4. If using the optional ceramic diffusion
element, the vee deflector must be cor-
rectly oriented. Before inserting the
Oxymitter 4000, check the direction of
gas flow in the duct. Orient the vee de-
flector so the apex points upstream to-
ward the flow (Figure 2-7). 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
Oxymitter 4000 and the conduit is
routed below the level of the electronics
housing. This drip loop minimizes the
possibility that moisture will damage the
electronics (Figure 2-8).
