FITTING THE VOLTAGE CONVERTER

Check the voltage indicated on the side of the voltage converter.

Turn the indicator so that the desired voltage points towards the side with the "M" lock catch.

The arrow on the converter next to the required voltage must be aligned with the "F" arrow on the
housing.

Push the coverter into position until the reference catch "M" clips in place.

STARTING UP

9.1
Before starting up, check that the pump is properly primed; fill it completely with clean water by
means of the hole provided after having removed the filler cap on the pump body. This ensures
that the mechanical seal is well lubricated and that the pump immediately starts to work regularly.
(Fig. F). Dry operation causes irreparable damage to the mechanical seal. The filling cap
must then be screwed back on carefully.
10.

PRECAUTIONS

10.1 The pump should not be started more than 20 times in one hour so as not to subject the motor to
excessive thermal shock.
10.2 DANGER OF FROST: When the pump remains inactive for a long time at temperatures of
less than 32 °F (0°C), the pump body must be completely emptied through the drain cap Fig.
H, to prevent possible cracking of the hydraulic components. This operation is advisable even
in the event of prolonged inactivity at normal temperature.
10.3 When starting after long periods of inactivity, the starting-up operations listed above must be
repeated.

MODIFICATIONS AND SPARE PARTS

12.1

Removal and replacement of the supply cable

Unscrew the screw from the cover of the pressure switch using a screwdriver and remove the cover. Remove
the yellow-green lead, slackening the earth screw, the blue lead and the brown lead from the respective
terminals at the side, slackening the screws on the terminals.
slackening the respective screws, and slip off the cable which is now disconnected.
When replacing the power cable, a cable of the same type must be used and with the same terminals,
proceeding as for disassembly in inverse order.
ATTENTION:
For power cables with a plug, fit a device for disconnecting the power network (e.g. a magnetothermal
switch) with separation contacts of at least 0.12". for each pole.

INSTRUCTIONS FOR ADJUSTING THE PRESSURE SWITCH

1. Establish the minimum desired pressure value (leaving the pump).
2. Set the storage tank pre-loading pressure 42 psi (2.9 bar) less than the minimum pressure level.
3. Calibrate it following the indications given below inside the pressure box.
Do not start the pump unless it has been completely filled with
fluid.
In normal operation, the pump does not require any specific maintenance. However, it
may be necessary to clean the hydraulic parts when a decrease in performance is
observed. The pump must not be dismantled unless by skilled personnel in
possession of the qualifications required by the regulations in force. In any case,
all repairs and maintenance jobs must be carried out only after having disconnected
the pump from the power mains.
Any modification not authorized beforehand relieves the manufacturer of all
responsibility. All the spare parts used in repairs must be original ones and the
accessories must be approved by the manufacturer so as to be able to guarantee
maximum safety of the machines and systems in which they may be fitted.
Before starting, ensure that the pump is not connected to the power network
