Essential Instructions

Read this page before proceeding!

Brooks Instrument designs, manufactures and tests its products to meet many national and international standards. Because
these instruments are sophisticated technical products, you must properly install, use and maintain them to ensure they
continue to operate within their normal specifications. The following instructions must be adhered to and integrated into your
safety program when installing, using and maintaining Brooks Products.

Read all instructions prior to installing, operating and servicing the product. If this instruction manual is not the correct
manual, please see back cover for local sales office contact information. Save this instruction manual for future reference.

If you do not understand any of the instructions, contact your Brooks Instrument representative for clarification.

Follow all warnings, cautions and instructions marked on and supplied with the product.

Inform and educate your personnel in the proper installation, operation and maintenance of the product.

Install your equipment as specified in the installation instructions of the appropriate instruction manual and per applicable
local and national codes. Connect all products to the proper electrical and pressure sources.

To ensure proper performance, use qualified personnel to install, operate, update, program and maintain the product.

When replacement parts are required, ensure that qualified people use replacement parts specified by Brooks Instrument.
Unauthorized parts and procedures can affect the product's performance and place the safe operation of your process at
risk. Look-alike substitutions may result in fire, electrical hazards or improper operation.

Ensure that all equipment doors are closed and protective covers are in place, except when maintenance is being
performed by qualified persons, to prevent electrical shock and personal injury.

Pressure Equipment Directive (PED)

All pressure equipment with an internal pressure greater than 0.5 bar (g) and a size larger than 25mm or 1" (inch) falls under the
Pressure Equipment Directive (PED). The Directive is applicable within the European Economic Area (EU plus Norway, Iceland
and Liechtenstein). Pressure equipment can be traded freely within this area once the PED has been complied with.

Section 1 of this manual contains important safety and operating instructions related to the PED directive.

Meters described in this manual are in compliance with EN directive 97/23/EC module H 

Conformity Assessment.

All Brooks Instrument Flowmeters fall under fluid group 1.

Meters larger than 25mm or 1" (inch) are in compliance with category I, II, III of PED.

Meters of  25mm or 1" (inch) or smaller are Sound Engineering Practice (SEP).

Handling Procedure:

1. Power to unit must be removed.
2. Personnel must be grounded, via a wrist strap or other safe, suitable means before any printed circuit card or other internal

device is installed, removed or adjusted.

3. Printed circuit cards must be transported in a conductive container. Boards must not be removed from protective enclosure

until immediately before installation. Removed boards must immediately be placed in protective container for transport,
storage or return to factory.

Comments

This instrument is not unique in its content of ESD (electrostatic discharge) sensitive components. Most modern electronic
designs contain components that utilize metal oxide technology (NMOS, SMOS, etc.). Experience has proven that even small
amounts of static electricity can damage or destroy these devices. Damaged components, even though they appear to function
properly, exhibit early failure.
