I've installed a large amount of them paired with Trane's XC95 units. We only offer them when paired with the communicating systems due to the added features. I haven't seen any problems with them other than when customers clean them with water, then reinstall them wet. I always recommend rinsing the honeycombs out with water, then placing everything back into the cabinet with the fan running to dry them out quicker. After three or four hours, you can turn power back on to the Clean Effects unit. Other than making sure they are dry, just make sure the Field Charger doesn't have any bent probes on it before you reinstall it, this can cause you problems. Besides the two non-common issues, I believe they are great!
