*2. 60 m is available depending on the model and installation conditions. Please refer to design tool schematic & `Height Check’ document.

*3. 90 m is available. When the piping length exceeds 40 m, use one size larger liquid pipe starting with the section of piping where 40 m is exceeded and all piping after that point.

In the figure above, if the piping labelled “D” exceeds 40 m (but does not exceed 90 m), increase the size of the liquid piping labelled D, c, and d by one size.

*4. 30 m is available. If the height difference between indoor units exceeds 15 m (but does not exceed 30 m), use one-size larger pipes for indoor unit liquid pipes.
In the figure above, if “h1″ exceeds 15 m, increase the size of the liquid piping labelled by one size i.e. pipe `d’.
