Emerson Process Management IB106-340 instruction manual Orienting the Optional Vee Deflector

Instruction Manual

IB-106-340 Rev. 2.4 April, 2001

Oxymitter 4000

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).
