and +40°C). Periodically check maximum temperatures
if installing the pump in a cabinet or a housing. Make
sure ventilation is adequate to maintain recommended
operating temperature. Install an external automatic
ventilation system if necessary. If pumping hot process
gases, make sure that the maximum permitted gas in-
let temperature is not exceeded. The maximum permit-
ted gas inlet temperature depends on several param-
eters like inlet pressure and ambient temperature (see
”Technical data”, pg. 24).
+
Do not aspirate particles and dust.
+
Do not pump liquids.
• Ensure that the pump is chemically resistant to the
pumped substances prior to operation.
Use the equipment only as intended, that is, for genera-
tion of vacuum in vessels designed for that purpose. Any
other use will automatically invalidate all warranty and li-
ability claims. Remain aware of safety and risks.
Setting up and installing the equipment
➨
Equipment must be connected only to a suitable elec-
trical supply and a suitable ground point. As such,
the plug must be plugged into an outlet that is properly
grounded. Failure to connect the motor to ground may
result in deadly electrical shock.
The supply cable may be fitted with a molded Euro-
pean IEC plug or a plug suitable for your local electrical
supply. The cable contains wires color coded as fol-
lows: green or green and yellow: ground; blue or white:
neutral; brown or black: hot.
+
Due to the high compression ratio, the pump may gen-
erate overpressure at the outlet. Check pressure com-
patibility with system components (e.g., exhaust pipe-
line or exhaust valve) at the outlet.
