18. GROUND CONDUCTOR CONNECTIONS
The Yellow/Green ground terminal in the electric pump cable must be connected to the grounding circuit of the system before the
other terminals are connected. Furthermore, it must be the last terminal to be disconnected if the electric pump is disconnected.
terminal with the grounding circuit of the system is at the installer's charge.

ATTENTION
has been exceeded, the switches open and interrupt the power supply to the remote control coil, thus stopping the electric
supply is recommended.
19.2 CONDUCTIVITY PROBE (standard supply on version K...+...X... only)
WARNING
The terminals of the probe circuit are the conductor bearing the "S" symbol and a shunt from the Yellow/Green earth conductor. If the electric panel
is equipped with the relative device, this will activate when the electric resistance of the circuit drops to below 30kΩ owing to the presence of water.
The conductivity detector is generally used to close an alarm circuit (lights and/or acoustic) if water is detected near the probe.
20. PREVENTIVE MAINTENANCE INSPECTIONS
To ensure regular pump operation and long life, the purchaser must ensure that regular inspections and periodic maintenance operations are carried
out, with replacement of any worn parts. It is advisable to carry out the below listed preventive inspections at least once a month, or after every 200-
300 hours service:
- check that the power supply voltage is within the established values;
- using an amperometric clamp, check that the power draws on the three phases are balanced and that they do not exceed the data plate values;
- check the motor insulation: detach the power cable from the panel and connect the joined cable terminals and the ground cable to the terminals of
a 500 V.d.c. ohmmeter. The insulation resistance (motor-cable) must not be less than 5MΩ. Failing this, pull out the unit and overhaul (a cable will
need replacing or the motor must be repaired). Further inspections for electric pumps equipped with the following devices:
- check the oil conductivity which must be >30KW, if the electric panel is without the relative warning light;
Ask Caprari SpA for their "Periodic inspections and preventive maintenance" publication, document N° 0023450 for more detailed and scheduled
maintenance work.
21. OIL AND GREASE INSPECTION AND CHANGE
In normal conditions of work, the oil must be changed every 7500 hours and every 2500 hours in heavy duty situations. Use the oils listed
below or similar ones.
emptying, the machine should be set in a horizontal position. If the drained oil is like an emulsion, change it for new oil and check the condition
of the seal on the pump side.
Change the mechanical seal on the pump side if there is water together with the oil in the reservoir. The mechanical seal on the motor side
