ble, and that the exhaust air will not re-circulate towards the compressor air intake or the cooling air
inflow vent.
11. The electrical connections must conform to the applicable standards. The machines must be fitted
with a ground connection and protection fuses against short circuits on all phases. Near the compres-
sor, a lockable circuit breaker must be installed.
12. On machines with an automatic start-stop system, or if the function for automatic re-starting after
power interruptions is activated, a notice must be affixed next to the instrument panel, stating the
following "This machine can start suddenly without notice".
13. In systems with multiple compressors, manual valves must be installed that will isolate each com-
pressor. Never rely on non-return valves for insulating pressurised systems.
14. Do not remove or tamper with safety devices, protections or isolators fitted to the machine. Each
pressurised or auxiliary tank installed outside the machine to contain air whose pressure exceeds at-
mospheric pressure, must be protected by a pressure-discharging device or by compulsory devices.
15. Piping and other parts that can reach a temperature exceeding 80 °C (176 °F) and that could acciden-
tally be touched by personnel during normal operations, must have protection or be isolated. Other
high temperature pipes must be clearly marked accordingly.
16. Should the ground not be flat or should it be subject to variable inclinations, consult the manufacturer.
Furthermore, read the following safety precautions: Safety precautions during ope-
ration and during maintenance works.
These precautions apply to machinery that use or consume air or inert gasses.
The use of any other gas requires further safety precautions typical of this specific
application and are not included in this publication.
Several precautions are only of a general nature and refer to various types of
equipment and machines; it follows that some instructions may not apply to your
machine.
1.4 Safety precautions during operation
The manufacturer declines any responsibility whatsoever for damages or injuries
that may derive through failing to observe these precautions or normal caution and
through failure in providing the required attention for the installation, operation,
maintenance and repairs, even if not expressly quoted.
