THE MANUAL BUTTON IS NOW THE PRESSURE
COOK BUTTON IN V3 OF THE DUO (RELEASED
IN JUNE 2018).
IF A RECIPE SAYS TO USE THE MANUAL
BUTTON, JUST USE THE PRESSURE COOK
BUTTON IN V3 OF THE DUO.
DUO v1 & v2 DUO v3
..........................................................................
Instant Pots are made in US quarts. 6 quarts = 5.67
litres (5.67812 to be exact). It was always rounded up
but in v3 of the 6 litre DUO it has been rounded down
so now it says 5.5 L. The inner pot is exactly the same
as before.
5.67812 L just wasn't very catchy.
