7 ACOUSTIC DATA The diagrams provide a summary of the A-weighted sound power level from air-extract unit, L WA. Correction factors in table 8, page, are used to calculate emitted sound power level at the respective frequencies, L W = L WA + KO. A room with absorption equivalent to m² Sabine will have a sound pressure level which is 4 db below the sound power level emitted. Example: A room requires an indoor air extraction level of 80 l/s, and for this purpose a UPK-R 0x0 and ATK with rear-entry spigot is used. Room attenuation is 4 db, and the damper is to be chocked 20 Pa. According to diagram 4, L WA = 32 db(a) with open damper and 21 Pa total pressure loss. We aim to find: a) Emitted sound power level from air-extract unit at 2 Hz, damper open. b) A-weighted sound pressure level in the room with damper open. c) A-weighted sound pressure level in the room with damper chocked. d) Emitted sound power level from air-extract unit at 2 Hz, damper chocked. Solution: a) According to table 8, the correction factor for 2 Hz is -2 db. L W at 2 Hz is thus: L WA + KO = 33 + (-2) = 31 db b) A room attenuation equivalent to 4 db provides a sound pressure level in the room of: 31-4 = 27 db(a) c) 20 Pa chocking produces 41 Pa, and the diagram shows an increase in L WA of 3dB. The sound pressure level is thus: = db(a) d) According to table 8, the correction factor for 2 Hz is -6 with damper closed and -2 with damper open. The factor to be used for our working point position is thus +3. Emitted sound power level L W at 2 Hz is then: L WA + KO = 33 + (-3) = db(a) DIMENSJONERINGSDIAGRAM Diagram 1, UPK-R w / ATK-B 200x0 Ø125 Diagram 2, UPK-R w / ATK -S 200x0 Ø

17 INSTALLATION ATK box and mounting frame are assembled as shown in fig., and the air-extract grille is then positioned in the mounting frame. Installation principle for ATK-H is illustrated in fig. 11. COMMISSIONING During commissioning, the unit front must be fitted. The adjustment wire is pulled out through the front. For ATK-B, S and LS, the measuring tube is pulled through the front as well. The damper is secured by using a clamping nut on the wire. For UPK BxH a separate measurement and adjusting unit for commissioning is recommended. MAINTENANCE The unit should be cleaned by using a damp cloth. When cleaning the duct network, the diffuser front must be removed in order to gain access to the duct. In a plenum box is used, the damper must be removed in order to gain free access to the duct.
