PRODUCT APPLICATION
CONSTRUCTION
• The water purifier is designed to mount horizontally.
• A drain port on the chamber aids in draining of the purifier.
• The water purifier’s chamber and chamber head are passivated and electropolished type 316 Stainless Steel.
• The ballast housing is a combination of Stainless Steel Type 304 and Aluminum Alloy.
• EASY-OFFTM 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 MightyPure®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 MightyPure®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 translucent sight port, or optional ultraviolet monitor, 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: Plug water purifier only into an approved ground fault circuit interrupt (GFCI) receptacle.
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.

INSTALLATION
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. Models MP16A through MP22A are shipped with the lamp already
installed, while the lamp in the MP36C and MP49C is 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. Secure the water purifier using the mounting holes
in the ballast housing or with the optional wall mounting kit. The purifier should not be solely supported by its plumbing
connections.
4. The water purifier must be connected to the cold water line only.
5. Installation requires that a 5-micron sediment filter or finer 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.
9. For Models with lamps packed separately, install lamp following the steps in “Lamp Installation or Replacement” section.
CAUTION: Lamp and quartz sleeve are easily damaged. Exercise care when handling. (Continued on Page 7)
Figure 2 - Recommended Installation

10. CAUTION: Plug water purifier into approved ground fault circuit interrupt (GFCI) receptacle. Confirm lamp operation
indication at sight port.
11. 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.
INITIAL INSTALLATION OF QUARTZ SLEEVE MODEL MP49C
(SHIPPED WITHOUT QUARTZ SLEEVE INSTALLED)
SAFETY EQUIPMENT REQUIRED TO PERFORM TASK
WARNING: Water Purifier should NOT be installed or plumbed prior to following the instructions on this page.
NOTE: Some MightyPure®Model MP49C models are packed without a quartz sleeve installed in the water purifier chamber
and instead have a PVC pipe installed temporarily (for shipping purposes). Please follow these instructions if applicable.
1. Pull off Easy-Off™end caps from static gland nut on each end of the water purifier chamber.
2. Unscrew static gland nuts from each end of the chamber and remove Teflon®washer and o-ring from both ends of PVC pipe.
Set aside.
3. Remove PVC pipe and discard (REMINDER: be sure that the Teflon®washer and o-ring from both ends of PVC pipe are
removed before discarding)
4. CAUTION: Broken Quartz is SHARP. It is recommended that protective goggles and gloves are worn when
handling. Remove quartz sleeve from separate package inside the carton which had contained the water purifier.
5. Align the end of the quartz sleeve with the gland fitting on the chamber (the quartz sleeve can be inserted into the chamber
from either end of the water purifier chamber).
6. Carefully slide the quartz sleeve into the chamber guiding it through the gland fitting. Make certain the quartz sleeve is
aligned in the center of the chamber. Do not force the sleeve sideways. This will result with the quartz sleeve breaking.
7. As the quartz sleeve nears the far end of the chamber, guide and support the quartz sleeve by inserting your finger through
the far end gland fitting and into the end of the quartz sleeve. This will minimize the possibility of accidental breakage as the
quartz sleeve passes through the gland fitting.
8. Center the quartz sleeve so equal lengths are protruding at each end past the gland fittings.
9. Reassemble the o-rings (Figure 3), Teflon®washers (Figure 3) and gland nuts (Figure 3) in the order shown in Figure.
TAKE CARE NOT TO DAMAGE THE QUARTZ SLEEVE WHEN INSTALLING THE GLAND NUTS. STRIKING THE
SLEEVE WITH THE GLAND NUT WILL BREAK THE END OF THE QUARTZ SLEEVE.
10. Tighten the static gland nuts firmly by hand. DO NOT USE HAND TOOLS. Using hand tools is likely to cause quartz
sleeve to break.
11. Proceed to the Lamp Installation or Replacement section of this manual to properly install the germicidal ultraviolet lamp in
the water purifier.

RECOMMENDED OPTIONS
1. Guardian™Ultraviolet Monitor: Visually indicates the level of germicidal ultraviolet energy that penetrates the quartz
sleeve and the water within the water purifier. The ultraviolet monitor is capable of operating an optional audio alarm and/or
solenoid valve. The ultraviolet monitor will detect reduction of ultraviolet levels due to:
• Fouling or deposits on the quartz sleeve.
• Poor ultraviolet transmission through the water; color, turbidity, and organic or other impurities in the water can reduce
or interfere with the transmission of ultraviolet rays.
• Lamp outage or component failure. (Monitor will not function in power outage.)
• Depreciation of the lamp output due to usage or other cause. Lamp output gradually depreciates with use. Lamp
replacement is recommended once each year.
2. 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.
3. Steralert™:Lamp Status Alarm produces a high pitched, pulsed tone when the water purifier is no longer functioning due to
lamp or power failure.
4. 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.
5. Audio Alarm: Activated by the Ultraviolet Monitor or Safety Sensor, alerts the user to any malfunction detected.
6. 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.
7. Elapsed Time Indicator: A non-resettable display of the water purifier operating hours. Useful for scheduling and recording
maintenance and lamp replacement.
8. 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.
9. Wall Mount Kit: Stainless steel wall brackets provide quick and easy installation and professional finish. Pre-drilled and
ready to install. Optimizes free air circulation to cool ballast housing.
10. Quantum Thermal Optimizer: Thermal relief valve used to help regulate the water temperature inside the water purifier’s
disinfection chamber. Since the relative ultraviolet output, of a germicidal lamp, is affected by temperature it is important to
keep the lamp’s temperature within the peak output temperature range.
11. Safety Goggles: Safety eyewear should be used as general-purpose safety protection and for additional shielding from
Ultraviolet rays
12. 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. NOTE: The use of optional Guardian™ Ultraviolet Monitor
will detect loss of transmission due to coating on the quartz sleeve.
• 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.
• On purifiers not equipped with the Ultraviolet Monitor, lamp operation can be verified by a visible glow through the
translucent sight port. This provides an indication of lamp operation and does not indicate the level of ultraviolet
intensity or transmission through the water.
• On purifiers so equipped, the Guardian™ Ultraviolet Monitor provides visual indication of the ultraviolet intensity
through the quartz sleeve and water in the purifier chamber.
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 ensure your equipment is operating correctly.
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.
DISPOSAL OF MERCURY ADDED LAMPS
Germicidal ultraviolet lamps, like standard fluorescent lamps contain small amounts of mercury. Mercury added lamps
should not be placed in the trash. Dispose of properly. For further information regarding the disposal and recycling of
lamps containing mercury, along with Federal and State requirements visit http://www.lamprecycle.org. Product Data

REPLACEMENT OF BROKEN QUARTZ SLEEVE
SAFETY EQUIPMENT REQUIRED TO PERFORM TASK
CAUTION: Broken Quartz is SHARP. It is recommended that protective goggles and gloves are worn when handling.
WARNING: Disconnect power to water purifier. Shut off water supply to water purifier via inlet and outlet shut
off valves. Drain chamber by removing drain plug.
Follow the steps in “Quartz Sleeve Installation, Cleaning or Replacement” to remove lamp and quartz sleeve.
1. To prevent damage to the electrical components, it is necessary to separate the ballast housing from the purifier chamber.
• On MightyPure®Models MP16A, and MP22A, the ballast housing is mounted to the purifier chamber using four (4)
No. 8 x 3/8” long screws. Using a Phillips cross point screwdriver, carefully remove the four (4) screws, from along the
sides of the ballast housing, and set aside. Separate the housing from the chamber.
• On MightyPure® Models MP36C, and MP49C , the ballast housing is mounted to the purifier chamber using four (4)
1/4”-20 x 3/8” long hex head bolts. Using a 7/16” wrench or an adjustable wrench, carefully remove the four (4) bolts
with the lock and flat washers, from along the top of the ballast housing, and set aside. Separate the housing from the
chamber.
• Keep ballast housing and mounting hardware in a clean, dry area.
2. Unscrew static gland nuts from each end of the chamber. Remove Teflon® washer and o-ring from both ends of quartz sleeve.
Teflon® washer will sometimes remain within the static gland nut. If so, remove Teflon®washer from static gland nut before
proceeding.
3. CAUTION: Carefully remove as much of the broken quartz sleeve as possible, from each end of the chamber.
4. 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.
5. Carefully discard all pieces of the broken quartz sleeve.
6. Align the end of the replacement quartz sleeve with the gland fitting of the chamber.
7. 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 the chamber. Angling the quartz sleeve in any direction could result in the breakage of the quartz sleeve.
8. 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.
9. Center the quartz sleeve in the chamber, making sure the quartz sleeve protrudes an equal distance past each threaded gland
fitting, of the chamber.
10. 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.
11. Re-assemble ballast housing to purifier chamber, using hardware removed in Step 1. NOTE: When re-assembling ballast
housing to purifier chamber, electrical power cord should exit ballast housing from the end mounted opposite the drain plug.
12. When all connections are complete, allow water to enter the water purifier at a low flow rate until the purifier is full. With the
purifier pressurized, it should be checked for leaks.
13. See “Lamp Installation or Replacement” section to properly re-install the lamp into the water purifier.

If after cleaning the quartz sleeve, there is no significant improvement in the ultraviolet intensity, as shown on the intensity meter,
it may be necessary to clean the Ultraviolet Monitor’s sensor probe. The sensor probe body mounts in a fitting, located in the
center of the disinfection chamber, and protrudes into the chamber.
1. WARNING: Disconnect power to water purifier.
2. Shut off water supply to the water purifier via the inlet and outlet shut off valves. Drain the chamber by removing the drain
plug. Once the chamber is drained, remove any old sealing tape from the threads of the drain plug, rewrap with 1/2” wide
Teflon®thread sealing tape, reinstall and tighten the drain plug.
3. Disconnect power to the Ultraviolet Monitor; remove from chamber by loosening the two set screws on the aluminum collar
and lifting it free from probe body.
4. Unscrew the sensor probe and remove from the chamber.
5. Remove the quartz rod sensor probe cap, from the probe body. Take care not to damage the quartz rod, o-ring or the threads
of the probe body. NOTE: It is recommended, when servicing the sensor probe, to work in a clean, dry area.
6. Once the quartz rod is removed, clean with alcohol or a mild detergent, and rinse with clean water. Stubborn stains usually
can be removed with a dilute hydrochloric acid. NOTE: Follow all manufacturer’s instructions and precautions when
handling chemicals. Once the quartz rod has been cleaned, handle the rod by the sides, to avoid getting fingerprints on the
quartz rod faces.
7. Clean the probe body, by removing any dirt or deposits on all surfaces. o-rings should be inspected and can be replaced if
worn or damaged.
8. Reassemble, replacing the o-rings, quartz rod and securing in place with the quartz rod sensor probe cap. Tighten the quartz
rod sensor probe cap by hand only, DO NOT USE HAND TOOLS. Tightening with hand tools may damage the quartz rod
or o-ring seal.
9. Reinstall sensor probe into the center fitting of the chamber and hand tighten.
10. Slowly restore water supply to the water purifier, pressurize, and check for leaks. Once it is determined that there are no
leaks, inlet valve can be fully opened.
11. Reposition Ultraviolet Monitor on probe body and tighten set screws.
12. Restore power to the water purifier and ultraviolet monitor. If after the cleaning of the quartz rod, there is still no significant
improvement in the ultraviolet intensity, as shown on the intensity meter, proceed to the “Troubleshooting” section.
