Eppendorf CO2 Backup System

- Clean with damp rag if necessary.

A qualified service engineer should inspect the CO2 transfer lines from the gas bottles to the solenoid valve annually.

The CO2 Back-up System runs on a rechargeable battery during a power failure.

Contact a qualified service engineer to replace the battery every 5 years or when the Low Battery Alarm sounds despite it being plugged into the mains.
