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 10m 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 0.5m 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.
