(4) Setting of the multi-kit pipe

●

It is necessary to use optional multi-kit to prevent unit’s insufficient capacity due to the uneven distribution of

the refrigerant. Do not use connectors to connect.

1) The installation of the main branch as shown below

‧〝

〞：

Main Pipe (The pipe between each multi-kit or the pipe between the outdoor units and the first multi-kit)

‧

Main Branch

：

One multi-kit is connected with other multi-kits connected with more than one indoor unit.

‧

Setting Condition

：

The branches extending to third are allowed, but main branches can only extend to second.

Piping length within 40 m between the first branch and the indoor units

Piping length in excess of 40 m between the first branch and the indoor units

‧

Only one main branch is allowed, and total indoor unit capacity should be in the range of 40% to 60% for each

route after the first main branch.
