Use and Care Manual

a.The tank should be empty. Check the air pre-charge pressure
with an accurate gauge (low pressure type 0-12 lbs.) The average
tank pressure should be 6–8 psi (when the tank is empty).
b.Fill the tank sanitizer feeder with the recommended disinfectant
dosage and connect the feeder to the water supply and RO
storage tank.
c.Turn on water supply and force water and disinfectant solution
into the RO storage tank. The storage tank should feel heavy
when filled.
d.The disinfectant solution should remain in the tank a minimum
of 10 minutes. If the tank has not been sanitized in over a year,
leave the solution in for 20 to 30 minutes. Turn off the water-
supply valve and the RO storage-tank valve. Disconnect the
sanitizer feeder and connect the RO storage tank to the RO unit
(the tank ball valve should remain closed).
10. Open the feed-water valve and open the RO faucet until water
flows freely from the spout. Close the RO faucet. Hold the
disinfectant solution in the RO system, including the tubing and
faucet, for a minimum of 10 minutes. Open the tank ball valve.
11. Shut off the feed-water valve and open the RO faucet. Let water
run out until the flow stops at the RO faucet.
12. Open the feed-water valve. Let water flow freely from the faucet
for three minutes. Shut off the water at the source water supply
with RO faucet open.
13. When the flow of water has stopped at the RO faucet, remove the
filter housing sumps and membrane housing from the RO system.
Replace the filters and membrane according to the service life.
14. Replace the housings on the RO system. Open the source-water
valve and allow the water to flow from the faucet.
Because some of the disinfectant may still be in the system,
the system should be flushed prior to using the water for
human consumption.
A maintenance record should be kept for the RO system,
including information about the replacement parts, when
service was performed, and by whom.
