Introduction
General Precautions
• This unit must be supplied with a grounded receptacle.
• Disconnect the AC power cord before removing any covers.
• Replace or repair faulty or frayed insulation on power cords.
• Perform periodic leak checks on supply lines, fittings, and pneumatic plumbing.
• Arrange gas lines so they can not become kinked, punctured, or otherwise
damaged, and will not interfere with foot traffic.
• Turn off the main power switch and disconnect the main power cord before
using a liquid solution to locate leaks.
• Do not restrict airflow on the back and/or bottom of the unit.
• Wear safety glasses to prevent possible eye injury.
• Do not replace blown fuses inside the detector controller. Only trained service
personnel should access the interior of the detector controller.
• Do not perform unauthorized modifications or substitute parts that are not OI
Analytical original parts to the instrument.
• To prevent burns, verify that all heated areas have cooled before handling or
wear adequate hand protection.
Compressed Gas Cylinders Precautions
• Compressed gases should be stored and handled strictly in accordance with
relevant safety codes.
• Fasten all cylinders securely to an immovable structure or permanent wall.
• Store or move cylinders only in a vertical position. Do not move or transport
cylinders with regulators attached.
• Use only approved regulators and tubing connections.
• Connect cylinders to instruments with pressure ratings that are significantly
greater than the highest outlet pressure from the regulator.
• Nitrogen and helium have been identified as asphyxiants. These gases and the
cylinders containing them should be handled and stored in a manner consistent
with OSHA regulations. Adequate ventilation should be maintained in areas
where these materials are used and store. The analyst should avoid prolonged
exposure to high concentrations of these gases.
