2.1.1 Type of packaging

                          Fig. 1: Type of delivery (example)
                          The device is delivered divided into several transport sections or a
                          single piece depending on the size. (Fig. 1). The transport sections
                          are individually screwed to the base frame or delivered on wooden
                          pallets and wrapped in film. The wrapping protects the device from
                          marking during transport, corrosion and other damage. Therefore,
                          do not destroy the packaging and remove only shortly before
                          installation.

                                          the unit drawing (Fig. 2). The transport section in the package is
                                          indicated in the unit drawing with an “X”. In order to connect the
                                          device with the correct terminals for installation, they are labelled in
                                          the unit drawing marked as (Fig. 2/1+2+3). The unit drawing is
                                          fixed to the outside of the transport section and is supplied as a
                                          separate document with the operating manual.

2.1.2 Symbols on the packaging
                                          The following symbols are visible on the packaging and instruc-
                                          tions must be followed during the transportation of the unit sec-
                                          tions.

                                          The symbol (Fig. 3) denotes the lifting points of the transport sec-
                                          tion for inserting the forks of the fork-lift truck and for inserting the
                                          lifting pipes to the transport section. If the unit section is marked
                                          with this symbol, then only the lifting points marked with this
                                          symbol may be used for transport (Ä 2.2.2 ‘Transport by means of
                                          fork-lift trucks’ on page 19).

Lifting points for lifting pipes
                                          The symbol (Fig. 4) denotes the lifting points for the insertion of the
                                          lifting pipes. If the unit section is marked with this symbol, then only
                                          the lifting points marked with this symbol may be used for the
                                          insertion of the lifting pipes. The transport must be fastened to the
                                          lifting pipes (Ä 2.2.3 ‘Transport with the crane’ on page 21).

Attaching tension belts
                                          The symbol (Fig. 5) marks the points at which tension belts may be
                                          placed on the transport sections while packaged. The attachment
                                          points must be used for securing and fixing the transport units to
                                          the transport vehicle.
                                          Tension straps can be easily damaged by sharp-edged loads. Use
                                          edge protection for this reason. The load is protected and the
                                          forces acting on the belt are transferred in a better manner.

2.5 Additional division of transport sections
                                             The device can be supplied as one transport section or in several
                                             transport sections. For moving the unit into the installation location,
                                             it may be possible to split the unit into sections for reassembly. In
                                             order to divide the unit into transport sections, the connections on
                                             the profile frame must be undone on each transport section. The
                                             electrical cables are contained within the different transport sec-
                                             tions. The optional refrigeration couplings for a refrigeration system
                                             are also separate.
                                             The division of the transport sections depends on the device
                                             series. The procedure for separating the profile frames and special
                                             features for the different device divisions are described below.
