Other Maintenance
If it is necessary to perform maintenance on the analyzer while the
circuits are energized and with the Electronics Enclosure door open,
first monitor the area for flammable gases and proceed only when the
area is safe.
When the Electronics Enclosure is open, take appropriate precautions
to avoid electrical shock. Hazardous voltages are present inside.
If a procedure for a certain maintenance task is not described in the ana-
lyzer User Manual, contact AMETEK Service Personnel for details about
performing the required maintenance.
When performing equipment maintenance in hazardous areas, all
safety standards and procedures must be followed, as specified by the
Owner Company, local electrical-inspection authority, and National/
EU regulations.
Sample System Leakage Test
After performing any maintenance procedures such as replacement of
parts or cleaning of the analyzer components, you must check the sample
system to determine if any of the procedures has affected the integrity of
the sample system.
The sample system should be charged with instrument air, sealed off,
and checked after a period of time for a drop in pressure.
1. Turn off AC power.
