Description
• CornerAir is a low-profile 1-way induction unit for supply air, cooling and heating.
• The unit is designed for installation in a wall-ceiling corner or against a wall
• Supply air and return air are distributed in the room horizontally along the suspended ceiling.
• With the supply air flow as the driving pressure, room air is induced through the finned coil, which removes or, where applicable, adds heat.
• The unit features fixed nozzles and is delivered in standard capacity steps, or based on the dimensioned flow and pressure requirements for each individual project.
•The product is also equipped with Airflex, adjustable air deflectors. The deflectors makes it possible to achieve a draught-free indoor climate.
• The front of the chilled beam is made of perforated sheet metal can easily be detached for inspection and maintenance.
Material options and finishes
• Powder coated finish.

• 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 product is connected to a circular supply air duct. Connection to a straight mounted flexible duct is not recommended.
• CornerAir has an internal duct connection with a supplied bend for alternative connection from above or from an adjacent room. The duct connection is secured with a screw.
• Heating and cooling water pipes are installed by a plumbing contractor.
• The unit is mounted in the specified number of suspension points based on the current product type and/or length, see the dimensional drawing in the product's operation and maintenence documentation (DU/DV).
• The product can be suspended using a threaded rod or mounted directly against the ceiling.
• 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.
• In order to be able to adjust the operating pressure, the product should be preceded by an comissioning damper mounted in the duct before the unit, e.g. ZMC or SPD, 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.
• The supply air flow, q (l/s or m3/h) is checked by measuring the operating pressure P (Pa) in any nozzle over the nozzle strips or over the measuring rail of the commissioning damper. When the prescribed operating pressure has been measured, the required air flow has been achieved.
• 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.
