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).
