(Note)
When installing the machine at 1,000m or more above sea level, the heat 
dissipation characteristics will drop as the altitude increases. The upper limit of 
the ambient temperature drops 1°C with every 100m increase in altitude. 
(The ambient temperature at an altitude of 2,000m is between 0 and 45°C.)
