Installation, Start Up and Shut Down DF-760E 23
CAUTION
The DF-760 is for indoor use only. It should not be located in an area where it
will be subjected to particulate, condensed moisture, caustic atmosphere,
temperature extremes, or operation outside of any limits listed in section 3
Specifications.
The DF-760 is designed to be rack mounted. Ensure that the rack slides, or
support rails, are rated to support a 30 kg analyzer. Use screws in all four front
panel rack mount locations.
4.1.4 Add Electrolyte to the Oxygen Sensor
1. Open the front door of the analyzer.
2. Locate the oxygen sensor (see Figure 2) and remove the gold cap from the top.
3. Pour one full bottle (100 mL) of Servomex
E
-Lectrolyte Gold into the sensor.
4. Replace the cap securely on the top of the sensor.
5. Allow the sensor to sit for 60 minutes before connection to gas flow or power.
For best performance at initial start or anytime the electrolyte is changed,
it is important to allow the sensor to sit with electrolyte in it for 60
minutes
before the gas is allowed to flow through the sensor, or power is
connected.
If the electrolyte level is low in the oxygen sensor, only Servomex
Replenishment Solution should be added to the sensor.
Do not add
electrolyte solution to restore the electrolyte level. Do not overfill.
4.1.5 Vacuum Source
