Safety Consideraons
Although your UV system has been manufactured to the highest safety standards, care
must be followed when operang and/or maintaining your system.
1. Before servicing the system, disconnect the power cord from the electrical outlet.
2. Energy given o by the UV lamp is harmful to your eyes and skin. NEVER look
directly at an illuminated UV lamp without adequate eye protecon and always
protect your skin from direct exposure to the UV light.
3. For complete disinfecon, use ONLY genuine replacement parts.
4. Do not operate the unit if it has any damaged or missing components.
5. To avoid possible electrical shock, use the unit only with a properly grounded
electrical outlet.
6. Never perform any maintenance to the system unless you are comfortable in
doing so. Contact the manufacturer for service instrucons if required.
7. Do not use this system for any purpose other than what it was intended for. Misuse
of this system could potenally cause harm to the user or others.
8. Your system is intended to be installed indoors and away from leaking plumbing.
DO NOT plug the unit in if the system or any of the components are wet.
9. The disinfecon system should be directly installed into a ground fault circuit
interrupter (GFCI). If the use of an extension cord is required, the cord must be
manufactured with a minimum of 16 gauge wire and care should be taken to avoid
potenal tripping hazards.
10. We recommend that a licensed plumber or cered technician install the system.

Before You Begin
The following will be needed for installing the UV system:
Tools
• Pipe cuer, hacksaw or other specialized tools required to cut into your exisng
plumbing (e.g. if you have PEX piping)
• Soldering tools (torch, ux, emery cloth and solder)
• Wrench (for ghtening ngs)
Other Materials
• Inlet/outlet connecons
• Teon™ tape
Water Quality Parameters
UV disinfecon is extremely eecve against microorganisms but only if the UV light
can pass through the water it needs to treat. This means that the quality of your water
is very important in order to ensure complete disinfecon.
Treated water should be tested for at the least the parameters listed below. If the
water exceeds the listed parameters Neo Pure strongly recommends that appropriate
pretreatment equipment be installed (equipment required will depend on parameters
being treated):
Hardness: <7 gpg (120 mg/L) – if hardness level is 7 gpg or slightly
below the quartz sleeve must be cleaned periodically in
order to ensure ecient UV penetraon; if above the
water must be soened.
Iron (Fe): <0.3 ppm (0.3 mg/L)
Manganese (Mn): <0.05 ppm (0.05 mg/L)
Turbidity: < 1 NTU
Tannins (organics): <0.1 ppm (0.1 mg/L)
UVT (transmiance): >85% (Please contact Neo Pure if water has a UVT that
is less than 80% for pre-treatment recommendaons)
You can have your water tested at a private analycal laboratory or by your local dealer.
It is always recommended to install pre-ltraon of at least 5 microns prior to a Neo
Pure UV disinfecon system.

System Sizing
All Neo Pure UV systems are rated for a specic ow rate in water that meets the
quality parameters on page 5. PLEASE NOTE that increasing the ow above this rang
or disinfecng water that does not meet the quality parameters will decrease the dose
and therefore compromise the microorganism inacvaon.
To determine ow rate follow these simple steps:
• Be sure no water is being used in the home. Open a faucet or tap nearest the
pressure system and run unl the well pump starts. Close the faucet and using a
second hand watch, record the length of me in seconds unl the pump stops. This
is known as the cycle me.
• Then using a container of known volume, preferably in US Gallons, open the faucet
or tap nearest the pressure system and measure the amount of water drawn o
unl the pump starts again. Depending on the size of the container used, it is
acceptable to turn the faucet on and o to empty the container. This measurement
is known as the draw down.
• To calculate the pressure system ow rate divide the draw down by the cycle me
and mulply that by 60.
• Draw Down__________÷ Cycle Time____________ x 60=__________Pumping
Rate in USGPM
Locaon
For Point of Entry (POE) systems, choose a locaon where the main cold water line
is accessible. Install the system aer other water treatment equipment (soener or
lters), but before any branches (See Figure 1). For Point of Use (POU) systems, install
the unit just before the faucet. Neo Pure recommends that a 5 micron lter be installed
before the UV system for a nal polishing step before the water is disinfected.
Figure 1. Recommended POE Installaon Locaon

To facilitate lamp removal, ensure there is enough space at the lamp connector end
to safely remove the UV lamp and/or quartz sleeve (See Figure 2). The controller will
require a ground fault circuit interrupter (GFCI or GFI) outlet and should be mounted
beside or above the reactor. PLEASE NOTE: All Neo Pure UV disinfecon systems are
intended for indoor use only as they should not be exposed to the elements.
Installaon
Step 1: The reactor can be installed either
horizontally or vercally using the clamps provided.
Vercal installaon is the preferred method with the
inlet at the boom (lamp connecon at the top) as
it allows any air that may be in the lines to be easily
purged from the system.
Step 2: The use of a by-pass assembly is
recommended as it will allow you to isolate the
UV reactor. This will allow for easier access in case
maintenance is required (See Figure 3).
Step 3: Use the supplied fasteners to mount the
UV reactor to wood or drywall. If mounng to an
alternate material you will need to purchase the
proper corresponding fasteners.
Step 4: For water supplies where the maximum ow
rate is unknown, a ow restrictor is recommended
so that the rated ow of your parcular Neo Pure
system is not exceeded. The ow restrictor should be
installed on the inlet port of the reactor.
Step 5: It is recommended to have a licensed
plumber connect the UV reactor to the water supply
and may be a requirement depending on where you
are located.

Step 6: Once the system has been plumbed in, gently
remove the quartz sleeve from its packaging being careful not
to touch the length with your hands. The use of coon gloves
is recommended for this procedure as oils from the hands can
leave residue on the sleeve and lamp which can ulmately
block the UV light from geng to the water.
Carefully slide the sleeve into the reactor unl you can feel
it hit the opposite end of the reactor. Align the sleeve so its
centered along the length of the reactor, then gently push it
in to lock it into the internal centering springs in the far side
of the reactor. CAUTION: Pushing too hard when the sleeve is
not aligned can damage the centering springs. Slide the o-ring
onto the sleeve unl it is bued up against the reactor.
Figure 4. Quartz
Sleeve Installaon
Step 7: Hand ghten the provided gland nut over the quartz sleeve onto the threaded
end of the reactor. It has a posive stop to prevent over-ghtening. A rm force may be
required to fully ghten the gland nut, but DO NOT USE TOOLS for this step. Insert the
provided stainless steel compression spring into the quartz sleeve. The spring works
with the lamp and lamp connector to create the proper lamp alignment. PLEASE NOTE:
DO NOT install a UV lamp inside the quartz sleeve without the sleeve spring in place.
Step 8: Install the UV sensor (“NP6” systems only). Align the at poron so it faces
the gland nut end and matches up with the half metal lip on the sensor port (see Figure
5). Insert the sensor so it is fully seated and hand ghten the sensor nut.
Figure 5. UV Sensor Installaon Figure 6. IEP Connecon
Step 9: The reactor is now ready for water ow. When all plumbing connecons
have been completed, slowly turn on the water supply and check for leaks. Make sure
the by-pass valves are funconing properly and that the water is owing through the
reactor. The most common leak is from the o-ring not making a proper seal on the
reactor. For new installaons, review steps 6 and 7. For older systems drain the reactor,
remove the o-ring, dry it and reapply silicon grease. Reinstall the o-ring ensuring that it
is properly sealed against the reactor and check again for leaks.
Step 10: Mount the controller to the wall so it is above or beside the reactor to ensure
that no moisture can deposit on any of the connecons (see Figure 1). Always mount

11|Page
the controller vercally. For monitored systems, insert the sensor connector into the
IEP port located on the right side of the controller (Figure 6). For the sensor to be
recognized by the controller, the controller power must be plugged in last. Do not plug
the controller power cord in before the last step.
Step 11: Always hold UV lamps by their ceramic ends, not by the lamp quartz. Remove
the lamp from its packaging. Again, the use of coon gloves is recommended. Remove
the lamp key from the lamp’s connector and set it aside for the next step. Be careful to
not touch the key’s exposed contacts. Insert the UV lamp into the reactor, being careful
not to drop it.
Step 12: Install the lamp key into the controller (units with the “NP5/6” designaon
(color screen) systems only). The key always comes packaged with the lamp and sits on
the connector. With the key removed from the lamp, orient it so the label is upright and
facing you. The key will plug into the lamp key port on the right side of the controller
(Figure 8).
Step 13: Plug the lamp connector into the lamp. Note the keying for proper alignment
(see Figure 7a, 7b). Insert the lamp connector into the gland nut and turn the connector
approximately ¼ turn to lock the connector to the gland nut as in Figure 9.
Figure 8. Lamp Key Installaon Figure 9. Lamp Connector
Step 14: Tighten the capve ground screw to the ground lug on the UV reactor to
ensure proper grounding.

Step 15: Your system is now ready to be plugged into the appropriate GFCI protected
outlet. Refer to the following System Disinfecon secon before any water is allowed
to ow through the system.
System Disinfecon
With a new installaon, or any me the UV system is shut down for service, without
power, or is inoperave for any other reason, the lines in the home or facility could be
contaminated. Use the following steps to fully disinfect the lines throughout the enre
home or facility.
Step 1: Check for and remove any “dead ends” in the lines throughout the home as
these can harbor bacteria. Plug in the UV system and wait unl it is ready for operaon.
Step 2: Remove the lter cartridge from the last sump and ll it with 1-2 cups of
household bleach (most are 5.25% chlorine). Replace the sump and slowly turn on the
water supply.
Step 3: At a water outlet, run the water unl bleach can be smelled. Repeat this for
all faucets, toilets, shower heads, refrigerators, outdoor taps, the washing machine,
dishwasher, etc. at the home or facility. Once nished, wait a minumum of 30 minutes
before connuing.
Step 4: Reinstall the lter cartridge into the sump and ush the chlorine soluon
by opening all faucets unl chlorine can no longer be detected. Your home has now
been completely disinfected with your Neo Pure UV system ready to inacvate any
microorganisms that enter the home.

Cleaning the Quartz Sleeve
Depending on the water quality, the quartz sleeve may require periodic cleaning. At a
minimum, the quartz sleeve should be cleaned on an annual basis. The following steps
outline a basic cleaning procedure.
Step 1: If a by-pass assembly is installed, shut the inlet valve o to prevent water ow
through the system. Otherwise, turn o main water inlet valve (and/or turn o the
water pump).
Step 2: Disconnect power cord of UV system from electrical outlet.
Step 3: Release water pressure by opening a downstream faucet and then close the
outlet shut-o valve (if one is installed). If there is no outlet shut-o valve, expect water
to drain from the system as the head pressure in the system will cause the water to
ow back down.
Step 4: Remove the capve ground screw from the ground lug on the UV reactor.
Step 5: Remove the lamp connector from the reactor (gland nut) by pushing the lamp
connector in and turning it ¼ turn counter-clockwise. Disconnect the lamp connector
from the lamp. CAUTION: the lamp may be hot!
Step 6: Being careful to touch only the ceramic ends, carefully remove the lamp out
of the reactor.
Step 7: Unscrew the gland nut from the reactor exposing the end of the quartz sleeve.
Step 8: Remove the quartz sleeve and o-ring by gently twisng and pulling the sleeve.
Step 9: Using a so, lint-free cloth or towel wipe the sleeve down using a commercial
scale cleaner (i.e. CLR® or LIME-A-WAY®). This removes scaling or iron deposits that
may be on the outside of the quartz sleeve. Be careful not to get any moisture or
liquids inside of the sleeve.
Step 10: Dry the sleeve with separate cloth.
Step 11: Replace the o-ring and slide the sleeve back into the reactor following steps 7
and 8 from the installaon secon of the manual.

14|Page
Cleaning the UV Sensor
Depending on the water quality, the UV sensor may require periodic cleaning. At a
minimum, the UV sensor should be cleaning on an annual basis. The following steps
outline a basic cleaning procedure.
Step 1: If a by-pass assembly is installed, shut the inlet valve o to prevent water ow
through the system. Otherwise, turn o main water inlet valve (and/or turn o the
water pump).
Step 2: Disconnect power cord of UV system from electrical outlet.
Step 3: Release water pressure by opening a downstream faucet and then close the
outlet shut-o valve (if one is installed). If there is no outlet shut-o valve, expect water
to drain from the system as the head pressure in the system will cause the water to
ow back down.
Step 4: Place something under the reactor to catch any water that may come out of
the reactor during the removal of the UV sensor.
Step 5: Unscrew (counterclockwise) sensor nut from the reactor and pull the sensor
slowly out of the sensor port.
Step 6: Holding the sensor in your hand wipe the at poron (sensor face) of the
sensor with isopropyl alcohol using a clean lint-free cloth.
Step 7: Replace sensor following step 9 from the installaon secon of the manual.
Operaon
Neo Pure systems come with a feature laden controller that incorporates both the lamp
driver (ballast) and control features in one water-ght case. Four main controllers are
available for the Neo Pure systems (depending on your model). All four models feature
a power factor corrected, constant current lamp driver with a universal power input.
Please Note: While the LED or display screen is red and the buzzer is sounding the
water from the system should NOT be consumed. If any water does pass through the
system during this period, please follow the disinfecon procedure as outlined in this
manual before the water is consumed. For Anon UV monitored systems, even though
they have a visual and audible warning built into the controller, a green LED or status
screen does not necessarily indicate that the water coming from this system is in fact
potable (safe to drink). These systems do not measure the level of disinfecon; they
simply measure the “on-o” status of the lamp. Please have your water checked for
microbiological contaminants on a regular basis.

NP4 & NP4-C Controllers
NP4 Series NP4-C Series
Simplisc in operaon, these systems feature a tri-
color LED that indicates system status and a 4-digit
display to indicate lamp life remaining. Pressing the
buon will change the display to indicate total running
me. When the UV lamp is on and within its operang
age, the LED will be green. When the UV lamp is not on
or the lamp life has expired, the LED will be illuminated
red and an audible buzzer will be sounding. To remedy
this condion, the UV lamp must be replaced with a
new genuine Neo Pure UV lamp.
NP5/6 & NP5/6-C Controllers
NP5 / NP6
Series
NP5-C /
NP6-C
Series
A full color LCD screen provides the user with a
detailed descripon of the system’s performance in
addion to providing any applicable fault messages
and system diagnoscs. The controllers used in both
the monitored and non-monitored are idencal. The
dierence is that the NP6 series of products includes
a UV intensity monitor. All NP5 controllers include
an “innite expandability port” located on the right
side of the controller. Simply plug in an oponal UV
sensor module into the expandability port of a non-
monitored controller and the system will now monitor
the UV intensity of the system!
NP5/6 & NP5/6-C Power-up Sequence
On start up, the controller will run through a diagnosc start-up and the sequence will
be displayed as follows on the color LCD:

16|Page
Next, the controller checks for and inializes any oponal modules that may be
aached to the system.

A nal module screen is displayed showing which specic modules were inialized.
The controller then displays the lamp opmizaon screen for 60 seconds to allow
the lamp to reach its opmum output. Finally, a nal “start-up complete” screen is
displayed. The system will now be ready to disinfect water ow.

NP5/6 & NP5/6-C Operaonal Screens
On systems without the UV monitor, the default screen shows the Neo Pure Home
Screen. At any point during operaon the user is able to scroll through the Neo Pure
Home Screen, Lamp life remaining, QR Code, Contact Info and Maintenance Parts
screens by pressing the buon located on the front of the controller.

17|Page
NP6 & NP6-C Operaonal Screens
On systems with the UV monitor, the system will display the same screens as on the
base system except the UV Intensity replaces the home screen. The UV Intensity screen
displays the level of UV light detected by the sensor. UV intensity can be aected by
poor water quality, scaling on the quartz sleeve and/or sensor, lamp failure or lamp
expiring. The following screens show the UV Intensity dropping.
Below 56%, the numbers and warning sign turn red and an audible chirp is given
by the ballast every 15 seconds. Below 51%, the screen is solid red and a constant
audible alarm is given. This alternates with a screen indicang “water may be unsafe
for consumpon”. With the solenoid module, the controller de-acvates the solenoid
valve, shung o all water ow.

At any point during this sequence, the audible chirp or alarm can be deferred for seven
days by holding the controller buon down for a period of ve seconds. The number
of deferrals used will be displayed as below. Once the deferral expires, the alarm will
sound once again. The deferral can be repeated up to three mes. PLEASE NOTE: At any
point aer lamp expiraon, the water may be unsafe for consumpon and should not
be consumed without another form of disinfecon.
System Service Suggested
NP5 & NP6 controllers will display the System Service Suggested
Screen every 6 months to remind consumers to maintain both their
UV and other preltraon. This will serve as a prompt only and will
not put the system into alarm. To clear this condion simply press
the buon located below the screen.

Lamp Replacement (NP4 / NP4-C systems)
Aer the lamp is expired, it must be replaced with the same part number as indicated by
the label on the reactor. Replace the lamp by unplugging the power for the controller,
then refer to Installaon, starng with step 11 (page 11) for instrucons on installing
the new lamp. To reset the mer in the controller, rmly hold down the buon on the
controller for 10 seconds. The controller will read “rSt3”, “rSt2”, “rSt1” and then beep.
The buon can now be released, the lamp countdown mer has been reset.
Lamp Replacement (NP5/6 & NP5/6-C systems)
Aer the lamp is expired, it must be replaced with the same part number as indicated
on the Maintenance Parts screen or on the label on the reactor. With the system
powered down, remove and discard the lamp key from the controller. The replacement
lamp is packaged with a lamp key on the connector at the end of the lamp. Remove
