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.
HARMFUL SUBSTANCES EMISSIONS
The discharged air contains part of traces of oil mist.
Check the compatibility with the environment.
Make sure a correct air change is allowed otherwise convey the pump discharge outside.
A failure or the seals wear can cause an oil leakage.
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 microbiological agents), make sure to adopt filtering systems before introducing air
in the work environment.
Used discharged oil from the pump must be disposed in accordance with the regulations
in force in the Country of use.
Do not dispose into the environment.
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.
HAZARD CAUSED BY PRESSURE
The pump tank is pressurized. Do not open the oil filling and discharge plugs during
operation.
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).
