TRANSPORT AND STORAGE

The electric pump is very heavy. It must be handled by the indicated points using suitable and approved tools.
ATTENTION During transport and storage, keep the electric pump resting on the three feet built into the intake support, in a vertical position and
with the cable wound around the motor casing. This is the most stable position and protects the cable against possible contacts or
rubbing. Always check that the machine is stable in order to prevent it from rolling or dropping since this could damage persons,
property or the electric pump itself.
Never lift the electric pump by the powering cables. Use the handle provided on the cover of the motor casing (shackle in
the hole on the delivery port side).
WARNING When the electric pump has been stored, it must be kept in a dry place at a temperature of less than 60°C prior to being used
for the first time.
WARNING When the electric pump is stored after a period of use, it must be thoroughly cleaned with water and disinfected if necessary,
dried and kept in a dry place at a temperature of less than 60°C.
Before using the electric pump again, make sure that the rotor is free to turn before making the electrical connections, that the
motor's electrical insulation is undamaged and that the oil is at the right level.
If the electric pump is stored for a long period of time, turn the rotor every so often to prevent its seals and shims from jamming
(channel impellers).
If the pump is blocked by ice, immerse it in water until it has completely thawed. Do not opt for other, faster methods as the
machine could be damaged. Make sure that the pump is in a perfect condition and conduct the inspections described above
before use.
16. PRELIMINARY INSPECTIONS
ATTENTION The electric pump may only be installed after a few simple inspections have been made.
1. The electric pump is supplied ready for use with the correct amount of oil. After a long period at a
standstill, check that there is the right quantity of oil in the "oil chamber" (consult the relative "OIL
CHANGE" paragraph).
2. Check that the pump is not connected to the electricity supply line and then work through the intake
mouth to check that the rotor turns smoothly.
Never carry out any operation with the hands, particularly on pumps with shredders.
Always use tools.
3. Connect the powering cables to the Control Panel (see paragraph 18).
The terminals of the power cable are marked with international IEC codes. The electric pump will
only turn in the right direction if the terminals are correctly connected to the L1(u), L2(v), L3(w)
line. If the installed unit is visible during the starting phase, it will be subjected to a kick-back in an
anti-clockwise direction (see Fig. 1).
ATTENTION In electric pumps with shredders, an incorrect rotation direction will not appreciably
lower the performances or cause strong vibrations, but will mainly cause the
shredder to operate in an inefficient way, rapidly clogging the suction part.
17. ELECTRICAL CONNECTIONS
Make sure that the electric control panel corresponds to the national rules in force.
Particularly make sure that its protection degree suits the installation site. It is advisable to install the
electrical equipment in a dry place. Failing this, special versions of the equipment should be used.
ATTENTION The contacts of under-sized or poor quality electrical equipment will quickly deteriorate. This
will lead to an unbalanced power supply for the motor which could damage it. Unless correctly researched and installed, use of Inverters and
Soft-starters can damage the pumping unit. Ask for assistance from the Caprari Technical Departments if in doubt.
Safe and reliable operation can only be ensured if good quality equipment is installed.
All starting equipment must always be equipped with :
1) a main knife switch with a gap of at least 3 mm between its contacts and an appropriate device to lock it in the open position;
2) a suitable thermic motor protector device calibrated for a maximum power draw no higher than 5% of the current rating indicated on the motor
data plate and with an activation time of less than 30 seconds;
3) a suitable magnetic device to protect the cables against short-circuits;
4) a suitable device to protect the electric pump against earth faults;
5) a suitable phase failure protection device;
6) a device to protect against dry runs;
7) a voltmeter and an amperometer.
The engineer who designs the plant must make sure that the power supply system is protected against unwanted and accidental start-ups due to
the power supply suddenly returning after a blackout.
The electrical connections must be made by qualified personnel in strict compliance with all the national rules of installation (Italy CEI 64-8) and according
to the wiring diagrams enclosed with the control panels. Check that the voltage and frequency values on the electric pump data plate correspond to
those of the electricity main.
