The factory charge for 3/8” lineset 9 oz. When using other length ordiameter liquid lines, charge adjustments are required per the chart above.Charging Formula:[(Lineset oz/ft x total length) – (factory charge for lineset)] charge adjustmentExample 1: System has 15 ft of line set* using existing 1/4“ liquid line. What charge adjustment is required?Formula:(.27 oz/ft x 15ft) – (9 oz) (-4.95) oz.Net result is to remove 4.95 oz of refrigerant from the systemExample 2: System has 45 ft of existing 5/16” liquid line. What is the charge adjustment?Formula:(.40 oz/ft. x 45ft) – (9 oz.) 9 oz.Net result is to add 9 oz of refrigerant to the systemNOTE: Conditions must be favorable for charging by subcooling method. Indoor temperatures must be 70 F to 80 F (21.1 C to 26.7 C),and outdoor temperature must be 70 F to 100 F (21.2 C to 37.8 C). If outside these conditions, adjust charge for long line sets byweigh in method.* When applicable. Refer to Physical Data Table in this Specification and to the Installation Instructions for more information.LONG LINE APPLICATIONSAn application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintainacceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining asystem as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor andoutdoor units.For Air Conditioner systems, the charts below shows when an application requires a TXV and long line accessories due to linesetlength.AC with R 410A Refrigerant Long Line Description ft (m) Beyond these lengths, a TXV is requiredOutdoor Unit Above or Below Indoor UnitTXV required beyond 20 ft.
