IMPORTANT! READ INSTRUCTIONS BEFORE STARTING!

Be sure that these instructions are carefully read and understood before any

operation is attempted. Improper use of this device in some applications may result in

damage or injury. The user is urged to keep this book filed in a convenient location for

future reference.

These instructions may not cover all details or variations in equipment or cover

every possible situation to be met in connection with installation, operation or main-

tenance. Should problems arise that are not covered sufficiently in the text, the pur-

chaser is advised to contact Bristol for further information.

EQUIPMENT APPLICATION WARNING

The customer should note that a failure of this instrument or system, for

whatever reason, may leave an operating process without protection. Depending upon

the application, this could result in possible damage to property or injury to persons.

It is suggested that the purchaser review the need for additional backup equipment

or provide alternate means of protection such as alarm devices, output limiting, fail-

safe valves, relief valves, emergency shutoffs, emergency switches, etc. If additional

in-formation is required, the purchaser is advised to contact Bristol .

RETURNED EQUIPMENT WARNING

When returning any equipment to Bristol for repairs or evaluation, please note

the following: The party sending such materials is responsible to ensure that the

materials returned to Bristol are clean to safe levels, as such levels are defined and/or

determined by applicable federal, state and/or local law regulations or codes. Such

party agrees to indemnify Bristol and save Bristol harmless from any liability or

damage which Bristol may incur or suffer due to such party's failure to so act.

ELECTRICAL GROUNDING

Metal enclosures and exposed metal parts of electrical instruments must be

grounded in accordance with OSHA rules and regulations pertaining to "Design

Safety Standards for Electrical Systems," 29 CFR, Part 1910, Subpart S, dated: April

16, 1981 (OSHA rulings are in agreement with the National Electrical Code).

The grounding requirement is also applicable to mechanical or pneumatic in-

struments that include electrically-operated devices such as lights, switches, relays,

alarms, or chart drives.

EQUIPMENT DAMAGE FROM ELECTROSTATIC DISCHARGE VOLTAGE

This product contains sensitive electronic components that can be damaged by

exposure to an electrostatic discharge (ESD) voltage. Depending on the magnitude

and duration of the ESD, this can result in erratic operation or complete failure of the

equipment. Read supplemental document S14006 at the back of this manual for

proper care and handling of ESD-sensitive components.
