Installation
2.1 Location
The analyzer should be installed where it will not be subject to the
following conditions:
1. Direct sunlight
2. Drafts of air
3. Shock and vibration
4. Temperatures below 30° F or above 110° F
The analyzer should be placed as close as possible, subject to the above
conditions, to the sample point to minimize the effects of sample line lag
time on the analysis.
An outline diagram, showing the location and identification of the gas
line and electrical conduit connections, as well as the physical dimensions of
the analyzer case, is included in the drawings at the rear of the manual.
2.2 Electrical Connections
A single-phase, 110 to 120 Volt, or 220 to 240 Volt, 50 or 60 Hz line,
capable of delivering 2-1/2 amperes of current continuously, is required to
operate the analyzer. Primary power connections are made on the terminal
strip mounted on the mother board, behind the rear access cover. A solid
water-pipe ground should be provided for personnel protection. When
connecting the power source, polarize the connections as indicated on the
interconnection diagram at the rear of the manual.
