    Transport and Storage DANGER Do not stand under/near suspended loads while transporting air handling unit modules. ATTENTION The unit must never be lifted, pulled or pushed using any protruding parts other than the main frame, such as coils, dampers. ATTENTION The unit must not be tilted during transport or lifting.
  • Page 7 ATTENTION If a forklift is used during transportation, make sure that the forklift blades pass through the bottom of the units. Otherwise, it may damage the panels at the bottom of the units. Forklift blades must be long enough to pass through the module completely! ATTENTION If the units are lifted with a forklift, the lifting operation should be carried out by considering the center of gravity of the module and making sure that the load is evenly distributed on the forklift forks.

    Air handling units can wait for the time of assembly at construction sites or warehouses. In such storage situations, the warnings below should be taken into account. • In order to avoid pollution, all gaps in the air handling unit must be covered. If stored in a wet environment, sufficient ventilation should be provided.

  • Page 10: Module Combination

    In order to take out the components for reasons such as cleaning, maintenance and replacement, While locating the unit, gaps of appropriate sizes should be left around the unit. This space should be on the service side of the unit and at least 1.2 times the width of the unit.
  • Page 11 ATTENTION The pedestal under the modules must be used to bring the modules close enough to each other! Fix a suitable tensioning strap to the pedestal and tighten the tensioning strap for this task. Make sure the modules get close enough with the base. ATTENTION Assembling with the tensioning strap should be done using only pedestal.

  • Page 20: Control Panel And Bms Connections

    CAUTION Documents containing electrical and automation details of the air handling unit are attached to the automation panel or the module with the accessories. All electrical connections must be made according to this document. 3.12.1.1 Control Panel and BMS Connection Air handling units that are requested with automation equipment can be integrated with the building automation system via Modbus TCP-IP / Bacnet protocols and can be monitored with these protocols.

  • Page 21: Panel Mounting

    Depending on the project variation, the air handling unit may have different component selections. In units where there is no automation panel, electrical connections have been moved to junction boxes placed outside the device. In order to reduce the starting current in motors above 4kW, “star-delta” motor connection is made. 3.12.2.1 Panel Assembly In air handling units ordered with automation, the panel may not be mounted on the device by special request.
