Shutdown procedure
This chapter describes the procedure to be followed when shutting down the analyzer.
DANGER
ELECTRIC SHOCK
The analyzer operates using mains voltage that is dangerous to life. Make sure that the
power ON/OFF switch at the rear of the panel is set to OFF and the power cable plug is
removed.
The analyzer MUST be earthed using a grounded three core cable suitable for the rating
defined in the General Characteristics
Death or personal injury may result if this is not observed.
DANGER
FAILURE TO LOCK-OUT THE GAS HANDLING SYSTEM
Always lock 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.
Death or personal injury may result if this is not observed.
DANGER
FAILURE TO VENT SAMPLE GAS
The sample gas in the system must be vented to prevent fire or explosion during
maintenance and to prevent damage to the analyzer 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 system for returning the sample gas to run for five minutes to allow
any sample gas in the system to be returned to the exhaust.
