Outdoor unit type
The master unit will choose the closest one to the 1st branch pipe.
Note:
1. When connecting the gather pipe and the outdoor, please pay attention to the outdoor pipe dimension.
2. When adjusting the diameter among gather pipes and among the units, please must execute at the branch pipe
side.
3. Please install the gather pipe(gas/liqiud side) in horizontal or vertical direction.
4. When welding with hard solder, please must blow nitrogen. If not, a number of oxide will be produced and cause
heavy damage.Besides,to prevent water and dust into the pipe, please make the brim as outer roll.
