PRODUCT APPLICATION
CONSTRUCTION
• The water purifier is designed to mount horizontally.
• The water purifier’s chamber is passivated and electropolished type 304 Stainless Steel.
• EASY-OFF TM end caps allow for quick and easy lamp change, without disconnecting from the water supply or draining the
purifier. No tools are required.
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 flow through the disinfection
chamber exposing it to the germicidal lamp. Exposure time is related to the flow rate; the higher the flow rate, the lower the
exposure time or the lower the flow 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 purifier and flows 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 purifier is instantly ready for use, no further contact time is required.
LIMITATION OF USE
The water purifier is intended for the use with visually clear water, not colored, cloudy or turbid. See “Water Quality” section
below. The water purifier 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 purifier is intended for indoor use only. The water purifier is designed to mount horizontally. The water purifier
should be protected from the elements and from temperatures below freezing. The ambient temperature, in the area
surrounding the water purifier, should be between 35oF and 100oF.
2. Electrical power supplied to the water purifier MUST match power requirements listed on the water purifier. Use of a voltage
surge protector is recommended.
3. CAUTION: Install water purifier within 48” of a known good ground. Water Purifier 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 qualified electrician.
4. The water purifier 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 purifier. Minimum
clearance to floor 18’’.
5. The water purifier should always be located closest to the point of use. This reduces the chance of the purified water being
re-contaminated by bacteria in the water distribution system after the water purifier.
6. CAUTION: As with any water handling device, the water purifier should be located in an area where any possible
condensation or leakage from the water purifier, any purifier accessory and/or plumbing will not result in damage to the
area surrounding the water purifier. For added protection, it is recommended that a suitable drain pan be installed under the
purifier. The drain pan must be plumbed to an adequate, free flowing drain to prevent water damage in event of a leak. There
are numerous leak detection/flood stop devices, available on the market today, designed to stop flow 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 purifier 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 reduces the chance of the purified water being re-contaminated by
bacteria in any of these units.

SAFETY EQUIPMENT REQUIRED TO PERFORM TASK
1. Remove water purifier from shipping carton. Inspect water purifier, power cord and plug for damage. Do not operate if there
is any damage to the purifier, power cord or plug. All models, of the MINIPURE®line of water purifiers, are shipped with
the lamps packed separately. Keep the lamp aside for installation once the purifier 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 purifier 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 purifier 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 purifier.
3. The water purifier should be mounted horizontally on a flat dry surface. The purifier should not be solely supported by its
plumbing connections. Securing the water purifier using the optional wall bracket kit is recommended.
4. The water purifier must be connected to the cold water line only. Inlet water temperature should not exceed 100o F.
5. It is recommended that a 5-micron sediment filter be installed, in line, prior to the water purifier. The sediment filter will
stop or trap large particulates from entering the water purifier. Particulates may cause damage to the quartz sleeve, as well as
interfere with the purifier’s ability to disinfect the water. The sediment filter 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 purifier. The use of bypass valves is not
recommended. The shut off valves allow the purifier 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 purifier; this will allow easy removal of the water purifier
from the plumbing, if required. Apply Teflon®tape to threads of inlet and outlet ports to ensure a tight seal.
8. When all plumbing connections are complete, allow water to enter the water purifier at a low flow rate, until the purifier is
full. NOTE: Close the purifier outlet valve to pressurize the chamber. With the purifier pressurized, it should be checked
for leaks. Once it is determined that there are no leaks, the inlet valve can be fully opened.
Figure 3 - 120v and 220v 50/60Hz (ballast no. 10-0508B and 10-0504B)
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)
WARNING: To insure proper operation and safety of your water purifier, your unit must be grounded
to a known good ground.
CAUTION: Lamp and quartz sleeve are easily damaged. Exercise care when handling.

8
1. 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 qualified
Electrician.
2. Once the plumbing hook ups are made, it is a good practice to disinfect the “downstream” plumbing between the purifier and
point of use. This is done by introducing chlorine or other disinfectant solution directly into the purifier chamber, a 100-
ppm of chlorine is suggested. With the disinfectant solution in the purifier chamber, turn the ultraviolet purifier 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 purified 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 flushed through the pipes.
CAUTION: For added protection, a suitable drain pan must be installed under the purifier. The drain pan must be
plumbed to an adequate, free flowing drain to prevent water damage in the event of a leak. There are numerous leak
detection/flood stop devices, available on the market today, designed to stop the flow 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. Sentry™ 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 audio alarm and/
or solenoid valve.
2. Audio Alarm: Activated by the Ultraviolet Monitor or Safety Sensor, alerts the user to any malfunction detected.
3. 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 flow through the water purifier. The time delay mechanism is used in conjunction with,
and is electrically connected to the Solenoid Valve.
4. Solenoid Valve: Operated in conjunction with the Ultraviolet Monitor, Safety Sensor or Time Delay Mechanism, this valve
prevents water flow through the water purifier when an abnormal condition is detected or in the event of power failure.
5. Sure Flo™ Flow Control Valve: Limits water flow to the rated capacity of the purifier. The flow control valve is located
in line prior to the water purifier, and should be protected from ultraviolet exposure by the use of a 90-degree elbow fitting
between the flow control valve and the water purifier. Unless otherwise specified PVC flow control valves are supplied.
Stainless Steel Flow Control Valves are available for certain models. All PVC and Stainless Steel flow control valves are male
NPT. Consult Factory for other flow control valves
6. Elapsed Time Indicator: A non-resettable display of the water purifier operating hours. Useful for scheduling and recording
maintenance and lamp replacement.
7. Safety Goggles: Safety eyewear should be used as general-purpose safety protection and for additional shielding from
Ultraviolet rays
8. Gloves: Gloves should be worn to offer hand protection from sharp threats like glass, wire, and metal.
NOTE: The recommended options above are available from Atlantic Ultraviolet Corporation or a distributor of Atlantic
Ultraviolet Corporation’s 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 purifier 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 often false 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 purifier. If you encounter difficulty 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 purifier if it will be subjected to
temperatures below freezing.
• Contact factory with questions.
INSPECTION
1. Regularly inspect the water purifier 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 purifiers so equipped, the SentryTM Safety Sensor provides visual indication of ballast and ultraviolet lamp operation
2. To ensure proper operation of the water purifier, regular biological testing should be performed on a schedule recommended
by local public health authorities, or at minimum; at installation, quarterly for the first year of service and annually, at lamp
replacement, for the life of the water purifier.
3. Additional testing should be performed whenever modifications, 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 purifier installation, routine maintenance is necessary to insure your equipment is operating correctly.
Regular inspection must also include the inspection of the ground to insure grounding wires are secure to both the water
purifier and grounding point as originally installed. Regular inspection must also include confirmation that approved ground
fault circuit interrupt (GFCI) receptacle is still operational and that water purifier is plugged into this GFCI. Any components
which are damaged, or broken should be replaced.
BREAKAGE
CAUTION: Broken Quartz is SHARP.
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.

6. CAUTION: 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 purifier vertically and shake. The quartz fragments will break and drop out
of the purifier through the gland fitting. 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 fitting of the chamber.
10. Carefully slide the quartz sleeve into the chamber, guiding it through the gland fitting. 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 finger through the far end
gland fitting and into the quartz sleeve. This will minimize the possibility of breaking the quartz sleeve as it passes through
the gland fitting.
12. Center the quartz sleeve in the chamber, making sure the quartz sleeve protrudes an equal distance past each threaded gland
fitting, of the chamber.
13. Re-install o-rings, Teflon®washers, and static gland nuts. Be sure o-rings are placed on quartz sleeve before Teflon®washer.
Tighten static gland nuts firmly 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 purifier at a low flow rate until the purifier is pressurized.
With the purifier pressurized, it should be checked for leaks.
15. If no leaks occur, reinstall lamp, following the steps in “LAMP INSTALLATION OR REPLACEMENT” section.

WARNING: The equipment that this ballast is used with requires connection to a known good ground. It is the User’s
responsibility to insure 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 qualified, licensed electrician.
Failure to comply with this requirement could result in serious injury or death.
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.
