1.1 Using This Document

this manual prior to installing, operating, or performing any mainte-
nance on the positioner.
The following instructions are designed to assist in unpacking, installing
and performing maintenance as required on Logix
®
420 positioners.
Separate Flow Control Products User Instructions cover the valve,
actuator, or portions of the system and other accessories. Refer to
the appropriate instructions when this information is needed. In most
cases FLOWSERVE valves, actuators and accessories are designed for
specific applications with regard to medium, pressure and temperature.
For this reason they should not be used in other applications without
first contacting the manufacturer.
To avoid possible injury to personnel or damage to positioner parts,
DANGER and CAUTION notes must be strictly followed. Modifying
this product, substituting non-factory parts or using maintenance
procedures other than outlined could drastically affect performance
and be hazardous to personnel and equipment, and may void existing
warranties.
1.2 Terms Concerning Safety
The safety terms DANGER, CAUTION and NOTE are used in these
instructions to highlight particular dangers and/or to provide additional
information on aspects that may not be readily apparent.

1 CAUTION: Indicates that minor personal injury and/or property
damage can occur if proper precautions are not taken.

not taken.
Compliance with other, not particularly emphasized notes, with regard

product itself) is essential in order to avoid faults, which in themselves
might directly or indirectly cause severe personal injury or property
damage.

cally, personal protective equipment must be used as warranted.

experience, instruction and their knowledge of relevant standards,
specifications, accident prevention regulations and operating condi-
tions, have been authorized by those responsible for the safety of the
plant to perform the necessary work and who can recognize and avoid
possible dangers.
In unpacking, installing and performing maintenance as required on
FLOWSERVE products, product users and maintenance personnel
should thoroughly review this manual prior to installing, operating or
performing any maintenance.
1.5 Valve and Actuator Variations

product variations, nor can they provide information for every possible

fied personal where the product is being used for its defined purpose.
If there are any uncertainties in this respect particularly in the event of

the appropriate Flowserve sales office.

responsibility for any damages that occur from using spare parts or
fastening materials from other manufactures. If FLOWSERVE products

check these for corrosion or deterioration before using these products.
