Maintenance

The 10.6 eV PID lamp has a 1-year warranty. The “Lamp” error is an
indication of a problem with the lamp current. A dirty or contaminated
sensor often causes high readings of the VOC sensor. A weak or
inoperative lamp often causes low readings or no response to test
gas. If the UV lamp is on while the error message persists, then it is
necessary to adjust the lamp threshold.
Refer to Adjust Lamp Failure
Threshold on page 27.
Sampling Pump Replacement
The sampling pump is a positive displacement piston pump, which
needs to be replaced as it approaches the end of its life span. The
pump’s draw capability reduces significantly as it consumes a greater
amount of energy to keep running. The sampling pump has a 1-year
warranty.
To replace
the pump:
Turn the monitor OFF and remove the cover.
The sampling pump is attached to the cover.
Remove the single screw holding the pump to the cover.
Gently pull the pump assembly off the cover.
Replace with a new pump assembly and reassemble.
