!NOTE
Upon completing installation, make sure that the Hazardous Area Oxymit- ter DR is turned on and operating prior to firing up the combustion process. Damage can result from having a cold Hazardous Area Oxymitter DR ex- posed to the process gases.
During outages, and if possible, leave all Hazardous Area Oxymitter DR units running to prevent condensation and premature aging from thermal cycling.
If the ducts will be washed down dur- ing outage, MAKE SURE to power down the Hazardous Area Oxymitter DR units and remove them from the wash area.
