- The pump has to be
installed on a base plate
➀
.
- The basement has to be made of electric
welded steel and fit for the pump dimensions,
with leveled face
➁
.
- The pump has to be strongly fastened to the
basement by clamping screws.
- The basement has to have a frame to sup-
port the suction
➂
and discharge
➃
pipeli-
nes and possible accessories (pulsation dam-
pers, pressure gauges, valves) and not vibrate
while the pump is working.
Protection against accidental leakages
of aggressive pressurized fluids.
- For a proper connection of the electrical
motor follow the illustrated instructions.
- Protect the motor by installing a magneto-
thermic device, fit to the power input values of
the motor, knowing that the motor, at start,
absorbs at least four times the motor nominal
power.
- Earth the terminal of the motor casing, using
a cable with at least 6 mm
2
section
➄
.
-Check the direction of rotation of the motor
(see the arrow on the motor body); if the
direction of rotation is not in accordance with
the arrow, interchange two wires:
1 on 2, 2 on 1.
WARNING:
Start the motor only when the terminal box
is closed
- Check the oil level.
- Open all the on-off valves both along the
discharge and suction pipeline
➅
.
- Check the relief valve installation and its
discharge into the feeding tank
➆
.
WARNING:
Do not start the pump without a
safety valve.
- Check the pressure gauge installation
➇
(essential to check the pump status).
- Check the pulsation dampener
➈
(essential
for flowrates above 100 L/h).
- Start the pump with adjustment set to 20 %
increase gradually the flowrate (acting on the
adjustment knob) and find the relevant pres-
sure on the pressure gauge.
WARNING:
The working pressure must not exceed the
rating plate value.
- Check during the first three working hours
the pump body temperature (max 40°C) as
well as the motor temperature (max 80°C).
- Check periodically the oil level through the
oil-windows located on the pump body.
First three months, once a month afterwards,
once every four months.
- Check periodically (once every four months)
the pump status:
- Pump body temperature (max 40°C).
- Motor body (max 70°C).
- Working pressure (must not exceed the
rating plate value).
- Noise (within normal conditions must not
exceed 85 dbA).
- In order to avoid damages due to diaph-
ragm breaking it is advisable to replace the
diaphragm according to the pump use as
shown in the table.
- For disassembly and re-assembling see
instructions at page 14.
