SAFETY
2.1
GENERAL WARNINGS
It is important to read this manual before performing any operation on the pump. Compliance with the safety
standards of the country in which the pump is installed and requirements of qualified personnel for various
maintenance, use, installation, etc. are recommended throughout the life of the pump.
The main rules of conduct to be observed for operation at a suitable level of security are the following:
•
Installation, operation, maintenance, etc. operations should always be performed by qualified, trained personnel.
•
Without exception, always wear necessary personal protective equipment.
•
Always perform all cleaning, adjustment and maintenance operations with all power equipment cut off.
•
Do not direct water jets toward electrical parts, even if they are protected by enclosures.
•
Do not smoke during work or maintenance, especially where solvents or flammable materials are being used.
•
Do not damage symbol plaques or pictograms on the pump. If they should accidentally become damaged,
immediately replace them with other identification plaques.
D.V.P. Vacuum Technology S.r.l disclaims any liability for damage to persons or property resulting from improper
use of the pump, from tampering with its safety apparatus or failure to observe operational safety standards.
2.2
RESIDUAL RISKS
HAZARD
This pump has been designed to minimise residual risks to personnel. We urge you, however, to
take the utmost care and attention in carrying out maintenance operations. The confidence gained
with frequent contact with the pump too often leads users to forget or underestimate risks.
High temperature hazard
Pump surfaces can exceed a temperature of 70°C. Install the pump in a protected area that is accessible only by
authorised personnel and only perform operations when the pump is stopped and cooled.
Hazard generated by low pressure
Avoid contact with pump intake attachment during operation. Introduce air into the suction circuit before any
intervention. Contact with low pressure points can cause accidents.
Hazard generated by pressure
The pump tank is pressurised. Do not open and do not leave oil filler or drain plugs open during operation.
Danger from the emission of harmful substances
Pump outlet air contains traces of oil mist. Ensure compatibility with the working environment.
Faults or wearing of seals may cause oil lubricant leaks. Avoid dispersion in soil and pollution of other materials.
Whenever air containing hazardous substances are sucked in (i.e. biological or microbiological agents), use
abatement systems placed before the vacuum pump. Used oil must be disposed of according to applicable
regulations in the country of pump use.
