2.4 Safety systems
Several safety systems have been conceived during the multi spray unit design and manufacture to
safeguard the operator, in compliance with pr EN 12621 Directive about paint.
INFORMATION ABOUT SAFETY
In case of units, which must work in an environment with a potentially explosive atmosphere the staff
in charge, before starting its activities, must disable the unit power supply, by putting it “out of order”
and by taking precautions against any condition, which can cause an accidental restart of the unit.
Moreover, all the other necessary environmental safety measures (for example the possible gas and
residual dust decontamination etc.) must be taken.
SAFETY VALVE
An 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 PLASTIC VALVE PROTECTION, ANY TAMPERING COULD BE
DANGEROUS FOR THE OPERATOR AND COULD COMPROMISE THE GOOD WORKING OF
THE EQUIPMENT.
BALL VALVE
IN CASE OF ANOMALIES DURING WORKING, TURN THE BALL VALVE LEVER 90°. IN
THIS WAY THE AIR SUPPLY WILL BE INTERRUPTED AND THE RESIDUAL PRESSURE INSIDE
THE PUMP WILL BE RELEASED.
