Special Notes for NO

It is important that you read all of the notes below before installation or use of your
new cartridge.
Installation of your NO
Note
Cartridge Installation or Replacement must never be carried out in a
hazardous area.
1. If a cartridge was previously fitted to the Impact Pro into which the NO
cartridge is to be installed, remove the Front Cover Grille using the Allen
Key provided in the bottom of the Impact Pro. Unscrew the screw in the
center of the cartridge and lift the cartridge from the Impact Pro.
2. Place the NO
home using the Allen Key. Guide the cartridge if necessary using your
fingers to ensure that it is seated correctly.
3. Replace the Pump Seal with the one provided with your cartridge and
replace the Front Cover. Refit the Allen Key into the bottom of the Impact
Pro.
4. Allow 20 minutes for the sensors to stabilize before first use.
5. To complete installation of the cartridge, switch the Impact Pro on and
accept the New Configuration when prompted to do so.
Using your NO
2
Please ensure that the following points are noted when the cartridge is in service.
1. The operating
lowest sensor fitted. The temperature range of the NO
to +50°C.
2. Always use PTFE tubing (maximum length of 500mm) when calibrating
the NO

3. When sampling remotely (i.e. using the internal sample pump or hand
aspirator together with tubing) users should be aware of increased sample
times. For NO
for every 10m of tubing used.
4. When performing a Span Calibration on the NO
practice to flow NO
minimum of 15 minutes without the flow adapter fitted to the Impact Pro
before attempting a span calibration. Failure to do so may result in a false
calibration of the NO
5. The accuracy of the instrument must be checked with known concentration
calibration gas before each day's use. If any sensor fails, recalibrate the
Impact Pro before using or alternatively replace the cartridge. Please refer
to Section 4.9 on general instructions on how to calibrate.
6. Apply calibration span gas at a rate of 300 ml/min for a period of 1 minute
before starting the span calibration on the sensor.
7. With regard to the actual sensors fitted, please perform span calibrations
on the sensors of the Impact Pro cartridge in the following order: Cl
H S, NO
