3. SAFETY
3.1 General Safety Indications
Improper use of pumps and high pressure systems, and/or failure to observe the installation and maintenance
instructions may cause serious injury to people and/or damage to property. Anyone assembling or using high pressure
systems must possess the necessary competence to do so, should be aware of the characteristics of the components
assembled/used, and must take all precautions necessary to ensure maximum safety in any operating condition. In the
interest of safety, both for the Installer and the Operator, no reasonably applicable precaution should be omitted.
3.2 High pressure unit safety requirements
1. The pressure line must always be equipped with a safety valve.
2. igh pressure system components, in particular for those units working outside, must be adequately
protected against rain, frost and heat.
3. The electrical control system must be adequately protected from water spray, and must comply with the
specific regulations in force.
4. igh pressure hoses must be properly sized for maximum operating pressure of the system and always and only
used within the operating pressure range specified by the hose manufacturer. The same rules should be observed
for all other auxiliary systems affected by high pressure.
5. The ends of high pressure hoses must be sheathed and secured to a solid structure to prevent dangerous
whiplash in case of bursting or broken connections.
6. Appropriate safety guards must be provided for the pump transmission systems (couplings, pulleys and belts,
auxiliary drives).
3.3 Safety During Operation
The working area of a high pressure system must be clearly marked. Access must be prohibited to un-authorized
personnel and, wherever possible, the area should restricted or fenced. The personnel authorized to access this area
should first be trained, and informed about the risks that may arise from failures or malfunctions of the high pressure unit.
Before starting the unit, the operator must verify that:
1. The high pressure system is properly fed by a minimum pressure of 75-100 PSI (5-7 Bar), metered in the head
flange.
2. The pump intake filters are perfectly clean; we recommend the use of a device that indicates the filters clogging level.
3. Electrical parts are adequately protected and in perfect condition.
4. The high pressure hoses do not show evident signs of abrasion, and that fittings are in perfect shape.
Any fault or reasonable doubt that may arise before or during operation should be promptly reported and verified by
competent personnel. In these cases, pressure should immediately be released and the high pressure system
stopped.
3.4 General Procedures For Using ances
1. The Operator must always place his own and other worker’s safety before any other interest; his and should always
be governed by good sense and responsibility.
2. The Operator must always wear a helmet with a protective visor, waterproof clothing, and appropriate boots capable
of guaranteeing grip on wet pavement.

Note: appropriate clothing will effectively protect against water spray, but it may not offer adequate protection against the
direct impact of water jets or sprays from a close distance. Some circumstances may require further protection.
3. It is generally best to organize personnel into teams of at least two people capable of giving mutual and immediate
assistance in case of necessity and of taking turns during long and demanding operation.
4. Access to the work area that is within the water jets’ range must be absolutely prohibited to and free from objects
that, inadvertently under a pressure jet, can be damaged and or create dangerous situations.
5. The water jet must only and always be directed in the direction of the work area, including during testing or
preliminary tests or checks..
6. The Operator must always pay attention to the trajectory of the debris removed by the water jet. If necessary,
suitable guards must be provided by the Operator to protect anything that may be accidentally exposed.
7. The Operator should not be distracted for any reason during operation. Workers needing to access the operating
area must wait for the Operator to stop work, and then immediately make their presence known.
8. For safety reasons, it is important that each member of the team is fully aware of the intentions and actions of
other team members in order to avoid dangerous misunderstandings.
9. The high pressure system must not be started up and run under pressure without all team members in position
and without the Operator having already directed his/her lance toward the work area.
3.5 Safety During System Maintenance
1. The pressure system maintenance must be carried out in the time intervals set by the manufacturer who is
responsible for the whole group according to law.
2. Maintenance should always be carried out by trained and authorized personnel.
3. Assembly and disassembly of the pump and its various components must be performed exclusively by authorized
personnel, using appropriate equipment in order to avoid damage to components and connections.
4. Always use original spare parts to ensure total reliability and safety.
4. PUMP IDENTIFICATION
Each pump has a specific label which contains:
Pump model and version
Serial Number
Maximum RPM
Power - p-kW
Pressure - PSI
Flow Rate - GPM
Pump model, version and serial number must always
be specified when ordering spare parts.
