1. Meets the highest allowable temperature conditions and complies with ASHRAE
(American Society of Heating, Refrigerating and Air-Conditioning Engineers) 2011
Thermal Guidelines Class A2. The maximum value of the ambient temperature
and the altitude is from 35ºC at an altitude of 950m (3000 feet) to 28ºC at an
altitude of 3050m (1000 feet).
The allowable ambient temperature is decreased by 1ºC for every 300m increase
in altitude above 950m.
