Connect Ø15.9 pipe with flaring.
MAP060 type
Ø19.1
For braze connection of Ø19.1 gas pipe, refer to the following method.
1) Form the pipe so that the end part of the pipe will be out from the outdoor unit along the
taking-out direction of the pipe.
The Ø15.9 gas pipe to be supplied locally.
2) Using the joint socket (Accessory), connect with braze Ø15.9 gas pipe and Ø19.1 gas pipe
at outside of the outdoor unit.
3) After connecting the pipes, apply thermal insulation process to the gas pipe until near the
valve.

• Capacity code of indoor and outdoor units
• For the indoor unit, the capacity code is decided at each capacity rank.
• The capacity codes of the outdoor units are decided at each capacity rank.
The maximum No. of connectable indoor unit and the total value of capacity codes of the indoor units are also decided.
