Start Up Instructions
Step A– Turn on the incoming cold water at the angle stop valve .
Turn the knob on the Adapt-A-Valve™ by turning coun-
terclockwise . Check the system for leaks and tighten 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 – Open the RO faucet and leave it open until water begins to
trickle out . (It will come out slowly) .
Step C – 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: During the fill period, you may hear water trickling due to
the Reverse Osmosis Process.
Step D – After the Tank has filled, open the RO Faucet to flush the
tank completely to remove carbon particles from Final Fil-
ter . 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.
STEP 11
Blue Tube Connection (from system)
Step A – Position the RO storage tank in a desired location . You
may stand it upright or lay it on its side (using the black
plastic stand included) .
Step B– Locate the blue tube from the
RO module . Measure the tube
from the unit over to the stor-
age tank, and cut it to desired
length . Remove a brass nut,
plastic sleeve and brass insert
from the parts bag . To assem-
ble, place the brass nut on the
tube first, then the sleeve (small tapered end of sleeve must
point to the end of tube) and then insert the brass insert all
the way into the end of the tube . (See Picture)
Step C – Push the assembled blue
tube into the brass tank tee
until it stops . Slide brass nut
and plastic sleeve down until
you can thread nut onto the
tee . Use a wrench to securely
tighten the brass nut while
continuing to push the tube
into the tee .
STEP 12
Final Filter Installation
Step A – Remove the seal caps from
both ends of the final filter .
Step B – Thread the two white plastic
connectors into the final filter
and tighten with a wrench .
Note: Do not overtighten these con-
nectors as it may damage them or the
final filter.
Step C – Cut the blue tubing between
the RO faucet and the storage
tank at a desired location to
splice in the in-line final filter .
Step D – With directional flow arrow on
the filter pointing towards the
faucet, insert blue tubing from
faucet into the fitting on the
final filter (make sure tube is
pushed all the way into the fit-
ting) . Tighten with a 5 ⁄
8
" wrench
securely . Repeat this step to
connect the blue tube from the
tank into inlet side of the final
filter .
Note: A connection to a refrigerator / ice maker may be tee’d
into this blue tube and should be spliced in between the final
filter and the RO faucet.
