Installation 2.5 Piping Considerations The Liebert Mini-Mate2, Liebert DataMate and the 3-ton Liebert Challenger 3000 split system units are designed with quick-connect fittings and are factory-charged to proper refrigerant levels. This permits connecting units without brazing inside critical spaces. These split systems require two refrigerant lines—an insulated copper suction line and a copper liquid line—between the evaporator and condensing units. The 8-ton Liebert Mini-Mate2 split system

Installation 2.5.2 Pre-Charged Line Sets Liebert pre-charged line sets are available in 15 ft (4.5m) and 30 ft (9m) lengths (see Table 7). NOTICE Risk of improper handling and installation of pre-charged lines. Can cause kinks and similar damage to lines. Care must be taken to prevent kinking the pre-charged lines for 1-ton and 3.5-ton units. Use tube benders and make all bends before making connections to either end of the pre- charged pipes. Coil any excess tubing in a horizontal plane with t
