WARNING!
Turning the pump off while the probe is in the flue will leave toxic
gases inside the analyzer. Once data has been read, it is advisable to
purge the unit with fresh air as soon as possible. To do this, with the
probe removed from the flue, turn ON the pump. Always allow the
readings to return to zero (00 for CO) prior to shutting the unit off.
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 analyzer and damage the pump and sen-
sors. Once the probe is removed from the flue and the readings have
returned to ambient levels rotate the selector to “OFF”and switch off
the analyzer. The instrument will count down from 30 to switch off.
