Installation – Commissioning – Maintenance

Accessories

Connecting duct:

DIRT 4. Rectangular connecting duct with circular spigot fitted with rubber seal ring. The connection duct is tele­ scopic, 300 mm high.

Installation

Install the backing box and the connecting duct before you install the wall board. Secure the backing box to the wall studs with screws through the sides of the backing box. See the dimension table for the dimensions of the opening for the inlet spigot of the connecting duct. Cut the opening in the wall board according to the dimen­ sions specified in the dimension sketch. Install the wall board, then insert the mounting frame into the backing box and fix it in position with screws. Lastly hang the air diffuser face over the mounting frame. See Figure 1.

Commissioning

The measurement tapping is positioned at the bottom edge of the air diffuser. The K­factor (COP) is specified on the product’s identification label. K­factors (COP) can also be found in the relevant commissioning instructions avail­ able at www.swegon.com and at the end of this docu­ ment. We recommend that you use a type CRM measure­ ment and commissioning damper in the connecting duct upstream of the air diffuser’s inlet spigot for adjusting the airflow. See Figure 2.

To regulate how the air is supplied to the room, turn the air diffuser’s Varizon ® discs for air discharge in the desired direction. A straight air discharge can be achieved by taking the disc out of the diffuser, turning it 180° and reinserting it back into place. See Figure 3.

Maintenance

The air diffuser can be cleaned, if necessary, using luke­ warm water with dishwashing detergent added or by vacuum cleaning using a brush nozzle. The duct system can be accessed by removing the diffuser face and the air distribution panel.
