximum temperature
of 35 degrees Centigrade.
WARNING: correct pump operation is assured by follow-
ing the instructions on installation and use, and the elec-
tric connection drawings.
DANGER: failure to adhere to the instructions can
result in premature failure of the pump and voiding of
the warranty.
The lubricating oil in the motor is non toxic. In the case
of accidental discharge it will not affect the colour or
smell of the water and has no detrimental health
effects.
2. INSTALLATION
2.1 - Fixing
The pump should be suspended by a rope or chain above the
bottom of the well or tank. Care should be taken to ensure that
the pump is far enough away from the walls so as not to restrict
movement of the float switch.
Never suspend the pump by its electric cable or discharge
pipe.
On the automatic version, to vary the required water levels, it
is possible to adjust the height of the floating level switch in
relation to the pump by pulling the cable through its securing
clamp. Free movement must be guaranteed for correct opera-
tion of the float switch.
2.2 - Assembly of discharge pipes
Recommended discharge pipe size is 1". Smaller diameter
pipe will result in a loss of working head.
All pipework must be self supporting and not bear weight onto
the pump.
It is recommended to install a check valve in the discharge
pipework.
2.3 - Electrical connection
DANGER, risk of electric shock. Electrical installation
must be arranged with an effective earth connection and
comply with the prevailing national regulations.
Electrical connection will be made by connecting the
supply plug to a current outlet with corresponding earth
contacts.
System protection will comprise of a high sensitivity dif-
ferential switch (I
∆ν
= 30 mA).
The motor is fitted with a thermal cut-out protecting the
pump if overloading occurs.
2.4 - Pre-start checks
WARNING: ensure that the voltage and frequency of the
supply correspond to the values indicated on the fea-
tures label.
Ensure that the pump is completely submerged.
THE PUMP MUST NEVER BE DRY RUN.
3. OPERATION
Ensure all valves in the pipework are open.
Connect power supply. If the floating level switch is in the upper
position the pump will start. There will be a delay before water
appears at the end of the discharge pipe.
If the pump fails to operate refer to the possible faults, causes
and solutions list for assistance.
4. MAINTENANCE
For correct maintenance, please follow these instructions:
DANGER, risk of electric shock. Disconnect the pump
from the power supply before handling.
If the pump is not to be operated for a long period, it is
recommended that it is removed from the water, cleaned
and kept in a dry, well ventilated environment.
ATTENTION: In the event of faults or damage occurring
to the pump or its power supply cable, repairs should
only be carried out by an authorised service agent.
Under normal conditions these pumps are mainte-
nance free.
When the pump is eventually disposed, please note
that it contains no toxic or polluting material. Main com-
ponents are identified to allow selective disposal.
