Fig. 4 Terminal box positions Ambient temperature Ambient temperature: Maximum +104 °F. If the ambient temperature exceeds +104 °F or if the motor is located 3280 feet above sea level or higher, the motor output (P2) must be reduced due to the low cooling effect of the air. In such cases, it may be necessary to use a motor with a higher output. Fig. 5 Relationship between motor output (P2) and ambient temperature Viscosity The pumping of liquids with densities...
