Important Safety Information
0.1 Mechanical Hazards
1
Avoid exposing any part of the human body to the vacuum.
2
Even during standstill of the RUVAC it is dangerous to grasp into the
pump casing. Fingers can easily be squeezed between impellers due
to the high inertia of the parts. Please use caution when grasping into
the pump and make sure that the pump is secured against unwanted
rotation due to differential pressures.
3
The crane eyes of the RUVAC pumps must not be used to lift any
pump combinations (Roots + backing pump). Exceptions are allowed
only with approval from Leybold. Secure the pump by the crane at the
intended eyes until a firm connection has been established with the
backing pump or a corresponding suspension has been installed.
4
Do not operate the pump with any of the covers removed. Serious
injury may result.
5
Never operate the RUVAC without connected intake line or blank
flange at the intake.
6
Make sure that the gas flow from the discharge port is not blocked or
restricted in any way.
7
It is recommended to always only operate the RUVAC with a suitable
discharge line which is properly connected.
8
If discharged gases must be collected or contained, do not allow the
discharge line to become pressurized.
9
When moving the RUVAC always use the allowed means.
Two crane eyes are provided on this pump as standard.
10
Do not allow the ingestion of any objects (screws, nuts, washers, piec-
es of wire, etc.) through the intake port of the pump. The use of the
intake screen is strongly recommended. In case the pump is operated
without intake screen the operator has to make sure that no objects
can enter the pump through the intake port. Objects falling into the
pump can cause severe damage including leaks to atmosphere.
11
Should malfunctions affect the pump, seized impellers in particular
owing to hard deposits or foreign objects, the occurrence of leaks
affecting the housing cannot be ruled out. When pumping hazardous
gases the operator must ensure that the possibility of such an incident
is excluded, respectively that leaks at the pump casing will not pose a
hazard.
12
In order to prevent the destruction of equipment and injuries to the
operating personnel, we urgently recommend to follow the installation
instructions given in these Operating Instructions.
