the disinfect tank.
7. Connect the drain line (red QD) extension and connect the female portion to the

1. Verify that the dialyze/flush valve is in the DIALYZE position.
2. Turn the RO ON and circulate the solution through the system for five minutes.
After three minutes of circulation, test the product line for the presence of
disinfectant. Test by performing the following steps. If test results are
negative, continue circulating until a positive test is achieved.
a. Close the product valve.
b. Remove product line from tank.
c. Hold line over sample container and slowly open the product valve.
d. Test solution with a “gross” presence disinfectant test strip.
e. If positive, close the product valve, return line to tank, and open product
valve.
WARNING:
If a positive PRESENCE test result is not achieved, continue to recirculate for an
additional 3-5 minutes, then perform presence test again. Recirculate and re-test
as necessary until a positive test is obtained.
CAUTION:
Check that there is waste flow within 10 seconds. If not, turn RO OFF and verify
that the disinfect line is connected properly.
CAUTION:
DO NOT ALLOW PUMP TO RUN DRY. Damage will occur if pump is run
dry.
CAUTION:
Do not allow air or foam to be drawn up into the RO unit, as this will damage the
pump.
CAUTION:
Do not allow the solution temperature to climb above 25°C during this step.
Failure to control temperature will result in rapid deterioration of the membrane,
resulting in poor rejection.
