Hazardous Area Oxymitter DR

4.If using the optional ceramic diffusion element, the vee deflector must be cor- rectly oriented. Before inserting the Hazardous Area Oxymitter DR, check the direction of gas flow in the duct. Ori- ent the vee deflector so the apex points upstream toward the flow (Figure 2-5). This may be done by loosening the setscrews and rotating the vee deflector to the desired position. Retighten the setscrews.

5.In vertical installations, ensure the sys- tem cable drops vertically from the Haz- ardous Area Oxymitter DR and the conduit is routed below the level of the termination housing. This drip loop minimizes the possibility that moisture will damage the electrical connections (Figure 2-6).
