NPACKING
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 carrier if the carton or contents is damaged. Retain the carton and packing material
until all components associated with the TO2 Analyzer Module are operational.
2.2 A
SSEMBLY
Before installation of the TO2 Analyzer Module, electrolyte must be added to the Sensor.
Follow the procedure described below under section 2.2.1.
After addition of electrolyte, locate the analyzer module on an appropriate mounting surface
and connect the network cable to either the NETWORK 1 or NETWORK 2 connection on
the Analyzer Module, and the NETWORK connection on the Platform network I/O port. (See
Figures 2-1 and 2-4.)

DDITION
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 leakage, 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
Figure 4-2). 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 counterclockwise.
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 before proceeding. Drain the Sensor.
Fill the Sensor with one bottle of electrolyte supplied with the analyzer module. Use the
entire contents of the bottle.
