Uv installation guide




















Note: For airborne viral particles, upper-room UVGI systems provide air changes per hour that are similar to the introduction of clean air into the space. Upper-room UVGI has been used for over 70 years to eliminate airborne pathogens. Skip directly to site content Skip directly to page options Skip directly to A-Z link. Section Navigation. Important update: Healthcare facilities. Learn more. To maximize protection from the Delta variant and prevent possibly spreading it to others, get vaccinated as soon as you can and wear a mask indoors in public if you are in an area of substantial or high transmission.

The particles remain in the air, but they are no longer infectious. Crowded spaces, particularly when the health status of occupants is unknown for example, courtrooms, lobbies, homeless shelter sleeping areas.

Areas where it is difficult to stay at least 6 feet apart from others. UVGI is recommended in spaces with insufficient or no mechanical HVAC systems or where adequate natural ventilation cannot be maintained year-round. Spaces must be at least 8 feet tall, but a minimum ceiling height of 8. Upper-room UVGI is not necessary in open-air environments, such as outdoor open-air seating areas.

If the HVAC system allows for efficient filtration or provides outdoor air flow above minimum code requirements, it will remove most airborne virus particles and upper-room UVGI would not add as much benefit. How has UVGI been used in the past? Top of Page. Installation and Maintenance Upper-room UVGI systems are generally custom designed for the space in which they will be used. Systems should be designed, installed, and tested with the help of a qualified HVAC professional or a reputable UV-system manufacturer.

These professionals have the tools and experience to provide an effective and safe system, including proper installation and positioning of the fixtures, code-compliant electrical connections, and training on proper use. A typical room with square feet ft 2 of floor space will generally require two to three UV fixtures. Once installed, the systems require little maintenance. The lamps will need to be replaced once per year, although some manufacturers offer lamps with 2-year replacement schedules.

If the lamps become covered with dust, they can be cleaned when the unit is turned off by wiping with rubbing alcohol. Any time maintenance on the lamps is required or workers need to access areas near the ceiling for example, maintaining lighting fixtures, testing smoke detectors , the UV fixtures should be powered off.

It is also more energy efficient to leave the bulb on constantly. Similar to fluorescent lights, the energy necessary to switch on the UV bulb is high, while functioning energy is low. UV-C will degrade all of the organic material on and within a coil, usually within 30 days or less.

Prior cleaning of the coil is not necessary, and may delay the benefits of UV-C. Installation instructions are available.

Depending on the fixture size and style, installation time can average about minutes per fixture. BUVAS installs from outside your unit—no need to open equipment to get going, or to change the lamp. Simply apply the installation template and follow its directions. Its low voltage meets all codes. The factory must always be involved for infectious disease applications. On existing systems, infestations always exist. Therefore, the best results are obtained when the light is located downstream of and facing the coil.

In this location the user can expect the highest efficacy in eliminating surface coil and plenum , drain pan and airborne microbes. On new systems, it can be placed either up or downstream of the coil and aimed at the coil. UV-C Installation. Installation Manual. How long does installation take?
