Ametek 241CE II Operator's Manual page 51

In all cases, install the analyzer at an accessible location as close as possible
to the sample gas extraction point to:
• Minimize sample response time.
• Minimize the amount of sample gas required for purging the Measur-
ing Cell and sample system.
• Reduce the workload of the filter.
• Minimize heating requirements (for Sample Line, if required).
To install the analyzer:

Do not install the Heatsink/Measuring Cell Assembly until after the
analyzer has been installed (see "Installing the Heatsink/Measuring
NOTE
Cell Assembly."
Non-Shelter Installations
In a suitable indoor, accessible location as close as possible to the sample
gas extraction point, install the analyzer on a vibration-free wall or instru-
ment rack.
Ensure appropriate clearances are made to allow for heat dissipation and
access for servicing the analyzer. Clearances must be at least:
- 150 mm (6") on each side of backpan
- 75 mm (3") at top and bottom of backpan
- 900 mm (36") in front of analyzer
Shelter Installations
In a suitable location as close as possible to the sample point, install the
analyzer in a vibration-free location.

For each installation method, AMETEK recommends mounting the
analyzer higher than the process pipe, since liquids can occasionally
NOTE
appear in the process stream and in the Sample Line. This will allow
these liquids in the Sample Line to drain back into the process pipe.
