1 - TRANSPORT AND LIFTING INSTRUCTIONS
1.1 - GENERAL
Transport and lifting of the 39HQ air handling units (AHU)
must always be in accordance with the instructions 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. Carrier Holland Heating accepts no
liability whatsoever for work carried out by third parties.
Transport and lifting must be carried out by qualied personnel.
The AHU must only be lifted with lifting bars supplied by Carrier
Holland Heating. Lifting must be carried out in accordance
with local regulations and with the help of certied lifting aids.
1.2 - Transport and storage
Lifting of the AHU is only permitted under the designated
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.
Fig. 1 - Lifting not allowed
1.3 - Roof edge protection during transport (outside
installation)
Fig. 2 - Roof edge protection
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.
Fig. 3 - Lifting point
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.
Fig. 4 - Vertical transport using spacer bars
Method 2
• Attach the lifting cables that are on the lifting beam to the
lifting bars. To do so, use an approved lifting beam.

Fig. 5 - Vertical transport using a lifting beam
NOTE: For hoisting please ensure that the weight is evenly
distributed.
1.5 - Horizontal transport
For horizontal movement pallet lifters or transport skids can be
placed under the installation frame or under the lifting bars. It is
important that these support the lifting points. At no time should
the cross beams at the ends of the unit sections be used for jack-
ing or tracking the AHU. FOR HORIZONTAL TRANSPORT
ALWAYS PROVIDE SUPPORT UNDER THE LIFTING
POINTS. The use of pipes as rollers can result in damage to the
installation frame.
Fig. 6 - Horizontal transport using rollers
2 - PREPARATION FOR ASSEMBLY
The following material is supplied as standard by Carrier
Holland Heating:
• Installation, maintenance and operating instructions
• Lifting instructions
• II A declaration
• Kit
• Connecting bolts/screws
• Connecting strips/screws
• Lifting bars
The following material is supplied as an option by Carrier
Holland Heating:
• Siphon
• Anti-vibration mats
• Outside air suction grille
• Heat recovery wheel control
• Steam generator plus accessories
• Minihelic and Allen key instructions
• Door key
Check that all necessary parts are supplied with the AHU.
Measure the location and make sure it is tidy. The oor of the
installation area should be level and at to avoid connection
problems. Any uneven surfaces should be evened out with inll
plates.
Determine the correct assembly sequence of the AHU sections.
Use the most logical sequence, taking the location into account.
Begin with the casing section that must be positioned on the
highest part of the oor, so that the other casing sections can be
added around it.
3. LIFTING INSTRUCTIONS
3.1 - General
There are transport and lifting instructions attached to the AHU.
3.2 - Lifting bar certification
The lifting bars supplied are for single use and certied in
accordance with Machinery Directive 98/37/EC, annex II-A.
Selection, checking and testing of the lifting bars is supervised
by a qualied person in accordance with the EKH (“Erkende
Keurbedrijven Hijs- en Hefmiddelen”) work instructions.
Registration mark and number:
• LCH1 + 1A
• LCH2 + 2A
3.3 - Fastening of the lifting bars
• Remove the bolt and the locking plate on one side of the
lifting pipe.
Fig. 7 - Fastening the lifting bars - 1
• Slide the lifting bar into the hole in the subframe intended
for that purpose.

5
Fig. 8 - Fastening the lifting bars - 2
• After inserting the lifting bar, re-insert the bolt and locking
plate in the correct position.
Fig. 9 - Fastening the lifting bars - 3
• Position the lifting cables on the lifting bars (4 or 6 off).
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.
Fig. 10 - Vertical transport using spacer bars
• For hoisting ensure that the weight is evenly distributed
and that all previous steps are carried out correctly.
If there is not enough space it may not be possible to remove
the lifting bars. In the example below, the lifting bars cannot be
removed on the right-hand side of the 6th AHU section, as the
wall is too close and the lifting bars are too long. It would be
possible to remove them from the left-hand side, if the third
AHU section has not yet been placed. Ensure that the bolt and
the locking plate are removed from the right-hand side of the
lifting bar, when the 6th AHU section has been positioned.
Fig. 11 - Location diagram
4 - ASSEMBLY
4.1 - AHU assembly
• Place the anti-vibration mats where the rst casing section
will be positioned.
• Place the rst casing section on the anti-vibration mats,
and then remove the lifting bars.
Fig. 12 - Anti-vibration mats
• Then place the anti-vibration mats where the next casing
section will be positioned and then place this section.
• Before placing the sections against each other, x the
sealing tape supplied between the sections. This should be
done in four places, and the sealing tape should overlap at
the corners. See Figs. 17 and 21.
NOTE: Attach the sealing tape supplied to only one of the two
assembled sections.
• Place the sections as close together as possible. Ensure that
both sections can still be moved. Insert a lifting bar into
both sections, so that they can be pulled closer towards
each other.
There are two methods for pulling the sections towards each
other:
Wall
Lifting bar

6
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.
Fig. 13 - Linking the casing sections with pull ropes
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.
Tighten it evenly on both sides of the AHU.
Fig. 14 - Linking the casing section with a bar
NOTE: Before connecting the sections, they should be horizon-
tally and vertically aligned, using inll plates. If the oor is
not completely level, rst place the casing section that will be
on the highest part of the oor.
4.2 - Connecting casings of equal width and height
Fig. 15 - Unit of equal width and length
To connect the AHU sections use one of the following methods.
The method depends on the AHU construction.
Method 1
This method applies for sections that end in joint mullions:
• Check that the four corners are attached.
Fig. 16 - Joint mullions with linking corner pieces
• Ensure that the sealing tape supplied is xed to one of the
two sections, before moving the sections against each other.
Fig. 17 - Fixing the sealing tape to the joint mullions
• Use the pre-mounted corners for the nal positioning of
the sections and secure the corners with a bolt. The
sections must be fully aligned.

Fig. 18 - Corner connection
• Remove the rst two corners and mount the aluminium
connection strip to the base. Remove the next two corners
and mount the connection strip against the side wall. Repeat
this for the other AHU corners.
Fig. 19 - Fixing the connection strip
Method 2
This method applies for sections that end with corner posts.
Fig. 20 - Corner posts with coupling profile
• Ensure that the sealing tape supplied is xed to one of the
two sections, before moving the sections against each other.
Fig. 21 - Fixing sealing tape to the corner posts
• Link the sections by connecting the pre-mounted corner
posts with bolts and nuts (M6).
Fig. 22 - Connecting the corner posts
• If there are more than two sections, repeat the procedure
above. For an outdoor installation all external joints
should be sealed.
For an outdoor installation the plastic roof cover must be
nished as described in chapter 7.
NOTE: If the AHU needs to comply with air tightness class
L1 (LuKa C), the internal connection strip joints and/or
proles should also be sealed.
4.3 - Connecting casings of differing height
Fig. 23 - Unit of differing height
After the internal connection of the sections an indoor installa-
tion requires no further nish (see chapter 4.2). For the external
nish of an outdoor installation use one of the following methods:

8
Method 1
• Check if the cover strip has been applied at the correct
height on the projecting section.
• Fix the plastic nish layer to cover strip above with the
screws provided.
• Add a second cover strip over these screws.
• Position the sections against each other so that the corner
posts of both casings are touching and rst connect the
sections internally, as described in chapter 4.2.
• Attach the projecting strip of the plastic roof foil over the
connection prole of the lower casing section with a blow
dryer.
Fig. 24 - Roof finish, units of differing height - 1
NOTE: All resulting external joints should be sealed.
Method 2
• Check that the cover strip and the protection prole are
mounted at the correct height of the projecting casing section.
• Apply the sealing tape supplied to the connection prole
of the lower casing section.
• Position the lower section with the pre-mounted connection
prole against the projecting section so that the corner
posts of both sections touch, and connect the sections rst
internally, as described in paragraph 4.2.
• Screw down the connection prole of the lower section to
the cover strip, and remove any drill shavings.

NOTE: For an outdoor installation, seal all jonts resulting
from the mounted proles. This applies to both corner and
butt joints.
5.3 - Units with different widths
For units with different widths there are four different situations.
For an indoor installation the method described below applies
to all situations.
Indoor installation
The top section icludes a projecting cross beam that is effectively
as wide as the bottom section.
• Check that the cover strip at the ends of the bottom section
is installed in the correct place.
• Position the top section as indicated in the dimensional
