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 this equipment, 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 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 SpringWell 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 SpringWell 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 UV disinfecon
system.

System Sizing
All 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 micro-
organism 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 near-
est 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.
The system must be installed 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. SpringWell 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 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 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 it
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.

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 (ordered separately). 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.
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 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 (UV5 & UV6
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
7).

Step 13: Plug the lamp connector into the lamp. Note the
keying for proper alignment (see Figure 8a, 8b). 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.
Step 14: Tighten the capve ground screw to the ground lug
on the UV reactor to ensure proper grounding(Figure 10).
Step 15: Your system is now ready to be plugged into the
appropriate GFCI protected outlet. Refer to the following
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 minimum 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 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 any). 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, 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 quartz 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.
Cleaning the UV Sensor
Depending on the water quality, the UV sensor may require periodic cleaning. At a minimum,
the UV sensor 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 any). 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 8 from the installaon secon of the manual.

Operaon
UV 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 (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 UV4 and UV5 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.
UV4 Controllers

Simplisc in operaon, these systems feature a tri-
colour LED that indicang 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 SpringWell UV lamp.
UV5 & UV6 Controllers
UV5/6
Series
UV5/6-C
Series
A full colour 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 UV5 and UV6 are idencal. The dierence is that
the UV6 series of products includes a UV intensity
monitor. All UV5 and UV6 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 UV5 controller
and the system will now monitor the UV intensity of
the system!
UV5 and UV6 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 colour LCD:

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

- UV Sensor
- Solenoid
- 4-20 mA
- WIFI

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.

UV5 Operaonal Screens
On systems without the UV monitor, the default screen shows the Home Screen. At any point
during operaon the user is able to scroll through the 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.
UV6 Operaonal Screens
On systems with the UV monitor, the system will display the same screens as on the UV5 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.

15|Page
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.

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
UV5 & UV6 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 (UV4 systems)
Aer the lamp is expired, it must be replaced with the same part number as indicated by the
label on the reactor. Begin replacing the lamp by unplugging the power for the controller, then
refer to Installaon (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 (UV5 & UV6 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 the key from the lamp and place
it in the controller. Refer to Installaon (page 11) for instrucons on installing the new lamp.

Warning: Aer any hard alarm, the home or facility should be disinfected. Follow the steps
under the “System Disinfecon” heading.
Temperature Management Devices
Your UV system is designed to run connuously to ensure opmal disinfecon. However, during
periods when no water is drawn through the system, the energy from the disinfecon process
can cause the temperature of the water inside the chamber to rise. In extreme situaons
elevated water temperature or the uctuaon in temperature can lower the output of the UV
lamp. In these cases, or if the elevated water temperature is a nuisance, SpringWell recommends
one of the following forms of temperature management devices.
Cooling Fan - Designed for use on High Output systems, the fan runs connuously to
cool the water by forced convecon. The long-life fan is powered independently
using a compact modular power adapter that operates from 90-265V (47-63Hz).
Order PN SPRW-130014.
Temperature Relief Valve (TRV) - On reaching a higher temperature, the TRV is
designed to drain a small amount of water to allow fresh, cooler water to enter the
system. The TRV works without power and comes complete with 10’ of drain line.
Order PN SPRW-UV-TRV05 for 1/2” ports, PN SPRW-UV-TRV07 for 3/4” ports, PN
SPRW-UV-TRV10 for 1” ports and PN SPRW-UV-TRV15 for 1 1/2” ports.
Boil Water Advisory: If any failure occurs on a UV system, the water must not be used for
human consumpon unl the system is returned to a safe operaonal mode. If the water
is used for human consumpon during this period, the water must be boiled (minimum 20
minutes at a full boil) prior to consumpon.

Expansion Modules
Controllers incorporate an “Innite Expandability Port” (IEP)
which allows for expansion to the UV sensor and all other
modules. Each module (including the sensor) comes with
both a male and female connecon. Connect any device to
the controller and all subsequent devices are then connected
into the female end of last device added in a “daisy chain”
conguraon.
The following oponal expansion modules are available for use on UV5 & UV6 UV controllers.
Contact your authorized distributor for purchasing informaon.
REMOTE ALARM CONNECTION MODULE: Allows for a
connecon to a remote device such as a buzzer, light, alarm
system, PLC, etc., via a pair of contacts. In normal operaon
the OK and COM contacts will be connected, and in a fault
condion (Low UV, Lamp fail, Power Fail), the Fault and COM
contacts will be connected. Maximum contact rang is 30V / 1A
(use 16-22 AWG). Order PN SPRW-MOD-RAM.
SOLENOID CONNECTION MODULE: Connects a NORMALLY
CLOSED line voltage solenoid valve to the controller. Maximum
contact rang is 240VAC (50-60Hz) / 30VDC / 2A. On a non-
monitored system, the solenoid will only close on a lamp failure
error. On a monitored system, the solenoid is closed when
the UV level drops below 50%. Also note that in cases where
emergency use of untreated water is required, the controller
can be placed into a manual override mode allowing for the
ow of water in an alarm condion. Order PN SPRW-MOD-
SOL1.
4-20 mA MODULE: Outputs a 4-20mA signal of the UV output
to a remote device such as a data logger or computer. Order PN
SPRW-MOD-420.
The WiFi module and accompanying IoT applicaon allows you
to connect your UV system to a smart phone, tablet, computer
or other connected plaorm. View system status, receive SMS
or email messages of alarm condions and monitor the health
of your UV from anywhere via this connected plaorm. Connect
the device via the APP found on Google Play or the APP Store
and connect your UV device to your router, then download the
soware for your connected device. Order PN MOD-APP.
The Ultrasonic Flow Meter enables your UV system to dim
power in mes of low to no ow, saving you money on energy,
reducing water temperature, and decreasing the risk of fouling.
