PRODUCT APPLICATION
ConstruCtion
• These units have been designed to be CE compliant. These units have been tested to and comply with the requirements of
the Electromagnetic Compatibility Directive and the Machinery Directive. The Declaration of Conformity lists the European
Norm (EN) standards to which these units were tested, to demonstrate conformity.
• The water purier is designed to mount horizontally.
• The water purier’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.

• The water purier’s removable chamber head design facilitates the ease of maintenance (SANITRON®moDel s37C only).
• A drain port on the chamber aids in draining of the purier.
• The dual action wiper mechanism allows for quick and easy quartz sleeve cleaning, without interrupting service.
(SANITRON®moDel s37C only)
PrinCiPle of oPeration
The SANITRON®/ 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 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 SANITRON®/ MIGHTY«PURE®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 translucent sight port, or optional ultraviolet monitor, provides visual indication of germicidal lamp operation.
• Water leaving the purier is instantly ready for use, no further contact time is required.
• The dual action wiper mechanism facilitates periodic cleaning of the quartz sleeve without disassembly or interruption of
purier operation. (SANITRON®moDel s37C only)
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 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. Plug water purier only into an approved ground fault circuit interrupt (GFCI) receptacle.
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 wiper 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.

installation
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. Units are shipped with their 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 or
Replacement” in the “Maintenance” section for the proper method of replacing the quartz sleeve in your water purier.
Figure 2 - Recommended Installation
3. The water purier should be mounted horizontally on a at dry surface. Secure the water purier using the mounting holes
in the ballast housing or with the optional wall mounting kit. The purier should not be solely supported by its plumbing
connections.
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 that a 5-micron sediment lter or ner 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.
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. For Models with lamps packed separately, install lamp following the steps in “Lamp Installation or Replacement” section.
Lamp and quartz sleeve are easily damaged. Exercise care when handling.

10. Plug water purier into approved ground fault circuit interrupt (GFCI) receptacle. Conrm 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 purier
and point of use. This is done by introducing chlorine or other disinfectant solution into the purier chamber, a 100-ppm of
chlorine is suggested. With the disinfectant 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 three (3) hours. Flush the plumbing with ultraviolet puried water; allow the water to run for a minimum of 5
minutes prior to use (to ensure no chlorine or disinfectant smell can be detected). This will allow the chlorine or disinfectant
solution to be ushed from the pipes.
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 purier. The ultraviolet monitor is capable of operating an optional Promate™ Audio
Alarm and/or Promate™ 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 Promate™ Audio
Alarm and/or Promate™ Solenoid Valve.
3. STERALERT™ Lamp Status Alarm: Produces a high pitched, pulsed tone when the water purier is no longer functioning
when visible light fails.
4. SureFLO™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.
5. Promate™Audio Alarm*: Activated by the Ultraviolet Monitor or Safety Sensor, alerts the user to any malfunction detected.
6. Promate™Solenoid Valve*: Operated in conjunction with the 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.
7. Promate™Elapsed Time Indicator: A non-resettable display of the water purier operating hours. Useful for scheduling and
recording maintenance and lamp replacement.
8. Promate™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 Promate™ Solenoid Valve.
9. Promate™Wall Mount Kit: Stainless steel wall brackets provide quick and easy installation and professional nish. 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
purier’s disinfection chamber. Since the 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. Promate™Safety Goggles: Safety eyewear should be used as general-purpose safety protection and for additional shielding
from ultraviolet rays
12. Promate™Face Shield: Adjustable headgear and lightweight visor provides eye and face protection from
germicidal ultraviolet rays.
* Use of this option is recommended by U.S. Public Health Service “Criteria for Acceptability of an Ultraviolet Disinfection Unit.”
Originally issued April, 1966.
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. NOTE: SANITRON®Ultraviolet water purifiers are equipped with
a manual wiping mechanism making the process of routine cleaning easier and therefore, recommended weekly or at
the very least monthly to insure your performance. 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 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.
• On puriers not equipped with the Ultraviolet Monitor, lamp operation can be veried 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 puriers so equipped, the GUARDIAN™Ultraviolet Monitor provides visual indication of the ultraviolet intensity
through the quartz sleeve and water in the purier chamber.
2. To ensure proper operation of the water purier, regular biological testing of the purier output 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 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.

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 purier chamber.
• On MIGHTY«PURE®Models MP36C, the ballast housing is mounted to the purier 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 at 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 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.
3. 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 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.
5. Carefully discard all pieces of the broken quartz sleeve.
6. Align the end of the replacement quartz sleeve with the gland tting of the chamber.
7. 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 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 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.
9. Center the quartz sleeve in the chamber, making sure the quartz sleeve protrudes an equal distance past each threaded gland
tting, of the chamber.
10. 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.
11. Re-assemble ballast housing to purier chamber, using hardware removed in Step 1. NOTE: When re-assembling ballast
housing to purier 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 purier at a low ow rate until the purier is full. With the
purier pressurized, it should be checked for leaks.
13. See “Lamp Installation or Replacement” section to properly re-install the lamp into the water purier.

EQUIPMENT: SAFETY GOGGLES OR A FACE SHIELD, AS WELL AS GLOVES
Broken Quartz is SHARP. It is recommended that protective goggles and gloves are worn when handling.
Disconnect power to water purier. Shut off water supply to water purier via inlet and outlet shut-off
valves. Completely drain chamber.
Follow the steps in “Quartz Sleeve Installation 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 purier chamber.
• On SANITRON® Models S37C the ballast housing is mounted to the purier 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 at
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. Carefully remove as much of the broken quartz sleeve as possible, from each end of the chamber.
3. Remove chamber head clamp, by using a 7/16” wrench to loosen and remove the 1/4” nut from the head clamp
4. Withdraw chamber head and wiper assembly, from the chamber.
5. Any broken pieces of the quartz sleeve can now be removed through the open end of the purier chamber. Flush water through
chamber being careful to remove all quartz fragments from the interior of the chamber.
6. Carefully discard all pieces of the broken quartz sleeve.
7. Inspect the large O-Ring used to seal the chamber and the chamber head. Make sure the O-Ring is seated properly between the
chamber head ring and the are of the chamber head.
8. Insert replacement quartz sleeve through each Teon®wiper segment, starting from the furthest segment working towards the
chamber head. Twisting the quartz sleeve will help work the quartz sleeve through the Teon®segments. Align the end of the
quartz sleeve with the threaded gland nipple of the chamber head, and pass the quartz sleeve through the chamber head.
9. To re-install, carefully slide the chamber head and wiper rod assembly, into the chamber, with drain port pointing down; using
your nger, support the far end of the quartz sleeve when passing it through the gland tting of the chamber. Push chamber
head ange into the chamber until ared end, of the chamber and the head, mate against the O-Ring.
10. Replace the head clamp around the ared end of the head and chamber. Install the 1/4” nut and tighten, using a 7/16” wrench,
until approximately 3/4” to 7/8” of the bolt protrudes past the nut.

oPtional guarDiantm ultraviolet monitor sensor ProBe Cleaning
Figure 7 - Ultraviolet Monitor and Sensor Probe Figure 8 - Sensor Probe
If after cleaning the quartz sleeve, there is no signicant 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 tting, located in the
center of the disinfection chamber, and protrudes into the chamber.
1. Disconnect power to water purier.
2. Shut off water supply to the water purier via the inlet and outlet shut-off valves. Remove drain plug and drain the chamber.
Once the chamber is drained, remove any old sealing tape from the threads of the drain plug, rewrap with 1/2” wide Teon®
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 ngerprints 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 tting of the chamber and hand tighten.
10. Slowly restore water supply to the water purier, pressurize, and check for leaks. Once it is determined that there are no
leaks, inlet valve can be fully opened. (Continued on Page 15)
