2.1European Union 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 before disposing of equipment, as well as during service and maintenance.

Refer to the full regulation for additional details.

2.2Connection Sizes

The copper pipe connections on the Liebert XDP are:

Building Chilled Water Supply	2-5/8" OD
Building Chilled Water Return	2-5/8" OD
Refrigerant Supply	1-1/8" OD
Refrigerant Return	2-1/8" OD

2.2.1Recommended Pipe Size

Connect the main pipes between the Liebert XDP and the Liebert XD cooling modules according to site specific documentation and the configuration guide for the Liebert XD system.

Elbows and restrictions must be minimized to get good fluid flow.
