. CZ-P680BH1U
Use: For indoor unit (Capacity after distribution joint is greater than 76,400 BTU/h 22.4kW and no more than 232,000 BTU/h (68.0kW).)*
Note that the dimension marked with every alphabetical letter in the diagram shows the inner diameter.

Insulation
*Insulators for both the Suction tube and the Discharge tube are the same.
*Suction tube and Discharge tube are similar in sizes and both the tube entrances have the same diameter.
So the both Distribution joints can fit into different tubes. Since the diameter of the tube ends for both Suction and Discharge
tube are different, take care not to connect the distribution joint different. See the " # " marks on the above figures.

. CZ-P1350BH1U
Use: For indoor unit (Capacity after distribution joint is greater than 232,000 BTU/h (68.0kW) and no more than 460,700 BTU/h (135.0kW).)*
Example: (B below indicates inner diameter.

* In case the total capacity of indoor units connected after distribution exceeds the total capacity of the outdoor units, select the
distribution tube size for the total capacity of the outdoor units.
