Description, Features & Benefits
The Viqua UVMax Model F4-50+ has been specially designed for water sources with known clarity and UVT problems. The F4-50+ effectively disinfects water with UVT values as low as 50% at flow rates up to 12 gallons per minute while providing the added peace-of-mind of a real time UV intensity monitor.
Viqua UVMax F4-50+ UV sterilizer is a popular choice for larger homes with 3 to 5 bathrooms. It is designed to treat bacteria (such as e.coli and coliform), viruses, and other microbiological contaminants including giardia (beaver fever) and cryptosporidium without the use of chemicals. It is suitable for the treatment of private wells and surface water supplies, as well as municipal water for those seeking a higher level of confidence in the safety of their water supply. The F4-50+ provides a UV dose of no less than 40 mJ/cm2 for flow rates up to 12 gallons per minute (based on a UVT level of 50% and at the end of lamp life).
The F4-50+ features a real time UV intensity monitor which monitors the feed water quality and UV sleeve clarity to ensure that your system is able to safely disinfect your water. If conditions change and the system is no longer able to ensure safe treatment of your water, an alarm will sound. The use of a model with a UV intensity monitor is generally recommended where a known E.coli or other serious problem is present or the feed water parameters may cause problems with UV tramsmittance from time to time (sediment flushing, iron or hard water scale build-up on the UV sleeve etc.). The Viqua F4-50+ is able to monitor water with low UVT transmittance that would cause constant alarms on typical systems with UV intensity monitors which are usually calibrated to alarm at higher UVT levels.
The UVMax F4-50+ is manufactured by Viqua, the residential and light commercial division of Trojan Technologies, the world leader in UV water disinfection technology. Viqua has the largest installed base of UV sterilizers in the world spanning some 600,000+ systems. Trojan is ISO9001:2008 registered and has more than 800 employees in 8 countries. Like all Viqua systems, the F4-50+ is manufactured in Canada and uses UV lamps custom-manufactured in the USA.
Key to the long-standing popularity of the UVMax product line is its brand reputation, feature-rich controller, and no-tools maintenance. The high output lamp results in a system with a very compact size relative to its treatment capacity, and its constant current power supply ensures a uniform UV dose even when the source power supply fluctuates. The LCD display ensures all important system information is available at a glance.
UV disinfection is safe, effective, economical, and best of all, does not add undesirable chemicals to your water like chlorine or chloramine.

Why UV? - UV Advantages
UV water treatment offers many advantages for the treatment of microbiological contaminants like bacteria (including coliform and e.coli), viruses, molds, algae, yeast, and oocysts like cryptosporidium and giardia. Every year, these contaminants are responsible for thousands of serious illnesses due to the failure of city treatment plants or consumption of untreated well or surface water.
Unlike other disinfection options, UV sterilizers do not add any chemicals to the water, do not produce harmful by-products (THMs and HAs), and do not alter the taste, pH, mineral content, or other properties of the water. Accordingly, in addition to producing safe drinking water, UV disinfection is not harmful to your plumbing and septic system. Furthermore, it is easy and cost-effective to install and maintain without any special training.
UV sterilizers are one of the most popular and respected water treatment technologies in use today. They can be found in a wide range of water treatment applications ranging from simple under sink water filters to huge city water treatment plants.
- Treats bacteria including coliforms and e.coli
- Treats very wide range of harmful viruses
- Inactivates cryptosporidium and giardia
- Absolutely no chemicals added
- No disinfection by-products
- Doesn't change taste or smell
- Just clean the sleeve and replace the lamp once per year (or 2)
- No tools maintenance
- Low operating cost
With the infrastructure of cities all over North America crumbling under neglect and budget constraints, many customers have asked us if there was a product that they could add to their water system that would provide them with additional insurance and peace-of-mind against the possibility of a failure of their municipal water treatment system. These concerns have arisen due to several high-profile cases of contamination in city water supplies across the continent, some of which have resulted in illness and even death. UV disinfection is a great option to provide this extra level of insurance in your water supply.

Minimum pre-filtration shall consist of a 5 micron sediment filter. All UV sterilizers require sediment pre-filtration to reduce or eliminate the possibility that a targeted contaminant could "hide" behind a sediment particle in the "shadow" of the UV light and therefore not receive a full dose of UV light. Accordingly, the manufacturer strongly recommends sediment pre-filtration down to a level of 5 microns or smaller.
Water exceeding 120 ppm in hardness (7 grains per gallon) should be softened or treated with a salt-free hard water conditioner to reduce the risk that hard water mineral scale will build-up on the UV sleeve thereby reducing UV light distribution into the UV chamber. Similarly, iron levels exceeding 0.3 ppm (mg/l) or manganese levels exceeding 0.05 ppm (mg/l) should also be treated to prevent staining of the UV sleeve.
Elevated levels of certain other contaminants, such as tannins, can cause a reduction in UV transmittance (the ability of the water to transmit UV light). If the UV transmittance (UVT) of your water is less than 50% after the above-mentioned pre-treatment, activated carbon or ion exchange filtration may be desirable to improve UV transmittance.
We recommend that you have your water tested for the following parameters before selecting a UV sterilizer. Proper pre-treatment to ensure that your water meets these parameters will maximize the performance of your UV system. It will also reduce your maintenance requirements. If your conditions do not meet these parameters, please call us toll free at 1-866-376-2690 to discuss pre-treatment options or to discuss how the performance of your UV system will be affected.

How Ultraviolet (UV) Disinfection Works
UV sterilizers are an innovative technology that kills bacteria, viruses, and other microbiological water contaminants without the use of chemicals.
A great way to think about a UV sterilizer is to consider the effect of ordinary sunlight when we spend too much time outdoors in the sun - we can get a sunburn and our skin can be damaged. UV water disinfection is a similar process except it is dramatically more powerful then sunlight. A special lamp, surrounded by a quartz glass sleeve inside the stainless steel chamber that the water flows through, produces UV light concentrated at a specific wavelength that is most damaging to microorganisms. Inside the chamber, the contaminants are exposed to the UV light which damages their DNA. Once the DNA of the organism is damaged, the microorganism is unable to regulate its functions and reproduction. It either dies or is no longer able to reproduce and cause illness. We call this inactivation.
Just as the extent of your sunburn can vary depending on how much time you spend in the sun and the intensity of the sunlight on a hot summer day, the amount of UV light the contaminants are exposed to determines the effectiveness of the UV sterilizer. This is known as the UV dose. The 2 factors that contribute to UV dose are the exposure time which is directly related to the flow rate of the water through the UV chamber, and the intensity of the UV light is related to the effectiveness and design of the UV lamp and chamber, the age of the lamp, the clarity of the sleeve, and the clarity of the water being treated. We refer to the clarity of the water as UV transmittance or UVT. It is important to note that sometimes water with a high level of organics can appear virtually clear but have poor UVT since many organics can absorb UV light. We recommend that you have the UVT of your water tested.
UV Dose = UV Intensity x Exposure Time (Flow Rate)
To ensure a high UV intensity, it is important that the UV sleeve be cleaned periodically and that the water is properly pre-treated to remove minerals that can foul the UV sleeve (hardness, iron, and manganese). It is also important to pre-treat to remove sediment as well as organics and tannins that could absorb UV light. Pre-filtration to a minimum level of 5 microns is required by all UV manufacturers.
This model is equipped with a special sensor that continuously monitors the intensity of the UV light in the treatment chamber. If the UV intensity ever drops so low that the UV system is no longer able to safely disinfect your water, the system will produce an audible alarm to notify you. If the system is equipped with an optional emergency solenoid shut-off valve (sold separately), the system will also shut your water off. This is an excellent feature to have on systems that are subject to water quality variations or where additional safety is desired (children, elderly, or immune compromised).
As a UV lamp ages, the intensity of the UV light it produces will decline. UV manufacturers test the performance of their UV systems to ensure that they are capable of safely treating the water based on the UV output of their lamp at the end of its stated life. Beyond this point, the UV lamp might still be illuminated, but the specific wavelength of UV light might not be intense enough to safely disinfect the water. This is why it is very important to replace the UV lamp based on the manufacturer's stated lamp life. Most UV lamps have a service life of 9,000 hours or 1 year.
Many of our competitors advertise the capacity of their UV sterilizers based on a dosage of 30 mJ/cm2. We provide this information for comparative purposes, however, we strongly recommend that you size your UV sterilizer based on a dosage of 40 mJ/cm2. This ensures better disinfection when the UVT is less than optimal and provides extra protection against more resistant viruses. See our UV dose chart for a list of UV dosage levels required to treat common bacteria and other pathogens.
With proper pre-treatment and scheduled lamp replacement, UV disinfection is a highly effective and economical means of disinfecting drinking water. It is the most popular disinfection technology for well water and other private water supplies. It is also growing in popularity as a whole house treatment for homes connected to a city water supply as homeowners seek additional assurance that their water supply is safe, especially in light of recent prominent infrastructure failures in the news across the country.
Installation, Manuals & Resources
We recommend that UV sterilizers be installed by a licensed plumber; however, your warranty is valid as long as your system is installed in accordance with local plumbing codes and the manufacturer's Owner's Manual. For a homeowner with basic plumbing experience, the installation of a UV sterilizer is relatively simple.
We generally recommend that all UV sterilizers be installed with the treatment chamber in a vertical position, especially those equipped with UV intensity monitors. However, it is acceptable to install the UVMax F4-50+ horizontally if absolutely necessary. You will need access to a nearby standard electrical outlet to power the unit.
