common condenser supply/return line can be used.
If the total tonnage needed is greater than 300
tons or 900 gpm, the flow from these common lines
can be split between two arrays of chillers. Array
water line sizing is based on a 3 gpm ton condenser
flow and a velocity limitation of 10 feet per second.
Figure 15 - Array Piping shows examples of
acceptable array piping configurations. For help
with determining the most effective array
configuration for your application, please contact
the factory.

* With split header array piping, the limitation of 10 units is
based on the controller capability, not the flow velocity limit
of 10fps.
