INTRODUCTION
You now own one of the most advanced home water ltration systems available
anywhere. The Aqua ✓Nano utilizes electropositive technology as part of a multi-
stage, high ow ltering system with limited pressure drop.
CC (Carbon Core) Cartridge
• Stage 1: Pre-Filtration - The Pre-Filter removes larger suspended solids to help
maximize the life of your NanoCeram® Cartridge.
• Stage 2: Electropositive Filtration - The second stage utilizes NanoCeram®
patented electropositive ltration media with ltration eciency and dirt-holding
capacity for particles as small as a nanometer or .001 micron.
• Stage 3: Advanced Carbon Block Technology - The third stage utilizes carbon
block technology and a special sorbent media to absorb and reduce chlorine, lead,
tastes and odors.
LP Cartridge (for Low Pressure situations)
• Stage 1: Pre-Filtration - The Pre-Filter removes larger suspended solids to help
maximize the life of your NanoCeram® Cartridge.
• Stage 2: Electropositive Filtration - The second stage utilizes NanoCeram®
patented electropositive ltration media with ltration eciency and dirt-holding
capacity for particles as small as a nanometer, or .001 micron.
The LP Cartridge comes without a carbon core and has twice as much NanoCeram®
for greater particulate holding capacity and very minimal ow restriction.
NOTE: The LP Cartridge WILL reduce chlorine, but it will NOT reduce dissolved lead.
The Aqua ✓ Nano is equipped with an electronic ow meter to advise you when to
reorder and to replace the NanoCeram® Cartridge.

FEATURES
• The Aqua ✓ Nano is designed for convenient counter-top use.
• It lters equally well while running either hot or cold water through the system.
• The Aqua ✓ Nano features a unique exible wand with spray and stream modes so
you can direct the ow of water where you want it. This makes it easier to ll bottles
and containers and to rinse vegetables and fruits.
• To ensure your supply of ltered water is uninterrupted, a visual ow meter indicates
when it is time to replace the NanoCeram® Cartridge.
• Both the NanoCeram® Cartridge and Pre-Filter Cartridge are easily replaced.
SAFETY PRECAUTIONS
∆ WARNING: Do not use with water that is microbiologically unsafe or of unknown
quality without adequate disinfection. Always replace the NanoCeram® lter cartridge
when the indicator light turns red.
• This lter is engineered to lter municipally treated water in the home.
• It is essential that you follow the operation and maintenance instructions enclosed
for proper performance. Failure to follow the Use and Care instructions will void the
warranty.
• Do not use with water over 57˚ C (135˚F) or below 4˚C (40˚F).
Capacity
The Aqua ✓Nano’s NanoCeram® Cartridge has a maximum capacity of one year or
11,355 liters (3,000 gallons), whichever occurs rst. The cartridge must be replaced
when the indicator light ashes red. Actual capacity will depend on the amount of
suspended solids and particles in your local water system. In certain water supplies,
tastes or odors may return or the ow may decrease prior to the rated capacity. In
these cases, the NanoCeram® Cartridge should be replaced more often.
Note: Contaminants or other substances removed or reduced by this water treatment
device are not necessarily in your water.

5. Place the Pre-Filter Cartridge, with label facing up, on top of the NanoCeram®
Cartridge; turn Cartridge clockwise slightly to lock.

6. Place the Inlet Assembly on top of the Pre-Filter Cartridge; rotate the Inlet Assembly
approximately 1/8 turn clockwise so that the tubing is in line with the Wand’s stem.
8. Thread the Diverter Valve onto the faucet;“hand–tighten”only. Do not over tighten
as it could damage the threads. (Note: If the diverter valve is not compatible with
your faucet, contact Rena Ware Customer Service for assistance.)
7. Using padded or locking pliers, remove the existing aerator from your faucet.
Remove the protective wrapping from the Diverter Valve assembly.

9. Place the Aqua ✓ Nano on a at counter surface near the sink. With the Wand
pointing outward over the sink, turn on the water and divert it through the lter
by turning the lever on the Diverter Valve 90°. Check for leaks. To stop the ow
through the lter, turn o the faucet or turn the lever in the opposite direction.
10. If needed, adjust the hose length between the Inlet Assembly and the Diverter
Valve to accommodate the cover. To make it longer, feed the tubing into the base
from the Diverter Valve end and pull it out at the inlet end.
To make it shorter, feed the tubing into the Base from the inlet end and pull it out
the diverter end. Do not pull the tubing too tightly over the lter cartridges as this
may restrict ow.
11. Place the cover on the base assembly.
12. Run water through the lter for 5 minutes to remove any small carbon particles and
expel excess air.
CHARGING THE SYSTEM: To improve the ow rate and to reduce the “run on” of
water after the faucet is turned o the system needs to be“charged”. Charging purges
trapped air from the system.
a. Run water through the system for about a minute to saturate the media.
Remove the pre-lter cartridge being careful to minimize the water that
spills onto the base unit.
b. Pour water into the top hole
to ll the NanoCeram® cartridge.
c. Re-install the pre-lter cartridge and again pour in water into the top hole of
the pre-lter cartridge until it is full.
Your Rena Ware Aqua ✓Nano Water Filter is now ready for you to enjoy!

Optional Stage Zero Filter
In areas where the amount of sediments in the water is very high,
the Pre-Filter cartridge can clog quicker than expected. The Stage
Zero external lter removes the larger particles to prevent this from
happening.
It can be easily back-ushed and replaced to allow your Aqua ✓ Nano
system to lter the very small things it was designed to remove and
let you go longer between Pre-Filter back-ushes and NanoCeram®
cartridge replacements.
OPERATION
• Switch between ltered and unltered water using the Diverter Valve lever.
• When the lever is pointing down, unltered water will come out of your regular
faucet.
• For ltered water, move the lever up 90°.
• Control the temperature with your regular faucet handle.
• The lter indicator will ash blue when the lter is functioning properly.
• The Wand will dispense water in either a steady stream or a spray. Rotate the collar
at the end of the Wand to switch between stream and spray modes.
NOTE: For best results, after sitting overnight or after several hours of non-use, run
water through the lter for 1 MINUTE before using.
Unltered Filtered
CARE/MAINTENANCE
Cleaning the Exterior of the Aqua ✓Nano
To clean the exterior of your faucet, lter cartridges, and base unit, use a clean,
damp cloth and mild, non-abrasive liquid soap. Do not use dishwashing soap. Rinse
thoroughly with warm water.
Note: Do not submerge the base unit or let stand in water. Excessive moisture
inside the unit will damage it and void the warranty.
Use of polish, detergents, abrasives, cleaners, organic solvents, or acid may cause
damage. USE OF OTHER THAN A DAMP SOFT CLOTH AND MILD LIQUID SOAP
WILL VOID YOUR WARRANTY.
Replacement Indicator Lights
Your Aqua ✓ Nano features a visual ow meter integrated into the base of the faucet.
When water is owing through your lter, LED (light emitting diode) lights will ash to
indicate the following:
• FILTERING The blue light indicates that the unit is functioning normally.
• REORDER The yellow warning light lets you know approximately 1,893 liters
(500 gallons) of life is left in the NanoCeram® Cartridge. Contact your Rena Ware
Consultant or Rena Ware Customer Service Center to order a replacement. The
blue FILTERING light also indicates that your lter is still working.
• REPLACE The red warning light indicates the NanoCeram® Cartridge’s eective
life has ended. The blue FILTERING light will not illuminate. Replace the
NanoCeram® Cartridge before continuing to use your lter.

Maintaining the Pre-Filter Cartridge
Back-Flushing
You should back-ush the Pre-Filter (up to three times) when a signicant reduction
in ow occurs. The disposable EM Media Insert should be replaced if back-ushing the
Pre-Filter fails to restore acceptable ow.
IMPORTANT: NEVER BACK-FLUSH THE NANOCERAM® CARTRIDGE.
Back-ushing the NanoCeram® Cartridge will damage its internal structure, causing
the lter to become ineective. Back-ushing can also contaminate the downstream
media of the NanoCeram® so that it will no longer lter properly.
Note: The back-ushing process requires two people.
1. Make sure the water is turned o.
2. Remove the back-ow adapter from the Inlet Assembly.
3. Remove the Inlet Assembly by turning it counterclockwise until it releases.
4. Remove the Pre-Filter Cartridge from the NanoCeram® Cartridge by turning it
counterclockwise until it releases.

➟
5. Invert the Pre-Filter cartridge and place the Back-Flow Adaptor on the outlet nipple
of the Pre-Filter.
6. Insert the outlet nipple of the Inlet Assembly into the other end of the Back-Flush
Adapter and keep pressure on it. Hold the inverted Pre-Filter over the sink, a
bucket or some other receptacle that can hold at least 2 gallons (7.5 liters).
7. Have a second person turn on the water. When the water is turned on, there will be
a small amount of back pressure forcing the Inlet Assembly out of the Back-Flush
Adapter so you must hold the Inlet Assembly, Back-Flush Adapter, and Pre-Filter
together to keep pressure on it and keep them from coming apart.
8. Allow the water to run for 5 minutes, shake the cartridge and tap it against the sink
until the ow rate has increased

Cleaning or Replacing the Media Insert
Clean the Media Insert regularly between replacements to extend the life of the
cartridge.
To clean:
1. Open the housing by turning the top counterclockwise.
2. Temporarily reconnect the inlet assembly to the lter base. Wash the reusable
housing and rinse o the media insert with water and dry. When washing the media
mild rubbing is acceptable. Do not scrub the exterior of the media too hard as it can
be damaged permanently. DO NOT USE SOAP.
3. After cleaning, insert the Media with the outlet nipple pointing down and the
punt up.

outlet nipple
NOTE: Back-ushing and rinsing will improve ow but will not restore the Pre-Filter
Cartridge to “like new” condition. The improvement will be less each time you back-
ush and rinse, until it is necessary to replace the Pre-Filter Cartridge to restore the
ow rate to an acceptable level.
Maintaining The NanoCeram® Cartridge
IMPORTANT: NEVER BACKFLUSH THE NANOCERAM® CARTRIDGE.
Back-ushing the NanoCeram® cartridge will damage its internal structure, causing
the lter to become ineective. Back-ushing can also contaminate the downstream
media of the NanoCeram® so that it will no longer lter properly.
Replacing the NanoCeram® Cartridge
NOTE: The Pre-Filter and the NanoCeram® are not necessarily replaced at the same
time. The led indicator lights refer only to the NanoCeram® cartridge. Replace it when
the ow meter’s red warning light ashes. It will also be time to replace the batteries.
1. Disconnect the NanoCeram® cartridge by removing the lter assembly and pre-lter
cartridge. Turn the NanoCeram® cartridge counterclockwise until it releases. Discard
the used cartridge.
4. Close the housing by turning the top clockwise until the arrows marked on the
housing are almost aligned and reinstall.

EN

2. Remove the battery compartment door in the bottom of the base by unscrewing
the two screws and by gently prying the door open using a at screwdriver.
3. Remove the old batteries, wait 20 seconds, and then replace with two new, high
quality, AA batteries with an expiration date of at least one year beyond the day of
installation. This will reset the ow meter to“0”and the LED lights will start ashing
again when water is owing through the lter.
4. Install a new cartridge and charge it. (See“SETUP” section).
5. Run water for 2 minutes to remove any carbon particles and expel trapped air.
TROUBLESHOOTING
Water is not coming out of the wand.
• Turn the diverter valve to the “on”position.
• Make sure the tubing is smooth and straight, without kinks.
Water leaks out of between lter cartridges or at the lter inlet assembly or lter
base.
• Separate the cartridges at the point of the leak. Each of the cartridges, and the
lter inlet, should have two o-rings on the raised outlet found on the bottom of
the cartridge. Check to ensure that the o-rings are in place and properly seated in
the grooves provided for them.
Water leaks from the tubing.
• Check the tubing for cuts or nicks.
Water continues to ow out of the wand after water is turned o.
• Water may continue to ow from the wand for a short time due to a build-up
of pressure within the lter. It will typically stop by itself. You may also turn the
diverter valve lever to the o position to activate your tap water faucet, which will
reduce water coming from the wand.
• Trapped air in the lter may force water out after the tap has been turned o.
To eliminate trapped air, follow the steps listed under the topic “CHARGING THE
SYSTEM”.
Lights on the base do not work.
• Make sure the batteries are properly installed. (See step 2 under“SETUP”. )
The electronic ow meter stops functioning.
Reset the meter by using the following procedure:
1. Remove the battery compartment door in the bottom of the base by unscrewing
the two screws and by gently prying the door open using a at screwdriver at the
point shown in the diagram. See“Replacing the NanoCeram® Cartridge”(step 2).
2. Remove the old batteries, wait 20 seconds, and then replace with two new high
quality AA batteries.
3. Replace the NanoCeram® lter cartridge, (see“Maintaining NanoCeram®
Cartridge”section). The unit will reset to its default settings.
