Caution: Before re-installing the filter bowls back on to the sys-
tem, check O-rings to make sure they are still in place.
Do not over-tighten filter housing. May damage O-ring(s),
cause water leaks, or affect system performance.
Step F – Insert a new Sediment Filter
(cloth like appearance) into
the 1st filter housing which is
the one on the water inlet side
(green tubing from the Adapt-
A-Valve™) of the RO system
and re-install housing .
Step G – Insert the new Carbon Block
filter (White end caps & plas-
tic netting) into the second
and third filter bowls and
re-install housings .
Do not over-tighten filter housing, overtightening may damage
O-ring(s), cause water leaks, or affect system performance.
Step H –
Turn water supply on to the
unit by turning the knob on
the Adapt-A-Valve™ counter-

Step I – Open the RO faucet and leave
it open until water begins to
trickle out (It will come out
slowly) .
Step J – 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 production
capability of the membrane, local water temperature and
water pressure .
6-Month System Maintenance
