* Units are rated with 25 ft (7.6 m) of lineset length. See Vapor Line Sizing and Cooling Capacity Loss table when using other sizes and lengths of
lineset. Note: See unit Installation Instruction for proper installation.

Check the piston size shipped with the indoor unit to see if it matches the required indoor piston size. If it does not match,
replace the indoor piston with the correct size per the table below.

REFRIGERANT CHARGE ADJUSTMENTS

Liquid Line Size R- 410A Charge oz/ft
0.60
3/8
(Factory charge for lineset = 9 oz)
5/16 0.40
1/4 0.27

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.

Total sensible capacities are based on net capacities. Blower heat has been subtracted.
Sensible capacities shown are based on 800 F (270 C) entering air at the indoor coil. For sensible capacities at other than 800 F (270 C), deduct 835 Btuh (245
kW) per 1000 CFM (480 L/S) of indoor coil air for each degree below 800 F (270 C), or add 835 Btuh 245 kW) per 1000 CFM (480 L/S) of indoor coil air per
degree above 800 F (270 C).
Detailed cooling and heating capacities are based on indoor and outdoor unit at the same elevation per AHRI standard 210/240 -2008. If additional tubing length
is required 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.
