Notes:
1. All electrical installation must be in accordance with national and local electrical codes and job wiring schematic.
External wiring options - see IM for the different configured options, wiring to be minimum 18 gauge, 90°C.
3. EC motors are factory programmed for specified air flow. Contact Daikin Applied for replacement.
4. Cap extra wire. Switch wire 42A to red wire for 208V operation.
5. Switch wire 509 to terminal 2 for 208V operation.
6. Devices in legend may or may not be on unit.
