0.3 Thermal Hazards
1
Hot surfaces, risk of suffering burns.
Under certain ambient conditions the pump may attain temperatures
over 80° C. There then exists the risk of suffering burns. Note the dan-
ger symbols on the pump and in the case of a hot pump wear the
required protection equipment.
If there is the risk of touching hot surfaces inadvertently, install corre-
sponding protection. When working on a pump which is still warm
from operation, always wear protective gloves.
2
The pump must only be operated at ambient temperatures between
12 and 40 °C. It needs to be ensured that the thermal radiation pro-
duced by the pump can be dissipated sufficiently. If the pump has to
be operated at higher ambient temperatures than 40 °C for any rea-
son, reduced max. differential pressures apply (derating). Please con-
sult Leybold for further details.
3
Operating the pump with less than the specified amount of cooling
water will result in excessively high surface temperatures which can
damage the pump. Moreover, there exists the risk of suffering burns.
4
Before disassembling the cooling water lines, let the pump cool down
first and shut off the supply line.
5
Before any servicing and maintenance work always let the pump cool
down first.
6
Note the warning information on the housing surface. If these warning
notices have been removed, are covered or obstructed, include corre-
sponding additional warning information.
0.4 Hazards Caused by Materials and Substances
1
The vacuum line must be leaktight. Hazardous process gases may
escape or the pumped gases can react with air or atmospheric humid-
ity. After installation of the pump and after servicing work on the vacu-
um system, a leak test will always be necessary.
When pumping hazardous gases we recommend a leak test on a reg-
ular basis. Leaks in the pump cannot be ruled out under all circum-
stances. When pumping hazardous gases, the operator must ensure
that leaks at the pump will not be a hazard.
2
Since not all application related hazards for vacuum systems can be
described in detail in these Operating Instructions, Leybold has availa-
ble a separate document (Safety Booklet) in which the hazards and
general safety concepts for design, operation and maintenance of vac-
uum systems are explained.
When planning to pump hazardous substances with this pump, read
the related chapters in the Safety Booklet and in these Operating
Instructions first. You can download the Safety Booklet from our
homepage.
