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-
clockwise .
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# 7100113
Includes:
• (1) Sediment Filter • (2) Carbon Block Filters
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 con-
tainer 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 .
Starting 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) .
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 lubri-
cants (such as Vaseline ® ) must not be used.
Annual Maintenance
Order filter by calling Watts at 1-800-224-1299
Item Needed: EDP# 7100114
1/2 cup of hydrogen peroxide or household bleach .
Includes:
• (1) Sediment Filter • (1) Membrane
• (2) Carbon Block Filters • (1) Final Inline Filter
Note: Sanitizing of unit is recommended.
Step A – Perform Steps A through E in the 6-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 10 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 10 for direc-
tions 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.
Do not over-tighten filter housing. May damage O-ring(s),
cause water leaks, or affect system performance.
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 filters (White End Caps) into
the 2nd housing and 3rd housing, then re-install housings .
Step J – The Final In-line Filter is located on the blue tube between
the storage tank and the RO faucet . Remove it by loosening
the compression fittings on both ends of the filter and re-
place with new filter . (Discard used final filter after sanitizing) .
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 7.
Step K – Follow Steps H through J in the 6-Month System Mainte-
nance (Page 9) for startup directions .
