Using your Cl Cartridge
2
Please ensure that the following points are noted when the cartridge is in service.
1. Always use PTFE tubing (maximum length of 500mm) and a flow rate of
500ml/min when calibrating the Cl
2. Apply all gases to the port marked OUTLET (not INLET) on the Flow
Housing.
3. 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, CO, Flammable.

4. When performing a Span Calibration on the Cl
flow Cl calibration span gas through connected tubing for a minimum of 15
2
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
Cl channel.
2
5. Do not apply Span Calibration gas to the Impact Pro for greater than 5
minutes. Again failure to do so may result in a false calibration of the Cl
channel.
6. This cartridge is not suitable for pumped mode operation.
7. Due to the open nature of the Stainless Steel filter, there is a greater risk
of water damage occurring to the instrument. Every attempt should be
made to keep the instrument dry.
8. Refer to the CAUTION given in
recommended daily checks on your gas detector.
