Ensure that you check the results of the test strip immediately. If the results are higher than 0.1
ppm (ANSI/AAMI 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 and hydrometer cylinder ready for use
Using STEP button step to the DRAIN Operation.
Press the RINSE CYCLE side START button.
PAUSE Indicator Light will turn off and the Drain Valve to OPEN and the Motor will turn ON.
Allow water to drain for 15 seconds.
Press PAUSE button, then quickly collect sample into hydrometer cylinder.
Once you have collected a sample, pour sample slowly over the chlorine test strip for 30
seconds.
Ensure that you check the results of the test strip immediately. If the results are higher than 0.1
ppm (ANSI/AAMI RD61: 2006) go to step 9.
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 less than 0.1 ppm
(RD61:2006) at the end of the Transfer and Drain Hose.
10. Once you have attained an acceptable bleach residual reading, place the drain hose on to the
Transfer Hose Holder, and press the RINSE CYCLE START button. Press the STEP MODE ON/OFF
button until the STEP MODE Indicator Light turns off. Allow the contents of the GranuFlo
Dissolution Unit II to drain and wait for the Rinse Cycle to complete. At this point the indicator
light should be at the RINSE CYCLE side CYCLE COMPLETE Operation.
11. Turn OFF the power to the GranuFlo Dissolution Unit II Tank and CLOSE the Main Transfer Ball
Valve near the filter housing. Then, connect the Transfer Hose to the GranuFlo Dissolution Unit II
Transfer Hose Holder.
12. Remove Filter Housing and drain all residual water from the Housing. Install new Filter and
tighten Filter Housing into place. See Figure 18.
Figure 18
13. Immediately after a successful DISSINFECTION CYCLE, make a batch of Dry Acid Product using
Section 7, pg 13. Leaving the GranuFlo Dissolution Unit II with only treated water or wetted with
only treated water leaves the Unit susceptible to bacterial growth.
8.4 UNIT FILTER AND BASE STAND PIPE FILTER MAINTENANCE
The 1 micron filter (FMCNA, P/N G84-202-12) should be changed under the following conditions:
1. The filter should be changed after mixing 6 batches.
2. When the GranuFlo Dissolution Unit II requires disinfection.
