Water on floor by wine chiller- checked operation of wine chiller. Both filters clean. Checked condensate drain and pan, both clean and working. Checked operation of condensate pump. Pump is working. Both pressures and delta T where set to manufacturer specifications. Checked operation of steam humidifier. Humidifier working. Checked humidifier for any leaks. None found. Could not find the source of water being on the floor. The water may have come from condensation from the wine chiller duct work, there was a spot that the insulation had come off of the duct work. Reinstalled insulation. Cleaned up water. Placed a pan under duct work to see if that is where the water is coming from. Water could also have leaked through basement w
