Accessories
Commissioning box:
ALS. Made of galvanised sheet steel. Contains removable commissioning damper, fixed measurement tapping and sound absorbing insulation with reinforced surface layer. Fire resistance rated to
B-s1,d0 in accordance with EN ISO 11925-2.
Frame:
SAR C. For aesthetic installation of a lowered diffuser.
Blanking-off a sector of the diffuser face:
SAV. For blanking off a sector of the air distribution pattern.
Installation
The diffuser inlet sleeve should be secured to the connecting duct with blind rivets. The diffuser face can be removed by turning the springs that hold the diffuser face’s "pins" one quarter of a turn
(see Figure 2). If an ALS commissioning box is used, the sleeve coupling between the ALS and the air diffuser can be lengthened using an ordinary circular duct of up to 500 mm without having to lengthen the measuring tubes and damper adjustment cords. See
Figure 2.
Commissioning
Commissioning must be carried out with the diffuser face mounted. Pull the measuring tubes and damper adjustment cords out through the air diffuser slot. Then connect the manometer to the correct measuring tube. The red tube in the ALS commissioning box is used for supply air. The rated coefficient of performance of the air register can be used in a calculation to determine the required commissioning pressure. Conclude commissioning by adjusting the damper to the correct blade position, tie a commissioning knot in the damper cords to indicate the damper position.
See Figure 1.
Measurement accuracy and requirement on straight duct before the commisioning box, see Figure 2. The requirements of straigh duct depends on the type of disturbance before the commissioning box. Figure 2 shows a bend, a dimensional change and a
T-piece. Other types of disturbances requires at least 2xD straight
(D = connection dimension) for measurement accuracy of ± 10% of the flow.
The rated coefficient of performance (K-factor) is specified on the identification label of the product and in the relevant commissioning instructions at www.swegon.com.
Maintenance
The air diffuser can be cleaned, if necessary, using lukewarm water with dishwashing detergent added or by vacuum cleaning using a brush nozzle.
The duct system can be accessed for cleaning by removing the diffuser face. Do so by turning the springs that hold the diffuser face’s "pins" one quarter of a turn. If a type ALS commissioning box is used, swing the distribution plate to the side on so that you then can grip the handle of the tubular damper casing and rotate it out of its holder. See Figure 2.
