* Ensure that the shortest pipe length complies with the following:
L + b ≥ 5 m
a ≥ b
CAUTION
When planning a layout for Units A and B, comply with the following:
1. The lengths after branching ("a" and "b") should be equal if feasible. Install Units A and B
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 and B on the same level. If Units A and B 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 in the same room. Units A and B cannot be operated
independently each other.
