5.3 Operating conditions
5.3.1 Temperature ranges
Ambient temperature: 0 °C … +60 °C
Medium temperature: -10 °C … +140 °C
Permitted medium temperature depending on diaphragm material:

remark
EPDM -10 ... +130 °C Steam sterilization up to 140 °C
PTFE / EPDM -10 ... +130 °C Steam sterilization up to 140 °C

1) The specified medium temperature applies only to media which does not
attack diaphragm materials. The behavior of the medium with respect to the
diaphragm may be changed by the temperature of the medium.
The functional characteristics, in particular the service life of the diaphragm,
may be impaired as the temperature of the medium rises.
