mended) at the sample tap. Locate the analyzer as close as possible to the
sample source.

and exhaust fitting (5). Discard the gaskets. Remove the cap from the
instrument air fitting (3). Keep the VCR fitting caps. If you have to
ship the analyzer or if it has to be disconnected for an extended period
of time, reinstall the caps using new gaskets.
