SECTION 2.0

INSTALLATION

2.1GENERAL. This section provides instructions for the Model 430 Dissolved Oxygen Sensor.

2.2UNPACKING AND INSPECTION. Inspect the ship- ping container and remove the sensor. Carefully check the sensor and its associated hardware for any dam- age. Report any damage to the carrier immediately.

2.3MECHANICAL INSTALLATION. The sensor comes in four different configurations. Follow the instruction for the configuration being installed. See Figure 2-2 for dimensions. Figure 1-2 illustrates optional bracket assembly for sensor installation in tanks or ponds.

2.4Electrical Installation. Connect the sensor to the transmitter as shown in Table 2-1.

2.3.1Codes 01 and 02 (see Figure 2-1). These config- urations are for flow through measurements. Install the tee using 1-1/2 inch PVC. For the angle flow (Code 01), make sure the flow enters at the opening opposite the sensor, so that the sample flows directly into the membrane.

2.3.2Codes 03 and 04 (see Figure 5-3 and Figure 5- 4). These configurations are for submersion into a tank or pond. The Code 03 configuration requires a flow past the sensor of 1.5 feet per second (0.5 m/s). The Code 04 configuration is for stagnant or still tanks and ponds.
