5. Operating conditions
Working pressure
Maximum working pressure 145 psi (10 bar).
Fluid temperature
Maximum fluid temperature +284 °F (140 °C).
Relative humidity
Maximum 95%.
Ambient temperature
Maximum ambient temperature +104 °F (40 °C).
Note:
When motors installed more than 3000 ft (914 m)
above sea level, the rated motor output will fall due to
the low
density and consequent low cooling effect of the air. In
such cases, it may be necessary to use an oversize
motor with a higher output.
