COMPOSITION AND METHOD OF OPERATION conduit

Structure The DRS air diffuser is composed of a front plate (1) with blades that are integrated into the exit of the diffuser (2).The diffuser is held up by a concealed central screw (3).

raccord adapté (spigot)

Operation The blades divide the airflow into numerous single high-induction airflows. The blades integrated into the exit of the diffuser ensure a horizontal air flow even at a slow rate, while cooling up to a minimum of 25% in variable air volume (VAV).

MAINTENANCE LThe diffuser DRS of NAD Klima requires no special maintenance other than periodic cleaning. We recommend cleaning the diffuser with a multi-filament brush or duster microfiber that you will pass softly on the diffuser. Thermolacquered finish for easy cleaning of the diffuser as dust does not stick to it.

INSTALLATION IN A CEILING GYPSUM DRS-Q A) Opening in the gypsum Choose one of the three (3) options instalation shown at right. Option 1 et 2 Calculate the dimensions of the diffuser - Add 13 mm (1/2 ") in width and 13 mm (1/2 ") in length - Cut the square in the gypsum corresponding to these measures (Diffuser size + 13 mm) - Around this hole, insert a plaster frame and fix it NOTE : Make sure the final square hole is 13 mm (1/2 ") wider than the diffuser. Option 3 Calculate the dimensions of the diffuser - Remove 13 mm (1/2”) - Cut the square in the gypsum corresponding to these measures (Diffuser size - 13 mm) - Around this hole, insert a plaster frame and fix it NOTE : Make sure the final square hole is 13 mm (1/2 ") smaller than the diffuser. B) Install the plenum The plenum will be suspended through four (4) suspension holes provided for this purpose and use a metal wire. As indicated in the drawing to the right, install the plenum by adjusting its height ; according to option 1 and 2, the base of the plenum must enter 1/8 " in the hole or, option 3, the base plenum will press the drywall outside the hole

INSTALLATION IN A CEILING GYPSUM DRS-R Option 1

A) Opening in the gypsum Choose one of the two (2) options      instalation shown at right. Option 1 - Measure the diameter ( ØD ) of the diffuser - ADD 1/2 inch or (13 mm) - Cut a circle in the gypsum equivalent to this new measure [ ØD+1/2 inch (13 mm)] - Around this hole, place the gypsum guide and fix it. Note : Make sure that the final diameter of the hole is well from 6.5 to 10 mm (1/4 "to 3/8") wider than the diameter of the diffuser. Option 2 - Measure the diameter (ØD) of the diffuser - REMOVE 1/2 inch or (13 mm) - Cut a circle in the gypsum equivalent to this new measure [ØD-1/2 inch (13 mm)] - Around this hole, place the gypsum guide and fix it. Note : Make sure that the final diameter of the hole is well 13 mm to 19 mm (1/2 "to 3/4") smaller that the diameter of the diffuser.
