ner of the units. Sample label is above.
Lifting and Transport
An instruction is attached to the AHU describing the
procedures that must be followed for lifting and trans-
port. For further details on this subject, see Chapter
2.
Packing materials must be disposed of in a respon-
sible manner end in accordance with local regula-
tions.
2. TRANSPORT & LIFTING IN-
STRUCTIONS
2.1. General
Transport and lifting of 39HQ AHUs must always be
in accordance with the instructions below. If these in-
structions are not observed, irreparable damage may
occur to the unit, and people in the immediate vicinity
of the unit are also endangered. Alarko Carrier San-
ayi ve Ticaret AS does not accept any responsibility if
these instructions are not observed.
personnel. The AHU must only be lifted with lifting
bars supplied by Alarko Carrier Sanayi ve Ticaret AS.
Lifting must be carried out in accordance with local
2.2. Transport & Storage
Lifting of the AHU is only permitted under the des-
ignated lifting methods. For transporting marked
points shall be used. If it is not possible to use
marked points due to the loading conditions, trans-
porting can only be done by forklift (cranes can-

Take appropriate precautions on site and do not
move the protection cover unless you complete the
installation of the unit.
2.3. Roof edge protection during trans-
port (outside installation)
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 dis-
tortion by the tie ropes protection plates are added.
Fig. 1. Before lifting, place support proler as shown
in Fig. 1.
2.4. Ooading or 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 cell sections, al-
ways consult the documents that give the dimensions
and weights of the sections, as well as the installation
sequence. For ease of installation, follow dimension-
al drawings indicating cell dimensions and weight.
The weight of each transport section is given on the
unit (See Appendix -1). The points that will be used
for transport are marked by the label shown below on
base frame.
For lifting and moving AHUs, the following methods
are recommended:
Method 1
Attach hoisting ropes to lifting bars. Evenly positioned
be used between the lifting ropes to prevent dam-
age to the top of the unit and ensure that no excess
pressure is applied to the side panels. Spacers used
should be durable to the force applied by the ropes
(in terms of dimension and material).
Fig. 2. Vertical transport using pallet truck
Method 2
Attach hoisting ropes connected to lifting bars to lift-
ing beams. To do this (in terms of strength), use a
proper beam.
Note: For lifting, make sure load is distributed evenly.

2.5. Horizontal Transport
For horizontal transport, pallet lifters or transport
skids can be placed under unit frame or under the
lifting bars. Lifters used should be placed properly to
support the lifting points. During lifting and transport
process, never use transversal side base frame pro-

culation.
Determine correct assembly sequence of AHU sec-
tions. Use the most logical sequence, taking the in-
stallation site into account.
Each cell composing AHU has a label showing order
number, module number and its weight, and a num-
ber system indicating adjacent modules is applied.
Connect the modules considering these labels (See
Appendix -1).

4. Position the lifting ropes on lifting bars. Evenly posi-
should be used between the lifting ropes to prevent
damage to the top of the unit and ensure that no ex-
cess pressure is applied to the side panels. Spacers
used should be durable to the force applied by the
ropes (in terms of dimension and material).

5. Before proceeding lifting, make sure load is dis-
tributed evenly and check if the steps above are per-
formed (Lifting bars cannot be removed if there is no
enough space between the unit and the wall)
As shown in the example below, it is not possible to
remove 6th section of the AHU from the right side
because it is so close to the wall. Bar can be re-
moved from the left side if 3rd section of the AHU is
not placed. When 6th section is placed, remove bolts
and plates on the right side to remove the lifting bars.

The labels showing the matching surfaces are for
easily matching the unit surfaces correctly during as-
sembly of AHU. Same numbers should be side by
side.
Note: Attach the insulation tape supplied to only one
of the two assembled sections.
Ensure that both sections can still be moved. In-
sert a lifting bar into both sections, so that they
can be pulled closer towards each other.
Two methods can be used for pulling the sections to-
wards each other:
Method 1
Pull the sections against each other, using the pull
ropes attached to the lifting bars. Pull evenly on both
sides of the AHU.

Method 2
Insert a bar with threaded ends through both lifting
bar holes. Screw a nut onto the threaded ends of the
bar and tighten it. Pull evenly on both sides of the
AHU.
Note: Before connecting the sections, they should be
horizontally and vertically aligned.
5.2. Connection of Modules having
Equal Width and Height
To connect the AHU sections, use one of the follow-
ing methods according to AHU construction.

a bolt. After assembly, both sections must be fully
aligned.
Section joining shall be made from internally when-
ever possible, if it is not possible it will be made from
externally. Outside joining shall not be chosen, if join-
ing from internally is possible.
Section joining shall be made with parts shown on
Figure 17. Distance between the parts shall be equal
as shown on Figure 18-19. See Annex-4 for quanti-
