The factory charge for 3/8 lineset 9 oz. When using other length or diameterliquid lines, charge adjustments are required per the chart :[(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.}

8 What charge adjustment is required?Formula:(.27 oz/ft x 15ft) (9 oz) = ( ) result is to remove 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 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_Fto80_F ( to ),and outdoor temperature must be 70_F to 100_F ( to ). If outside these conditions, adjust charge for long line sets by LINE APPLICATIONSAn application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptablerefrigerant management for systems reliability.

9 See Accessory Usage Guideline table for required accessories. Defining a system as long linedepends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor Air Conditioner systems, the chart below shows when an application is considered Long with PuronrRefrigerant Long Line Description ft (m) Beyond these lengths, a TXV is requiredTotal LengthOutdoor Unit Above or Below Indoor UnitTXV required beyond 50 ft.
