C or 104 а F, unless the motor has been specially designed or otherwise cleared for use in a higher ambient temperature. A. Mounting Locate the motor in a place that is clean and well ventilated. The motor enclosure is designed such that dripping, wind blown and splashing water will not damage the motor. Under conditions of extreme weather and moisture, additional protection, such as a pump house, is recommended; however, the free flow of air around the motor must not be obstructed. The ambient air temperature should not exceed 40 The motor should be lifted by the lugs provided. These lugs...

Table 2 , Oil Viscosity. Operation in ambient temperatures that are near or below freezing may require preheating the oil or the use of a special oil. Too heavy an oil could cause the following: a. Increased fluid friction losses resulting in higher operating temperatures. Higher temperatures will cause the oil to oxidize or break down at an accelerated rate. b. A heavy oil tends to churn or foam more than a lighter weight oil. c. Bearings may run warmer because of reduced oil circulation through and around the bearings. Too light an oil may allow the oil film to wipe or break down. For...
