Annual Maintenance:

NOTE: Sanitizing of unit is recommended.

1. Perform steps 1 through 5 in the Six Month System Maintenance.

NOTE: If not sanitizing the system skip to step 2 - 6.

2. Remove the RO membrane from the housing and rest in a clean sanitary place. (Refer

to Membrane Replacement section for directions on removing the membrane).

Replace cap onto empty membrane housing and re-connect tubing.

3. Remove the filters out from the two vertical filter housings. Measure and pour either ½ cup

of hydrogen peroxide or 2 table spoons of common household bleach into the 1st filter

housing and re-attach the 2 empty filter housings onto unit with the supplied wrench.

4. With the RO Faucet in the closed position turn on the incoming water supply to the

system by turning the inlet valve counter clockwise. Wait 1 minute for the unit to pressurize.

Turn on the RO Faucet and let the water run for 30 seconds. Turn off the RO faucet and let

the unit rest for 2 minutes. Finally, open the RO faucet and let the water run for 5 more

minutes.

5. Turn off the incoming water supply to the system by turning the inlet valve clockwise until it

stops. Keep the RO faucet open until the storage tank is completely drained.

6. Open the membrane housing and re-install the RO membrane while making sure not to

kink the O-rings. (Refer to Membrane Replacement Section).

For Model VRO-3U:

1. Remove filter housings at stages 1 and 3 and empty the water.
