INSTALLATION
Interconnecting Tubing (cont�)
Example: A 3-Ton heat pump unit is installed 50'
below the ID unit, requires a 75' of 1/2" diameter
liquid line, and 4 90° LR elbows�
• Fitting Equivalent Length (ft.) = 4 x .9 = 3.6'
• Total Equivalent Length (ft.) = 75' + 3.6' = 78.6'
• Rounded-down value (ft.) = 75'

Long Line Set Applications
Long line set applications are defined as applica-
tions that require accessories or alternate construc-
tion methods� The following are special consider-
ations that need to be addressed when installing a
long line set application:
• Additional refrigerant charge
• Fitting losses and maximum equivalent length
considerations
• Refrigerant migration during the off cycle
• Oil return to the compressor
• Capacity losses
• System oil level adjustment
Table 2 is used to determine if the application is
considered to have a long line set� The region of
the chart that is shaded grey is considered to be
a long line set application.
Oil Level Adjustments for Long
Line Set Applications
Additional oil will need to be added for long line set
applications� (Ref� Table 2)� Below is the equation for
the oil level adjustment and the compressor name
plate oil charge for the different od units.
Oil to be Added = [(Charge Adjustment + OD
Unit Name Plate Charge (oz.)) x (0.022) – [(0.10) x
(Compressor Name Plate Oil Charge (oz.))]
Example: An application requires 125ft of line set
with a liquid line diameter of 3/8", Charge Adjust-
ment = 52.4 oz., Name Plate Charge = 107 oz.,
Name Plate Oil Charge = 25 oz., Oil to be Added =
((52.4 oz. +107 oz.) x .022) – (.10 x 25 oz.) = 1.0 oz.

This application is acceptable because the 50'
vertical rise is less than the maximum rise of 75' for
this application� The application is also considered
to have a long line set� Reference the long line set
section of the I&O for detail�
