Step E – Clean the filter housings (bowls)
with a mild soap solution and
rinse with water . Check O-rings
and lubricate with water soluble
lubricant. KY Jelly ® , canola oil
or other water based lubricants
may be used . Petroleum
based lubricants (such as
Vaseline ® ) must not be used.
Caution: Before re-installing the filter bowls back on to the sys-
tem, check O-rings to make sure they are still in place.
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 & plastic 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™ counterclockwise .
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
Order filter by calling Watts at 1-800-224-1299
Item Needed: EDP# 7100110
Includes:
• (1) Sediment Filter • (1) Carbon Block Filter
Step A – Turn off the incoming water supply to the RO by turning the
knob on the Adapt-A-Valve™ clockwise until it stops .
Step B – Open the RO Faucet and allow water to drain from the tank
until it is completely empty .
Note: Water may be saved in a container for drinking or to rinse
system parts.
Step C – Let system sit for 10 to 15
minutes after the tank is empty
to let the system depressurize
before attempting to remove
filter housings .
Step D – For more leverage you may
leave the RO module attached
to wall of cabinet . If you are
unable to access the module
while it is mounted, remove it
prior to changing filters . Start-
ing with the closest housing
(Stage 1), remove it by turning
it clockwise (left), empty water,
then discard filter . Continue on
to the 2nd housing (Stage 2)
and 3rd housing (Stage 3) .
Note: If you own a 4-Stage system, it will not have the third
stage. A 4-Stage system has two vertical housings instead of
three.
Annual Maintenance
Order filter by calling Watts at 1-800-224-1299
Item Needed: # 7100115
1/2 cup of hydrogen peroxide or household bleach .
Includes:
• (1) Sediment Filter • (1) Membrane
• (1) Carbon Block Filters • (1) Final Inline Filter
Note: Sanitizing of unit is recommended.
Step A – Perform steps A through E in the Six Month System Main-
tenance .
Note: If not sanitizing the system skip to step H.
Step B – Remove the RO membrane from its housing and rest in a
clean sanitary place . (Refer to “Membrane Replacement”
section on Page 9 for directions on removing the mem-
brane) . Replace cap onto empty membrane housing and
re-connect green tubing .
Step C – Leaving the filters out, replace Stage 1 and 2 empty filter
housings (hand tight) onto unit . Measure & pour either 1 ⁄
2
cup of hydrogen peroxide or common household bleach
into the 1st filter housing (Stage 1) and hand tighten onto
unit .
Step D – With the RO faucet in the closed position turn on the
incoming water supply to the system by turning the Adapt-
A-Valve™ counterclockwise . 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 .
Step E – Turn off the incoming water supply to the system by turning
the Adapt-A-Valve™ clockwise until it stops. Keep the RO
faucet open until the storage tank is completely drained .
Step F – Open the membrane housing and re-install the RO mem-
brane while making sure not to kink the O-rings . (Refer to
“Membrane Replacement” section on Page 9 for directions
on installing the membrane) . Tighten the cap back on the
housing and reconnect green tubing .
Step G – Remove filter housings Stage 1 and 2 and empty of water .
Caution: Before re-installing the filter bowls back on to the
system , check O-rings to make sure they are still in place and
lubricate with water soluble lubricant.
Step H – Insert the 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 I – Insert the new Carbon Block filter (White End Caps) into the
2nd housing and re-install housing .
Do not over-tighten filter housing, overtightening may damage
O-ring(s), cause water leaks, or affect system performance.
Step J – The final in-line filter is located on the blue tube between
the storage tank and the RO faucet . Remove it by loosen-
ing the compression fittings on both ends of the filter and
replace with new filter . (Discard used final filter after sanitiz-
ing) .
Note: The arrow on the final filter must be pointing towards the
RO faucet / away from the RO storage tank.
This is a good time to check the air pressure in your storage
tank. For instructions please see Page 9.
Step K – Follow Steps H through J in the Six Month System Mainte-
nance (Page 8) for startup directions .
