7.10 Wiring Diagrams
A series of basic connection wiring diagrams have been provided to
assist on-site wiring. In order to reference the relevant diagrams please
use the code breakdown opposite to determine:
•
Unit size
•
If an electric heater is present
•
If Reverse Cycle DX heating or cooling is present.
The below tables can then be used to reference the required connection
and wiring diagrams.
Example:
Unit onsite has code
B822V/ER/AT-L.
This indicates a size 22 unit with
electric heating and Reverse Cycle DX cooling (Section 7.10.10).
