PRODUCT APPLICATION
ConstruCtion
• The water purier is designed to mount horizontally.
• The water purier’s chamber is passivated and electropolished type 304 Stainless Steel.
• EASY-OFF TM End Caps enable quick and easy lamp change, without disconnecting from the water supply or draining the
purier. No tools are required. Always disconnect electrical power when changing lamp.
PrinCiPle of oPeration
The MINIPURE® design has been carefully conceived to provide adequate germicidal dosage throughout the disinfection
chamber. The dosage, as it applies to ultraviolet disinfection, is a function of time and the intensity of ultraviolet radiation to
which the water is exposed. The exposure time, in seconds, is the total time it takes the water to ow through the disinfection
chamber exposing it to the germicidal lamp. Exposure time is related to the ow rate; the higher the ow rate, the lower the
exposure time or the lower the ow rate, the higher the exposure time. The ultraviolet intensity is the amount of energy, per unit
time, emitted by the germicidal lamp. The dosage is the product of ultraviolet intensity and the exposure time. The operation of
the MINIPURE® is as follows:
• Water enters the purier and ows into the annular space between the quartz sleeve and the chamber wall.
• Suspended microorganisms are exposed to the ultraviolet rays emitted by the germicidal lamp.
• The LED indicator light, located on the ballast, provides visual indication of germicidal lamp operation.
• Water leaving the purier is instantly ready for use, no further contact time is required.
limitation of use
The water purier is intended for the use with visually clear water, not colored, cloudy or turbid. See “Water Quality” section
below. The water purier is NOT intended for the treatment of water that has an obvious contamination or intentional source,
such as raw sewage, nor is the unit intended to convert wastewater to microbiologically safe drinking water.
Water Quality
Water quality plays a major role in the transmission of germicidal ultraviolet rays. It is recommended that the water does not
exceed the following maximum concentration levels:
Table 1 - Maximum Concentration Levels
Turbidity < 1 NTU
Manganese 0.05 mg/1
Total Suspended Solids 10 mg /1
pH: 6.5 - 9.5
Color: None
Hardness 6 GPG or 102.6 PPM
Iron 0.3 mg/1
Tannins: < 0.1 ppm (0.1 mg/l)
UV Transmission >85% per cm*
* Contact Factory for recommendations on applications where UV transmission is < 85%
Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added
measures to improve water quality to treatable levels. If, for any reason, it is believed the ultraviolet transmission is not
satisfactory, contact the factory.

INSTALLATION
loCation
1. The water purier is intended for indoor use only. The water purier is designed to mount horizontally. The water purier
should be protected from the elements and from temperatures below freezing. The ambient temperature, in the area
surrounding the water purier, should be between 35o F and 100o F.
2. Electrical power supplied to the water purier MUST match power requirements listed on the water purier. Use of a voltage
surge protector is recommended.
3. Install water purier within 48” of a known good ground. Water Purier will need to be installed into
approved ground fault circuit interrupt (GFCI) receptacle. Where a 2-prong or unprotected 3-prong receptacle is encountered,
it must be replaced by a properly grounded Ground Fault Circuit Interrupt (GFCI) receptacle. Installation must be in
accordance with the National Electrical Code and any local codes and ordinances by a qualied electrician.
4. The water purier should be located in a dry, well-lit area, which provides enough room to perform routine maintenance.
This includes a minimum distance of one chamber length from the chamber end, to allow for cleaning and/or the
changing of the lamp and quartz sleeve as well as a minimum of 6” on the opposite end of the water purier. Minimum
clearance to oor 18’’.
5. The water purier should always be located closest to the point of use. This reduces the chance of the puried water being
re-contaminated by bacteria in the water distribution system after the water purier.
6. As with any water handling device, the water purier should be located in an area where any possible
condensation or leakage from the water purier, any purier accessory and/or plumbing will not result in damage to the area
surrounding the water purier. For added protection, it is recommended that a suitable drain pan be installed under
the purier. The drain pan must be plumbed to an adequate, free owing drain to prevent water damage in event of
a leak. There are numerous leak detection/ood stop devices, available on the market today, designed to stop ow
of water, reducing the chance of water damage due to leakage. For more details regarding leak prevention and/or
limiting damages due to leaks please contact factory.
7. The water purier should be located after all other water devices, such as De-ionizers, Water Softeners, Carbon Filters,
Pre-Filters, Reverse Osmosis, Pressure Tanks, and Pumps. This eliminates the possibility of the puried water being
re-contaminated by bacteria in any of these units.

IN ORDER TO PERFORM THIS TASK, BE SURE TO WEAR THE FOLLOWING SAFETY
EQUIPMENT: SAFETY GOGGLES OR A FACE SHIELD, AS WELL AS GLOVES.
1. Remove water purier from shipping carton. Inspect water purier, power cord and plug for damage. Do not operate if there
is any damage to the purier, power cord or plug. All models, of the MINIPURE®line of water puriers, are shipped with the
lamps packed separately. Keep the lamp aside for installation once the purier has been properly installed.
2. Units occasionally experience damage in shipment due to the fragility of the quartz sleeve. It is therefore recommended to
inspect the water purier for damage to the quartz sleeve after it has been removed from the shipping carton. Each end of the
unit as well as the inlet and outlet should be viewed to see if the quartz sleeve has experienced damage. If the quartz sleeve
shows signs of damage it should be replaced before the purier is pressurized. See “Quartz Sleeve Installation, Cleaning
or Replacement” in the “Maintenance” section for the proper method of replacing the quartz sleeve in your water purier.
3. The water purier should be mounted horizontally on a at dry surface. The purier should not be solely supported by its
plumbing connections. Securing the water purier using the optional wall bracket kit is recommended.
4. The water purier must be connected to the cold water line only. Inlet water temperature should not exceed 100o F.
5. Installation requires a 5-micron sediment lter be installed, in line, prior to the water purier. The sediment lter will stop
or trap large particulates from entering the water purier. Particulates may cause deposits on the quartz sleeve, as well as
interfere with the purier’s ability to disinfect the water. The sediment lter may also help to reduce the amount of routine
cleanings of the quartz sleeve.
6. Shut off valves should be installed on both the inlet and outlet sides of the water purier. The use of bypass valves is not
recommended. The shut off valves allow the purier to be isolated from the water supply, which is required when removing
the quartz sleeve.
7. Unions should be installed on both the inlet and outlet of the water purier; this will allow easy removal of the water purier
from the plumbing, if required. Apply Teon®tape to threads of inlet and outlet ports to ensure a tight seal.
Figure 3 - 120v and 220v 50/60Hz (ballast no. 10-0508B and 10-0504B)
8. When all plumbing connections are complete, allow water to enter the water purier at a low ow rate, until the purier is
full. NOTE: Close the purier outlet valve to pressurize the chamber. With the purier pressurized, it should be checked
for leaks. Once it is determined that there are no leaks, the inlet valve can be fully opened.
9. Unpack the lamp and ballast. While holding lamp end, carefully push lamp socket on. Carefully slide lamp straight into the
quartz sleeve, without angling. Push the end cap on, over the static gland nut. Attach the ground connector to the grounding
stud of the chamber, with included hardware (see steps 1, 2, and 3 on Page 8)
To ensure proper operation and safety of your water purier, your unit must be grounded
to a known good ground.
Lamp and quartz sleeve are easily damaged. Exercise care when handling.

8
10. Plug ballast into an approved Ground Fault Circuit Interrupt (GFCI) receptacle. Where a 2-prong or
unprotected 3-prong receptacle is encountered, it must be replaced by a properly grounded Ground Fault Circuit Interrupt
(GFCI) receptacle. Installation must be in accordance with the National Electrical Code and any local codes and ordinances
by a qualied Electrician.
11. Once the plumbing hook ups are made, it is a good practice to disinfect the “downstream” plumbing between the purier
and point of use. This is done by introducing chlorine or other disinfectant solution directly into the purier chamber;
100-ppm of chlorine is suggested. With the disinfectant solution in the purier chamber, turn the ultraviolet purier on.
Open the “downstream” outlet until a chlorine or disinfectant solution odor is noticed. Close the outlet and allow the
disinfectant to remain in the plumbing for at least three (3) hours. Flush the plumbing with ultraviolet puried water; allow
the water to run for a minimum of 5 minutes before use (to ensure no chlorine or disinfectant solution smell can be detected),
this will allow the chlorine or disinfectant solution to be ushed through the pipes.
12. For added protection, a suitable drain pan must be installed under the purier. The drain pan must
be plumbed to an adequate, free owing drain to prevent water damage in the event of a leak. There are numerous leak
detection/ood stop devices, available on the market today, designed to stop the ow of water, reducing the chance of water
damage due to leakage. For more details regarding leak prevention and/or limiting damages due to leaks, please contact
the factory.
reCommended oPtions
1. SENTRYTM Safety Sensor: Indicators provide constant visual monitoring of normal operation. In the event of ballast or lamp
failure the safety sensor indicates an alarm condition. The safety sensor is capable of operating an optional PromateTM Audio
Alarm and /or PromateTM Solenoid Valve.
2. PromateTM Audio Alarm: Activated by the Ultraviolet Monitor or Safety Sensor, alerts the user to any malfunction detected.
3. PromateTM Time Delay Mechanism: Provides a 2-minute warm up period during which the ultraviolet lamp achieves its
full germicidal output before the water is allowed to ow through the water purier. The time delay mechanism is used in
conjunction with, and is electrically connected to the Solenoid Valve.
4. PromateTM Solenoid Valve: Operated in conjunction with the GUARDIANTM Ultraviolet Monitor, Safety Sensor or Time
Delay Mechanism, this valve prevents water ow through the water purier when an abnormal condition is detected or in the
event of power failure.
5. SureFLOTM Flow Control Valve: Limits water ow to the rated capacity of the purier. The ow control valve is located
in line prior to the water purier, and should be protected from ultraviolet exposure by the use of a 90-degree elbow tting
between the ow control valve and the water purier. Unless otherwise specied, PVC ow control valves are supplied.
Stainless Steel Flow Control Valves are available for certain models. All PVC and Stainless Steel ow control valves are male
NPT. Consult Factory for other ow control valves.
6. PromateTM Elapsed Time Indicator: A non-resettable display of the water purier operating hours. Useful for scheduling
and recording maintenance and lamp replacement.
7. PromateTM Safety Goggles: Safety eyewear MUST be used as general-purpose safety protection and for additional
shielding from ultraviolet rays.
8. PromateTM Stainless Steel Wall Mounting Kit: Provides professional nish. Pre-drilled and ready for quick and easy
mounting of water purier. Suitable for wall or surface mounting.
9. PromateTM Face Shield: Lightweight visor with adjustable headgear provides eye and face protection from ultraviolet rays.
NOTE: The recommended options above are available from Atlantic Ultraviolet Corporation®or a distributor of their
products. For the other devices that may be required for your application, please contact your local water treatment
dealer, plumber or plumbing supplier.

MAINTENANCE
The water purier is designed to operate with a minimal amount of maintenance, providing the water quality does not exceed
maximum concentration levels, see “Water Quality” in the “Product Application” section. Ordinary maintenance consists of:
• Lamp replacement is recommended every 10,000 hours of operation, approximately 12 months of continuous service.
• Cleaning of the quartz sleeve, when conditions warrant. It is recommended that the inspection of quartz sleeve be performed
after one month of use. If quartz sleeve is found to be coated (not clear), then frequency of cleaning must be done more often.
Deposits or discoloration on the surface of quartz sleeve are caused by excessive levels of the subject contaminant within
the water that is in contact with the quartz sleeve. Most deposits on the quartz sleeve are caused by an excess of calcium
(hardness), iron or manganese. Table 1 on Page 4 lists the maximum recommended concentration of these minerals in the
water that passes through the ultraviolet purier. If you encounter difculty due to deposits on the quartz sleeve, your dealer
will be able to recommend suitable pretreatment to reduce or eliminate the offending contaminant. If quartz sleeve is clean
(clear) then frequency of cleaning may be extended.
• Always disconnect the water supply and completely drain the water purier if it will be subjected to temperatures
below freezing.
• Contact factory with questions.
insPeCtion
1. Regularly inspect the water purier to ensure that the germicidal lamp is still in operation.
• An LED indicator light, located on the ballast, provides visual indication of germicidal lamp operation. This provides an
indication of lamp operation and does not indicate the level of ultraviolet intensity or transmission through the water.
• Ballasts have a built-in audio alarm which will indicate lamp failure.
• On puriers so equipped, the SENTRYTM Safety Sensor provides visual indication of ballast and ultraviolet lamp operation
2. To ensure proper operation of the water purier, regular biological testing of the purier outlet water should be performed on a
schedule recommended by local public health authorities, or at minimum; at installation, quarterly for the rst year of service
and annually, at lamp replacement, for the life of the water purier.
3. Additional testing should be performed whenever modications, change or additions are made to plumbing system, pumps,
well source water etc. to ensure adequate disinfection under new condition.
4. As with any water purier installation, routine maintenance is necessary to ensure your equipment is operating correctly.
Regular inspection must also include the inspection of the ground to ensure grounding wires are secure to both the water
purier and grounding point as originally installed. Regular inspection must also include conrmation that approved ground
fault circuit interrupt (GFCI) receptacle is still operational and that water purier is plugged into this GFCI. Any components
which are damaged, or broken should be replaced.
breakage
Broken Quartz is SHARP. It is recommended that Protective Goggles or Face Shield and Gloves are worn.
Wear protective gloves when handling broken ultraviolet lamps and/or quartz sleeves. In the event of breakage,
DO NOT use a household vacuum cleaner to pick up fragments of quartz. Sweep up debris into a plastic bag and
dispose of properly.

4. Unscrew static gland nuts from each end of the chamber. Avoid striking quartz sleeve with static gland nut.
5. Remove Teon® washer and O-Ring from both ends of quartz sleeve. Teon® washer will sometimes remain within the static
gland nut. If so, remove Teon® washer from static gland nut before proceeding.
6. Carefully remove quartz sleeve from chamber. NOTE: It is advisable to support the quartz sleeve on the opposite end
with your nger so that it does not drop to the bottom of the chamber as it slides into the chamber.
7. Once the quartz sleeve is removed, clean with alcohol or a mild, non-abrasive detergent. Stubborn stains usually can be
removed with a dilute hydrochloric acid.
NOTE: Follow all manufacturer’s instructions and precautions when handling chemicals.
8. Reassemble in reverse order. Make sure the quartz sleeve protrudes an equal distance past each threaded nipple. Be sure
O-Rings are placed on quartz sleeve before Teon® washer.
9. Tighten static gland nuts rmly by hand only, DO NOT USE HAND TOOLS. Tightening with hand tools is likely to cause
quartz sleeve to break.
10. Slowly restore water supply to water purier and check for leaks.
11. If no leaks occur, reinstall lamp, following the steps in “Lamp Installation or Replacement” section.
Germicidal ultraviolet rays are harmful to eyes and skin. Do not restore power to water purier until

1. Disconnect power to water purier.
• For 120v 50/60Hz version using ballast no. 10-0508B or 230v 50/60Hz version using ballast no. 10-0504B, remove
the ground connector from the chamber and go to the next step.
2. Shut off water supply to water purier via inlet and outlet shut off valves and drain chamber, if possible.
3. Follow the steps in “Quartz Sleeve Installation, Cleaning or Replacement” to remove lamp and quartz sleeve.
4. Unscrew static gland nuts from each end of the chamber. Avoid striking quartz sleeve with static gland nut.
5. Remove Teon® washer and O-Ring from both ends of quartz sleeve. Teon® washer will some times remain within the static
gland nut. If so, remove Teon® washer from static gland nut before proceeding.
6. Carefully remove as much of the broken quartz sleeve as possible, from each end of the chamber.
7. To remove fragments of quartz sleeve, hold the purier vertically and shake. The quartz fragments will break and drop out
of the purier through the gland tting. Flush water through chamber being careful to remove all quartz fragments from the
interior of the chamber.
8. Carefully discard all pieces of the broken quartz sleeve.
9. Align the end of the quartz sleeve with the gland tting of the chamber.
10. Carefully slide the quartz sleeve into the chamber, guiding it through the gland tting. NOTE: Use care to keep the quartz
sleeve parallel to the chamber, angling the quartz sleeve in any direction could result in the breakage of the quartz sleeve.
11. As the quartz sleeve nears the far end of the chamber, support the quartz sleeve by inserting your nger through the far end
gland tting and into the quartz sleeve. This will minimize the possibility of breaking the quartz sleeve as it passes through
the gland tting.
12. Center the quartz sleeve in the chamber, making sure the quartz sleeve protrudes an equal distance past each threaded gland
tting, of the chamber.
13. Re-install O-Rings, Teon® washers, and static gland nuts. Be sure O-Rings are placed on quartz sleeve before Teon®
washer. Tighten static gland nuts rmly by hand only, DO NOT USE HAND TOOLS. Tightening with hand tools is likely to
cause quartz sleeve to break.
14. When all connections are complete allow water to enter the water purier at a low ow rate until the purier is pressurized.
With the purier pressurized, it should be checked for leaks.
15. If no leaks occur, reinstall lamp, following the steps in “Lamp Installation or Replacement” section on Page 10.

ballast no. 10-0508b and 10-0504b Have lamP-out ProteCtion
If power is applied to the ballast without a lamp connected to the circuit or if the lamp fails, the ballast’s lamp-out protection
will prevent the ballast from operating, and a red LED light will illuminate and audio alarm will sound. To reset: disconnect the
ballast from power and reconnect or replace the lamp. The ballast must remain disconnected from power for (2) minutes to
reset. After 2 minutes restore input power, ballast should resume proper operation.
The equipment that this ballast is used with requires connection to a known good ground. It is the User’s
responsibility to ensure that their equipment is properly grounded in compliance with the National Electrical Code and any
applicable local codes. Equipment wiring and hook up should be performed by a qualied, licensed electrician. Failure to comply
with this requirement could result in serious injury or death.

12volt and 24volt Direct Current (DC) ballasts and units.
Many Individuals regard ballasts and units powered by 12volt and 24volt Direct Current (DC) to be relatively benign from a
safety standpoint. However, a DC ballast, in order to operate an ultraviolet discharge lamp, must produce an output as high as
600volts. This voltage is high enough to produce a very serious or even lethal electric shock. IT IS IMPERATIVE that all DC
ballasts and DC ultraviolet units be wired and grounded appropriately.
Failure to ground all Direct Current (DC) ballasts and/or the equipment it is employed in,
can result in serious injury or death.
