Cleaning and decontamination
D A N G E R
Always remove power from the controller before performing maintenance activities.
The analyzer does not normally require any cleaning or decontamination. If needed, clean the
exterior of the instrument with a moist cloth and a mild soap solution. Never use cleaning agents
such as turpentine, acetone or similar products to clean the instrument, including the display and any
accessories.
Fuse replacement
Fuses are not user-serviceable items. The need for fuse replacement in controllers indicates severe
technical failure and is therefore considered to be a service activity. If a blown fuse is suspected,
contact Technical Support.
Battery replacement
The lithium ion backup battery is not user replaceable. Contact Technical Support for replacement.
