CAUTION
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 10 m 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.
