Congratulaons on purchasing this ultraviolet disinfecon system. By
purchasing an Atlas UV Disinfecon system you are receiving not only
a high quality product but also peace of mind. Protecng your water
supply with a UV system gives you reassurance that your family will
have access to safe drinking water throughout your enre home with no
chance of microbiological contaminaon. This is a chemical free process
which is simple in its concept and eecve in its ability to inacvate
microorganisms present in the water supply. Simple maintenance,
connuous disinfecon and ulmately safe water, Atlas makes it that easy.

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.

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)

“H” Series (High output lamp systems)

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.

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.
