Always comply with all the safety, accident-prevention and anti-pollution instructions in the manual during each individual operation, together with all
the more restrictive local provisions in force.
The motor and pump, when these operate with hot water, can reach surface temperatures which could scorch the skin. Take due care.
Do not use water for extinguishing purposes if the electrical equipment catches fire.
For safety reasons and to ensure compliance with the warranty conditions, the purchaser must not use the pump should this become faulty or in the
event of a sudden variation in the performances of the pump itself.

DESCRIPTION OF THE PRODUCT AND USE

3.1 Technical and operative characteristics
The electric pumps have several centrifugal impellers in series, turning in an anticlockwise direction (viewed from the electric motor side). They are
directly coupled to special enclosed electric motors with IP55 protection degree (in compliance with EN 60034-5 standards).
When the product is installed according to the instructions given in this manual and in compliance with the diagrams, the acoustic pressure level issued
by the machine reaches the cautionary values in dB(A) given in the table in chapter 11 "Technical data, dimensions and weights".
In particular:
- the noise was measured according to ISO 3746;
- according to Directive EC, the gauging points were 1 meter from the reference surface of the machine and 1.6 meters from ground or access platform
level;
- the maximum value is on the fan side of the electric motor;
- the values have a +/- 3 dB(A) tolerance;
- the pump values were gauged at maximum efficiency point;
- the motor values were gauged during no-load operation.
3.2 Fields of use
The standard version of the product has been designed to pump clear water from accumulation tanks or to raise the pressure in boosters.
3.3 Inadvisable uses: ATTENTION
The standard product is not suitable for:
- dry operation, strictly comply with the following minimum flow rates for operation:
- pumping fluids other than clear water, that are chemically and mechanically not aggressive;
- pumping liquids with a temperature exceeding 90°C (194°F);
- pumping inflammable fluids;
- operation in places liable to explosion hazards;
- closed valve operation for longer than 2 minutes;
- operation with frequent stops/starts (maximum number of equally distributed starts/hour = 30);
- operation at altitudes exceeding 1000 m (may vary according to the installed electric motor);
- operation at ambient temperatures exceeding 40 °C (may vary according to the installed electric motor);
- at a suction pressure less than the required NPSH (consult the technical documentation of Caprari S.p.A.);
- a maximum suction pressure exceeding 6 bar (compatible with the operating pressure);
- an operating pressure 25 bar.
Remember to check that the product conforms with any pertinent local regulations.

STORAGE AND HANDLING

Store the pump in a dry and dust-free place.
Avoid instability which could be caused by wrongly positioning the product.
ATTENTION For safe storage after a previous installation, the pump must be thoroughly cleaned (never ever use hydrocarbon based products for
this purpose).
