This symbol indicates safety
instructions where non-compliance will involve some
risk to safe operation and personal safety and would
damage the equipment or property.
This symbol indicates “strong magnetic
field” safety instructions where non-compliance would
affect personal safety, pacemakers, instruments, or
stored data sensitive to magnetic fields.
This symbol indicates explosive atmosphere
zone marking according to ATEX. It is used in safety
instructions where non-compliance in the hazardous
area would cause the risk of an explosion.

process.
1.6.2
Personnel qualification and training
All personnel involved in the operation, installation,
inspection and maintenance of the unit must be
qualified to carry out the work involved. If the
personnel in question do not already possess the
necessary knowledge and skill, appropriate training
and instruction must be provided. If required the
operator may commission the manufacturer/supplier
to provide applicable training.
Always coordinate repair activity with operations and
health and safety personnel, and follow all plant
safety requirements and applicable safety and health
laws and regulations.
1.6.3
Safety action
This is a summary of conditions and actions to
prevent injury to personnel and damage to the
environment and to equipment. For products
used in potentially explosive atmospheres
section 1.6.4 also applies.
HIGH MAGNETIC FIELDS
Great care should be taken when assembling/
dismantling magnetic rotors, where fitted, because of
the very high forces which can be created by the
magnets.
Persons with pacemakers and any instrumentation
etc sensitive to magnetic fields should be kept well
away from the magnetic drive unit during
dismantling.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
DRAIN THE PUMP AND ISOLATE PIPEWORK
BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.
FLUOROELASTOMERS (When fitted.)
When a pump has experienced temperatures over
250 ºC (482 ºF), partial decomposition of
fluoroelastomers (example: Viton) will occur. In this
condition these are extremely dangerous and skin
contact must be avoided.
HANDLING COMPONENTS
Many precision parts have sharp corners and the
wearing of appropriate safety gloves and equipment
is required when handling these components. To lift
heavy pieces above 25 kg (55 lb) use a crane
appropriate for the mass and in accordance with
current local regulations.
NEVER OPERATE THE PUMP WITHOUT THE
COUPLING GUARD AND ALL OTHER SAFETY
DEVICES CORRECTLY INSTALLED
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
HOT (and cold) PARTS
