Function and use I Models FUNCTION AND USE The ceiling slot diffuser type DSC-PLASTER is suitable for use in rooms from 2.6 m to 4 m high for direct installation in plasterboard ceilings or ceiling cavities (pressure ceilings). The special shape of the frame profile allows good installation in the plaster board ceiling. Filling in Q3 quality is possible up to the air outlet slot. Frame profiles are fitted with bores to allow them to be connected to the plasterboard ceiling using screws. The clamp strap fastening allows easy mounting in the plasterboard ceiling. The air deflection blades adjustable from below allow a variety of throw adjustment options. In cooling mode, a one- or two-way air throw pattern can be set. This achieves high induction while the velocity and temperature difference of the supply air jet are effectively reduced.

Pressure loss and sound power level remain therefore constant even when the blades are adjusted. A subsequent change of the air throw pattern on site is possible at any time. If a desired blade position is specified in the order, it will be set at the factory. The large free cross-section allows a greater volumetric flow compared with other slot diffusers. The stable air jet and high induction means that the DSC-PLASTER slot diffuser can be used in cooling mode up to ΔT 0-8 K. The resistance created by the blades ensures that the supply air is distributed equally across the whole length of the slot diffuser. The ceiling slot diffuser can be manufactured as 1- or 2-slot model and is available either as single piece or in band design.

Mounting instructions The clamp straps are delivered loose. Introduce the screw through the bore into the inner blade mount and screw it down with the clamp strap. Position the clamp straps in longitudinal direction and introduce them into the ceiling together with slot diffuser (see installation position). Then rotate the clamp strap by about 90 by rotating the screw and lower it over the slot diffuser profile (see clamping position). Tighten the screw until the slot diffuser is firmly locked at the ceiling. No return possible Version: 2018-09-06 Page 7
