WARNING
HAZARDOUS GAS
The product stream that the analyzer is examining may be hazardous even at low concentrations. Therefore, take special care to
ensure that the sample gas return port either returns the sample gas to the product stream or discharges the sample gas to a
location that will not cause a hazard.
WARNING
HIGH PRESSURE GAS AND AIR
The calibration gas supply operates at a pressure that can cause injury, e.g., damage to eyes and skin or punctures from debris
blown by the high pressure gas or compressed air.
Always lock off or tag out the calibration gas supply when shutting down the analyzer.
WARNING
EXPLOSION HAZARD
Always lock-out/tag-out the gas handling system when shutting down the analyzer. Unauthorized operation of the gas handling
system when maintenance is being performed on the analyzer or its associated pipes/hoses may result in highly flammable gas
being released, causing fire or explosion.
Failure to observe this precaution will cause death, personal injury, and/or damage to persons.
WARNING
EXPLOSION HAZARD
The sample gas in the system must be vented to prevent fire or explosion during maintenance or during startup.
The sample gas in the pipes leading to the analyzer must be purged to prevent hazards to personnel during maintenance. Purging
the sample gas must be done in accordance with the safe working procedures for the site.
Allow the analyzer and the venting system to run for a minimum of five minutes to allow any sample gas in the system to be
returned to the exhaust.
WARNING
HEAVY ITEM
Handle the analyzer with caution during unpacking, installing, maintaining, and transporting to prevent crushing of hands, feet, or
other body parts.
The analyzer weighs 33 lb (15 kg) for the half rack system and 66 lb (30 kg) for the full rack system. Rosemount recommends that
the analyzer is moved by a minimum of two people when lifting and transporting the equipment.
Failure to properly handle the analyzer may cause injury to personnel, wear suitable protective gloves and protective footwear.
WARNING
PHYSICAL ACCESS
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users' equipment. This could
be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access
by unauthorized personnel to protect end users' assets. This is true for all systems used within the facility.
