USE OF THE PUMP

4.1

How to start the pump

Refer to the documentation supplied with the control unit when carrying out the following
operations.
Start the pump in compliance with the following instructions:
1. Reset the delivery pressure by means of the control unit, so as to bring it to the by-
pass position.
2.
Allow the pump to run for a few minutes at low speed so that the pressure does not
exceed ¾ of its maximum value. This is very important, as it allows all the
components in the pump to be correctly lubricated.
3.
Increase the speed of the pump so that it is able to prime. Rotation speeds that
exceed the maximum limit shown on the
the pump, but will cause unnecessary damage. Do not drop below the minimum
revolution speed indicated on the label. The manufacturer shall not be liable for
damage caused by rotation speeds exceeding those indicated on the label.
4. Set the control unit to the "Press" position.
5. Turn the knob of the control unit until the required pressure value has been
reached.
6.
During use, make sure that the oil level does not exceed the value indicated on the
filler (MIax level) or halfway up the filler itself when the pump is on pressure.
Frequently check the colour of the oil, which must not change from its initial
condition. If this happens, stop the pump and contact a skilled Technician.
7. Check the pump pulsations and change the pressure of the accumulator if
necessary, as described in the "PRELIMINARY OPERATIONS" section.
