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 can be 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 specialised tools required to cut into your exisng plumb-
ing
• 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 Atlas 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 should 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 Atlas 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 20 microns prior to an Atlas UV disinfec-
on system.

6|Page
Assembly
Unpack the system and ensure all the components are included with the system. Your system is
shipped with the following components:
“L” Series (Standard output lamp systems)

7|Page
“H” Series (High output lamp systems)

8|Page
System Sizing
All Atlas 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 paramaters will decrease the dose and therefore compromise the
microorganism inacvaon.
If you need to determine your maximum ow rate, you can simply ll a 1 gallon bucket with
water and me how long it takes to ll up. It is always beer to oversize your system than to
undersize. For example, if your pump delivers 8 gpm it is recommended to install any of the Atlas
10 gpm systems.
Locaon
For Point of Entry (POE) systems, choose a locaon where the main cold water line is accessable.
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 tap. Atlas recommends that a 20 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 of the UV
chamber 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 Atlas 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
pipework 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 reac-
tor to wood or drywall. If mounng to an alternate material
you will need to purchase the proper corresponding fasten-
ers.
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 Atlas system is not exceeded.
The ow restrictor should be installed on the outlet 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.
Figure 3. By-pass assembly
Note: Installaon of your Atlas disinfecon systems should com-
ply with applicable local regulaons.

Step 6: Once the system has been plumbed in, gently remove the quartz sleeve from its pack-
aging being careful not to touch the length with your hands. The use of coon gloves is recom-
mended 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.
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 (only with UV monitor upgrade). 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

11|Page
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 7
and 8. 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 recognised 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. Insert the UV lamp into the
reactor, being careful not to drop it.
Step 12: Plug the lamp connector into the lamp. Note the keying for proper alignment (see Fig-
ure 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 8.

Step 13: Tighten the capve ground screw to the ground lug on the UV reactor to ensure proper
grounding.
Figure 9. Ground Screw Connecon
Step 14: 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 pipework in the home or facility could be contaminated.
Use the following steps to fully disinfect the pipework throughout the enre home or facility.
Step 1: Check for and remove any “dead ends” in the pipework 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 lter housing and ll it with 1-2 cups of house-
hold bleach (most are 5.25% chlorine). Replace the lter housing 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 taps,
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 lter housing and ush the chlorine soluon by
opening all taps unl chlorine can no longer be detected. Your home has now been completely
disinfected with your Atlas 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 clean-
ing 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.

13|Page
Step 3: Release water pressure by opening a downstream tap 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 connec-
tor 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 a 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 cleaning on an annual basis. The following steps outline a basic clean-
ing 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 tap 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 reac-
tor 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
The Atlas system comes with a feature laden controller that incorporates both the lamp driver
(ballast) and control features in one water-ght case. Two controllers are available for the Atlas
systems (depending on your model).
Controller
These controllers feature a power factor corrected, con-
stant current lamp driver with a universal power input. 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 diag-
noscs. The controllers used in both the monitored and
non-monitored systems are idencal. All controllers in-
clude an “innite expandability port” located on the right
side of the controller. Oponal modules like the UV sen-
sor can be plugged into the expandability port of an Atlas
controller to give addional features.
Power-up Sequence
On start up, the controller will run through a diagnosc start-up and the sequence will be dis-
played as follows on the colour LCD:
Next, the controller checks for and inialises any oponal modules that may be aached to the
system.
UV Sensor
Module Check
Solenoid
Module Check

15|Page
4-20 mA

A nal module screen is displayed showing which specic modules were inialised.
The controller then displays the lamp opmisaon screen for 60 seconds to allow the lamp to
reach its opmum output, followed a nal “start-up complete” screen. The system will now be
ready to disinfect water ow.
Operaonal Screens
On systems without the UV monitor, the default screen shows the Atlas Home Screen. At any
point during operaon the user is able to scroll through the Atlas Home Screen, Lamp life re-
maining and QR Code/Contact Info screens by pressing the push buon located on the front of
the controller.

16|Page
Operaonal Screens with UV Monitor Upgrade
On systems that have the UV sensor installed, the default screen shows the UV Intensity. At any
point during operaon the user is able to scroll through the UV Intensity, Lamp life remaining
and QR Code screens by pressing the buon located on the front of the controller.
UV Intensity (with UV Monitor Upgrade)
The UV Intensity screens display 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.

17|Page
Lamp Countdown Sequence
The system counts down the number of days unl a lamp change is required.
At seven days remaining, the screen changes to a yellow cauon screen with an audible chirp ev-
ery 15 seconds. Past the zero day threshold, the screen changes to solid red and cycles between
a red “lamp expired” screen and a “water may be unsafe for consumpon” screen. The same
intermient audible chirp is heard throughout this lamp expired sequence.
At any point during this sequence, the audible chirp can be deferred by holding the controller
buon down for a period of ve seconds, aer which the screen below will be displayed. Aer
the seven days deferral expires, the alarm will sound once again. The deferral can be repeated
as many mes as you wish. 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.
Lamp Countdown Reset Sequence
When changing the lamp, the day countdown mer must be reset to match the newly installed
lamp. To reset, rmly hold down the buon on the controller while plugging the power cord back
into the outlet. Connue holding down the buon for ve seconds as indicated unl you hear an
audible chirp conrming the mer has been reset. The following two screens will be displayed
during this process.

Failure Modes
Hard Alarms: The following give a constant audible alarm. If present, the solenoid valve is closed,
and the 4-20, Volt free and ethernet module transmit the alarm.

Boil Water Advisory: If any failure occurs on an Atlas 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.
QR Codes
A QR code (Quick Response code) is a matrix barcode rst designed
for the automove industry. Atlas uses the QR code to store a link to
a specic page on our website. Users with a camera phone equipped
with the correct reader applicaon can scan the image of the QR
code and over a wireless network connect to a Atlas web page in the
phone’s browser. Atlas’ QR webpage has informaon on how to pur-
chase replacement components as well as a helpful video directory on
system servicing (i.e. How to change a UV lamp or quartz sleeve). To
access the QR code on the Atlas controller, press the control buon
twice and the QR code screen will appear as follows:

19|Page
Expansion Modules
Atlas 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 Atlas UV controllers. Contact
your authorised distributor for purchasing informaon.
VOLT FREE 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 1A-
120-230V AC/DC (use 16-22 AWG).
SOLENOID CONNECTION MODULE: Connects a
NORMALLY CLOSED line voltage solenoid valve to
the system. On a non-monitored system, the sole-
noid 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 re-
quired, the controller can be placed into a manual
override mode allowing for the ow of water in an
alarm condion.
4-20 mA MODULE: Outputs a 4-20mA signal of the
UV output to a remote device such as a data logger
or computer.
ETHERNET MODULE: Allows for all controller func-
ons to be connected to a computer via an Ether-
net cable.
