Germicidal UV

Upper Air

Commissioning and

Ongoing Maintenance

Measurement Guidelines

November 30, 2020

Before You Begin:

Read and understand this entire guide, the luminaire installation instructions, and any sitespecific documents before attempting to install, commission or operate these luminaires.

Failure to read and follow all provided instructions may result in damage or injury.

It is the responsibility of the installer to ensure that persons will not be exposed to excessive UV radiation during equipment operation. This will require the installer to conduct an assessment of irradiance levels per the instructions listed in this document within the surrounding occupied spaces prior to occupancy and to repeat assessment whenever relamping is completed.

This document applies to following products:

Alkco U2C - Germicidal UV 2x2 Grid Ceiling Mount

Alkco UWL - Germicidal UV Louvered Wall Mount

Premeasurement Actions

• Prior to the installation, Signify recommends 100hr burn-in of the lamps.

Once the burn-in is complete, the lamps will be stable and considered a baseline for commissioning measurement.

1 Failure to complete the 100hr burn-in could result in higher initial readings. The space should never be occupied by humans or pets prior to completing all measurements.

• Make sure you have the latest site documents including latest architectural and electrical drawings, simulated calculation report (if performed), list of surface materials and reflectance values (see Appendix B), site audit notes or previous measurements (if applicable) to compare with the current situation.

• Check if the usage of the space (occupant tasks, hours occupied, etc) is the same as it was when the system was designed. If there is a change, register it.

• Look for obstacles (hanging from the ceiling or higher objects from the floor) that may interfere with the UV-C light, register them.

• Check if there are nearby items (smoke detectors, alarms, projectors, wi-fi routers, etc.) with materials or paint that can be degraded by UV-C and advise the customer.

• Energize luminaires and allow to stabilize for 10 minutes prior to beginning any measurements.

• Thoroughly clean the sensor lens according to sensor manufacturer instructions or with Isopropyl Alcohol before beginning measurements.

• Look for standard luminaires installed in the ceiling directly in the irradiance path that may reflect light into the occupied zone. Signify recommends moving or removing these.

1. ASHRAE GPC 37 (Draft).

Germicidal UV 3

Step 01: Establish Baseline

Figure 1

Figure 1: The detector is raised and lowered to find maximum output (irradiance) of the UV beam for recording output. If allowed, permanent marker on the floor would facilitate repeat measurement. Or use a yard/meter stick between the face of the luminaire and the GUV radiometer’s detector.

Instructions for Measuring

1. Acquire all necessary PPE.

2. Zero the UV meter according to the meter manufacturer’s instructions.

3. Remove the cap and position the sensor 3ft (0.91m) from the center of the upper-room GUV luminaire.

1

4. Point the sensor probe vertically, aiming in the beam of the luminaire, the center of the sensor should be in the center of the UV-C beam.

5. Record the reading in the log book, this is the initial baseline output to be referenced by all future readings after replacement lamps are installed.

6. Repeat steps 1-5 at 6ft (1.83m) from the center of the upper-room GUV luminaire.

7. If measuring during relamping and after initial installation, compare results to baseline measurements. If value is less than baseline reading, take corrective action by cleaning the lamp and fixture. If value is more than baseline reading, make sure proper wattage lamp is being installed. .

1,2

Note: Upon luminaire relamping and/or cleaning, changes to site conditions

(painting, installation of new luminaire in the irradiance path, changing or resurfacing reflective surfaces, installation of obstructions in the irradiance path, etc.) and/or changes to site usage, repeat steps 1-7.

Step 02: Eye Level Safety measurements

Instructions for Measuring

1. Create a grid of measurements on the floor, placing the tripod at an equally-spaced distance

(see table to the right).

2. Place the tripod head at the default 6ft (1.83m) or acceptable eye level for the tasks that take place in the space.

3. Make sure to use the 80° field of view adapter on the detector for these measurements.

4. At each grid point, take five measurements.

• For the first measurement, orient the detector

(normal of the detector surface) horizontally

(pointed at ceiling).

• Next, orient the detector vertically, pointing straight ahead along the typical line of sight for measurements in all directions

(north, east, south, west).

5. Record the location of all measured points, clearly highlight if any measurement is higher than the maximum agreed upon value for the application

(based on the Maximum Permissible UV-C Exposure guidelines in Appendix A).

2 Corrective action needs to be taken and system should not be released for use until measurements are in alignment with

Appendix A dosage recommendations.

• The larger the area, the bigger the distance between measurement points.

• Grid should not align with luminaire layout.

• If a simulated calculation of the space has been provided, the measurement grid may follow the simulated grid points for correlation.

• Reduce grid distance:

- Where multiple luminaire are combining energy 3

- Wherever highly reflective surfaces might be found 4

- At task areas
