3REFRIGERANT PIPING LENGTH LIMITATIONSLiquid Line Sizing and Maximum Total Equivalent Lengths{ for Cooling Only Systems with Puronr Refrigerant:The maximum allowable length of a residential split system depends on the liquid line diameter and vertical separation between indoor andoutdoor units.See Table below for liquid line sizing and maximum lengths :Maximum Total Equivalent LengthOutdoor Unit BELOW Indoor UnitSize Liquid LineConnectionLiquidLineDiam.w/TXVAC with Puron Refrigerant Maximum Total Equivalent Length{: Outdoor unit BELOW IndoorVertical Separation ft (m)0--- 5(0--- 1.5)6--- 10(1.8--- 3.0)11--- 20(3.4--- 6.1)21--- 30(6.4--- 9.1)31--- 40(9.4--- 12.2)41--- 50(12.5--- 15.2)51--- 60(15.5--- 18.3)61--- 70(18.6--- 21.3)71--- 80(21.6--- 24.4)024AC withPuron3/81/4 75 75 75 50 50 --- --- --- --- --- --- --- ---5/16 250* 250* 250* 250* 250* 225* 175 125 1003/8 250* 250* 250* 250* 250* 250* 250* 250* 250*036AC withPuron3/8 5/16 175 150 150 100 100 100 75 --- --- --- ---3/8 250* 250* 250* 250* 250* 250* 250* 250* 250*048AC withPuron3/8 3/8 250* 250* 250* 250* 250* 250* 230 160 --- ---060AC withPuron3/8 3/8 250* 250* 250* 225* 190 150 110 --- --- --- ---* Maximum actual length not to exceed 200 ft (61 m){ Total equivalent length accounts for losses due to elbows or fitting.

The factory charge for 3/8” lineset 9 oz.(266.16 g). When using other lengthor diameter 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 system24APA7
