Transport and Handling of Components

Air-handling units are transported to the installation site 

either as transport-installation blocks or disassembled (for 

transport and handling of disassembled units, refer to the 

separate manual). 

Loading, unloading and handling can be performed by a 

fork-lift truck, a manipulating carriage or a crane. If lifted 

by crane, spacer bars must be inserted between the lifting 

wires to protect the air-handling unit from being damaged. 

If air-handling unit blocks without a base frame are han-

dled, fork-lift truck forks of a sufficient length must be 

used to overreach the full depth of the lifted block. If the 

air-handling unit block with a base frame is handled, forks 

of a sufficient length must be used to overreach both side 

beams of the base frame.

Figure 2 – 

Handling options

The "Other Danger" warning label situated on the face 

side of the service door indicates the hazard of catching 

by movable parts.
The service panels covering electrical equipment are 

labelled with a "Warning – Danger of Electric Shock"  

warning label.

Information and safety labels

AeroMaster CIRRUS air-handling units, respectively indi-

vidual sections, are also labelled with information labels 

indicating equipment operation, wiring diagrams, energy 

media inlets and outlets and logos of the manufacturer.

Delivery Contents

The following items are enclosed with every delivery of 

the air-handling unit:

  Accompanying technical documentation  

  (Installation and Operating Instructions)

  Commercial and technical documentation, including 

  air-handling unit assembly drawing

  Connecting material kit

  Installation kit

  Measuring & control components, respectively 

  accessories in accordance with the bill of delivery

Transport and Storage

   Air-handling units with a base frame of standard height 

(85mm) are dispatched on a pallet or transportation 

prisms. 

   Air-handling units equipped with a raised base frame 

(with supporting legs) are dispatched without additional 

handling means.

Packaging

As standard, the transport blocks of the Cirrus air-handling 

units  are packed in PE foil and provided with cardboard 

and polystyrene protecting guards. The holes in the base 

frame can be used to lift the unit by a crane.

Handling holes in base frame

Each built-in assembly is marked with a type (name) 

plate situated on the service panel side. The name plate 

includes the technical parameters of the given built-in as-

sembly. The user must ensure that every marking on the 

unit components will be readable and intact for the whole 

service life of the unit. If damaged, especially if safety is 

concerned, the marking must be repaired immediately.
