Have the CY1B and CY1S already completed a model change?
CY1B/CY1R series has changed to CY3B/CY3R. CY1S series has changed to CY1S-Z. The conventional CY1S had only the centralized piping type and CY1S-Z shall be the bilateral piping type without any additional symbol on model type. Please note that G type should be selected for the centralized piping type.
