PIPE LAYOUT PROCEDURE
Main—The pipe segment between the out-
door unit and the first Y-Branch or Header kit
Branch—A segment of pipe between two
Y-Branches or a Y-Branch and a Header kit
Run-out
—The segment of pipe connecting
an indoor unit to a Y-Branch or Header kit
—Full Port Ball Valve
(Install on both liquid and vapor lines)
