Page 14: Taking A Pressure Reading
IMR1100 Taking a Pressure Reading An optional differential pressure sensor is available for the IMR 1100. With this option a flue draft measurement can be made or a differential pressure test made. To take a flue draft reading, connect the standard probe to the pressure sensor inlet P2 and insert the probe in the flue.
Page 15: Normal Shutdown Sequence
 2003 - IMR Environmental Equipment, Inc May 2003 IMR1100 Normal Shutdown Sequence DO THIS EVERY TIME YOU USE THE ANALYSER WARNING! THE PROBE WILL BE HOT FROM FLUE GASES Remove the probe from the flue and allow it to cool naturally. Do not immerse the probe in water, as this will be drawn into the analyser and damage the pump and sensors.
