Overview
This operator’s manual describes the 35-3001A-13-XX carbon dioxide/carbon monoxide sample-draw detector.
This manual also describes how to install, start up, maintain, and calibrate the sample-draw detector when using
it with a gas monitoring controller. A parts list at the end of this manual lists replacement parts and accessories
for the sample-draw detector.
