SECTION 1: Safety Instructions
WA R N I N G
During extended periods of no water ow, the water in your chamber
may become very hot (Approx. 140 °F, 60 °C) and can potentially lead to
scalding. It is recommended to run your water until very hot water has
been purged from the systems chamber. DO NOT allow water to contact
your skin during this time. To eliminate this condition, a temperature
management valve can be installed at the outlet of your UV system.
DO NOT pass water through the UV system for a minimum of 10
minutes after connecting and applying power (including after power
interruptions). This will avoid passing under-treated water that may,
in rare instances, pose health hazards.
The system contains a Germicidal UV Lamp. DO NOT operate the UV
Lamp when it is removed from the chamber. Unintended use or damage
of the system may result in the exposure of dangerous UV radiation. UV
radiation may, even in small doses, cause harm to the eyes and skin.
Changes or modications made to this system without the consent of
the manufacturer may render the system unsafe for operation and will
void the manufacturer's warranty.
CAUTION
Failure to follow these instructions could result in minor or moderate injury.
Carefully examine the disinfection system after installation. It
SHOULD NOT be plugged in if there is water on parts not intended
to be wet such as, the ballast controller or lamp connector.
Due to thermal expansion concerns and potential material degradation
due to UV exposure, it is recommended to use metal ttings and at least
10" of copper pipe on the outlet of your UV chamber.
Hg EXPOSURE: The UV lamp contains mercury. If the lamp breaks, avoid
inhalation or ingestion of the debris and avoid exposure to eyes and
skin. NEVER use a vacuum cleaner to clean up a broken lamp as this may
scatter the spilled mercury. Obey local regulations and guidelines for
the removal and disposal of mercury waste.
NOTICE
The UV lamp inside the disinfection system is rated at an eective
life of approximately 365 days or 9000 hours. To ensure continuous
protection, replace the UV lamp annually.
The UV system is NOT to be used or played with by children. Persons
with reduced physical, sensory or mental capabilities, or people who
lack of experience and knowledge, are also NOT to handle the UV
system unless they have been given supervision or instruction.
This system is intended to be permanently connected to the water lines.
This system is NOT intended to be used in or above water or outdoors or
used in swimming pools when persons are in the pool.
EXTENSION CORDS: If an extension cord is necessary, use only 3-wire
extension cords that have 3-prong grounding type plug and 3-pole cord
connectors that accept the plug from this system. Use only extension
cords that are intended for outdoor use. Use only cords having an
electrical rating not less than the rating of the system. A cord rated for
less amperes or watts than this system rating may overheat. Exercise
caution when arranging the cord so that it will not be tripped over or
pulled. DO NOT use damaged extension cords. Examine extension cord
before using and replace if damaged. DO NOT abuse extension cord.
Keep extension cord away from heat and sharp edges. A extension
cord from the receptacle before disconnecting this system from
the extension cord. Never yank cord to pull plug from outlet. Always
ground the plug into an appropriate outlet that is properly installed
and grounded in accordance with all local codes and ordinances.
1.3 WATER CHEMISTRY WATER QUALITY
Water quality plays an extremely important role in
the transmission of germicidal ultraviolet rays. It is
recommended that the water does not exceed the
following maximum concentration levels.
MAXIMUM CONCENTRATION LEVEL
Iron < 0.3 ppm (0.3 mg/L)
Hardness* < 7 gpg (120 mg/L)
Turbidity < 1 NTU
Manganese < 0.05 ppm (0.05 mg/L)
Tannins < 0.1 ppm (0.1 mg/L)
Uv transmittance
> 75% (call factory for
recommendations on
applications where UVT < 75%)
Eectively treating water with higher concentration
levels than listed above can be accomplished,
but may require added measures to improve water
quality to treatable levels.
UV DOSE
The units generate a UV dosage of at least 30,000
microwatt-seconds per square centimeter (µW-s/cm2),
even at the end-of-lamp life (EOL), which is more than
sucient to destroy most waterborne microorganisms,
such as bacteria, yeasts, algae, etc.
* Where total hardness is less than 7 gpg, the UV unit should operate eciently provided
the quartz sleeve is cleaned periodically. If total hardness exceeds 7 gpg, the water should
be softened. If your water chemistry contains levels in excess of those mentioned above,
proper pre-treatment is recommended to correct these water problems prior to the
installation of your UV disinfection system. These water quality parameters can be tested
by your local dealer, or by most private analytical laboratories. Proper pre-treatment is
essential for the UV disinfection system to operate as intended.

SECTION 3: Installation Instructions
3.1 UV HIGH OUTPUT SYSTEM INSTALLATION
The disinfection system is designed to be mounted
either horizontally or vertically at the point-of-entry
or point-of-use.
When installing the system in a horizontal position,
the outlet port must be pointing upwards to ensure
air is completely purged from the systems chamber.
(Refer to Figure 2).
NOTE: The ideal installation type is vertical with the
lamp connector and outlet on top. This helps prevent
water damage on the lamp pins, lamp connector and
prevents water from reaching an electrical zone.
- The ballast controller should be mounted above or
beside the chamber. Always mount the ballast controller
horizontally to help prevent moisture from running
down cord and causing a potential re hazard. Drip
loops on all cords connected to ballast controller are
highly recommended. (Refer to Figure 6).
- The complete water system, including any pressure
or hot water tanks, MUST be sterilized before start-up.
This can be done by ushing with chlorine (household
bleach) to destroy any residual contamination. (Refer to
Section 3.2).
- The UV system is intended for indoor use only,
DO NOT install disinfection system where it may be
exposed to the weather.
- Install the disinfection system on cold water line ONLY,
before any branched lines.
- A 5 micron sediment lter must be installed before the
disinfection system. The UV system should be the last
treatment the water receives before it reaches the faucet.

PROCEDURE:
1. Figure 3 (Next Page): Shows the installation of a
typical ultraviolet disinfection system and related
components that may be used for the installation.
The use of a by-pass assembly is recommended in
case the system requires “o-line" maintenance.
Please note, the system will require a supplementary
disinfection for the distribution system if any water is
used during by- pass condition.
NOTE: During by-pass, the water will NOT be disinfected
and a “DO NOT CONSUME THE WATER" tag should
be physically installed on the by-pass assembly until
the system has been sanitized and returned to service.
For more information, refer to Section 3.2. If the
water is necessary to be consumed while the system is
off-line, water must be boiled for 20 minutes prior
to consumption.
CAUTION
The electronic ballast controller MUST be connected to a Ground Fault
Protected Circuit (GFCI) receptacle.

2. Select a suitable location for the disinfection
system and its related components. Since it is
recommended to install a GFCI, make sure that
suitable location is taken into consideration prior to
installation.
The UV system can be installed vertically (inlet port at
the bottom) as shown in Figure 4 A, or horizontally as
shown in Figure 4 B.
Vertical installation is the most preferred method.
When selecting a mounting location, leave enough
space to allow the removal of the UV lamp and/or
quartz sleeve (typically a space equal to the size of
the chamber is appropriate).

SECTION 3: Installation Instructions
3. Mount the system to the wall using the supplied
clamps. Various connection methods can be used to
connect the water source to the UV system, but Union
Type connectors are recommended. The installation
of a ow restrictor device will help to maintain the
manufacturers rated ow. The ow restrictor should
be installed on the outlet port and is designed to be
installed in one direction only. Please ensure that
the ow of the water matches the ow direction as
indicated on the ow restrictor. Refer to Figure 5.
FLOW RESTRICTOR INSTALLATION
(Figure 5)
4. GROUNDING
To properly ground the system, attach the green
wire coming from the power source (ballast) to the
grounding lug on the UV chamber. Remove the
nut and slide the eyelet connector onto the screw.
Fasten the nut to the screw with a wrench.
(Figure 6)
NOTE: Flow Restrictor installation is optional but
mandatory when required to meet NSF certification.
NOTE: DO NOT solder connections while attached
to the system, this could damage the O-ring seals.
5. Mount the ballast controller horizontally to the
wall above the chamber and away from any water
connection point, to prevent any water from
potentially leaking onto the ballast controller by
means of a leak at a connection point or because
of a “sweating" system. Make sure you allow for a
“drip-loop" as shown in Figure 7 on the lamp, sensor,
and power cord, this will aid to prevent any water
from potentially entering the ballast controller.
DRIP LOOP
(Figure 7)
6. Install the POLARIS High Output UV lamp. Refer to
Section 4.1.
7. When all plumbing connections have been
completed, slowly turn on the water supply and
check for leaks. The most likely cause of leaks is from
the O-ring seal. In case of a leak, shut water o, drain
cell, remove the retaining nut, wipe the O-ring and
threads, clean and re-install.
8. Once it is determined that there are no leaks,
plug the system into the ground fault interrupter (GFCI
outlet) and check ballast controller to ensure the
system is operating properly. The ballast controller
will illuminate without any alarms.
CAUTION: DO NOT look directly at a powered up,
glowing UV lamp.
9. Allow the water to run for a few minutes to
clear any air or dust that may be in the chamber.
NOTE: When there is no ow, the water in the chamber
will become warm, this is because the UV lamp is always
on. To remedy this, run a cold water tap anywhere in
the house for a minute to ush out the warm water.

3.2 UV DISINFECTION
Ultraviolet (UV) disinfection is a physical disinfection
process which does not add any potentially harmful
chemicals to the water. As UV does not provide
a disinfection residual, it is imperative that the
entire distribution system located after the UV be
chemically disinfected to ensure that the plumbing
system is free from any bacteriological contaminants.
The disinfection process must be performed
immediately after the UV unit is installed and repeated
thereafter whenever the UV is shut down for service,
without power, or inoperative for any reason.
The procedure for sanitizing the plumbing system
is readily accomplished as follows:
UV DISINFECTION PROCESS
NOTES:
- The addition of chlorine (bleach) to a hot water
tank that has in the past been fed with untreated
raw water with high levels of other contaminants
(iron, manganese, hydrogen sulphide, organics, etc.)
will result in oxidation of these contaminants and
may require repeated flushing of the hot water tank.
This contingency must be dealt with independently
underthestart-up procedurefor anyotherconditioners
that may form a part of the pre-treatment for the UV unit.
- The above disinfection procedure will result in a massive
chlorine residual far in excess of the 0.5 to 1.0 mg/L
typically present in municipally chlorinated water and
of a magnitude consistent with the minimum 50 mg/L
chlorine solution recommended for the disinfection
of distribution systems known to be contaminated.
DO NOT consume water until complete system has
been flushed.

WARNING!
The advanced warning system has been installed to provide the optimum protection against microbiological
contamination in water. DO NOT disregard the warning signals. The best way to ensure optimum UV performance
is to have the water microbiologically tested by a recognized testing agency on a regular basis.
5.1 LAMP LIFE REMAINING DAYS
- The default screen will display the total lamp life
remaining (in days). The ballast controller will count
down the number of days remaining until the lamp
requireschangingfrom365daysto1day( to ).
- At “0" days, the ballast will display and sound an
intermittent audible buzzer (1 second on, 5 seconds
o), indicating the need to change the lamp.
5.2 LAMP ALARM SILENCING 7 DAYS
- Once the or end of lamp life message is shown on
the LED display, the audible alarm can be deferred up to

TROUBLESHOOTING
SYMPTOMS POSSIBLE CAUSES SOLUTIONS
PRESSURE DROP
Sediment pre-lter is clogged
Replace lter cartridge with a new 5 micron cartridge.
Note: Check source water supply as uctuations may occur
in source pressure.
Flow regulator (if installed)Flow regulator will result in pressure drop when approaching full ow.
HIGH BACTERIA COUNT
Quartz sleeve is stained or dirty Clean sleeve with scale cleaner and eliminate source of staining problem
(soften hard water if necessary), refer to Section 4.2.
Change in feed water quality Have source water tested to ensure that water quality
is still within allowable limits for this system.
Contamination in water lines after UV system
It is essential and imperative that the euent water stream
be shocked with chlorine (bleach) before water leaves
UV system disinfection system must have a bacterial free
distribution system to work eectively. Refer to Section 3.2
Possible break-through of sediment through pre-lter
Have source water tested for turbidity - may need Step ltration
(20 micron lter followed by a 5 micron lter followed by UV system)
in order to catch all sediment entering water system.
HEATED PRODUCT WATER Common problem caused by infrequent use of water Run water until it returns to ambient temperature.
WATER APPEARS MILKY Caused by air in the water lines Run water until air is purged.
UNIT LEAKING WATER
Problem with O-ring seal
(on retaining nut and/or UV sensor)
Ensure O-ring is in place, check for cuts and/or abrasions, clean O-ring,
moisten with water, lubricant and re-install, replace if necessary.
Condensation on chamber caused
by excessive humidity and cold water Check location of disinfection system and control humidity.
Inadequate inlet/outlet port connections Check thread connections, reseal with Teon® tape and re-tighten.
SYSTEM SHUTTING
DOWN INTERMITTENTLY Interrupted ballast controller
Ensure system has been installed on its own circuit,
as other equipment may be drawing power away from UV .
(i.e. pump or fridge).
UV system should not be installed on a circuit
which is incorporated into a light switch.

THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY
LIMITED REMEDY AND NOTWITHSTANDING THE PROVISIONS OF ANY OTHER AGREEMENT BETWEEN THE

16. Indemnity for Infringement of Intellectual Property Rights.
(a) The Buyer shall defend and indemnify the Seller against all acons, claims, demands, penales and costs
by third pares in tort, or for infringement, or alleged infringement, of patents, trademarks, copyrights,
trade dress, trade secret or other rights of any third party resulng from the goods manufactured in
accordance with the Buyer’s specicaons or based on any informaon provided by the Buyer. The Buyer
will defend any acon against the Seller for tle, patent, trademark, copyright infringement, or other
claimed by a third party at the Buyer’s sole cost and expense. (b) The Seller shall have no liability for
infringement of any patents, trademarks, copyrights, trade dress, trade secrets or similar rights except
as provided in this provision. The Seller will defend and indemnify the Buyer against allegaons of
infringement of patents, trademarks, copyrights, trade dress and trade secrets ("Intellectual Property
Rights"). The Seller will defend at its expense and will pay the cost of any selement or damages awarded
in an acon brought against the Buyer based on an allegaon that an item sold pursuant to this contract
infringes the Intellectual Property Rights of a third party. The Seller’s obligaon to defend and indemnify
the Buyer is conngent on the Buyer nofying the Seller within 10 days aer sole control over the defense
of any allegaons or acons, including all negoaons for selement or compromise. If an item sold
hereunder is subject to a claim that it infringes the Intellectual Property Rights of a third party, the Seller
may, at its sole expense and opon, procure for the Buyer the right to connue using said item, replace
or modify said item so as to make it non-infringing, or oer to accept return of said item and return the
purchase price less a reasonable allowance for depreciaon. Notwithstanding the foregoing, the Seller
shall have no liability for claims of infringement based on informaon provided by Buyer, or directed to
items delivered hereunder for which the designs are specied in combinaon or use in a system of any
item sold hereunder. The foregoing in this provision shall constute the Seller’s sole and exclusive liability
and the Buyer’s sole and exclusive remedy for infringement of Intellectual Property Rights.
17. Lien.
In addion to any right of lien to which the Seller may by law be entled, the Seller shall have a general
lien on all goods of the Buyer in the Seller’s possession (although such goods or some of them may have
been paid for) the unpaid price of any other goods sold and delivered to the Buyer by the Seller under the
same or other contracts.
18. Waiver.
The Seller’s rights shall not be aected or restricted by any indulgence or forbearance granted to the
Buyer. No waiver by the Seller of any breach shall operate as a waiver of any later breach.
19. Force Majeure.
The Seller shall be excused from performing any of its obligaons under this Agreement which are
prevented or delayed by any occurrence not within the reasonable control of the Seller, including but
not limited to, accidents, acts of God, destrucon or damage to the goods or the Seller’s manufacturing
plant, delays or failures in delivery of carriers or suppliers, shortages of materials, strikes or other labor
maers, oods, earthquakes, re, riots, explosions, or any regulaons, rules, ordinances or orders of any
governmental authority, federal, state or local, whether such cause exists at the date of the order or not.
20. Buyer’s Representaon of Solvency.
The Buyer hereby represents that as of the signing of this Agreement it was not insolvent within the
meaning of the Uniform Commercial Code or any Bankruptcy Laws.
21. Assignment and Delegaon.
The rights and obligaons of the pares under this Agreement may not be assigned or delegated, except
on the express wrien consent of the other party to the assignment or delegaon.
22. Integraon.
The rights and obligaons of the pares and the terms and condions set forth herein, together with
any amendments, modicaons and any dierent terms and condions expressly accepted by the Seller
in wring, shall constute a complete and exclusive statement of the terms of this Agreement. This
Agreement supersedes not only all prior agreements, but also oral agreements made contemporaneously
with the execuon of this Agreement. All such materials may not be used to supplement, explain, or
contradict the terms of this Agreement.
23. Severability.
If any of these condions or any part thereof purports to exclude or restrict or limit any liability and such
exclusion or restricon or limitaon is prohibited or rendered void or unenforceable by any legislaon to
which it is subject, or is itself prohibited or rendered void or unenforceable by any legislaon to which it
is subject, then the exclusion, restricon or limitaon on the condion or part thereof in queson shall
be so prohibited or rendered void or unenforceable and the validity or enforceability of any other part of
these provisions shall not thereby be aected.
24. Governing Law/Limitaon on Acons.
The terms, condions, rights, and obligaons under this Agreement shall be construed under the laws of
the State of California, without regard to principles of conicts of laws. No acons arising out of the sale
of the items sold hereunder or this Agreement may be brought by the Buyer more than two (2) years aer
such cause of acon accrues.
