Daikin Cassette additional connections

[sgge888]

Does anyone know where you can find out how these affect overall unit duty

I have two 10kw cassettes in a room which is over duty as its now two rooms. The 'new' smaller room next door is now too hot.
Client doesnt want to move a cassette so I suggested connecting onto cassettes to pull off air to condition warmer area. I have seen this done a few times but was wondering if there was a
manual which shows duty loss on cassette depending on duct size.

Thanks in advance

If the 10kW cassette was correctly sized when it was just 1 room, I don't think you would have any duty loss if you were to duct off to the new room to serve a grille.

Don't forget to allow for return air though.
