11. Replace the Large and Small Access Lid then press the
Dissolution side START button.
The GranuFlo I Dissolution Unit will proceed to the MIX
Operation.
12. During the MIX Operation, the solution is mixed for a period of forty-five
(45) minutes allowing the granules to completely dissolve. The GranuFlo I
Dissolution Unit will then automatically step to the DEAERATION Operation.
13. The DEAERATION Operation is five (5) minutes during which the entrapped
air (bubbles) are allowed to separate out of the solution. Upon completion,
the GranuFlo I Dissolution Unit will automatically step to FINAL FILL
Operation, and the Final Fill Indicator Light will illuminate.
14. In the FINAL FILL Operation, the fill valve will OPEN and the GranuFlo I
Dissolution Unit will fill to the final water level.
15. When the final water level is reached, the Unit automatically step to
HOMOGENIZE Operation. Verify that the solution level is touching the Final-
Fill Sensor. CLOSE the water supply valve to the GranuFlo I Dissolution Unit.
16. During HOMOGENIZE Operation, the Mixer will mix the solution for ten (10)
minutes. When the HOMOGENIZE Operation is complete, the Transfer
Indicator LED will flash. Remove the Large Access Lid and look into the Tank
to make sure the granules have dissolved and the solution is colorless.
17. Once you have verified the granules are dissolved and the solution is
colorless, the solution is ready for Specific Gravity testing. If the granules
have not dissolved and/or the solution is not colorless, call Technical Service
(1-800-227-2572) for further instructions.
