SAFETY GUIDE

2 GENERAL INFORMATION

2.1 General application

Keystone Rack and Pinion Pneumatic F89
actuators are intended for the automation and
operation of quarter-turn valves like butterfly &
ball valve.

Rack and Pinion actuators can also be used to
operate venting louvers or any other quarter­turn applications.

This product was intended for a specific range
of service conditions: pressure, ambient
temperature, operating media, and possibly
other specifications. Do not expose the product
to service conditions or variables other than
those for which the product was intended.

If you are not sure what these conditions or
variables are, contact your Emerson sales
office for assistance. Provide the product type,
size, serial number and all other pertinent
information that you have available.

2.2 Inspection and maintenance schedules

Keystone F89 - Series actuators must be
inspected periodically and maintained as
needed. Refer to the maintenance section of
manual VCIOM-03059-EN for more detailed
information.

2.3 Parts ordering

When ordering parts for older products, always
specify the type, size and serial number of
the product and provide all other pertinent
information that you can, such as part material,
age of the product, and general service
conditions. If you have reconfigured the product
since it was originally purchased, include that
information with your request.

WARNING - USE GENUINE PARTS

Use only genuine replacement parts. Components
that are not supplied by Emerson should not,
under any circumstances, be used in any Keystone
F89 product. Use of components not supplied by
Emerson may void your warranty, might adversely
affect the performance of the product, and could
cause personal injury and property damage.

The schedule for inspection can only be
determined based on the severity of your
service conditions. Your installation might
also be subject to inspection schedules
set by applicable governmental codes and
regulations, industry standards, company
standards, or plant standards.

In order to avoid increasing dust explosion
risk, periodically clean dust deposits from all
equipment.

When equipment is installed in a hazardous
area (potentially explosive atmosphere), prevent
sparks by proper tool selection and avoiding
other types of impact energy.

Proper care must be taken to avoid
generation of static electricity on the non­conductive external surfaces of the equipment
(e.g. rubbing of surfaces, etc.). The actuator's
surface temperature is dependent upon
process operating conditions.
