WARNINGS
1. Only use with potable water supplies (Water must be microbiologically safe).
2. Installation of RO system must comply with state and local laws and regulations.
3. Check for leaks after installation or service as system is reaching standard operating
pressure and temperature. Check for leaks periodically thereafter. A system may be
inadvertently moved or jarred while other items are moved under the sink. If a tting is ac-
cidentally loosened, a leak could result causing damage to your cabinet.
4. Do not let system freeze. Allow system to warm up to room temperature before installing.
It is best to be installed indoors with air temperature between 60° - 85° F.
5. Attach to cold water supply only.
6. A water-softening appliance is recommended if hardness of incoming water supply is over
10 grains of hardness to increase lter life.
7. Never drain RO tank completely without rst turning off the refrigerator icemaker.
8. Air-gap faucet may cause a slight noise at rst but noise should diminish in about a week.
If noise continues, adjusting drain clamp may help reduce noise. Also, install faucet so
air-gap faucet hole will drain into the sink if drain line gets plugged from obstruction in the
drain line.
9. Water containing iron in excess of 1ppm will require some pretreatment. Consult your local
water authority.
10. This reverse osmosis system contains a replaceable component critical to the efciency
of the system. Replacement of the reverse osmosis component should be with one of
identical specications, as dened by the manufacturer, to assure the same efciency and
contaminant reduction performance.
11. Failure to follow recommended service intervals or use of lters and parts other than those
recommended by the manufacturer may void warranty.
12. Drain RO tank completely at least twice a year. If daily use averages less than a gallon per
day, drain every two weeks. (See page 2 for Uses and Benets)
13. We recommend having all porcelain/enamel-coated sinks professionally drilled.
14. Sanitizing most RO systems on a yearly basis is important for reducing bacteria build-up.

INSTALLATION PROCEDURES
STEP 1 SYSTEM POSITION
The RO system needs both a water supply and access to a drain. The RO system is designed
to t under most sinks. The kitchen sink is the most common location for the RO install. Re-
move all system components from boxes and determine the location for placement of the Filter
Pac/RO module, tank, and faucet.
If you desire to hang the Filter Pac/RO module, use mounting screws, placing them to align
with holes in the bracket (make sure the cabinet wall is thick enough to support the Filter
Pac/RO module and that the mounting screws will not pierce through the wall). Hang
Filter Pac/RO module to assure sufcient space is allowed. Remove Filter Pac/RO module
from the wall for now and continue with install.
STEP 2 FAUCET INSTALLATION
1. Check for an extra hole in the sink You must drill a 1 ¼” hole for the faucet if the sink
does not have one. Determine Location of Faucet Hole Check underneath sink before
drilling. Make sure there are no obstructions. Drilling a Stainless Steel Sink Drill a 1 ¼”
hole with a hole-saw or hole punch for an air-gap faucet. Smooth out rough edges with a
le if necessary. A Porcelain/ Enamel-Coated Stainless or Cast Iron Sink The manu-
facturer recommends having this type of sink professionally drilled because of possibility of
chipping or cracking. If you are attempting to drill, use extreme caution. Obtain the proper
tools necessary to drill through the sink material. Follow the drill manufacturers instructions

STEP 3 EASY TAP ADAPTER INSTALLATION
Turn off cold water supply to the sink faucet and relieve pressure by opening the cold water
faucet. (Repair any existing plumbing sink leaks before continuing). Follow water supply from
the cold water supply valve, toward the sink faucet, until you reach a coupling nut (may be at
the base of the faucet). Unscrew the coupling nut. Place rubber washer into the plastic easy
tap faucet adapter and screw adapter onto location of coupling nut. Hand-tighten, then tighten
one more complete turn with a wrench. Re-attach the supply line to the adapter with the cou-
pling nut. Leave the cold water off.
CAUTION:
1. When tightening easy tap, make sure the tube to which you are attaching the easy tap is
not twisted. Use two wrenches to hold existing tube while tightening the easy tap adapter.
2. Examine existing cone shaped washer on water supply tube, adjust or replace if damaged
or worn (not included).
3. If self-piercing valve is used instead of easy tap, attach to hard copper tubing only. Do not
over tighten screws (see instructions on piercing valve package, not included).
NOTE: Push-In style ttings are designed for ease of use. Simply push the tubing in until it seats. Give a tug
on it to make sure it is secure. Insert red locking clip between tting and collar. If you need to remove the
tubing, remove the red locking clip, hold the locking ring collar against the tting while pulling out the tubing.
No inserts or nuts are used with the Push-In style ttings.
STEP 4 DRAIN SADDLE CLAMP INSTALLATION
Location of Drain Clamp
SINK WITH DISPOSAL
Select location to place drain saddle clamp. Best choice is the vertical pipe as near the sink as
possible making certain that the drain clamp is above the horizontal garbage disposal waste
pipe. When connecting the black drain tube to drain saddle clamp keep the tube run as straight

adapter
for your type of sink. Place an old towel under
the sink to catch any metal lings and to make
clean up easy. After drilling, clean up metal lings
quickly to avoid staining the porcelain.
2. Install Air-gap Faucet Pre-assemble faucet prior
to installing on the sink. Place the white spacer
onto faucet stem at side toward tubing and open
end upward. Slide spacer up the stem leaving
enough room for the thickness of the sink. Place
the washer onto the stem and thread on the 7/16”
nut up to the spacer. Attach the plastic 3/8” faucet
adapter tting to the base of the faucet stem (do
NOT over-tighten). See A in Figure 1 on the right.
3. Guide the (2) tubes and the faucet stem
through the hole on the sink until the faucet rests
on top of the sink. Center the faucet over the hole.
Position the faucet so the air-gap hole and the
faucet lever point toward the sink basin (in case
drain tube plugs causing water to spill out of the
air-gap hole). Insert the slotted washer under the
sink between the white spacer and the base of
the sink. Tighten the 7/16” nut securing the white
spacer tight against the sink. (see B in Figure)
Faucet may require repositioning before nal
tightening. Remove short packing tubing from top
of faucet and insert faucet spout by pushing spout
straight into the hole until it seats.

as possible and that there are no dips, loops, low spots or kinks. (See D in Figure 2 above).
Also, to reduce noise, assure that RO drain line enters the vertical pipe from a direction other
than the direction of entry of the garbage disposal pipe.
SINK WITHOUT DISPOSAL
Best choice is the vertical pipe about 4” above the water level in the trap.
To Install Drill a 3/8” hole through one side of the drainpipe. Align the hole in the drain clamp
with the hole in the drainpipe. Tighten down the drain clamp snuggly so it will not move on
drain pipe.
STEP 5 STORAGE TANK PREPARATION
1. Wrap the threads on top of the tank with 6 3wraps of Teon tape (do not use any type of
pipe compounds).
2. Screw tank ball valve onto the top of the tank (approximately 4 to 5 full turns - do NOT
over-tighten). Check for leaks once RO is pressurized and while tank is lling and again
when tank is full.
3. Tank is pre-charged with air pressure. Tank can be laid on its side if necessary (tank will
hold approximately 2 to 3 gallons of RO water depending on water pressure, tank position-
ing, and tank air pressure).
4. Tank pressure can be increased to improve water ow to the faucet or refrigerator. Air
pressure can only be tested when tank is completely empty of water. Air pressure of 5-PSI
minimum, 12-PSI maximum is recommended. The higher the air pressure the smaller the
volume of water the tank will hold. Pressure of 10-12 PSI may be necessary to feed a line
to the refrigerator. Over pressurizing may ruin the tank.
STEP 6 TUBING CONNECTIONS
I M P OR TA NT: Fitting manufacturer requires ttings to be re-checked after system reaches
full operating pressure and temperature, Re-tighten and secure as necessary.
1. ¼” White Supply Tube on Filter Pac/RO module Connect the supply (white) tube rmly
into the push-in port on the side of the easy tap adapter installed on the cold water supply
line. Optional If self-piercing valve is used, connect to valve using brass nut, tubing sup-
port, and ferrule, (not included).
2. ¼” red Drain Tube on FilterPac RO Module Air-Gap faucet system Use the coupler
from the parts bag to connect the ¼” red drain tube from the faucet to the red tube from
Filter Pac/RO Module. (See C in Figure 2 on page 6). Push rmly so tubes will not pull out
of coupler or leak.

3. 3/8” black Drain Tube from Faucet Connect this tube to the black 3/8” drain clamp. (See
D in Figure 2 on page 6). Tighten rmly so tube will not pull out of drain clamp. IMPOR-
TANT: Do not leave excessive slack in drain tubing. Shorten tubing so that it ows
directly to the drain with no dips, loops, low spots, or kinks.
4. Post Filter Connection to Faucet Depending on the model, connect the 3/8” blue tube
from either the outlet side of the post-lter bowl or the outlet tting from the 10” inline post-
lter cartridge to the 3/8” Push-In adapter tting on the RO faucet.
5. RO Tank Connection Depending on the model, connect the 3/8” blue tube from either the
tee of the inlet side of the post-lter bowl or the tee of the inlet side of the 10” inline post-
lter cartridge to the Push-In ball valve on top of the RO storage tank.
STEP 7 SYSTEM START-UP PROCEDURES
Turn your sink cold water supply valve to the on position while leaving the Filter Pac/RO mod-
ule and RO tank ball valves in the off position (horizontal, which is perpendicular to the valve).
Check for leaks and adjust as necessary.
1. Slowly turn Filter Pac/RO module ball valve to the on position (blue valve vertical, which is
in line with the valve). As water enters the lter bowls and makes its way through the lters
to the membrane element you will hear air escaping through the drain. This is normal.
Open RO faucet on the sink until the water starts coming out. (Water ow will only be a
trickle and may take up to 20 minutes before water starts to come out of the faucet spout
on some units). Shut RO faucet off and check for leaks and adjust as necessary.
2. Open the tank ball valve by turning handle a ¼ turn toward the tubing. Let tank ll for 4 to
6 hours (if you are changing lters, your tank may already be full, so you would not need
to wait). Then turn on RO faucet and drain tank completely, (approx. 5 minutes). Shut RO
faucet off, allow tank to rell, and drain again in 4 to 6 hours. The RO system is shipped
with a food grade preservative and must be ushed out prior to use. DO NOT DRINK THE
RO WATER UNTIL TANK HAS BEEN DRAINED TWICE.
3. Shut RO faucet off and let system ll again. RO water is now ready for use.
I M P OR TA NT: Check carefully for small leaks every few hours for the rst few days to assure
there are no leaks. It is wise on any RO system to inspect for leaks since the system sits
unseen underneath your sink and a small leak may not be detected without close inspection.
Check for leaks occasionally thereafter and make adjustments as necessary.
STEP 8 REFRIGERATOR ICEMAKER HOOK-UP
1. If there is not an ice-line from the RO to the refrigerator, you may choose to run an ice-line
so that your ice and water dispenser will have ltered water. If the distance from the refrig-
erator to the RO is more than 50’, we recommend 3/8” polypropylene or polyethylene tub-
ing for best results. DO NOT USE COPPER. (Be sure you have the recommended water
pressure to your icemaker according to the refrigerator manufacturer’s specications.) 3/8”
tubing, a supplemental storage tank, more RO air pressure, or different usage patterns,
may be required to supply adequate pressure!
2. Connect tube (not included) to appropriate refrigerator connection and to a plastic “T”
tting (not included) spliced into the 3/8” blue tube between the post lter and faucet. It
is recommended to install a ball valve on the tube to the refrigerator for service and start
up purposes. Keep ball valve off until start up procedures are completed and RO tank is
completely full after the second tank draining.
I M P OR TA NT: Never turn on icemaker before RO tank is full of water to avoid damaging re-
frigerator solenoid. If your refrigerator has a water dispenser in the door, upon initial start-up
you will need to depress the water supply lever 2 to 3 minutes before the water will dispense.
STEP 9 RECOMMENDED FILTER SERVICE LIFE
The types of lters listed below vary depending on RO system style. The manufacturer
provides very high capacity carbon lters and replacement intervals are based on our lters.

07\15 RO Manual 8
Other lters may not have the same capacity as original factory lters and may not last as long.
Water conditions vary greatly by region and can affect lter change intervals. For lter change
interval recommendations, follow the guidelines below. If in doubt, contact the manufacturer.
Sediment Pre-lter
These are the only lter(s) that you can visually inspect. They are white when new and will turn
dark with dirt and sediment when changing is necessary. A water softener will extend the life of
the lter(s). Inspect every 6 months or sooner in bad water conditions.
Carbon Pre-lter
These lters should be changed at least once a year. Changing these lters is necessary to
help insure membrane life and water quality. Use of high capacity carbon block lters is rec-
ommended. Granular carbon lters are not recommended because they release excessive
carbon nes at initial start-up, which can reduce the life of the membrane element.
RO Membrane
The RO membrane element is a replaceable component critical for effective reduction of TDS
(Total Dissolved Solids). The RO membrane should be changed when TDS rejection rate falls
below 75%. The rejection rate should be tested periodically to insure optimal performance.
The membrane typically lasts 2-5 years depending on inuent water quality and hardness. See
Performance Indicator information listed below. *
Carbon Post-lter/ Carbon MAP Filter
These lters need to be changed at least every 12 months to insure quality water. Do not wait
until taste is a problem.
*Performance indicator The RO system contains a replaceable treatment component criti-
cal for effective reduction of TDS (Total Dissolved Solids). The product water shall be tested
periodically to verify that the system is performing properly. Testing can be accomplished by
contacting the service company that installed your RO system or an authorized dealer. If a
service company is not available in your area a water sample may be sent to AmeriFlow™ for
a free TDS test of your RO water. Additionally a water quality monitor is available for purchase
from the manufacturer that will allow the product water to be tested at home.
To send water samples for TDS testing to the manufacturer do the following. Using 2 clean
containers put approximately ½ cup of tap water in one container and ½ cup of RO product
water in the other container. Send both samples to the manufacturer along with your contact
information.
To order replacement lters or locate a source in your area call the factory: AmeriFlow™ Water

STEP 10 FILTER CHANGE INSTRUCTIONS
1. Sediment and Carbon Turn Filter Pac/RO module ball valve to off position. Turn tank ball
valve off. Turn on RO faucet to help de-pressurize system. Unscrew lter bowls by turning
counter-clockwise. Remove old lters and discard. Clean lter bowls if needed in warm,
soapy water. Insert new lters into appropriate lter bowls. Make sure o-ring at top of lter
bowl is clean, lubricated and seated properly when tightening. If changing the post lter, do
so now following the same procedure as the pre-lters. Follow Step 7 - System Start-Up
Procedures. Check for leaks and adjust as necessary.
2. RO Membrane Turn RO tank and water supply off. Turn on RO faucet to help de-pres-
surize system. Disconnect white tube going into membrane housing. Unscrew end cap of
membrane housing. Have a towel and a bucket handy because some water will pour out.
Pull out old membrane and clean membrane housing if necessary with warm, soapy water.
Insert new membrane in the same direction as old membrane. Push rmly up to properly
seat RO membrane. Replace end cap and reconnect white tube to membrane housing.
Follow Step 7 - System Start Up Procedures. System should be sanitized each time mem-
brane is changed. (See Recommended Sanitizing Procedures on page 9). Test TDS (Total
Dissolved Solids) rejection rates and be sure the rates are over 75%. A TDS monitor is
optional on some models and included on others. If your unit did not come with a monitor,
you can order one or seek advice from a local water treatment service company. A new
membrane should
STEP 11 RECOMMENDED SANITIZING PROCEDURE
The manufacturer recommends having your system professionally sanitized once a year. The
best time to sanitize is when changing all the lters and/or when changing the membrane.
3. Drain all water from RO tank by turning on RO faucet until water stops owing. Follow Filter
Changing Procedures (assuring ball valve on tank and Filter Pac/RO module are in off po-
sition). Remove old pre-lters and membrane from housings. Remove the post-lter. On the
ET5000 a 3/8” union, and on the ET6000 a ¼”×3/8” reducer union, (not included), will be
necessary to reconnect the tubing together without the post-lter installed during sanitizing
procedures.
4. Carefully put 2 capfuls of household bleach into the empty lter bowl canisters. Re-install
lter bowls without lters. CAUTION: Be careful not to splash bleach on hands or surfaces.
5. Turn water supply on (open ball valve on tank and RO module) and let system ll for 4
minutes with tap water. Shut system off. Turn RO faucet on until water comes out and then
shut it off.Let entire system sit for about 30 minutes to sanitize. Then turn on RO faucet and
let system drain until empty. Turn off water supply valves and empty water in lter bowls.
Re-install lter bowls. Turn the water supply on again. Turn off faucet and let system rell
with tap water as before. Drain again. Install new lters following the Filter Change Instruc-
tions - Step 10. Follow System Start-Up Procedures Step - 7.
STEP 12 SERVICE AND MAINTENANCE RECOMMENDATIONS
All Reverse Osmosis systems require periodic maintenance to insure the continuation of water
quality. Test TDS rejection rates at least every 6 months. Changing lters is important for con-
tinuous good water quality. Filters need to be replaced at recommended intervals as old lters
may retain a considerable amount of debris and contaminants. Failure to change lters, use of
lower quality lters, or improper sanitization can dramatically reduce membrane life and water
quality. DO NOT WAIT UNTIL YOUR WATER TASTES BAD TO REPLACE YOUR FILTERS.
REMEMBER: Most contaminants do not have a foul taste except in extreme quantities. Testing
the check valve, ow restrictor, incoming water pressure, water hardness, and TDS levels peri-
odically are important to help extend membrane life and overall water quality. Your local water
professional can easily perform these tests. Failure to follow proper maintenance instructions,
use of lters or parts other than those recommended by the manufacturer, or use of an unau-
thorized service agent may void your warranty.
