Ceiling installation of units – General instructions

The RLT Flat air handling units are supplied as monoblock units in one piece (no assembly required).

• Observe transport dimensions (doors and passages must have sufficiently large openings)!
• The load-bearing capacity of the ceiling, installation construction, dowels and screws must be designed for the weight of the unit, e.g. use heavy-duty dowels. Mounting material is to be provided by the customer.
• When installing the unit, level it (applies to the version with a sensitive heat exchanger so that the condensate can be properly drained via the condensate drip tray installed in the base of the unit and the condensate drain).
• The unit must be freely accessible for servicing/maintenance.
• Ceiling constructions (e.g. a suspended ceiling) must not touch the unit. If this is not the case, vibrations could be transferred, resulting in increased sound radiation.
• Provide adequate space (approx. 50 cm) under the unit for maintenance work. Measure the mounting holes on the top. Using the measurements recorded, produce your mounting points under the ceiling with the mounting material provided by the customer.
• Suitable measures such as structure-borne sound decoupling elements for M10 threaded rods must be provided for structure-borne sound decoupling.
• Ensure free access to all components (control devices, fans, filters, etc.) for maintenance purposes and to guarantee the possible replacement of faulty parts. Great care has been taken to ensure the tightness of the unit. Ensure that the rectangular duct network is also airtight, especially at the connection points with the unit.
• Care must be taken to ensure that the maintenance and service doors can be opened at a convenient distance during installation of the system, taking into account possible failure of the fan and replacement of the heat exchanger.
