When 1) Total cooling capacity exceed 193,000kBtu or 2) Separate into two branches, use a
separaton tube instead.
* When all indoor unit connected to header is indoor unit of cooling only type, use header for
2pipes.
* When header for 3pipes is used, at least 3 or more of RB unit must be connected in port of
header

Installation
(1) Connecting the connection pipes from the indoor units.
Gas pipe
Outdoor
unit side
Liquid pipe
Outdoor
unit side
Always have at least one
indoor unit connected to
the port furthest (opposite)
the outdoor unit side.
Always have at least one
indoor unit connected to
the port furthest (opposite)
the outdoor unit side.
You can connect the
indoor unit to any branch.
You can connect the
indoor unit to any branch.
Note: Do not connected indoor unit of cooling only type to the position of "1" in header of
3pipes.
(2) Use a pipe cutter to cut at the location that matches the piping size or use expanders as
necessary.
Joint pipe
Connections
Field pipe
Expander
Cut in the center of
the connections
(3) Attach a plugging pipe provided if there is no piping connected at the headers.
