Appendix A: General Maintenance
All combustion analyzers use consumable items such filters and probes. These
items are user serviceable and can be taken care of by the operator.
The consumable items that will require operator attention are the water trap / fil-
ter assembly, flue probe, pump protection filter, and ambient temperature probe.
The recommended maintenance schedule for your analyzer is as follows:
Maintenance Performed
Frequency
Water trap Check Once per week (Once per day for analyzers
Filter Check that see heavy use or are used in oil fired
applications)
Pump Operation Check Once per month (More often for analyzers
Flue Probe Integrity Check that see heavy use or are used in oil fired
Thermocouple Probe Check applications)
Water Trap Check
Visually check the water trap for:
1. Cracks in the bowl.
2. Broken ears on the bowl where the lid locks on.
3. Broken ears on the lid.
4. Worn out o-ring on the lid.
5. Loose connection to the flue probe tubing.
Filter Check
Signs of dirty or water saturated filters are a slow pump, flow error displayed
when the flue probe is connected, and measurements that take longer than nor-
mal.
TPI analyzers use three filters to protect the pump and sensors. The first filter to
check is the A763 mini pump protection filter. (see picture below)
Strain Relief Spring Inspection Window
A763 Pump Protection Filter
Look in the inspection window to check the filter. When the filter material
becomes dark, pull the black nose cone out of the tubing and replace the ball fil-
ter inside.
