To refill the BDS sensor:
1. Open the front door and swing it open.
2. Unscrew the sensor cap and disconnect sensor cable from the
BDS sensor.
3. Pour the electrolyte from the five small bottles into a larger
container.
4. Sparge the electrolyte with nitrogen gas at a flow of 100 CCM
for about 1/2 hour then pour into the provided wash bottle.
5. Ref. to Figure 3.7 for the method of adding electrolyte to the
sensor. It is important that as the sensor is being filled with the
electrolyte, filling is accomplished without trapping gas bubbles
in the lower part of the sensor.
