4. The coupling tolerances on the pump/transmission axis
(half-joint misalignment, Cardan joint tilt, belt pulling,
etc.) remain within limits required by the transmission
manufacturer.
5. Oil in the pump casing is at level, verified with a dipstick
(pos. , Fig. 14) and exceptionally with a level indicator
(pos. , Fig. 14).
In case of prolonged storage or long-term
inactivity, check proper functioning of the
suction and outlet valves.

Start-up

1. At first start-up, verify that the rotation direction and the
supply pressure are correct.
2. Start-up the pump without any load.
3. Check that the supply pressure is correct.
4. Check that the rotation rpm during operation does not
exceed the nominal rpm of the pump.
5. Let the pump run for a period of no less than 3 minutes,
before putting it under pressure.
6. Before each pump stop, reset pressure by means of the
control valve or with any relieving devices and reduce to a
minimum rpm (activation with combustion motors).

PUMP STORAGE

Long-term inactivity

If the pump is started for the first time after a long
period from the date of shipment, before operation
check the oil level, inspect the valves as specified
in chapter 10, then follow described start-up
procedures.
Method for filling pump with anti-corrosion
emulsion or anti-freeze solution
In place of the service tank, use a suitable container
containing the solution to be pumped.
Close the filter drainage, if open.
Make sure that the hoses to be used are clean inside and
spread grease on their connections.
Connect the high pressure exhaust pipe to the pump.
Connect the suction pipe to the diaphragm pump.
Connect the suction pipe between the pump head and
the diaphragm pump.
Fill the service container with solution/emulsion.
Insert the free ends of the suction pipes and the high
pressure exhaust pipe inside the container.
Switch on the diaphragm pump.
Pump the emulsion until it exits from the high pressure
exhaust pipe.
Continue pumping for at least another minute.
Stop the pump and remove the previously connected
pipes.
Clean, grease and plug the connections on the pump
head.

PRECAUTIONS AGAINST FROST

Follow the instructions in Chapter 12 in areas and
times of the year at risk of frost (see par. 12.2).
In the presence of ice, do not run the pump
for any reason until the circuit has been fully
defrosted, in order to avoid serious damage to
the pump.
