Acuva Eco NX-Silver
OWNER’S PRODUCT MANUAL
Product Overview
Congratulations on your purchase of the Eco NX-Silver UV-LED water
purification system. This is our most compact and economical system that is
ideally suited for single faucet applications, ice-makers, and water fountain
upgrades. It fits easily under your sink in your home, cottage, RV and boat,
and provides safe drinking water that is convenient, low maintenance and
environmentally friendly.
Acuva’s water disinfection systems take water purification to the next
level of eciency and convenience by utilizing two well-established and
proven technologies: UVC disinfection and UVC-LEDs. Using patented
IntensebeamTM technology, Eco NX-Silver exposes harmful microorganisms
such as bacteria and other pathogens to the UV dose recommended by the
NSF (National Sanitation Foundation) standard.
The Eco NX-Silver water purification system is powered by 12V DC – either
directly or via 110V to 240V AC (using a power adapter). The Eco NX-Silver
operates on-demand, meaning its internal flow sensor will activate UV-LEDs
only when water is flowing through the system, improving energy eciency
and extending the life-time of the system.
Our mission is to provide universal access to safe drinking water and we are
proud that you have chosen our solution. Enjoy the peace of mind that your
Eco NX-Silver will deliver and please contact us if you have any questions.
The Eco NX-Silver is certified by IAPMO R&T to NSF/ANSI 55 Class “B” for the
supplemental bacterial treatment of disinfected public drinking water or other
drinking water that has been tested and deemed acceptable for human consumption
by the state or local health agency having jurisdiction. The system is only designed
to reduce normally occurring non-pathogenic nuisance microorganisms. Class B
systems are not intended for treatment of contaminated water. It is also certified by
IAPMO R&T to NSF/ANSI 372.

Installation Guide
1. Find an under-counter position for the Eco NX-Silver and pre-filter to be
mounted, allowing space for all tubing to be connected without needing
to bend to the point of pinching or folding.
2. Mount the DIN-rail (shown in the “Mounting the Unit” diagram) that will
support the device with two #10 wood screws and the filter clips (item
no. 3) for the pre-filter with the two remaining screws.
3. To install the ½” PEX-1/4” OD Tee & shuto valve (item no. 1) to the cold-
water line, ensure the cold-water line is not under pressure by turning o
the water and/or cutting the flow with an upstream valve. Expect some water
to drain from the cold-water line while cutting it. Insert the ½” cold-water
lines to the ½” female ends of the Tee, pushing the tubes into the Tee as
far as possible and pulling slightly to assure that the seal is secure.
4. Cut a length of the 1/4” tubing (item no. 2) that will connect the Tee to
the pre-filter (item no. 4). Insert the tube into the 1/4” OD female end
of the Tee, pushing the tube into the Tee as far as possible, then pulling
slightly to assure that the seal is secure.
5. Connect the 1/4” tube from the Tee into the inlet side of the pre-filter
while making sure that water will flow in the proper direction as indicated
on the filter. Push the tube into the filter as far as possible and pull
slightly to ensure it is properly sealed. Snap the pre-filter into its wall-
mounted clips.
6. To install the Eco NX-Silver (item no. 5), mount it to the DIN-rail as seen in
the “Mounting the Unit” figure.
7. Cut a length of 1/4” tubing that will connect the pre-filter to the Eco NX-
Silver’s inlet and push both ends of the tubing into place.
8. Cut a length of 1/4” tubing that will connect the device and the output
faucet or appliance, and install the flow restricter (item no. 6) at a point
along the tube that is convenient – noting the flow direction of the
restricter. Connect the tubing to the desired water faucet or appliance.
For faucet installation instructions, see Appendix A.

Installation Guide
1. Engage the spring-loaded mechanism of the mounting clips on the device
by hooking the clip onto the bottom edge of the DIN-rail and applying
slight pressure upwards.
2. As bottom portion engages, tilt the upper hook towards the DIN-rail.
3. Release the spring mechanism once the unit is mounted on the rail.
Mounting the Unit
Indicator Light
The Acuva logo lights up to indicate various modes of use.
No Light: The device is idle or no power is connected.
Blue Light: The device is active and sterilizing water.
Green Light: The device is undergoing its self-cleaning protocol. This 30
second protocol occurs at start up as well as after every 12 hours of idle
time and can be safely interrupted to dispense water.
Conditioning and Powering the Unit
1. Once the device is connected to the cold-water line, allow water to flow
through the system for 1-2 minutes until any bubbles are released from
the line. During this time, ensure all connections are tight and sealed.
2. Connect the DC power source or AC to DC power adapter to the device.
Hand-tighten the nut to the threaded jack to secure it.
3. If there is no water flow on powering up, the Acuva logo should glow
green for 30 seconds.
4. Turn on the faucet. The logo will glow blue which indicates the water
purification is in progress. If the smart faucet is installed, its base will glow
blue as well.
5. Turn o the faucet and the device will automatically go into standby mode.
Note: If there is a fault, the indicator light will turn red or yellow. Please consult the
Troubleshooting section.

Maintenance
The Eco NX-Silver is designed to give years of trouble-free use. Acuva
products use state-of-the-art UV-LEDs, meaning there are no mercury bulbs
to replace. However, there are some simple tasks that should be performed
to ensure continued operation.
1. Check monthly that none of the connectors are leaking.
2. Replace the in-line filter after winterization or as per the instructions on
the filter label.
Note: The small quartz windows inside the Eco unit do not reach high
temperatures to encourage mineral build-up (scaling) as with UV lamp
systems. As a result, no significant scaling or loss of performance due to
scaling over time is expected.
Regular Maintenance
Winterizing
WARNING
Frozen pipes mean cracked pipes. Failure to properly winterize the
Acuva Eco NX-Silver before it is exposed to freezing temperatures can
lead to damage and water leakage.
If the device is installed in a Recreational Vehicle (RV) ensure that the
RV is winterized as per its owner’s manual.

The unit is not powered
Verify that the unit is connected to power
and that the input voltage is within
specifications (11-16V).
The flow direction is

Ensure the inlet and outlet tubes are
connected to the respective fittings
marked “IN” and “OUT” on the device.
The flow rate is too low
The flow sensor inside the unit requires a
minimal water flow to activate the system
(approx. 0.3 Lpm). Ensure there is enough
water pressure in the line to reach this
flow. (12 PSI)
Red UV-LED fault
Unplug and plug in the device’s power
jack. If this fault persists, contact Acuva
for support.

Appendix A: Faucet Installation Instructions
1. Drill a 3/4” hole into the counter-top where the Smart Faucet will be
inserted.
2. Thread the faucet cable into the 3/4” hole and insert the faucet stem into
the hole.
3. Thread the faucet power cord through the plastic spacer under the
counter to ensure that the cord is not pinched against the counter when
the faucet is fastened into place, making sure that the spacer’s O-ring
seal is facing up to seal against the counter.
4. Add the plastic threaded fastener to the faucet stem and tighten the
fastener against the spacer to secure the faucet into place. Make sure
that the faucet is positioned properly as required before tightening the
fastener.
5. To connect the ¼” water line to the faucet stem, slip the hex nut onto the
tube, followed by the plastic ferrule and plastic tube support. Press the
tube end and ferrule to the bottom of the faucet stem and tighten the hex
nut by hand, then tighten the nut with a wrench while being careful not to
over-tighten.
