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Puredesign 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Pureis 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  
Turbidity:  
5 NTU  
0.05mg/l  
10 mg/l  
6.5 - 9.5  
None  
Manganese:  
Total Suspended Solids:  
pH:  
Color:  
Hardness:  
Iron:  
6 GPG or 102.6 PPM  
0.3 mg/l  
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 should be protected from the elements and  
from temperatures below freezing. The ambient temperature, in the area surrounding the water purifier, should be  
between 33F and 100F.  
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.

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  
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.

RECOMMENDED OPTIONS  
1 . GuardianUltraviolet 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 GuardianUltraviolet Monitor is recommended by the U. S. Public Health Service “Criteria for  
the Acceptability of an Ultraviolet Disinfection Unit.”  
2. SentrySafety 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 GuardianUltraviolet 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PureMODELS 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.

washer from static gland nut before proceeding.  
6.  
7.  
Carefully remove as much of the broken quartz sleeve as possible, from each end of the chamber.  
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.  
9.  
10.  
Carefully discard all pieces of the broken quartz sleeve.  
Align the end of the replacement quartz sleeve with the gland fitting of the chamber.  
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.  
13.  
Center the quartz sleeve in the chamber, making sure the quartz sleeve protrudes an equal distance past each  
threaded gland fitting, of the chamber.  
®
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.  
Re-assemble ballast housing to purifier chamber, using hardware removed in Step 4.  
NOTE: When re-assembling ballast housing to purifier chamber, electrical power cord should exit ballast  
housing from the end mounted opposite the drain plug.  
15.  
16.  
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.  
See “Lamp Installation or Replacement” section to properly re-install the lamp into the  
water purifier.
