MECHANICAL INSTALLATION

Selecting Location

1.The location of the OCX 8800 in the stack or flue is most important for maximum accuracy in the oxygen analyzing process. The probe must be positioned so the gas it measures is representative of the process. Best results are normally obtained if the transmitter is positioned near the center of the duct (40-60% insertion). Longer ducts may require several transmitters since the oxygen and combustibles can vary due to stratification. A point too near the wall of the duct or the inside radius of a bend, may not provide a representative sample because of the very low flow conditions. The sensing point should be selected so the process gas temperature falls within the range of probe material used. Figure 2-1through Figure 2-3provide mechanical installation references. The ambient temperature inside the electronics housing must not exceed 185°F (85°C).

2.Check the flue or stack for holes and air leakage. The presence of this condition will substantially affect the accuracy of the oxygen and combustibles readings. Therefore, either make the necessary repairs or install the transmitter up stream of any leakage.

3.Ensure the area is clear of internal and external obstructions that will interfere with installation and maintenance access to the unit. Allow adequate clearance for the removal of the OCX 8800.

Do not allow the temperature of the electronics housing to exceed 185°F (85°C) or damage to the electronics may result.

Whenever a positive stack pressure exists at the installation site, be sure to connect all pneumatic lines prior to installing the OCX 8800 in the stack or ductwork. Failure to connect the pneumatic lines can allow the flow of contaminants into the OCX 8800 ports.

Before installing the OCX 8800 into a hot stack or ductwork, make sure that the OCX 8800 is turned on and at normal operating temperature. Exposing a cold OCX transmitter to hot process gases can cause permanent damage to the equipment.

Installation

1.Ensure all components are available to install the OCX 8800.

2.The OCX 8800 may be installed intact as it is received.

3.Weld or bolt adapter plate (Figure 2-2)onto the duct.
