Take away approximately 20 Pa if there is a hot water coil on 50CJ. The operating point can be adjusted directly via a built-in voltage regulator. Hence all the air flow/operating pressure combinations are possible, with the values in the table above as the maximum values. C A R R I E R 2 0 1 6 / 2 0 1 7 751
