WARNING
Lock out driver power to prevent accidental startup and physical injury.
CAUTION
Allow all system and pump components to cool before handling them to pre-
vent physical injury.
CAUTION
If pump is a Model NM3171, NM3196, 3198, 3298, V3298, SP3298, 4150,
4550, or 3107, there may be a risk of static electric discharge from plastic
parts that are not properly grounded. If pumped fluid is non-conductive, pump
should be drained and flushed with a conductive fluid under conditions that
will not allow for a spark to be released to the atmosphere.
WARNING
Never apply heat to remove an impeller. The use of heat may cause an explo-
sion due to trapped fluid, resulting in severe physical injury and property dam-
age.
CAUTION
Wear heavy work gloves when handling impellers as sharp edges may cause
physical injury.
CAUTION
Wear insulated gloves when using a bearing heater. Bearings will get hot and
can cause physical injury.
WARNING
Noise:
Sound pressure levels may exceed 80 dbA in operating process plants. Clear
visual warnings or other indicators should be available to those entering an
area with unsafe noise levels. Personnel should wear appropriate hearing pro-
tection when working on or around any equipment, including pumps. Consider
limiting personnel’s exposure time to noise or, where possible, enclosing
equipment to reduce noise. Local law may provide specific guidance regard-
ing exposure of personnel to noise and when noise exposure reduction is re-
quired.
WARNING
Temperature:
Equipment and piping surfaces may exceed 130ºF (54ºC) in operating proc-
ess plants. Clear visual warnings or other indicators should alert personnel to
surfaces that may reach a potentially unsafe temperature. Do not touch hot
surfaces. Allow pumps operating at a high temperature to cool sufficiently be-
fore performing maintenance. If touching a hot surface cannot be avoided,
personnel should wear appropriate gloves, clothing, and other protective gear
as necessary. Local law may provide specific guidance regarding exposure of
personnel to unsafe temperatures.

ATEX Considerations and Intended Use
Special care must be taken in potentially explosive environments to ensure that the equipment is proper-
ly maintained. This includes but is not limited to:
Description of ATEX
The ATEX directives are a specification enforced in Europe for electrical and non-electrical equipment
installed in Europe. ATEX deals with the control of potentially explosive atmospheres and the standards
of equipment and protective systems used within these atmospheres. The relevance of the ATEX re-
quirements is not limited to Europe. You can apply these guidelines to equipment installed in any poten-
tially explosive atmosphere.
