When planning a layout for Units A, B and C, comply with the following:
1. The lengths after branching ("a" and "b", "b" and "c", "a" and "c") should be equal if feasible.
Install Units A, B and C so that the difference of the branching lengths becomes less than 10m if the
lengths cannot be equal due to the branch pipe position.
2. Install Units A, B and C on the same level.
If Units A, B and C cannot be installed on the same level, the difference in level should be limited to 0.5 m
or less.
3. Be certain to install Units A and B and C in the same room.
Units A, B and C cannot be operated independently each other.
