20/TSA/3500/1107/EN Adjustment CODE DESCRIPTION 1 Control knob 2 Casing 3 Front vane panel 4 Cylinder Throw pattern adjustment The supply air jet is adjusted by changing the position of the cylinder. When you turn the knob clockwise the throw pattern is changes from radial to compact. Pass the tubes and control spindle through the front vane panel. Measure the differential pressure using a manometer. The flow rate is calculated using the formula below. q v = k * p m Adjust the airflow rate by rotating the control spindle until the desired setting is achieved. Replace the tubes and spindle in the plenum. Airflow adjustment It is not possible to adjust the airflow in TSA itself. In order to enable airflow adjustment and measurement of airflow rate it is recommended that you connect the diffuser TSA 250, 315 and 400 to the TRI balancing plenum. The supply flow rate is determined by using the measurement and adjustment module MSM. TSA - Swirl Diffuser 191

With isothermal air, the throw pattern can be calculated for other terminal velocity by using correction factor : L0.3 = L0.2 x 0.67 L0.4 = L0.2 x 0.5 With non-isothermal air, the throw pattern changes due to air density. Please refer to next page or to the Halton HIT. CD-rom calculation program.
