WARNING
Before each day's usage sensitivity must be tested on a known concentration of the
gas to be detected equivalent to 25 – 50% of full scale concentration. Accuracy
must be within 0 to +20% of actual. Accuracy may be corrected by calibration.
The Catalytic Flammable Sensors sensitivity can be adversely affected by exposure
to certain substances (silicon and sulphur compounds are examples). Every effort
should be made to avoid exposure to these substances. Following an H
repeated gassing with H
sensor to verify its accuracy and a calibration performed if necessary.
By default, no alarms are provided for the 0-100%/Volume Flammable IR sensor.
The user can set up alarm levels via the ICU software.
Hydrogen (H ) cannot be detected using the IR principle.

Dispose of the spent cartridge and its packaging in accordance with local
regulations. Do not dispose of in fire.
