Maximum recommended total equivalent pipe length is 150 ft (46m). Suction and liquid lines may require additional specialty items when vertical lines
exceed 20 ft. (6m) and/or condensing unit installation is more than 15 ft. (4.6m) below the evaporator. Contact Vertiv™ Application Engineering for
assistance.

All evaporator units and condensing units are fully factory-charged with refrigerant. If field-supplied refrigerant piping is installed, refrigerant must be
added; refer to Table 7.10 below to determine the additional charge.
