AGM300 - Installation Considerations

Locating the Monitor

The AGM300 should be centrally located in the facility and should be easily accessible for visual monitoring and servicing. Intake sample lines can be up to 500 feet in length, but it is important to remember that sampling cycle time is proportional to the total number and length of individual sample lines.

Dirt, grease, and oils can adversely affect the operation of the AGM300. The monitor should be installed out of direct sunlight in a clean, dry area that is not subject to temperature or humidity extremes. Installation of the monitor in a mechanical room is acceptable provided reasonable environmental conditions exist. If there is a question, consider installing the unit outside of the mechanical room in a cleaner area of the facility.

Warnings and Cautions

WARNING – Drilling holes in the AGM300 and ADM800 enclosure will void the warranty. Please use knockouts provided for electrical connections.

WARNING - Do not operate this equipment in the presence of flammable liquids, vapors or aerosols. Operation of any electrical instrument in such an environment constitutes a safety hazard.

WARNING - Always de-energize the power supply before working inside the instrument.

CAUTION - The AGM300 contains sensitive electronic components that can be easily damaged. Be careful not to touch or disturb any of these components.

Inspection

The AGM300 has been thoroughly inspected and tested prior to shipment from the factory. Nevertheless, it is recommended that the monitor be re-checked prior to installation. Inspect the outside of the enclosure to make sure there are no obvious signs of shipping damage. Open the door latches and inspect the interior of the instrument for loose components that may have become dislodged during shipment. If damage is discovered, please contact the nearest Bacharach Service Center for assistance.
