4.4.2.2 Post Renalin® Disinfection Rinse Procedure
1. Remove the Disinfect Inlet Valve disinfection line from disinfect tank and
connect to drain.
2. Ensure that the water supply to the RO unit is on. Ensure Direct Feed RO units
have the loop return ball valve, mounted vertically just prior to the pump housing,
is in the open position, and loop flow is being returned to the unit.
3. Turn on the RO unit power switch and allow the RO to rinse for 10 minutes. RO
systems with the Disinfect Alarm Monitor and RO Status Monitor must have both
disinfect key switches in the off/normal operation position to continue rinse
operations.
4. Slowly open the Disinfect Inlet Valve and allow water to rinse to drain. A low
pump feed pressure condition may be created if this valve is opened too far.
5. Close the Disinfect Inlet Valve and disconnect drain hose.
6. Turn the power switch ON and OFF in alternating one minute cycles to rinse out
any trapped disinfectant in the RO unit. Repeat 3 times.
7. Continue to rinse for an additional 5 minutes. Open each use point in the loop if
the loop piping was disinfected.
8. Check the product effluent and each use point as applicable for the absence of
disinfectant. Continue rinse until absence of disinfectant is confirmed
9. Turn off the RO unit power switch when the absence of disinfectant is confirmed.
10. Reconnect the product line to the Product Divert Valve Assembly if unit was
disinfected separately from loop piping.
11. Remove the "Do Not Use/Contains Disinfectant" warning label(s).
