• For more information about standard materials and colors, see the separate document Product specification which can be downloaded from our website.

• The following information is only a general overview of the of assembly, installation and adjustment procedure. Always refer to the product's operation and maintenence documention (DU-SE/DV-DK) for detailed installation instructions.

• The unit is mounted in the specified number of suspension points based on the current product length, see the dimensional drawing in the product's operation and maintenence documentation (DU/DV).

• The product is connected to a circular supply air duct. Connection to a straight mounted flexible duct is not recommended.

• Heating and cooling water pipes are installed by a plumbing contractor.

• Ensure that no damage occurs to the cooling/heating coil when tightening valves and connections. To avoid this, always use a suitable wrench as counterweight.

• When installing the beam, space should be reserved for opening the front grille and accessing the device for cleaning, inspection and service.

• The product has fixed nozzles and is delivered for specific air flow at a certain nozzle pressure according to customer requiement (specified at order placement).

• It is possible to have a certain number of nozzles plugged on delivery in order to increase airflow later if necessary.

• The supply air flow is checked by measuring the operating pressure in any nozzle across the nozzle strips. When the prescribed operating pressure has been measured, the specified air flow has been achieved.

• In order to adjust the operating pressure, the product should be preceded by an comissioning damper mounted in the duct before the  unit, e.g. ZMC, but not an iris-type damper.

• When installing the commissioning damper, requirements for the preceding straight section should be taken into account, see the specific damper's documentation for detailed information.

• For calculation of K factors, see tables and calculation formula in the operation and maintenance document (DU/DV) of the beam. For K factors with a commissioning damper, please refer to the documentation of the specific damper to be used.

• When the unit is supplied with control options, the product is delivered internally pre-wired from the factory. See separate documentation depending on the current option regarding wiring, commissioning and operation of control and powering components.
