MAINTENANCE
This chapter discusses preventive maintenance (and certain extended
maintenance) to keep the Heated Acid Gas Sample Probe and its Heater
Assembly operating at peak efficiency.
Safety Considerations
Before working on the HAG Probe, read the entire procedure you
will be performing to learn how to safely perform maintenance
on the HAG Probe.
Personnel should be thoroughly familiar with the operation of the ana-
lyzer and HAG Probe before performing the maintenance procedures
described in this chapter.
Before performing any maintenance on the HAG Probe and/or its
Heater, review and follow all safety information in this chapter and
under “Personnel and Equipment Safety Information” following the
Table of Contents. This information describes procedures to follow to
avoid personal injury and/or damage to the equipment. All regulato-
ry agency and personnel safety procedures for your jurisdiction
must be followed.
To prevent an explosion, test the area around the analyzer for flamma-
ble gases and proceed with maintenance only when the area is found
to be safe (nonhazardous).
Generally, the HAG Probe and its Heater require limited maintenance.
The “Preventive Maintenance Schedule” lists general maintenance to fol-
low, to ensure continued and proper operation of the HAG Probe.
