+
Comply with all notes on correct vacuum and electri-
cal connections; see section “Use and operation”, pg.
36.
+
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. 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, 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.
