14. When the FINAL WATER LEVEL is reached, the unit will
automatically step to HOMOGENIZE Operation. Remove the Large
Access Lid and ensure the solution level has reached the Final Fill
Sensor. Place Large Access Lid onto the GranuFlo Dissolution Unit II .
Then, CLOSE the Water Supply Valve to the GranuFlo Dissolution
Unit II .
15. 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 Large Access Lid and
look into the tank to make sure the granules have dissolved and the
solution is colorless.
16. 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.

Once the Transfer Indicator Light flashes, the concentrate is ready to be tested. This test is done using a
hydrometer which measures the density of the acid concentrate. The resultant value is called the " specific
gravity ". The specific gravity is measured to verify that the concentrate has been properly mixed.

To determine a Specific Gravity Reading:
1.
Prepare the Hydrometer and the Hydrometer Cylinder:
•
Check the Hydrometer for cracks. Do not use a cracked Hydrometer .
•
Always handle the Hydrometer with care. Always hold it vertically by the top, as finger marks lower
down can affect the accuracy of the instrument.
•
The Hydrometer should never be held by the stem horizontally.
•
Rinse the hydrometer and the hydrometer cylinder separately with purified water before checking
solution for specific gravity. The purified water source must meet ANSI/AAMI or ISO standards for
dialysis currently ANSI/AAMI RD62 , or ISO 13959 .
•
Once Hydrometer is clean, place the hydrometer onto a clean area.
