Replacing a Sensor, Pump, or Pump Filter
aWarning
To avoid personal injury, use only sensors
specifically designed for the detector. See the
section,
Replacement Parts and
Each sensor has a high degree of resistance to common
vapors and gases. A sensor will most likely clear itself if you
remove the detector to a clean environment and wait 10 to
30 minutes. Do not expose a sensor to the vapors of
inorganic solvents (e.g., paint fumes) or organic solvents.
The
Troubleshooting
section describes problems caused by
a sensor in need of calibration or replacement.
The internal pump draws air over the sensors. If the pump
stops working or the pump filter becomes clogged, the
detector activates the pump alarm. Turn off the detector
immediately.

Accessories.
Pump Filter
Check if the pump filter is clogged by viewing the pump filter
through the window on the back of the detector. Clean the
filter using a soft, clean brush and clean, warm water. Let the
filter dry before replacing it.
If the pump alarm activates a second time, insert a new
pump filter. If the alarm activates with the new filter in place,
