Maintenance

9.0MAINTENANCE

Minimal maintenance is required to keep the Liebert XDR operating at optimal levels. The module should be cleaned and checked for damage. Suggested maintenance includes:

•Cooling fins—Clean any dust and debris from the cooling fins, taking care not to bend them.

9.1Fluorinated Greenhouse Gas Requirements

Stationary air conditioning, refrigeration, heat pump equipment and stationary fire protection sys- tems in the European Community market and operating with fluorinated greenhouse gases (f-gas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F-gas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the atmo- sphere.

The F-Gas Regulation requires operators to use all measures that are technically feasible and do not entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to recover f-gas during equipment service and maintenance and before disposing of equipment.

Refer to the full regulation for additional details.
