Specifications
This product was intended for a specific range of service conditions‐‐pressure, pressure drop, process and ambient
temperature, temperature variations, process fluid, 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
other pertinent information that you have available.
Inspection and Maintenance Schedules
All products must be inspected periodically and maintained as needed. 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 location (potentially explosive atmosphere), prevent sparks by proper
tool selection and avoiding other types of impact energy.
Parts Ordering
Whenever ordering parts for older products, always specify the serial number of the product and provide all other
pertinent information that you can, such as product size, part material, age of the product, and general service
conditions. If you have modified the product since it was originally purchased, include that information with your
request.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson should not, under any
circumstances, be used in any Fisher product, because they may void your warranty, might adversely affect the
performance of the product, and could cause personal injury and property damage.
