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.

ESD (Electrostatic Discharge)
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.
