Input Water Quality
The quality of the input water is important as it influences the eectiveness
of the system and the safety of the water.
The input water should be from a potable cold-water source. Acuva purifiers
are eective for microbial (viruses, bacteria, and protozoa) disinfection and
a 5-micron filter is needed to remove particulate contamination from water.
Do not drink or use any water that is of unknown origin or that has not
undergone adequate treatment. A 5-micron carbon filter is recommended
and included for removal of bad taste and odor from the water.
Acuva’s recommended requirements for the input water are listed in  1.
UV transmittance >93%
Temperature 1 C < T < 27 C
Hardness < 120 (mg/L)
Turbidity < 1 NTU
Manganese < 0.05 mg/L
Tannins < 0.1 mg/L
Iron < 0.3 mg/L

the unit will power up, turn on the blue light
for 10 seconds, and the blue light will turn

soon as the faucet is opened, and water
starts to flow, a steady blue light on the unit
will indicate that the water purification is in
progress and that it is safe to drink water
from the device. When the faucet is closed,
the blue light will stay on for 4 seconds, then
goes out as the unit enters stand-by mode.

UV Device Smart Features
Installation instructions
In order to ensure that any water passing through the Arrow system is
eectively disinfected, the system includes smart features enabled by
a micro-controller. The Arrow system has self monitoring features and
disinfection cycle completion and self sanitation cycles.

Installation Guide
Acuva systems are designed for ease of installation. The Acuva Arrow is
designed for in-line or point of use installations, with a cold-water line.
1. Find a position with access to the cold-water line feeding your desired
water fixtures and faucets for the UV device and the pre-filter to be
mounted, that will allow space for the PE tubing to be connected without
needing to bend the tube to the point where they risk pinching or folding.
2. Mount the Din-Rail that will hold the UV device with two #10 wood
screws, and the mounting clips for the pre-filter, into position.
3. To install the ½” to 3/8”OD tube reducing union with shut-o valve fitting
to the cold-water line (or a ½”x ½” x 3/8” Tee with shut-o valve fitting
if used with a dedicated drinking water faucet only), assure that the cold-
water line is not under pressure or that water flow is cut o by an
upstream shuto valve. Expect some water to drain from the cold-water
line when cut, and cut the cold-water line with a tube cutter as straight
and cleanly as possible. To fit the ½” cold-water line to the ½” end(s)
of the fitting, push the tubes into the union as far as possible and pull the
tubing outwards to create a tight seal within the fitting.
4. Attach a length of the provided 3/8” PE tubing that will connect the fitting
to the pre-filter.

5. To install the pre-filter, wrap the threads of the 3/8”OD – ¼” MNPT
Adapters with at least 4-5 wraps of Teflon tape and screw these adapters
into the 2 female ends of the pre-filter, connect the 3/8” PE tube from the
union into the inlet side of the pre-filter, making sure that water will flow in
the proper direction as indicated on the filter, push the tube into the
adapter as far as possible and pull the tubing outwards to assure that the
adapter is properly sealed.
6. To install the UV device, wrap 4-5 layers of Teflon tape onto the threads
of the 3/8”OD-1/4”MNPT adapters and fasten these adapters into the inlet
and outlet female ends of the UV device.
7. Snap the pre-filter to its clips and mount the UV device to the din-rail.
8. Cut a length of 3/8”PE tubing that will connect the pre-filter to the UV
device inlet and connect the tubing by pushing the tube into the adapters
as far as possible and pulling the tubing outwards to ensure a tight seal.
9. To complete the installation (If used with a dedicated drinking water
faucet, proceed to section 3.2), cut a length of 3/8” tubing and connect
to UV device outlet adapter to the second ½”-3/8”OD tube reducing
union, and connect the reducing union to the cold-water line feeding your
desired faucets and fixtures.
1. Engage the spring-loaded mechanism by hooking the clip onto the
bottom edge of the din rail and adding 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.

Optional Smart-faucet Installation
If you have opted install the Acuva Smart Faucet with the provided 3/8” Tee
after the UV device (or with a ½”x ½” x 3/8” Tee with shut-o valve fitting
and 3/8”-1/4”OD Tube reducing union), use a short length of 3/8” tube to
connect the Tee with 3/8”-1/4”OD Tube reducing union (or for single faucet
applications, only the 3/8”-1/4”OD Tube reducing union), to connect a length
of ¼” PE tube to the drinking water faucet stem, and add the provided flow
restrictor to the ¼” line.
1. Drill a 3/4” hole into the counter top where the Smart Faucet will be
inserted.
2. Thread the faucet power cord 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.

Final Installation Steps
1. Connect the power supply cord to the UV chamber DC power plug.
2. Activate the cold-water pressure in the plumbing system.
3. Open the fitting valves
4. Open the downstream faucet(s) or water appliances. (When water is
flowing, the blue light on the device will come on steady which indicates
the water purification is in progress as seen in Figure 6)
5. Keep the faucet on to flush the system for 3-5 minutes to release all the
air pocket and bubbles and any loose granulated carbon form the pre-
filter and the water flows smoothly.
6. Once all the bubbles are released, turn o the faucet and the device will
automatically go into standby mode. At this point, the device is ready for
regular use.
Maintenance
The Acuva UV-LED Water Purification Systems are designed to give years
of trouble-free service. Using state-of-the-art long-life UV-LEDs, there are no
mercury bulbs to replace and dispose annually. However, there are some simple
tasks that should be performed to ensure continued trouble-free operation.
1. Check that none of the connectors are leaking annually.
2. Replace the inline 5-micron carbon filter every 2 years.
Regular Maintenance
Winterizing
WARNING
Failure to properly winterize the device before it is exposed to freezing
temperatures can lead to damage and water leakage.
To prevent freezing, pump a non-toxic antifreeze into the water system.
Open the point of use faucet connected to the Acuva device and
continue to pump non-toxic antifreeze until you see the antifreeze
coming out of the faucet. In the spring, remember to flush with fresh
water to clear the antifreeze before drinking.
