Different grease types are generally incompatible
and should not be mixed. Mixing different types
can cause lubricant and bearing failure. Thoroughly
clean bearing and cavity before changing grease
type.
Some motor designs use different bearings on each
motor end. This is normally indicated on the motor
nameplate. In this case, the larger bearing is
installed on the motor’s drive endplate. For best re-
lubrication results, only use the appropriate
amount of grease for each bearing size (not the
same for both).
Do not over lubricate the bearings as the lubricant
will work its way into the motor and can cause
premature motor failure.

Fan Rotor Cleanliness
Once a year, or if vibration develops, clean the fan
rotor surfaces so the unit runs smoothly. To do this,
Lockout- tag out all power sources, remove the
screen. With the fan rotor accessible, clean it with
a suitable cleaner and wipe it with a cloth. If
necessary, scrape it gently with a suitable tool.
Do not strike the rotor to dislodge debris, as this
may cause it to go out of balance, making vibration
worse.
