WARNING

Make sure to properly lubricate the bearings. Failure to do so may result in ex-
cess heat generation, sparks, and / or premature failure.

CAUTION

The mechanical seal used in an ATEX classified environment must be proper-
ly certified. Prior to start up, ensure all points of potential leakage of process
fluid to the work environment are closed.

CAUTION

Never operate the pump without liquid supplied to mechanical seal. Running a
mechanical seal dry, even for a few seconds, can cause seal damage and
must be avoided. Physical injury can occur if mechanical seal fails.

WARNING

Never attempt to replace packing until the driver is properly locked out and the
coupling spacer is removed.

WARNING

Dynamic seals are not allowed in an ATEX classified environment.

WARNING

DO NOT operate pump below minimum rated flows or with suction and/or dis-
charge valve closed. These conditions may create an explosive hazard due to
vaporization of pumpage and can quickly lead to pump failure and physical in-
jury

WARNING

Ensure pump is isolated from system and pressure is relieved before disas-
sembling pump, removing plugs, opening vent or drain valves, or disconnect-
ing piping.

WARNING

Shutdown, Disassembly, and Reassembly:

Pump components can be heavy. Proper methods of lifting must be employed
to avoid physical injury and/or equipment damage. Steel toed shoes must be
worn at all times.

WARNING

The pump may handle hazardous and/or toxic fluids. Observe proper decon-
tamination procedures. Proper personal protective equipment should be worn.
Precautions must be taken to prevent physical injury. Pumpage must be han-
dled and disposed of in conformance with applicable environmental regula-
tions.

WARNING

Operator must be aware of pumpage and safety precautions to prevent physi-
cal injury.

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.
