Page 13: Connections
Connections INSULATING THE HYDRAULIC CONNECTIONS Insulate all connections vapour diffusion-tight in accordance with the relevant local standards and WATER CONNECTION guidelines. To achieve maximum heat exchanger efficiency, always note and follow the manufacturer's data on the side of the fan coil (flow / return on the heat exchanger). Mixing up the water connections would not impair op- eration, but reduces the heat exchanger efficiency. -
