6. Remove the rubber inlet cover from the top of the DI water cartridge.
7. Slide the water bottle nozzle into the inlet hole. Make sure the tubing that connects to Port "B" is
positioned higher than the DI water cartridge, and then gently squeeze the water bottle. Be sure to fill
the reservoir until the water reaches the Full line.
8. Connect the fitting labeled "D" to the barb labeled "B" on top of the DI water cartridge.
9. Slide the DI water cartridge into the bracket and rotate it into the retaining clip until it snaps into place.

perpendicular to the bracket.

manipulate the tubing to work the air bubbles out.
12. Keep the Analyzer powered on for 2 minutes.
13. After 2 minutes, turn the Analyzer off.
