10.0 MAINTENANCE
Minimal maintenance is required to keep the Liebert XDV operating at optimal levels. The unit
should be cleaned and checked for damage and worn parts. Suggested maintenance includes:
• Cooling fins—Clean any dust and debris from the cooling fins, taking care not to bend them
• Circulating fans—Clean any dust from the fans.

10.1 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.

10.2 Internal Access

The conditions required for sensitive electronic equipment should preclude the accumulation of appre-
ciable amounts of dust in the Liebert XDV. Most of that small amount should be found on the rear
coils, near the air inlet. The rear covers and the fan tray on the front of the Liebert XDV are easily
removed for maintenance. (A wiring diagram is provided on the inside of the fan tray.)
To remove the rear grille:
1. Loosen the six screws holding the grille on the rear of the Liebert XDV.
2. Remove the grille and lay it as ide for reinstallation.

WARNING
Risk of high-speed moving parts. Can cause death, injury and equipment damage.
Before opening the Liebert XDV, shut the unit off and disconnect all electrical power. Wait for
the Liebert XDV’s fans to stop rotating before beginning to open the unit.
!
WARNING
Risk of electrical shock. May cause death or injury.
Disconnect all power before working within.
• Turn off the main switch (in the center of the fan tray).
• Remove both power cords from the electrical supply outlets or from the receptacles on the
back of the Liebert XDV.
