Section I - Safety precautions
7
11. The electrical connections must correspond to the applicable codes. The machines
must be earthed and protected against short circuits by fuses in all phases. A
lockable power isolating switch must be installed near the vacuum/overpressure
pump.
12. On machines with automatic start/stop system or if the automatic restart function
after voltage failure is activated, a sign stating
“
This machine may start without
warning
”
must be affixed near the instrument panel.
13. In multiple vacuum/overpressure pump systems, manual valves must be installed to
isolate each pump. Non-return valves (check valves) must not be relied upon for
isolating multiple systems.
14. Never remove or tamper with the safety devices, guards or insulation fitted on the
machine.
15. Piping or other parts with a temperature that exceeds 70°C (158°F) and which may
be accidentally touched by personnel in normal operation must be guarded or
insulated. Other high temperature piping must be clearly marked.
16. If the ground is not leveled or can be subject to variable inclination, consult the
manufacturer.
17. Whenever air containing hazardous substances are sucked in (that is, biological or
microbiological agents), use abatement systems placed upstream of the
vacuum/overpressure pump.
18. Any pump placed in an application with inlet gas stream temperatures above the
published maximum temperature should be approved by Quincy prior to start-up.
Also consult following safety precautions: Safety precautions during
operation and Safety precautions during maintenance or repair.
These precautions apply to machinery processing or consuming air
or inert gas.
Processing of any other gas requires additional safety precautions
typical to the application which are not included herein.
Some precautions are general and cover several machine types
and equipment; hence some statements may not apply to your
machine.
Safety precautions during operation
All responsibility for any damage or injury resulting from neglecting
these precautions, or non-observance of the normal caution and
care required for installation, operation, maintenance and repair,
even if not expressly stated, will be disclaimed by the manufacturer.
1. Never touch any piping or components of the pump during operation.
2. Use only the correct type and size of hose end fittings and connections. Make sure
that a hose is fully depressurized before disconnecting it.
3. Persons switching on remotely controlled machines shall take adequate precautions
to ensure that there is no one checking or working on the machine. To this end, a
suitable notice shall be affixed to the remote start equipment.
4. Never operate the machine when there is a possibility of taking inflammable or toxic
fumes, vapors or particles.
5. Never operate the machine below or in excess of its limit ratings.
6. Keep all bodywork panels shut during operation. The panels may be opened for
short periods only, for example, to carry out routine checks. Wear ear protectors
