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.
