Operating Instructions Raman Rxn2
34 Endress+Hauser
7.4.6 Air filter
The Raman Rxn2 incorporates a tacked polyester spun air filter element to reduce dust intake into the base unit. The
air filter is accessed by a magnetically secured access panel on the front of the instrument. The air filter should be
cleaned with compressed air once every month or if the embedded software is reporting an internal
over-temperature error (if ambient temperature is within specification). In extremely dusty conditions, the air filter
should be cleaned more often. The air filter has a blue tacky side which should be oriented toward the outside of the
base unit.
If a replacement air filter (p/n 70207492) is needed, refer to our website (https://endress.com/contact) for the list
of local sales channels in your area.
