- Ambient Temperature
Max. Ambient temperature:+40°C.Ambient temperature above40°C,or
installation at altitude of more than 1000 m above sea level, require the
use of an oversize motor. Because of low air density and poor cooling
effects, the motor output power P2 will be decreased. See the picture.
For example, when the pump is installed at altitude of more than 3500 m
above sea level，P2 will be decrease to 88%.when the ambient
temperature is 70°C，P2 will be decreased to 78%.
