AAON CC-063 - Manual (Page 21)

21
Note: CC-006, CC-007, CC-008, and CC-
010 HGB line sizes are based on four stage
cooling operation condensing units, with
two step compressors. CC-031, CC-034,
CC-040, CC-045, CC-050, CC-055, and
CC-063 HGB line sizes are based on four
stage cooling operation condensing units,
with tandem compressors. With HGB, four
stage cooling is recommended on these sizes
of units.
Two stage cooling operation condensing
units in these sizes with HGB may need
larger HGB line sizes.
Figure 3 - Riser Height Versus Total Equivalent Line Length
Note: Figure 3 is for R-410A split system applications with CC-002 through CC-063 units. The
region of acceptable riser height is the light area. Select the corresponding predetermined line
size from the table above. Refer to AAON ECat32 for application specific refrigerant line sizing
recommendations.
Total Equivalent Line Length in this
figure is limited to 100 equivalent
feet.
