REFRIGERANT 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 :

REFRIGERANT CHARGE ADJUSTMENTSLiquid Line Size Puron Charge oz/ft (g/m)
3/8 0.60 (17.74)(Factory charge for lineset = 9 oz / 266.16 g)
5/16 0.40 (11.83)1/4 0.27 (7.98)
Units are factory charged for 15 ft (4.6 m) of 3/8” liquid line*. The factory charge for 3/8” lineset 9 oz. When using other length or diameterliquid lines, charge adjustments are required per the chart above.
Charging Formula:
[(Lineset oz/ft x total length) – (factory charge for lineset)] = charge adjustment
Example 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 system
Example 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 system
NOTE: 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 outdoor temperature 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--inmethod.* 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 acceptablerefrigerant management for systems reliability. 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 units.
For Air Conditioner systems, the chart below shows when an application is considered Long Line.
