Start Up Instructions
Warning: To prevent the possibility of electrical shock, clean up
any water on cabinet floor and dry all water from outside of RO
unit.
Step A– Turn on the incoming cold and hot water at the angle stop
valves by turning the knob on the Adapt-A-Valve™ coun-
terclockwise . Check the system for leaks and tighten push
to be further in any fittings as necessary . (Check frequently
over the next 24 hours to ensure no leaks are present) .
Note: If you have connected your RO system to a refrigerator /
ice maker, make sure the ice maker is off (do not allow water to
flow to the ice maker) until flushing is complete and the tank has
been allowed to fill completely. Connection from the RO to the
ice maker system should have an in-line valve installed before
the ice maker so it can easily be closed to prevent water flowing
to the ice maker during start up and periodic maintenance. Your
RO tank must be allowed to fill up fully in order for the ice maker
system to work properly.
Step B – Plug the 24 volt transformer power cord connector into the
RO wire harness connector (labeled Transformer) .
Step C – Plug the transformer into the electrical outlet under the
sink .
Step D – Open the RO faucet and leave it open until water begins to
trickle out (it will come out slowly) .
Step E – After water trickles out of the faucet, close the RO faucet
allowing the storage tank to fill with water . It may take 4 to
6 hours to fill the tank completely depending on the pro-
duction capability of the membrane, local water tempera-
ture and water pressure .
Note: Ensure Ball Valve on the RO storage tank is open.
Note: During the fill period, you may hear water trickling due to
the Reverse Osmosis Process.
Step F – After the Tank has filled, open the RO Faucet to flush the
tank completely to remove carbon particles from final filter .
You will know that the tank is empty when the flow rate
from the RO faucet is down to a trickle . Repeat this step
two more times . The fourth tank can be used for drinking .
Note: Flushing of the tank 3 times is only necessary during the
initial startup and after replacing the membrane.
Important: Your reverse osmosis system contains replaceable
treatment components that are critical for effective containment
reduction. Periodic inspection and following proper system
maintenance is critical for continued performance.
