SAFETY PRECAUTIONS
CAUTION
Despite of all the precautions adopted when de-
signing the equipment, there are some risk ele-
ments that arise during operation and servicing.
WARNING!
The temperature of the pump surfaces may ex-
ceed 80 °C.
Install the pump in a protected area accessible on-
ly by authorized personnel, to prevent possible
personal injures due to contact with hot surfaces.
The pump can be placed inside other machines by
adopting the necessary safeguards.
Before carrying out any maintenance on the pump,
be sure the pump is cold.
WARNING!
The discharged air contains part of traces of oil
mist. Check the compatibility with the environment.
A failure of the seal wear can cause an oil leak-
age. Avoid the dispersion to the ground and the
pollution of other materials. In case that any air
containing dangerous substances must be
pumped down (for example biological or microbi-
ological agents), make sure to adopt filtering sys-
tems before introducing air in the work
environment.
Used discharged oil from the pump must be dis-
posed in accordance with the regulations in force
in the Country of use.
WARNING!
Avoid any contact with the pump inlet port during
the pump operation. Introduce air through the inlet
port before every operation cycle.
Any contact with parts under vacuum can cause
injuries.
WARNING!
The pump tank is pressurized. Do not open the oil
filling and discharge plugs during operation.
WARNING!
All maintenance operations must be carried out
with the pump idle, disconnected from the electri-
cal supply, make sure to cold and vented to at-
mospheric pressure. Prevent unexpected start-up
(e.g. block the power switch with a lock).
WARNING!
Some components of the electrical equipment are
electrically charged during operation. Any contact
may cause serious injuries to persons or objects.
Connections and controls of the electrical system
must be carried out by skilled personnel only.
The electrical equipment must comply with the EN
60204-1 standard and with any other laws in force
in the Country of use.
Besides, electrical equipment must comply with
EN 61000-6-4 and EN 61000-6-2 standards con-
cerning electromagnetic compatibility and electro-
magnetic immunity for industrial environment.
WARNING!
The use of the pump in situations unforeseen or
not recommended by this manual, as well as lack
of correct maintenance, may create high risks for
overheating or fire.
In case of a fire do not use water to extinguish, but
use a powder CO
2
extinguisher or other means
compatible with the electric equipment and lubri-
cating oil.
TRANSPORT AND HANDLING
Lifting
The orientation of the packed components must
correspond to the instructions given by the picto-
grams on the external covering of the packaging.
For loading and unloading, use lifting equipment
suitable for the pump weight. Use the suitable lift-
ing eyebolts to lift the pump (see figure below).
