SAFETY
2.1
GENERAL WARNINGS
It is important to read this manual before performing any kind of work on the side channel turbine. Compliance with
the safety standards of the country in which the turbine is installed and employment of qualified personnel to carry
out maintenance, use, installation, etc. operations are recommended throughout the life of the turbine.
The main rules of conduct to be observed for operation at a suitable level of security are as follows:
Installation, use, maintenance, etc. should always be performed by qualified and trained personnel.
It is essential to wear the necessary personal protective equipment at all times.
Always perform all cleaning, adjustment and maintenance operations with all power supplies disconnected.
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 plats or pictograms on the turbine. If they should accidentally become damaged,
immediately replace them with other identical plates.
D.V.P. Vacuum Technology s.p.a. disclaims any liability for damage to persons or property resulting from improper
use of the turbine, tampering with its safety apparatus or failure to observe operational safety standards.

ADDITIONAL RISKS
HAZARD
This side channel turbine 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 turbine too often leads users to forget or
underestimate risks.
Entanglement hazard
There is a permanent impending hazard of entangling or entrapping hair and clothing in the cooler fan inside the
protection itself near the fan cover casing on the electric motor.
Tie long hair up and do not wear baggy clothing, long laces or other items that could get caught up.
Hazard of cutting and/or shearing caused by moving rotor
Via the openings in the intake and outlet silencers it is possible to access the rotating rotor.
Never insert your hands or any kind of object through the openings.
This hazard also exists when the machine is not moving, when it is started up manually.
Hazard generated by the turbine seizure.
Failure to comply with the instructions for use set out in this manual could cause turbine seizure. Should you hear
an unusual noise that might be turbine rotor seizure, move away and turn the machine off immediately.
Hazard generated by a noise created by the turbine
When the side channel turbine is operating, it gives off a noise that can exceed 80 dB(A); if this occurs, follow the
instructions in point 3.2 of this manual.
High temperature hazard
Under working conditions, in compliance with the levels indicated in point 3.3, the turbine's surfaces can exceed a
temperature of 70°C. Install the turbine in a protected area that complies with the surrounding conditions set out
in point 3.3 of this manual, accessible only to authorised personnel. Do not voluntarily touch the surfaces of the
unit while working and only carry out repair work when the turbine is off and cool.
Hazard generated by overpressure and process fluids that escape at high temperature
Process fluids can escape from the safety devices (overpressure valves) prescribed for the use of the turbine in
compression and connection piping, at high temperature and can cause burning.
Use fitting and connecting parts to the system's piping that can sufficiently resist the pressure and temperatures
that arise and install safety devices in positions that cannot create hazardous situations for personnel including
while the turbine is working.
Hazard generated by low pressure
Avoid contact with turbine intake while operating. Use fitting and connecting parts to the system's piping that can
sufficiently resist the vacuum that arises. Let air into the intake circuit before any intervention. Contact with vacuum
points can result in accidents due to hair and/or clothing being sucked in; this can also occur close to safety
devices.
Hazard from the emission of harmful substances
Whenever air containing hazardous substances is sucked in (i.e. biological or microbiological agents), use
abatement systems located in front of the turbine and divert the exhaust to a protected area.
