3-2 | Model 933S UV Analyzer
Safety Considerations
Before installing and powering up the analyzer, review and follow all
safety information in this chapter and under “Personnel and Equip-
ment Safety Information” following the Table of Contents. This infor-
mation describes procedures to follow to avoid personal injury and/
or damage to the equipment. All regulatory agency and personnel
safety procedures for your jurisdiction must be followed.
Under normal operating conditions, lethal concentrations of H
2
S and
other toxic gases from the sample stream may be present within the
sample system. The sample system is defined as all components in the
analyzer system through which sample gas passes.
A breathing apparatus must be worn when installing/removing
equipment from the sample gas extraction point. The sample stream is
under positive pressure, and injury or death from inhaling toxic gases
in the sample stream could result from attempting to install/remove
equipment without the use of a breathing apparatus.
Pre-Installation Requirements
Storage Prior to Installation
If the analyzer and its Optical Bench Assembly are stored for any period
of time prior to installation, store the equipment in an environment where
it is not subject to dripping or splashing liquids, corrosive gases, high
humidity, or excessive heat or cold. Recommended storage conditions
include:
Temperature: 0 °C to 50 °C (32 °F to 122 °F)
Relative Humidity: < 70 %
Failure to comply with these storage conditions will void your warranty.
