7. TROUBLESHOOTING AND MAINTENANCE
The ASAP 2460 system has been designed to provide efficient and continuous service. However, to
get the best results over the longest period of time, certain maintenance procedures must be followed.
This chapter includes troubleshooting information, recommended preventive maintenance procedures,
and routine maintenance procedures.
Troubleshooting
Most operational problems are caused by the following:
• Leaks (commonly around the sample tube O-ring at the analysis port)
• Sample weighing errors
• Use of too much analysis bath fluid in the dewar at the start of an analysis
• Entry of incorrect system volume for analysis

Always check these first when expected analysis results are not obtained. Some common operational
problems, which are not indicated on the computer screen, and their respective causes and solutions
are provided in the following table.
What Happened Why What To Do
Analysis dewar cannot
be raised (or lowered). Elevator that moves dewar stuck
in up position, down position, or
somewhere in between. Check for possible obstruction to
elevator movement.
Vacuum pump system
makes loud noise
continuously. Sample tube connector nut is
loose. Turn the connector nut clockwise
to tighten.
