GENERAL SAFETY WARNINGS
WARNING!
The “K” series of side channel compressors-vacuum pumps
in an “MOR” format are designed and built for use in
industrial plants are fitted with three-phase or single-phase
electric motors of an asynchronous bipolar type, in
compliance with IEC 34-1.
Any use other than the intended use of the
unit may cause serious injury and even
death!
•
The unit may only be started:
In conformity with the use, transport, and handling
purposes indicated in “INTENDED USE”.
According to the values indicated in the
“CHARACTERISTIC DATA” table on page 3.
•
All transportation, assembly, installation, starting up, and
maintenance operations are only to be carried out by
qualified personnel, that is, personnel whose training,
instruction, experience, knowledge of standards,
regulations, accident prevention procedures, and
operating and service conditions, makes them capable of
carrying out all the works necessary, while being aware of
and avoiding any possible danger and/or damage.
When the unit us working there is a danger of
injury due to shearing, crushing,
entanglement, and burns!
Transportation, assembly, installation, starting up, and
maintenance operations are to be carried out wearing
adequate
personal protective clothing
(protective gloves
and safety glasses, safety shoes, and a hardhat).
Do not wear loose-fitting garments, long laces, or other
items that may get entangled in the machine.
Long hair must be gathered up.
Electrical danger!
Inappropriate behaviour may result in serious injury and
even death!
Work on electrical equipment (installation and maintenance)
is only to be done by qualified, authorised electricians!
Before starting to work on the unit or plant, the following
precautions must be taken:
Switch off the mains power supply.
Adopt measures to prevent it being switched on again.
Only open the terminal box after checking that the power is
off altogether!
Danger due to rotating components (cooling
fan for the electric motor, impeller, and
shaft): Cutting or shearing of limbs,
entanglement or trapping of hair or clothing.
Danger due to excess pressure and vacuum:
Sudden ejection of process gases (injury to
the skin and eyes), and sudden sucking in of
hair and clothing!
Danger due to process gases that come out
and cause burns!
•
The unit may only be started and operated under the
following conditions:
The unit must be fully assembled and whole (not
damaged).
Piping must be connected to the silencers using fixings,
connections, pipes, pipe fittings, and tanks that are
watertight and sufficiently strong to withstand the
pressures that develop.
Connections to the suction and delivery silencers must
not be closed, clogged, or dirty.
Regularly check that the seatings for fixings, connections,
piping, pipe fittings, and tanks are firmly secured!
•
Before starting maintenance work on the unit, the
following safety precautions must be taken:
Put the unit out of order and ensure that it cannot be
switched on again.
Put a sign on the plant’s controls and on the control units
that reads: “DANGER! Maintenance work on the
compressor-vacuum pump in progress! Do not switch
on!”
Wait until the unit has stopped completely, that is, until
the impeller has stopped rotating.
Allow the unit to cool down!
Make sure that there is no pressure or vacuum in the unit
or in the piping to be disconnected.
Make sure that no fluid can flow out of the unit and/or
plant!
Danger due to rotating impeller: Cutting or
shearing of limbs!
The impeller can be accessed while it is rotating by opening
the suction and delivery silencers!
Never put your hands or any item into these openings.
Fit the suction and/or delivery silencers with additional
silencers or additional pipes sufficiently long to prevent
access to the impeller.
