INSTALLATION

WARNING.

Before starting to install this equip- ment, read the Safety Summary in the Preface section of this manual. Failure to follow the safety instruc- tions could result in serious injury or death.

2-1 UNPACKING

If the Trace Oxygen (TO2) Analyzer Module is received as a separate unit, carefully examine the shipping carton and contents for signs of damage. Immediately notify the shipping car- rier if the carton or contents is damaged. Re- tain the carton and packing material until all components associated with the TO2 Ana- lyzer Module are operational.

2-2 ELECTROLYTE

Figure 4-1). Be careful not to lose these screws as they have metric threads. Carefully lift out the Sensor assembly and remove from the analyzer module. Place on a flat surface and remove the black Sensor cover by unscrewing counter- clockwise.

Add distilled or deionized water to the Sensor to the maximum level indication on the Sensor reservoir. Let Sensor stand for approximately 15 minutes and check for leaks around the base of the reservoir, and at the seams and corners. If a leak is found, contact the factory be- fore proceeding. Drain the Sensor.

Fill the Sensor with one bottle of electro- lyte supplied with the analyzer module. Use the entire contents of the bottle.

NOTE

Before installation of the TO2 Analyzer Mod- ule, electrolyte must be added to the Sensor. Follow the procedure described in Section 2- 2a.

After addition of electrolyte, locate the ana- lyzer module on an appropriate mounting surface and connect the network cable to ei- ther the NETWORK 1 or NETWORK 2 con- nection on the Analyzer Module, and the NETWORK connection on the Platform net- work I/O port. (See Figure 2-1 and Figure 2-4.)

a.Electrolyte Addition

Before adding electrolyte to the Sensor, it is recommended to check the Sensor for possible leakage caused by damage in shipment. To check the Sensor for leak- age, remove the top cover of the Analyzer Module and locate and remove the 5 mounting screws which hold the Sensor Assembly (Sensor, flow meter, plumbing, inlet/outlet fittings) to the module (see

Do not add water. The volume and concentration of the bottled electrolyte is pre-measured.

Reinstall the black Sensor cover and carefully reinstall the Sensor Assembly inside the Analyzer Module. Do not tilt the Sensor Assembly excessively as electrolyte may leak out.

2-3 LOCATION

(See Figure 2-2) The TO2 Analyzer Module comes standard with mounting ears for easy installation on flat, horizontal surfaces. Install the TO2 Analyzer Module in a clean, weather- proofed, vibration-free location free from ex- treme temperature variations and moisture. For best results, install the instrument near the sample stream to minimize sample trans- port time.

Operating ambient temperature is 0 °C to 45 °C (32 °F to 81 °F). Temperature change should not exceed 10 °C (18 °F) per hour.
