Eppendorf Eppendorf CO2 Backup System

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.

All electrical cables should be checked every month. Failure to do so may result in failure of the device. If damage is found, do not attempt to repair by yourself.

1. Turn off CO 2 Back-up System and unplug the power cord from the mains.

2. Inspect the power cord, door switch cable, solenoid cable, and temperature sensor cable for cuts or other damage.

3. If damage is found, contact a qualifed service engineer to replace the damaged parts.

- Check for cuts or abrasions on all electrical wires.

- Inspect all hoses for cuts, chaffing, and squashing.

- Inspect hose connection to bottle and seal connection on the bottle. There should be no damage or corrosion.

- Inspect manifold plugs and seals. There should be no mechanical damage or corrosion.

- Inspect CO2 supply connection and solenoid valve connection. There should be no damage or corrosion.

- Clean with damp rag if necessary.

- Weigh CO2 supplies to see if they are full.

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