Annual PM services
Inspect and service the ACM 150 monitor in accordance with Service inspections
and procedures . If you have not already done so during the course of the past 12
months, replace these expendable items:
• Cabinet filters
• Gas cell filter
• In-line filters
• Gas cell windows
• Booster pump diaphragm / flapper valves
• Back-up pump vanes
(but only if the venturi pumps were not in use most of the time)
• FTIR Desiccant
If any of these items have been replaced during the past 12 months and pass
inspection, there is no need to replace them during the annual service.
Three year service
These services are recommended at least once every 3 years:
FTIR Optics Bench: The infrared source, HeNe laser and laser power supply have a
limited operating life. HA can provide a reconditioned bench to exchange for your
used bench, which is returned to HA for reconditioning.
Five year service
These services are recommended at least once every 5 years:
Sample Valves: Disassemble the valve manifolds and clean the valves with a solvent
to assure that the accumulation of deposits and particles are removed.
Cycle Valves: These valves are expected to eventually wear out. They can be
replaced as one subassembly.
