1 - TRANSPORT AND LIFTING INSTRUCTIONS
1.1 - GENERAL
Transport and lifting of the HHFlex air handling units
(AHU) must always be in accordance with the instruc-
tions below. If these instructions are not observed,
irreparable damage may occur to the unit, and people in
the immediate vicinity of the unit are also endangered.
Systemair B.V. accepts no liability whatsoever for work
carried out by third parties.
Transport and lifting must be carried out by qualified
personnel. The AHU must only be lifted with lifting bars
supplied by Systemair B.V. Lifting must be carried out
in accordance with local regulations and with the help
of certified lifting aids.
1.2 - Transport and storage
Lifting of the AHU is only permitted at the desig-nated
lifting points. Lifting under the cross beams is prohibited.
This applies to transport as well as storage, and is
indicated on the cross beam with the following label.

(outside installation)

Roof edge transport protection
During transport by truck the units are attached to the
loading surface with tie ropes, pulled across the unit
towards the side edges of the truck.
On external units, to protect the roof edge from
distortion by the tie ropes, protection pieces are added.
1.4 - Offloading and hoisting
Depending on the dimensions of the AHU and the
situation on site, the AHUs are supplied in previously
agreed transport sections. Before proceeding with the
transport and installation of the casing sections, always
consult the applicable dimensional drawings that give
the dimensions and weights of the sections, as well as
the installation sequence.
The weight is given on each transport section. Each
transport section is equipped with a subframe with six
lifting points. These points are marked by the label
shown below.

To unload or hoist the AHU, the following methods are
recommended:
Method 1
• Attach the lifting cables to the lifting bars. Evenly
positioned spacer bars should be used between the
lifting cables to prevent damage to the top of the
unit and ensure that no excess pressure is applied
to the side panels.

Method 2
•
Attach the lifting cables that are on the lifting
beam to the lifting bars. To do so, use an approved
lifting beam.
