The factory charge for 3/8” lineset 9 oz. When using other length or diameter liquidlines, 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 temperature must be 70 F to 80 F (21.1 C to 26.7 C), and outdoortemperature must be 70 F to 100 F (21.1 C to 37.8 C). If outside these conditions, adjust charge for long line sets by weigh-in method.* When applicable. Refer to Physical Data Table in this PD 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 maintain acceptable refrigerantmanagement for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on theliquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.For Air Conditioner systems, the chart below shows when an application is considered Long Line.AC with R-410A Refrigerant Long Line Description ft (m) Beyond these lengths, a TXV is requiredTotal LengthTXV required beyond 50 ft.
