Lubricate the motor bearings to the manufacturer's recommendations.
Lubrication recommendations are included with the packet attached to the fan.
Should this packet be missing, the following will apply:
Integral Horsepower Ball Bearings Motors: Motors having pipe plugs or
grease fittings should be re-lubricated while warm and at standstill. Replace
one (1) pipe plug on each end shield with a grease fitting. Remove the other
plug for grease relief. On low pressure, grease, run, and lubricate until the new
grease appears at the grease relief. Allow the motor to run for ten (10) minutes
to expel any excess grease. Replace the pipe plugs. Motors not having pipe
plugs or grease fittings can be re-lubricated by removing the end shield, clean-
ing the grease cavity, and refilling three-fourths or circumference of the cavity.
