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 before disposing of equipment, as well as during service and maintenance.
Refer to the full regulation for additional details.
1.2 Generic Piping Layouts
Liebert XD systems are available in two configurations—differentiated essentially by the method of heat
rejection (see Figure 1.1 below andFigure 1.2 below). The Liebert XDP is a pumping unit connected to a
building chilled water system to control and circulate the refrigerant. Liebert XDPs pump refrigerant to
Liebert XDCF, Liebert XDH, Liebert XDO, Liebert XDR or Liebert XDV modules, isolate refrigerant circuit
from building chilled water supply with an internal heat exchanger and maintains refrigerant temperature
above the actual dew point. The Liebert XDC incorporates the pumping functions with the chiller, which
must be connected to a separate heat rejection system. Pumping and refrigerant control are performed
by Liebert XDC.
