CAUTION
CAUTION
Any Brooks Instrument mass flow meter or flow controller with a 15
pin D-Connector PC Board bearing the "CE Mark" must use a 100%
shielded cable and metal shell mating connectors. The shield is tied
over 360 degrees to the shell at both ends. This is mandatory to be in
compliance with the EMC Directive (89/336/EEC). Refer to
Appendix A.
Recommended Installation Procedures
a. The Model 5866 should be located in a clean, dry atmosphere relatively
free from shock and vibration.
b. Leave sufficient room for access to the electrical components.
c. Install in such a manner that permits easy removal if the instrument
requires cleaning.
When used with a reactive (sometimes toxic) gas, contamination
or corrosion may occur as a result of plumbing leaks or improper
purging. Plumbing should be checked carefully for leaks and the
controller purged with dry nitrogen before use. See Brooks’
Technical Bulletin T-086 for further information.
CAUTION
d. The Model 5866 pressure controller may be installed in any position.
Note: The control valve in the Model 5866 provides precision control and is
not designed for positive shut-off. If positive shut-off is required, it is
recommended that a separate shut-off valve be installed in-line.
