Mounting The air curtain is installed horizontally with the supply air grille facing downwards as close to the door as possible, concealed in the false ceiling. The only visible part of the unit is the underside which is level with the ceiling. The service hatch must be accessible, nothing should prevent it being fully opened. The unit is ready for suspension with threaded rods on its outside. The threaded rods can also be fixed on the inside of the unit e.g. when mounted on a solid suspended ceiling. For the protection of wider doorways, several units can be mounted next to each other....

AR3500 Connection The PC board SIRe is built into the air curtain on delivery and is equipped with modular connectors for easy connection of external components. Read more about the SIRe control system in the "Controls" section. Unit without heating Connected via the built-in control board with 2 m cord and plug. Unit with electrical heating The electrical connection is made on the side of the unit. Control (230V~) and power supply for heat (400V3~) should be connected to a terminal block in the terminal box. For units with electrical heating, power and control should be supplied...
