If the result of the above calculation exceeds the maximum concentration level then make
similar calculations for the second then third smallest room and so until the result falls short of
the maximum concentration.
Where the installation of a facility results in a concentration in excess of the maximum
concentration level then it will be necessary to revise the system.
Please consult your Daikin supplier.
