SAFETY INSTRUCTION
Instructions for building into a system
PIAB vacuum conveyors are CE marked. The person
who installs the conveyor in another main system has
the responsibility of carrying out a risk analysis when
this is desired.
Dust explosions
When handling and conveying dry powders and mate-
rial consisting of small particles, there is a risk that a
dust explosion may occur. A dust explosion may occur
when certain finely divided materials are mixed with air
(oxygen) and then are ignited by, for example, a spark.
In order to minimise the risk of dust explosions, all in-
cluded parts of the conveying system must be connect-
ed to one and the same point of earth (equipotential)
according to applicable regulations. It is also important
not to smoke, weld or carry out other work where the
risk of generation of sparks may be present in the vi-
cinity of the conveyor.
In the table below are some examples of materials that
may cause dust explosions.
The conveyor may not be used in explosive surround-
ings containing the following gases: acetylene, carbon
disulphide, hydrogen, hydrogen sulphide and ethylene
oxide.
ATEX-Atmosphere Explosible and CE.
PIAB vacuum conveyors are not EX classified.
PIAB vacuum conveyors conforms to EU directive 94/
9/EC.
Cleaning of filters
It is important to check and clean/change filters at reg-
ular intervals so that they are not clogged, as this
might lead to the fact that the filters will be subjected
to overload, and that undesired matters or particles
leak from the conveyor.
Emergency stop
The system builder shall provide the machine with an
emergency stop function. As an option to the vacuum
conveyor there is a remote control box with a built-in
emergency stop function.
Start/stop of the conveyor
The conveyor is started either with the provided control
unit or via another main control system. The conveyor
stops if the supply of compressed air is suddenly inter-
rupted. The conveyor must be re-started by the opera-
tor even if the supply of compressed air is reactivated.
Vacuum power at the inlet
Careless usage and incorrect installation of the feed-
ing point of the vacuum system may cause injuries.
The vacuum level is concentrated at the feeding point
and may cause injuries to eyes and mucous mem-
branes.
X
Never aim a suction tube, a feed nozzle or a hose
at anyone.
X
The larger the suction inlet, the higher the power
and danger.
X
The installation must be made so that the inlet
cannot contact the operator and other people.
X
Always remember to disconnect the supply of
compressed air when cleaning or servicing the
vacuum conveyor.
