Press Dissolution START button, slightly open Transfer Nozzle Valve and
flush approximately 3.5 gallons.
•
Once the 3.5 gallons of solution have been flushed out of the transfer hose,
CLOSE the Transfer Nozzle.

Disposition the flushed solution according to clinic policies and procedures.
6. Fill the Hydrometer Cylinder:
•
Insert the Transfer Nozzle into the Hydrometer Cylinder.
•
Slowly OPEN the Transfer Nozzle Valve until solution starts to
slowly accumulate into the Hydrometer Cylinder. Allowing
solution to fill down the side of the beaker minimizes the
creation of bubbles within the solution (Figure 12, item B).

Fill the Hydrometer Cylinder approximately 2/3 rd full.
•
CLOSE Transfer Nozzle and then press PAUSE on the Display
Panel.
•
Place Transfer Nozzle onto a clean surface.
7. Make sure the solution you gathered does not have excessive
amount of bubbles. To release excess amount of bubbles from
the solution gently tap the Hydrometer Cylinder or gently swirl
the entire Hydrometer Cylinder until bubbles have been
released from the solution (Figure 13).
