Disinfection Procedure
NOTE:
If your RO system is equipped with a "submersible" high-pressure pump, the
pump/motor housing must be purged of all air during the start-up procedure. Turn on the
RO system and open the small valve on the top end of the pump/motor housing very
slowly to purge. Air should be heard escaping to the atmosphere. Close the valve when
water is seen flowing from this valve.
1. Turn off the RO unit power switch.
2. Label machine with appropriate warning signs such as “Do Not Use / Contains
Disinfectant” to prevent use of the RO until it is properly rinsed. Warning signs
should be placed at each use point if the loop piping is being disinfected.
3. Remove the RO product line from the Product Divert Valve Assembly (RO
Product Water connection) and connect to one of the upper connection ports on
the disinfect tank.
4. Prepare a 1:100 (1%) solution of Renalin
®
by mixing 13 ounces (400 milliliters)
of disinfectant concentrate to 10 gallons (38 Liters) of RO product water.
1. Use the RO unit to fill the disinfect tank with 10 gallons of product water and
turn off the RO.
2. Add 13 ounces (400 milliliters) of disinfectant concentrate to the disinfect
tank and mix well.
5. Connect a disinfect line hose between the Disinfect Inlet Valve on the RO and the
lower connection port on the disinfect tank.
6. Remove the RO waste line from drain and connect to an upper connection port on
the disinfect tank.
7. Open the Disinfect Inlet Valve and the Waste Flow Valve (counter clockwise) on
the RO unit. Direct Feed RO units will also require the loop return ball valve,
mounted vertically just prior to pump housing, to be closed during disinfection.
8. Loop piping disinfection will require the product line to be removed from the
disinfect tank and connected to the loop before proceeding. Direct Feed RO units
having the loop disinfected will require the loop return ball valve, mounted
vertically just prior to pump housing, to be open during disinfection.
