REFRIGERANT PIPING LENGTH LIMI TAT I ONS
Liquid 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 and
outdoor units.
See Table below for liquid line sizing and maximum lengths :

REFRIGERANT CHARGE ADJ USTMENTS

(Factory ch a r ge for l ineset = 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.(266.16 g). When using other length
or diameter liquid 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
