Comply with all notes on correct vacuum and electri-
cal connections; see section „Use and operation“, pg.
33.
+
Do not use the pump to generate pressure.
+
The pumps are designed for ambient temperatures
during operation b50°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. 24).
+
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 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 (pumps with AC motor) must be plugged into an
outlet that is properly grounded. Provide a slow blow
fuse according to the electrical supply (see „Techni-
cal data“, pg. 24). Failure to connect the motor to
ground may result in deadly electrical shock.
