INTRODUCTION
Water is vital to maintaining good health. Water replenishes lost uids and helps to
regulate temperature, promote digestion and detoxify.
You now own one of the most advanced home water ltration systems available to
provide you and your family with fresh, great tasting, and economical ltered water
from your own kitchen tap.
HOW IT WORKS
The Aqua ✓Nano utilizes electropositive technology as part of a multistage, high ow
ltering system with limited pressure drop.
• Stage 1: Pre-Filtration - The Pre-Filter removes larger suspended solids to help
maximize the life of your Aqua√HD™ cartridge.
• Stage 2: Electropositive Filtration - The second stage utilizes Aqua√HD™
electropositive ltration media with nanolevel ltration eciency.
• Stage 3: High Flow Carbon Core - The open structure of the carbon core
eectively adsorbs chlorine, lead, tastes and odors with a minimal impact in the
water ow.
The Aqua ✓Nano is equipped with an electronic ow meter to advise you when to
reorder and to replace the media in your Aqua√HD™ Cartridge.
FEATURES
The Aqua ✓ Nano CTU-300 is designed for convenient counter-top use.
• 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 Media Insert in the Aqua√HD™ Cartridge.

SAFETY PRECAUTIONS
∆ WARNING: Do not use with water that is microbiologically unsafe or of unknown
quality without adequate disinfection. Always replace the Media Insert in the
Aqua√HD™ 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 38˚ C (100˚F) or below 4˚C (40˚F).
Capacity
The Aqua ✓Nano’s Aqua√HD™ has a maximum capacity of 11,355 liters (3,000 gallons).
The Aqua√HD™ Media Insert must be replaced when the indicator light ashes red.
For optimum performance we recommend replacing the Aqua√HD™ Media Insert at
least every 5 years even if the red light has not yet come on.
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 Aqua√HD™ Media Insert
should be replaced more often.
Note: The contaminants removed by the Aqua ✓Nano are not necessarily in your tap
water. The Aqua ✓Nano is intended for use only with municipally treated tap water.
Water of unknown origin can contain a variety of contaminants or substances that may
or may not be removed by the Aqua ✓Nano.

7. 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.
8. 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.
9. Run water through the lter for 2 minutes to remove any small carbon particles ,
expel excess air and saturate the Media.

10. Charge the system to improve the ow rate and to reduce the“run on”of water
after the faucet is turned o. Charging purges trapped air from the system:
a. Remove the Inlet Assembly from the top of the Pre-Filter and remove the Pre-
Filter cartridge being careful to minimize the water that spills onto the base
unit.
c. Re-install the Pre-Filter Cartridge and again pour in water into the top hole of the
Pre-Filter Cartridge until it is full, re-connect the Inlet Assembly and place the
Cover back on the base.
b. Pour water into the top hole
to ll the Aqua√HD™ Cartridge.

ACCESSORIES
STAGE ZERO FILTEROPTIONAL
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 Aqua√HD™
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 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.
• The lter indicator will ash blue when the lter is functioning properly.
• If the lter has not been used in 48 hours, ush it for 2 minutes before using.

CARE/MAINTENANCE
Cleaning the Exterior of the Aqua ✓Nano
To clean the exterior of your lter and cartridges, 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 CTU-300 features a visual ow meter integrated into the base of
the unit. 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
(300 gallons) of life is left in the Aqua√HD™ Media Insert. Contact your Rena
Ware Consultant or Rena Ware Customer Service Center to order a replacement
Aqua√HD™ Media Insert. The blue light also indicates that your lter is still
working.
• REPLACE The red warning light indicates that the eective life of the Aqua√HD™
Media Insert. has ended. The blue light will not illuminate. Replace the
Aqua√HD™ Media Insert before continuing to use your lter.

MAINTAINING THE PREFILTER
BACKFLUSHING THE PREFILTER
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 Aqua√HD™ CARTRIDGE.
Back-ushing the Aqua√HD™ Cartridge will damage its internal structure, causing
the lter to become ineective. Back-ushing can also contaminate the downstream
media of the Aqua√HD™ so that it will no longer lter properly.
Note: The back-ushing process requires two people.
1. Make sure the water is turned o and remove the cover.
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 Aqua√HD™ Cartridge by turning it
counterclockwise until it releases.

EN

5. Invert the Pre-Filter cartridge and place the Back-Flow Adaptor on the outlet nipple
of the Pre-Filter.
6. Over the sink insert the outlet nipple of the Inlet Assembly into the other end of
the Back-Flush Adapter and keep pressure on it.
7. Have a second person switch the diverter valve to the ltering position and turn on
the water. 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 PREFILTER MEDIA INSERT
We suggest wearing protective gloves when handling the cartridges
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 and remove the media by
grabbing the base of the housing with both hands and push the end cap of the
media forward
2. 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 punt up.

4. Close the housing by turning the top clockwise until the arrows marked on the
housing are almost aligned, reinstall and charge.
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 AQUA√HD™ MAIN FILTER
IMPORTANT: NEVER BACKFLUSH THE AQUA√HD™ CARTRIDGE.
Back-ushing the Aqua√HD™ cartridge will damage its internal structure, causing
the lter to become ineective. Back-ushing can also contaminate the downstream
media of the Aqua√HD™ so that it will no longer lter properly.
Replacing the Aqua√HD™ Media Insert
NOTE: The Media Inserts in the Pre-Filter and the Aqua√HD™ are not necessarily
replaced at the same time. The LED indicator lights refer only to the Media Insert in the
Aqua√HD™ cartridge. Replace it when the ow meter’s red warning light ashes.
For optimum performance we recommend replacing the Aqua√HD™ Media Insert at
least every 5 years even if the red light has not yet come on.
We suggest wearing protective gloves when handling the cartridges.
1. Disconnect the Aqua√HD™ cartridge by removing the Inlet Assembly and Pre-
Filter cartridge. Turn the Aqua√HD™ cartridge counterclockwise until it releases.
16

2. Open the housing by turning the top counterclockwise and remove the media by
pushing it forward and twisting until releases. Discard the used Media Insert.

3. Wash the reusable housing with mild soap and insert the new Aqua√HD™ media
with the punt up and close until the arrows marked on the housing are aligned
and reinstall.
4. Run water for 2 minutes to remove any carbon particles and expel trapped air and
charge it. (See“CHARGE THE SYSTEM”section).
Resetting the ow meter
When replacing the Aqua√HDTM Media Insert the ow meter has to be reset. Using a
pencil or pen point press the red button on the bottom of the base for 5 seconds and
wait for the indicator lights to re a ash sequence.

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 section “CHARGE THE
SYSTEM” - STEP 10.
Indicator Lights (LED) on the base do not work.
• Replace the old batteries with two new high quality AA batteries.
