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 chamber is passivated and electropolished type 316 Stainless Steel.
• The ballast housing is a combination of Stainless Steel Type 304 and Aluminum Alloy.
• Coated chambers are available for uses with special applications, consult Factory.
• Easy-off 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:
1. Water enters the purifier and flows into the annular space between the quartz sleeve and the chamber wall.
2. Suspended microorganisms are exposed to the ultraviolet rays emitted by the germicidal lamp.
3. The translucent sight port, or optional ultraviolet monitor, provides visual indication of germicidal lamp operation.
4. 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
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.
Turbidity: 5 NTU
Manganese: 0.05mg/l
Total Suspended Solids: 10 mg/l
pH: 6.5 - 9.5
Color: None
Hardness: 6 GPG or 102.6 PPM
Iron: 0.3 mg/l

INSTALLATION
LOCATION
1. The water purifier is intended for indoor use only. 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 33F and 100F.
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. Plug water purifier 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.
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 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 regard-
ing leak prevention and/or limiting damages due to leaks, please contact the 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.

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. 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 any 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 cleaning 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 pressurized. 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 installing lamp.
10.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 into the purifier chamber, a 100-ppm solution of chlorine is
suggested. With the chlorine in the purifier chamber, turn the ultraviolet purifier on. Open the “downstream” outlet until a
chlorine odor is noticed. Close the outlet and allow the chlorine to remain in the plumbing for three (3) hours. Flush the
plumbing with ultraviolet purified water; allow the water to run for several minutes before use. This will allow the
chlorine to be flushed from the pipes.

INSTALLATION
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 MP13A through MP22A are shipped with the lamps
already installed, while the MP36C and MP49C lamps are 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
Cleaning or Replacement” in the “Maintenance” section for the proper method of replacing the quartz sleeve in your
water purifier. Figure 2 - Recommended Installation

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, component or power failure.
• Depreciation of the lamp output due to usage or other cause. Lamp output gradually depreciates with use.
Lamp replacement is recommended once each year.
• Use of the Guardian™Ultraviolet Monitor is recommended by the U. S. Public Health Service “Criteria for
the Acceptability of an Ultraviolet Disinfection Unit.”
2. Sentry™Safety Sensor: Pilot lamps provide constant visual monitoring of normal operation. In the event of
power 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. 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.

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 mainte-
nance 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.
• Always disconnect the water supply and completely drain the water purifier if it will be subjected to
temperatures below freezing, for extended periods of time.
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.
LAMP-OUT PROTECTION
On MightyPure™MODELS MP16A, MP22A & MP36C If power is applied to the purifier without a lamp con-
nected to the circuit or if the lamp fails, the purifier ballast's lamp-out protection will prevent the purifier from operating.
If the ballast is plugged-in without a lamp or if the lamp fails, the ballast's lamp-out protection will prevent the
ballast from operating.
To reset:
• Lamp replacement is recommended every 10,000 hours of operation, approximately 12 months of continuous service.
• CONNECT lamp OR REPLACE failed lamp.
• After 2 minutes, plug the ballast back into the outlet receptacle; it should resume proper operation.
The ballast must remain unplugged for two (2) minutes to reset.

1. Disconnect power to water purifier.
2. Shut off water supply to water purifier via inlet and outlet shut off valves. Drain chamber by removing
drain plug. Once the chamber is completely 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. Follow the steps in “Lamp Installation or Replacement” to remove lamp.
CAUTION: Lamp and quartz sleeve are easily damaged. Exercise care when removing or replacing lamp.
4. Unscrew static gland nuts from each end of the chamber. Avoid striking quartz sleeve with static gland nut.
5. Remove Teflon®washer and o-ring from both ends of quartz sleeve. Teflon®washer will sometimes remain with
in the static gland nut. If so, remove Teflon®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 finger 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 Teflon®washer.
9. 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.
10. Slowly restore water supply to water purifier and check for leaks.
11. If no leaks occur, reinstall lamp, following the steps in “Lamp Installation or Replacement” section.
