When attaching FMX QR code labels to exterior equipment, we typically see customers follow these tips:

1. If possible, place the QR code on the inside of an access panel or filter door. There are many types of HVAC equipment (rooftop units or air handling units) and other equipment (chillers or backup generators) that have access doors that can be opened to allow the QR code to be scanned. For consistency, place the QR code in the same place on each type of equipment. For example, for a rooftop air handler, always place the QR code on the inside of the supply air filter access door.

2. If #1 is not possible, place the QR code on the side of the equipment that faces north. This should minimize the amount of direct sunlight and fading on the tag.

3. If the QR code is placed on the north side of the equipment, it is also possible to cover the tag with some type of material such as scrap rubber or wood. The material can be screwed or bolted over top of the QR code, just make sure to leave the fastener a little loose to allow it to be pivoted out of the way for scanning the code.

4. When printing the QR codes, always select "labels" in printing preferences on your laser printer. This allows the ink to be heated a little longer for better adhesion to the label as it is printed.

5. There are several labels that you can use, but we have seen the most success with Avery 94106 1-½" x 1-½" blank square labels purchased with the WEATHERPROOF WHITE FILM material. (This label template is also listed when you export your equipment from FMX.)
