3. Safety rules
WARNING:
Despite of all the precautions adopted when designing the equipment, there are
some risk elements that arise during operation and servicing.
HOT SURFACES
The temperature of the pump surfaces may exceed 80°C.
Install the pump in a protected area accessible only 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.
HAZARD CAUSED BY VACUUM
Any contact with parts under vacuum can cause injuries.
Avoid any contact with the pump inlet port during the pump operation. Introduce air in
the inlet circuit before every operation cycle.
FOR A SAFE MAINTENANCE
All maintenance operations must be carried out with the pump idle, disconnected from
the electrical supply, with the pump cold, vented to atmospheric pressure. Prevent
unexpected start-up (e.g. block the power switch with a personal lock).
ELECTRIC SAFETY
Some components of the electric equipment are electrically charged during operation.
Any contact may cause serious injuries to persons or objects.
Connection and control of the electric system must be carried out by skilled personnel
only.
The electrical equipment must comply with the EN 60204-1 standard and with any other
law in force in the Country of use.
Besides, electrical equipment must comply with EN 61000-6-4 and EN 61000-6-2
standards concerning electromagnetic compatibility and electromagnetic immunity
for industrial environment.
FIRE HAZARD
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
