Filter Cartridge Replacement
• Filter cartridges for the SY-2650 will last about 500 gallons or six months
before they need to be replaced. Filter cartridge life varies depending on
usage, and/or water conditions. Changes in taste, color, and flow of the
water being filtered indicate that the cartridge should be replaced.
• Read all instructions before replacing filter cartridges.
WARNING: Use safety glasses and gloves when handling household bleach to
prevent bodily injury. Follow bleach manufacturer's instructions
when handling bleach.
1. Close water supply valve and open drinking water faucet to release pressure
from system.
2. Using the housing wrench, unscrew and remove bottom of filter housing.
Locate and remove large O-ring, wipe clean of lubricant, and set aside.
Repeat for second housing.
3. Discard used filter cartridges. Using a non-abrasive sponge or cloth, scrub
the bottom of filter housings, O-ring grooves, and caps with dish soap and
warm water. Rinse thoroughly. Fill bottom of each housing 1/3 full with
water. Add 1 teaspoon of household bleach and scrub to disinfect.
4. Lubricate O-rings with silicone grease. Insert each O-ring in groove and
press into place.
NOTE: This step is important to ensure a proper housing seal. Make certain
each O-ring is seated level in its groove or a leak may occur.
5. Screw bottom of housings with bleach water onto caps without filter car-
tridges and hand-tighten. DO NOT OVER-TIGHTEN.
6. Turn on water supply. Let faucet run for about 10 seconds, then turn off
faucet and let stand for 20-30 minutes.
7. Turn on faucet and allow bleach water to run out (about 3-5 minutes).
8. Turn off water supply to system and open faucet to release pressure.
Remove bottom of housings and empty of water.
9. Insert each filter cartridge into appropriate filter housing: SY-2650: D-250A
Cartridge Set: White with green end caps in left housing. Grey plastic
cartridge in right housing
10. Screw bottom of housings onto caps and hand-tighten. DO NOT OVER
TIGHTEN. Make certain cap standpipe slips into cartridge.
11. Open water supply valve and turn on drinking water faucet to release
pressure in system. Let faucet run for 5 minutes to remove trapped air
and carbon fines. Check system for leaks before leaving installation.
12. Press blue reset button.
NOTE:
• It is recommended that you run the tap at least 20 seconds prior to using
water for drinking or cooking purposes.
• Initially, filtered water may appear cloudy. If you set a glass of water on a
level surface, you should be able to watch the cloudiness disappear from
the bottom of the glass upwards This harmless cloudiness results from the
release of trapped air within the cartridge and will disappear within a few
weeks after installation.
Troubleshooting
Leaks:
…between cap and bottom of filter housing
Turn off water supply valve and turn on drinking water faucet to release pressure in
system. Remove bottom of housing. Clean O-ring and O-ring groove (located directly
beneath threads of housing). Lubricate O-ring with silicone grease and replace
securely into groove. Screw bottom of housing onto cap and hand-tighten. DO NOT
OVER-TIGHTEN. Turn on water supply valve and check for leaks.
…on system inlet/outlet connections
Turn off water supply valve and turn on drinking water faucet to release pressure in
system. Remove tubing from fitting (see NOTE under Step Six: Connecting the Supply
Adapter on p.3) and make sure end of tubing is cut squarely and free of scratches or
burrs. Reinsert tubing into quick-connect fittings, making sure to push securely until
tubing hits a hard stop. Turn on water supply valve and check for leaks.
…on supply adapter connection
Turn off water supply valve and turn on drinking water faucet to release pressure in
system. Loosen leaking threaded fitting on supply adapter or pull out leaking tubing
from fitting. Inspect to see if plastic tubing is scratched or supply adapter was properly
attached. If tubing is scratched, cut off 1/2-inch to 5/8-inch and reinstall per Step
Six: Connecting the Supply Adapter. Reconnect tubing or tighten compression nut with
fingers, then tighten nut snugly 1/2-turn with wrench. Turn on water supply valve and
check for leaks.
…on faucet/tubing connection
Turn off water supply valve and turn on drinking water faucet to release pressure in
system. Loosen and remove compression nut fitting on faucet stem. Make sure tubing
is inserted firmly into end of faucet stem, then retighten compression nut with fingers
until secure then tighten 1 turn with a wrench. Turn on water supply valve, then turn
off faucet to check for leaks.
NOTE: If leaks persist, or if there are other leaks on system, turn off water supply.

Low Water Flow
1. Check flow at faucet. The SY-2650 system should fill a gallon jug in approxi-
mately 2 minutes. Flow rates will vary with individual household water pressure.
2. Check filter cartridge installation. Make certain both filter cartridges are properly
oriented in filter housings (See Filter Cartridge Replacement on p. 5).
3. Check to be certain that the water supply valve is completely open (turn handle
on valve counter-clockwise as far as it will go).
4. Check flow through empty system. To do this, turn off water supply valve and turn
on drinkingwater faucet to release pressure in system. Then remove filter
cartridges from housings and screw housings back onto caps. Turn on faucet to
check flow through empty system. Flow should be about one to two gallons per
minute. If flow is less than 0.4 gallons per minute, call Technical Support at
1-800-645-5426.
5. If flow through empty system is adequate, place one filter cartridge in system at
a time and check flow to make sure cartridge is not clogged. Replace clogged
cartridge if necessary.
