My office purchased a new Coway water filter last year and it just next to me 10 feet away (straight line). The moose code (braille code) actually has been trouble me sometimes. I know that must be meaning of hot & cold water however I couldn’t prove it.
Until today finally I able to decode what is the braille code on the Coway water filter. It actually was curved in Korean version of braille code means cold & hot water. It written in Korean not English. So you have to decode using Korean braille code but not English braille code.
Conclusion, the braille code on Coway machine can be used by all non blind people and Korean blind people only.
운수 (on su) = hot water
냉수 (naeng su) = cold water
