☞
Do not use the pump to generate pressure.
☞
The pumps are designed for ambient temperatures
during operation between +50°F and +104°F (+10°C
and +40°C). Periodically check maximum tempera-
tures if installing the pump in a cabinet or a housing.
Make sure ventilation is adequate to maintain recom-
mended operating temperature. Install an external au-
tomatic ventilation system if necessary. If pumping hot
process gases, make sure that the maximum permitted
gas inlet temperature is not exceeded. The maximum
permitted gas inlet temperature depends on several
parameters like inlet pressure and ambient tempera-
ture (see “Technical data”, pg. 26).
☞
Particles and dust must not enter the pump.
☞
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, measurement, and control of vacuum in vessels de-
signed for that purpose. Any other use will automatically
invalidate all warranty and liability 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 Europe-
an 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.
