2.0 INSTALLATION
2.1 Mechanical Installation
Remove all packaging material, the protective flange cover and visually check
the CMC Series. If the CMC Series appears damaged, notify Brooks Instrument
immediately. Retain packaging materials for inspection. Do not use if damaged.
If the CMC Series is not going to be used immediately, then replace the protec-
tive flange cover and store in an area where the temperature range is controlled
between -50°C to +125°C.
CMC Series can be mounted in any orientation on the vacuum system. To avoid
the build-up of debris or condensable material in the measurement cavity of the
CMC Series (which may cause measurement errors), it is recommended that
you install the CMC Series vertically with the tube facing down. Outline drawings
showing the external dimensions are shown in Figure 1, Figure 2, and Figure 5.
To connect the CMC Series to your system, use the appropriate hardware for the
type of fitting:
• Use a Cajon ® Ultra Torr type of compression coupling to connect to the 0.5”
OD tube.
• Use an O-ring/centering ring and clamp to connect to the KF-16 and 25 flange
options.
NOTE: A stepped O-ring may be used to connect the KF-16 flange to an KF-10 flange on
the system.
Use a Male VCR ® style face seal fitting and sealing gasket to connect the VCR ®
female fitting.
NOTE: Tighten threaded fittings in accordance with the manufacturer’s specifications.
