3. SAFETY
3.1 General safety warnings
Improper use of pumps and high-pressure systems, and/or failure to observe the installation and
maintenance instructions, can cause serious injury to persons and/or damage to property. Anyone preparing
to assemble or use high-pressure systems must have the necessary skills to do so, must be aware of the
characteristics of the components to be assembled/used, and must adopt all possible precautions necessary
to ensure maximum levels of safety in any operating condition. No reasonably applicable precaution must be
omitted in the interests of safety, either by the installer or the operator.
3.2 Essential safety elements in the high-pressure system.
1. The pressure line must always have a safety valve.
2. The components of the high pressure system, particularly for systems that operate predominantly
outdoors, must be adequately protected from rain, cold and heat.
3. The electrical parts of the system, as well as being adequately protected from water sprays, must
meet the standards specified in the regulations currently in force.
4. High-pressure pipes must be correctly dimensioned for the maximum operating pressure of the
system, and must always and only be used within the range of working pressures indicated by the
maker of the pipe.
1. These precautions must be observed for all other accessories of the system which are connected in
any way with high pressure.
5. The ends of high-pressure pipes must be sheathed and anchored to a solid structure, to prevent
dangerous whiplashes in the event of bursting or breakage of the connections.
6. Suitable protective casings must be installed at the pump transmission systems (junctions, belts and
pulleys, auxiliary power take-offs).
3.3 Safety during operation.
The environment or area within which a high-pressure system operates must be clearly indicated and access
prohibited to unauthorised personnel and, as far as possible, it must be restricted and/or fenced off.
Personnel who are authorised to access this area must be trained in advance on how to conduct themselves
in this area, and they must be informed of the risks deriving from defects or malfunctions of the high-pressure
system.
Before starting the system, the Operator is required to verify that:
1. The high-pressure system is correctly fed by a minimum pressure of 5-7 bar (metered in the head
flange).
2. The pump inlet filters are perfectly clean; we recommend inserting a device (any type) that indicates
the level of congestion.
3. The electrical parts are adequately protected and in perfect working order.
4. The high-pressure pipes do not show any evident signs of abrasion and the fittings are in perfect
order.
Any anomaly or reasonable doubt that may arise before or during operation must be immediately reported
and checked by qualified and authorised personnel. In such cases the pressure must immediately be
brought down to zero and the high-pressure system must be stopped.
3.4 Instructions for using nozzles.
1. The operator must always put his/her health and safety, and also the health and safety of third
parties that may be directly affected by the operator's actions, above all else and above any other
interest. Everything the operator does must be dictated by good sense and responsibility.
2. The operator must always wear a hard hat with a protective visor, impermeable clothing, and
suitable boots that will provide a good grip on the floor when it is wet.
