2.4 Safety systems
Several safety systems have been conceived during the airless unit design and manufacture to
safeguard the operator, in compliance with pr EN 12621 Directive about paint.
SAFETY INFORMATION
In case of units that are to be used in areas with potentially explosive atmospheres, before starting
working the operators must disable the unit power supply, by putting it “out of order”. They also
must ensure that the unit cannot be restarted unintentionally.
All further necessary environmental safety measures must be adopted (such as the elimination of
gas or residual dusts, etc.).
SAFETY VALVE
A 8 bar calibrated safety valve is installed to ensure the pump working pressure does not exceed
the limits inside the feeding circuit.
If the calibration pressure is exceeded, the valve opens by releasing the excess of air.
WARNING
DO NOT REMOVE THE VALVE PLASTIC PROTECTION. ANY TAMPERING WITH COULD BE
DANGEROUS FOR THE OPERATOR AND COMPROMISE THE EQUIPMENT GOOD WORKING.
BALL VALVE
In case of anomalies during working, turn 90° the ball valve lever. In this way the air supply will
be interrupted and the residual pressure inside the pump will be released.
