The Liebert XD system components require little maintenance when proper fluid levels are
maintained and proper startup and operation procedures are followed. The following tasks should be
performed at the intervals stated:
1. Clean or replace chilled water strainer annually. Adjust accordingly based on purity of chilled
water.
2. Check sight glass level of receiver every 4-6 weeks. During normal operation, the level should be
at or above the second sight glass.
3. Check system for leaks every 4-6 weeks.
8.1 Fluorinated Greenhouse Gas Requirements
Stationary air conditioning, refrigeration, heat pump equipment and stationary fire protection
systems 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
atmosphere.
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.
