.
(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, the Drain Valve will 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, replace the drain hose, 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 Dry Acid Dissolution Unit 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 Dry Acid Dissolution Unit Tank and CLOSE the Main Transfer Ball Valve near
the filter housing. Then, connect the Transfer Hose to the Dissolution Unit 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 15.

13. Immediately after a successful DISSINFECTION CYCLE, make a batch of Dry Acid Product using Section 7,
page 14. Leaving the Dry Acid Dissolution with only treated water or wetted with only treated water
leaves the Unit susceptible to bacterial growth.
