Protect Against Dirt & Chemicals - A.O. Smith ST1302 Manual

24
Level 2
Locate motor on a slight elevation so water
will not run or puddle nearby.
Avoid spilling or dripping liquid chemicals on
or near the motor.
Avoid splashing water on or near the motor.
Repair leaky pipe joints, "O" rings, or pump
seals promptly.
Avoid locating motor in highest humidity
area.
If the motor is flooded, the bearings may be
ruined. Once they start making noise, failure is
imminent.
If the seal leaks and is not replaced, the bear-
ings may also be ruined. A new seal should be
installed any time a motor is replaced. A slinger
or flinger should also be used on the motor shaft
to deflect water from the bearing location.
PROTECT AGAINST DIRT & CHEMICALS
Avoid sweeping or stirring dust near the
motor while it is running.
Chemicals should not be stored near the
motor. Chlorine can be especially damaging
if in a liquid form being dispensed into a
filter pit.
