WARNINGS

Form ETRO 1/06 Page 5 of 16
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 fitting is accidentally 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 filter life.
7) Never drain RO tank completely without first turning off the refrigerator icemaker.
8) Air-gap faucet may cause a slight noise at first 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 efficiency of the system.
Replacement of the reverse osmosis component should be with one of identical specifications, as defined by the
manufacturer, to assure the same efficiency and contaminant reduction performance.
11) Failure to follow recommended service intervals or use of filters 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 variety of uses)
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 –POSITION SYSTEM
A. The RO system needs both a water supply and access to a drain. The RO system is designed to fit under most
sinks. The kitchen sink is the most common location for the RO install. Remove 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 sufficient space is allowed. Remove Filter
Pac/RO module from the wall for now and continue with install.
STEP 2 - INSTALL RO FAUCET
A. 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.

Form ETRO 1/06 Page 7 of 16
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 file if necessary.
A Porcelain/Enamel-Coated Stainless or Cast Iron Sink. The manufacturer 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 for your type of sink. Place an old towel under the sink to catch any metal filings and
to make clean up easy. After drilling, clean up metal filings quickly to avoid staining the porcelain.
B. Install Air-gap Faucet. Pre-assemble faucet prior
to installing on the sink. Place the white spacer
onto faucet stem flat 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
9/16” nut up to the spacer. Attach the plastic 3/8”
faucet adapter fitting to the base of the faucet
stem (Do not over-tighten). (See A in figure on
the right).
C. 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 9/16” nut securing the white
spacer tight against the sink. (See B in figure on
the right). Faucet may require repositioning
before final tightening. Remove short packing
tubing from top of faucet and insert faucet spout
by pushing spout straight into the hole until it
seats.
STEP 3 - INSTALL EASY TAP ADAPTER
A. 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 coupling 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.

Form ETRO 1/06 Page 8 of 16
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).
Fittings Note: “Push-In Quick-Connect” style fittings 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 fitting and collar. If you need to remove
the tubing, remove the red locking clip, hold the locking ring collar against the fitting while pulling out the tubing. No
inserts or nuts are used with the push-in style fittings.
STEP 4 –INSTALL DRAIN CLAMP
A. Location of Drain Clamp
1. 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 as possible and that there are no dips, loops, low spots or kinks. (See D in
figure below). 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.
Or
2. Sink Without Disposal - Best choice is the vertical pipe about 4” above the water level in the trap.
B. 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 drainpipe.
STEP 5 –PREPARE STORAGE TANK
A. Wrap the threads on top of the tank with 6 wraps of Teflon tape (do not use any type of pipe compounds).
B. 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 filling and again when tank is full.
C. 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 positioning, and tank air pressure).

Form ETRO 1/06 Page 9 of 16
D. Tank pressure can be increased to improve water flow 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 –CONNECT TUBES
IMPORTANT: Fitting manufacturer requires fittings to be re-checked after system reaches full operating
pressure and temperature, Re-tighten and secure as necessary.
It is not recommended to shorten the length of any tubes during installation (except black or red 3/8” drain tube on air
gap faucet). This will make future servicing easier.
A. ¼” White Supply Tube on Filter Pac/RO module - Connect the supply (white) tube firmly 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 support, and ferrule, (not included).
B. ¼” Red Drain Tube on Filter Pac/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
above). Push firmly so tubes will not pull out of coupler or leak.
C. 3/8” Black Drain Tube from Faucet - Connect this tube to the black 3/8” drain clamp. (See D in figure above).
Tighten firmly so tube will not pull out of drain clamp. . Important: Do not leave excessive slack in drain
tubing. Shorten tubing so that it flows directly to the drain with no dips, loops, low spots, or kinks.
D. Post Filter Connection to Faucet –Depending on the model, connect the 3/8” blue tube from either the outlet
side of the post-filter bowl or the outlet fitting from the 10” inline post-filter cartridge to the 3/8” push-in
adapter fitting on the RO faucet.
E. RO Tank Connection –Depending on the model, connect the 3/8” blue tube from either the tee of the inlet side
of the post-filter bowl or the tee of the inlet side of the 10” inline post-filter 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 module and RO tank ball valves
in the off position (horizontal, which is perpendicular to the valve). Check for leaks and adjust as necessary.
A. 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 filter bowls and makes its way through the filters 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
flow 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.
B. Open the tank ball valve by turning handle a ¼ turn toward the tubing. Let tank fill for 4 to 6 hours (if you are
changing filters, 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 refill, and drain again in 4 to 6
hours. The
RO system is shipped with a food grade preservative and must be flushed out prior to use. DO NOT DRINK
THE RO WATER UNTIL TANK HAS BEEN DRAINED TWICE.
C. Shut RO faucet off and let system fill again. RO water is now ready for use.

Form ETRO 1/06 Page 10 of 16
IMPORTANT: Check carefully for small leaks every few hours for the first 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 HOOK UP
A. 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 filtered water. If the distance from the refrigerator to the RO is more than 50’, we
recommend 3/8” polypropylene or polyethylene tubing for best results. DO NOT USE COPPER. (Be sure you
have the recommended water pressure to your icemaker according to the refrigerator manufacturer’s
specifications.) 3/8” tubing, a supplemental storage tank, more RO air pressure, or different usage patterns, may
be required to supply adequate pressure!
D. Connect tube (not included) to appropriate refrigerator connection and to a plastic “T” fitting (not included)
spliced into the 3/8” blue tube between the post filter 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.
IMPORTANT: Never turn on icemaker before RO tank is full of water to avoid damaging refrigerator 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 filters listed below vary depending on RO system style. The manufacturer provides very high capacity carbon
filters and replacement intervals are based on our filters. Other filters may not have the same capacity as original factory
filters and may not last as long. Water conditions vary greatly by region and can affect filter change intervals. For filter
change interval recommendations, follow the guidelines below. If in doubt, contact the manufacturer.
A. Sediment Pre-filter - These are the only filter(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 filter(s).
Inspect every 6 months or sooner in bad water conditions.
B. Carbon Pre-filter - These filters should be changed at least once a year. Changing these filters is necessary to
help insure membrane life and water quality. Use of high capacity carbon block filters is recommended. Granular
carbon filters are not recommended because they release excessive carbon fines at initial start-up, which can
reduce the life of the membrane element.
C. 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 influent water quality and hardness. See performance indicator information listed below. *
D. Carbon Post-filter/ Carbon MAP Filter - These filters need to be changed at least every 12 months to insure
quality water. Do not wait until taste is a problem.
E. Biobrite UV Cartridge –The UV cartridge should be changed once a year. Warning: Never look directly at the
UV bulb while it is on! May cause serious eye damage! Always unplug UV unit before servicing.
* Performance indicator. The RO system contains a replaceable treatment component critical 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.

Form ETRO 1/06 Page 11 of 16
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 filters or locate a source in your area call the factory: AmeriFlow Water Systems Inc. 602-275-4188.

STEP 10 - FILTER CHANGING PROCEDURES
A. 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 filter bowls by turning counter-clockwise. Remove old filters
and discard. Clean filter bowls if needed in warm, soapy water. Insert new filters into appropriate filter bowls.
Make sure o-ring at top of filter bowl is clean, lubricated and seated properly when tightening. If changing the
post filter, do so now following the same procedure as the pre-filters. Follow Step 7 - Start Up Procedures.
Check for leaks and adjust as necessary.
B. RO Membrane - Turn RO tank and water supply off. Turn on RO faucet to help de-pressurize 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 firmly 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 membrane is changed. (See Recommended
Sanitizing Procedures). 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 perform
between 90-98%. Check for leaks and adjust as necessary.
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 filters and/or when changing the membrane.
A. Drain all water from RO tank by turning on RO faucet until water stops flowing. Follow Filter Changing
Procedures (assuring ball valve on tank and Filter Pac/RO module are in off position). Remove old pre-filters and
membrane from housings. Remove the post-filter. On the ET5000 a 3/8” union, and on the ET6000 a ¼” X 3/8”
reducer union, (not included), will be necessary to reconnect the tubing together without the post-filter installed
during sanitizing procedures.
B. Carefully put 2 capfuls of household bleach into the empty filter bowl canisters. Re-install filter bowls without
filters. CAUTION: Be careful not to splash bleach on hands or surfaces.
C. Turn water supply on (open ball valve on tank and RO module) and let system fill for 4 minutes with tap water.
Shut system off. Turn RO faucet on until water comes out and then shut it off.
D. 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 filter bowls. Re-install filter bowls. Turn the water supply on

Form ETRO 1/06 Page 12 of 16
again. Turn off faucet and let system refill with tap water as before. Drain again. Install new filters following the
Filter Changing Procedures –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 filters is important for continuous good water quality. Filters need to be
replaced at recommended intervals as old filters may retain a considerable amount of debris and contaminants. Failure
to change filters, use of lower quality filters, 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, flow restrictor, incoming water pressure,
water hardness, and TDS levels periodically 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 filters or
parts other than those recommended by the manufacturer, or use of an unauthorized service agent may void your
warranty.
