Use & Care Information
Water Requirements
The filtration system must be connected to a cold
water supply line providing 40-100 psi water pressure.
If psi is less than 40, a booster pump, (Part Number
4373525) will be needed.
Review the water application guideline chart
below to determine if your water meets the standards
necessary to use this water filtration system.
! WARNING
DO NOT use filtration system if water is
microbiologically unsafe or water quality
is unknown. Pretreat water that exceeds
limits for hardness, iron, manganese, and hydro­
gen sulfide.
Failure to follow these instructions could result
in personal injury.

Generai Tips
•For best performance of system, drain tank
completely once a week.
• To correct a leaky saddle valve, turn off cold water
supply and make sure saddle clamp screws are tight­
ened evenly and firmly. DO NOT overtighten, you
could crush the pipe. Then make sure the nut below
the saddle valve’s handle is tight. If not, tighten it with
a Vs" wrench.
• If the drain saddle leaks, it may not be tightly
clamped. Tighten the bolts on both sides evenly
and firmly.
• If the drain saddle elbow leaks, the connection may
be loose. Remove the elbow, wrap Teflon tape
around the threaded portion 2-4 times. Reinsert the
elbow into the drain saddle opening and tighten. DO
NOT overtighten.
•If the threaded portion of the brass compression nut that
is attached to the saddle valve leaks, turn off saddle
valve and remove the nut, wrap Teflon tape around
the threaded portion 2-4 times. Reconnect the nut.
• If a leak should occur at a push-in connector, the cause
is usually defective tubing. To correct the problem turn
off water supply to the RO system either at the saddle
valve or other existing water valve. Push in the grey
push-in connector and hold; then pull the tubing out of
the connector. Cut at least 'A" from the end of the tubing
using a plastic tubing cutter or a sharp razor knife. Make
sure the cut end is clean and blunt and that tubing is
round. Reinsert tubing as far as it will go. Turn on water
supply at valve.
• If a cartidge head leaks, it may have a misaligned,
pinched or damaged 0-ring. Shut off the saddle valve
and tank valve. Open the faucet until dripping stops (5
minutes minimum). Turn filter cartridge 'A turn to the left
and remove. Replace the 0-ring if it is misaligned,
pinched or damaged.
• If the spout leaks when faucet is closed, it is either
because of an obstructed or defective valve seat in the
faucet or because the tee-bar under the handle is not
adjusted correctly. To check for obstruction, turn and lift
valve spout to remove. Slide faucet handle forward over
spout hole. Unscrew tee-bar and slotted bushing from
faucet valve. Remove faucet valve and check for
obstruction. Replace valve. Part No. 4373522, if neces­
sary. To adjust the tee-bar, complete steps to check
obstruction and then raise the tee-bar.
• If there is no steady drip from the open faucet when
tank is drained, confirm that your cold water valve is
fully open. Confirm that the water saddle valve needle
pierced pipe and is fully open. Correct any leaks. Wait
for any trapped air to leave system. If the system was
connected to a refrigerator ice maker, the ice maker
valve may have been opened before installation was
completed. Turn the ice maker off and wait until faucet
drips.
•There are four things to check if the air gap opening
is leaking:
1. Blocked or improperly drilled drain line - clear drain
line, remove drain saddle and check for hole.
2. Air lock in gap outlet - blow air into air gap using a
short tube.
3. Excessive drain flow - disconnect red tubing from
faucet air gap inlet tube. Check that drain flow is less
than 175 ml (% cup) per minute. If not, replace red
tubing with tubing of proper length available from
your Whirlpool dealer.
4. Black drain tubing plugged - remove blockage in
black drain tubing. Replace tubing if necessary.

•If you experience too little or no drain flow, the red tub­
ing may be plugged or defective - replace red tubing
with tubing of proper length available from your
Whirlpool dealer. Confirm that the water saddle valve is
fully open. Check for obstructions in the faucet air gap
by removing the air gap and inspecting the flow path -
replace faucet if necessary. The Sediment or GAC car­
tridges may be clogged - replace if necessary.
• If you detect chlorine or unpleasant tastes or odors
at startup, there may still be some sanitizing agent in
the tank. Drain and fill tank two to three times.
• If you hear gurgling or dribbling sounds in the drain,
check that W black drain tubing from faucet slopes
downward to drain saddle. Angle drain piping so drain
water runs down side of pipe. Or, change location
of drain saddle to horizontal drain pipe or alternate
vertical drain pipe farther from trap. Important: Make
sure drain saddle is installed before (above) trap.
If a garbage disposal is present, the water may be
dripping off the edge of the baffle. Rotate the vertical
drain pipe above the baffle so the filtration system drain
hole enters the pipe on the opposite side.
• If the water has a bad taste after filter cartridges are
changed, the storage tank needs to be sanitized. Order
Tank Sanitizing Kit Part No. 4373527 and follow “How
to sanitize RO system" instructions.
How your RO water filtration
system works
Your RO water filtration system uses reverse osmosis
to help purify your water. When you use the system,
water is first filtered through a 5-micron filter to remove
particles 10 times smaller than your eye can see.
The water moves to the next cartridge and is forced
through granular activated carbon to remove chlorine and
taste-or-odor-causing compounds. The third
cartridge filters water through a reverse osmosis
membrane to reduce metals, salts and large organic
molecules when the faucet is turned on. Then the water
flows into the storage tank where it is ready to use. The
last (fourth) cartridge filters water from the tank again
through an activated carbon filter to remove any small
organic molecules and tastes that may still remain
in the water.
RO system production rate is 10.3 gallons per day at
50 PSI, 77°F and 715 mg/L NaCl.
Use this system only with water that has nitrate levels
limited to influent concentration of 30 mg/L or less. Use
the nitrate test kit provided with system to test nitrate
level of your water.
