9. PRODUCT MODELS AND MAIN SPECIFICATIONS
9-1 Models and Main Specifications.
Note:
*1. The figures for the outside unit models show values measured at a distance of 1 m in the front and a height of 1.5 m.
Values measured with the models actually installed are usually larger than the values shown as a result of ambient noise and reflections.
*2. When the connected piping length is shorter than 50 m, piping size can be decreased piping size to one grade.
*3. Values are subject to change without notice for product improvements.
*4. When the outdoor temperature is low, the temperature reading may be below the target evaporating temperature set for the protection of the unit.
