Product Overview
Congratulations on the purchase of your Arrow 5 UV-LED Water Purification
System. This is our high-performance 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, the Arrow 5 exposes harmful microorganisms
such as bacteria and other pathogens to the UV dose recommended by the
applicable standards.
The Arrow 5 water purification system is powered by 12V DC – either
directly or via 110V to 240V AC (using a power adapter). The Arrow 5
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
new purifier will deliver and please contact us if you have any questions.

Installation Guide Cont’d
Arrow 5 Installation
1. Find an under-counter position for the Arrow 5 device and pre-filter to be
mounted, allowing space for the tubing to be connected without needing
to bend the tube 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 screw and the filter clip
(item no. 4) for the pre-filter with the two remaining screws.
3. To install the ½” PEX-3/8” 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 3/8” tubing (item no. 2) that will connect the Tee to
the pre-filter (item no. 5). Insert the tube into the 3/8” 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 3/8” 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 Arrow 5 (item no. 6), mount it to the DIN-rail as seen in the
“Mounting the Unit” figure.
7. Cut a length of 3/8” tubing that will connect the pre-filter to the Arrow 5’s
inlet and push both ends of the tubing into place.
9. Cut a length of 3/8” tubing that will connect the UV device and the smart
faucet using a straight reducer adapter (item no. 10) and connect the
tubing to the desired water faucet (item no. 9) or appliance.

Mounting the Unit
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
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 indicator LED 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
WARNING
Do not use a wrench or pliers to tighten the plug or power jack as
this may cause damage to the device.

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.
Note: If there is an issue the indicator light will turn red or yellow and the trouble shooting
table in section 5 should be consulted
Maintenance
The Arrow 5 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 Arrow 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 unit 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.
