Connect the main supply to the outdoor unit and make the connection as shown in the diagram below:
The connection cable on indoor units must be connected to the corresponding terminal block. If not, this will cause
the unit to malfunction or may even damage the equipment.
- The diagram above is just one example of 5x1 outdoor units connected. Wall-mounted, ceiling-
mounted/consoles, cassettes and ductable units can be connected to any terminal on the outdoor unit.
- Ensure that the earth wire is connected correctly, to avoid the risk of certain electrical components
malfunctioning and to avoid causing a shock or a fire.
- Do not reverse the polarity.
