AINTENANCE
The Liebert XD system components require little maintenance when proper fluid levels are main-
tained and proper startup and operation procedures are followed. The following tasks should be per-
formed at the intervals stated:
1. Check sight glass level of receiver on all circuits every 4-6 weeks. During normal operation, the
level should be at or above the first sight glass.
2. Check system for leaks every 4-6 weeks
8.1 Fluorinated Greenhouse Gas Requirements
Stationary air conditioning, refrigeration, heat pump equipments 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 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.
8.2 Air Cooled Condenser
Restricted airflow through the condenser coil will reduce the operating efficiency of the unit and can
result in high compressor head pressure and loss of cooling.
Clean the condenser coil of all debris that will inhibit air flow. This can be done with compressed air
or commercial coil cleaner. Check for bent or damaged coil fins and repair as necessary. In winter, do
not permit snow to accumulate around the sides or underneath the condenser.
Check all refrigerant lines and capillaries for vibration isolation. Support as necessary. Visually
inspect all refrigerant lines for signs of oil leaks.
