Rinse Cycle - The RINSE cycle has four Operations- FILL, RECIRCULATE, DRAIN and CYCLE COMPLETE. An

indicator LED will illuminate on the control panel to highlight which operation is currently in process during
the cycle.
Dissolution Cycle - The DISSOLUTION cycle has eight Operations- FILL, ADD GRANULES, MIX, DEAERATION,

FINAL FILL, HOMOGENIZE, Transfer and CYCLE COMPLETE. An indicator light will illuminate on the control
panel to highlight which operation is currently in process during the cycle.
Time Remaining- Once the Dissolution cycle or Rinse cycle is initiated, the time remaining will be displayed

until the entire cycle is completed.
Power On- An indicator light will illuminate to alert the operator that the Dissolution Unit is powered on.

CFU/mL- In microbiology, colony-forming unit (CFU or cfu) is a measure of viable bacterial or fungal

numbers. Unlike direct microscopic counts where all cells, dead and living, are counted, CFU measures
viable cells. For convenience the results are given as CFU/mL (colony-forming units per milliliter) for liquids,
and CFU/g (colony-forming units per gram) for solids
GFI (Ground Fault Indicator)- is an electrical wiring device that disconnects a circuit whenever it detects

that the electric current is not balanced between the energized conductor and the return neutral
conductor.
Hydrometer- an instrument used to measure the specific gravity (or relative density) of liquids; that is, the

ratio of the density of the liquid to the density of water.
IEC - International Electrotechnical Commission is an organization that sets international electrical and

electronics standards founded in 1906. It is made up of national committees from over 60 countries.
