Adjust the output of the Transfer Nozzle to a slow output flow.
•
Place the test strip under the flow for 30 seconds or the time interval recommended by the
manufacture of the test strip being used.
•
Close Transfer Nozzle Valve and press the PAUSE button (the PAUSE indicator light will
illuminate).
•
Ensure that you check the results of the test strip immediately. If the results are higher than 0.1
ppm (RD61: 2006) go to step 9.
•
Before proceeding to step 8, ensure the Drain Hose is secure to prevent the Hose from flailing
around during the DRAIN Operation.
8. Checking bleach residuals during DRAIN Operation from the Drain Hose.
•
Have chlorine test strip ready for use.
•
Using STEP button step to the DRAIN Operation.

Ensure that you check the results of the test strip immediately.
9. If residual bleach levels are higher than ANSI/AAMI Standard limit of <0.1 ppm (RD61: 2006), in any of
the two testing regions, initiate another complete RINSE CYCLE. After the RINSE CYCLE is complete,
start from section 8.3, #5, to check for residual bleach. Continue the RINSE CYCLE and test procedure
until bleach residuals are within ANSI/AAMI Standard limit of <0.1 ppm (RD61:2006) at the end of the
Transfer and Drain Hose.
10. Once you have attained an acceptable bleach residual reading, ensure the Mixing Tank is empty, turn
OFF power to the GranuFlo I Dissolution Unit, and CLOSE the Main Transfer Ball Valve near the Filter
Housing. Then, connect the Transfer Hose back onto the GranuFlo I Dissolution Unit Transfer Hose
Holder (See Diagram 2: GranuFlo I Dissolution Unit, pg 8).
11. Remove the Filter Housing and drain all residual water from the Housing. Install a new Filter and
tighten the Filter Housing into place (Figure 21).

GranuFlo I Dissolution Unit with only treated water or wetted with only treated water leaves the Unit
susceptible to bacterial growth.
