Description
• PremiAir is a four-way induction unit for supply air, cooling or optionally, cooling and heating.
• PremiAir is designed for flush mounting in suspended ceilings and fits standard 600 mm suspended ceiling frameworks, with additional adaptation possibilities to fit most suspended ceiling systems on the market.
• The supply air flow is distributed through supply air nozzles in four directions.
• With the supply air flow as a driving force, room air is induced through the finned coil, which then removes or, where applicable, adds heat.
• Supply and conditioned return air are distributed in the room horizontally along the suspended ceiling.
• The unit has four separate adjustable nozzle strips, one in each direction. Each nozzle strip is adjustable in three positions, giving a total of 9 possible airflow settings. The nozzles can be easily be adjusted with an Allen key.
• The product is equipped with Airflex, adjustable air deflectors. Each deflector can be individually adjusted which makes it possible to achieve a draught-free indoor climate.
• The front grille of the unit is easily folded down 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.
• Heating and cooling water pipes are installed by a plumbing contractor.
• The product dimensions are adapted for flush installation in standard suspended ceiling structures.
• The unit is supplied with 4 factory-fitted suspension brackets for pendants (one in each corner). Fittings with pendants can be adjusted separately in four directions.
• 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.
• PremiAir can be ordered preset for a certain airflow from the factory.
• The device housing has four separately adjustable nozzle strips, 1 strip per side. Adjustment is quick with a 5 mm Allen key.
• Each nozzle strip is individually adjustable in three steps with corresponding air flows:
1 = Low flow
2 = Medium flow
3 = High flow
• Commissioning is primarily recommended by simply adjusting the product's nozzles with an Allen key. This way, the operating pressure is used all the way to the nozzles and sound generation is minimized.
• Commissioning can also be done by installing a commissioning damper in the duct before the beam, e.g. ZMC or DUO can be used, but not an iris-type dampers.
• 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.
