3/8
5/16
1/4

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
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

LONG LINE APPLICATIONS
An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain
acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a
system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and
outdoor units.
For Air Conditioner systems, the charts below shows when an application requires a TXV and long line accessories due to lineset
length.
AC with R−410A Refrigerant Long Line Description ft (m) Beyond these lengths, a TXV is required

} Sensible capacities shown are based on 80_F (27_C) entering air at the indoor coil. For sensible capacities at other than 80_F (27_C), deduct 835 Btuh (245 kW) per 1000 CFM (480 L/S) of
indoor coil air for each degree below 80_F (27_C), or add 835 Btuh
(245 kW) per 1000 CFM (480 L/S) of indoor coil air per degree above 80_F (27_C).
# Expanded cooling capacities are based on indoor and outdoor unit at the same elevation per AHRI standard 210/240-2008. If additional tubing length and/or indoor unit is located above
outdoor unit, a slight variation in capacity may occur.
** System kw is total of indoor and outdoor unit kilowatts.
{{ At TVA rating indoor condition (75_F edb/63_F ewb). All other indoor air temperatures are at 80_F edb.
NOTE: When the required data falls between the published data, interpolation may be performed. Extrapolation is not an acceptable practice.
