UV Radiation Safety

IMPORTANT SAFEGUARDS
READ AND FOLLOW ALL SAFETY INSTRUCTIONS

This equipment is designed for use with germicidal UV radiation sources and must be installed in compliance with competent technical directions to prevent risk of personal injury from UV radiation.

UV radiation can pose a risk of personal injury. Overexposure can result in damage to eyes and bare skin. To reduce the risk of overexposure this equipment must be installed in accordance with the manufacturer’s site planning recommendations. This may include instructions on the relative location of each germicidal system component, the minimum distances between UV-generating devices and other objects or surfaces, and protection from line-of-sight exposure to UV radiation in occupied spaces located above the equipment mounting area (e.g. upper floor balconies, open staircases, etc.).

UV and optical radiation can be reflected by surrounding surfaces such as ceilings and walls. Since the reflective properties of surfaces can vary widely, it should be considered as part of site planning. Follow the manufacturer’s recommendations for selecting appropriate ceiling and wall finishes.

IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT PERSONS WILL NOT BE EXPOSED TO EXCESSIVE UV OR OPTICAL RADIATION DURING EQUIPMENT OPERATION. THIS WILL REQUIRE THE INSTALLER TO CONDUCT AN ASSESSMENT OF IRRADIANCE OR ILLUMINANCE LEVELS IN THE SURROUNDING OCCUPIED SPACES PRIOR TO OCCUPANCY.

Equipment should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel.

Maintenance and servicing of this UV generating equipment shall be performed by authorized personnel. Service personnel must wear appropriate Personal Protective Equipment (PPE) if the equipment will be in operation during the maintenance or servicing work. Contact the equipment manufacturer for PPE recommendations and guidance.

When replacing UV light source, replace them only with the UV light source for which the equipment is marked and intended.

The use of accessory equipment not recommended by the manufacturer may cause an unsafe condition.

Do not use this equipment for other than intended use.

Installation Safety & Disclaimer

Installation and servicing of this product should be performed only by a qualified service personnel. 

DO NOT INSTALL THIS EQUIPMENT IN A DWELLING. 

WARNING: Risk of personal injury. Never touch or clean glass surface of Far-UVC Lamp when the device is energized. Always turn off power and allow device to cool for 15 minutes before touching, cleaning, or servicing Far-UVC lamp.

CAUTION: Do not use abrasive materials, harsh cleaning agents, chemical cleaners, or other solvents on cover plate or lens. Use of these substances may cause the damage to the product. For cleaning purpose, use a mild window cleaning agent such as Windex and a soft non-abrasive anti-static microfiber cloth to gently wipe down the glass surface.

CAUTION: RISK OF PERSONAL INJURY. THIS EQUIPMENT IS DESIGNED FOR USE WITH GERMICIDAL LAMPS OR UV SOURCES AND MUST BE INSTALLED IN COMPLIANCE WITH COMPETENT TECHNICAL DIRECTIONS TO PREVENT THE USER’S EYE AND BARE SKIN FROM OVEREXPOSURE TO HARMFUL UV OR OPTICAL RADIATION. 

This equipment emits UV radiation at wavelengths less than 250 nm which can generate ozone. Take precautions to ensure that the concentration of ozone in the installation is limited to a value that is within applicable permissible exposure limits.

Verify acceptable ozone concentrations in the installation taking into account the number of products in a given volume of space, the characteristics of the ventilation system, access, and other factors. Permissible exposure limits vary based on the place of ozone application, the length of exposure, and other factors and are publicly available.

When replacing equipment, replace only with the lamps for which the equipment is marked and intended. USE ONLY Lit Part Number: LIT UVC222 Module B1.5 DO for Visium 1 with Diffused Optics and LIT UVC222 Module B1.0 CO for Visium 1 with Clear Optics.

For Visium 1 EMC Models Only: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

The equipment is an EPA regulated pesticide device intended to reduce bioburden in air and on surfaces. Bioburden reduction is a function various factors (including device run time, distance to the Far-UVC light, airflow, room size, and/or other factors) and the level of reduction can and will vary within a specific space.

FDA DISCLAIMER – FOOD AND DRUG ADMINISTRATION STATEMENT: The statements made within this manual have not been evaluated by the U.S. Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

Preinstallation & General Guidelines

Preinstallation Notes

• Please properly plan the placement of your Visium 1 before drilling or cutting any holes.
• Installation should be performed by a licensed electrician.
• All electrical connections must be in accordance with local electrical codes, ordinances, or comply with National Electrical Code (NEC).
• Make sure POWER is turned off at the main circuit breaker box to the location that you are installing the device.
• Refer to the proper section of the guide that corresponds to the mounting option.
• Consult with Lit Thinking Customer Service with any questions.
• Refer to device mounting guideline diagram to ensure proper safety and regulatory compliance.
• Installation of Visium 1 Far-UVC device is a way to enhance air safety in well-ventilated spaces. It is not intended to be a replacement for number of air changes per hour (ACH), proper air ventilation, or proper air flow.
• Visium 1 are intended to be used in spaces with greater than 2 air changes per hour (>2 ACH).
• Installers should note and record each device’s serial number and its corresponding location prior to installation.

To ensure compliance with regulatory and UVC exposure threshold limit values (TLV) set forth by the American Conference of Governmental Industrial Hygienists (ACGIH) and recommended by OSHA, do not install below the minimum height specified in these installation instructions. Please see diagram for reference on p. 10.

1 = Area of >60% Peak Irradiance
2 = Area of >30% Peak Irradiance
3 = Peak Irradiance 

*Irradiance and other technical information are for reference only and are subject to change. This is not a formal specification and does not indicate any warrantied values. Please refer to the UVC lamp’s formal specification sheet for complete details and specification.
