1 - SAFETY CONSIDERATIONS
1.1. General
The 39HQ air handling units (AHUs) has been de-
signed and manufactured in accordance with the
CE machine directive EN292. In order to guarantee
safe operation and use of the unit, please carefully
read and observe the instructions in this document
and pay special attention to the warnings that apply
to this unit. Any modifications in the design and/or
installation of the AHU that are carried out without
discussion with Alarko Carrier and without advance
written agreement will result in the loss of the right
to any warranty claims and any claim for injury to
personnel as a result of these modifications.
Maintenance procedures may only be carried out by
qualified personnel.
Heating and cooling elements are manufactured and
supplied in accordance with guidelines of the Pres-
sure Equipment Directive (PED).
CE declaration of AHUs is given Annex-4.
1.2. Applications
The AHU is designed for the movement and con-
ditioning of air, unless otherwise agreed during the
design stage.
1.3. Instruction Types
The following warning pictograms and labels with
text are used.
Lifting Point
This label shows where the AHU can be lifted with
support beams. Support beams shall be used with
cranes. If forklifts are used for lifting, support beams
cannot be used.
Transporting From Side Base
It is forbidden to place lifting devices for transport and
storage under side profiles.
Earthing
This pictogram indicates where the AHU must be
earthed and is on one of the support beams beneath
the casing in the fan section.
- The electrical components in the AHU must be
earthed, except for components with double insula-
tion and/or components with a supply voltage below
50 V.
- The electrical components must be installed in ac-
cordance with national and local regulations.
Rotating Parts
This pictogram indicates that there are rotating parts
behind this access cover, door or panel which may
cause injury. The components that include rotating
parts are the fan and heat recovery wheel. If there
are special customer-specific components behind
doors, access covers or panels that include rotating
parts and pose a potential risk, this is also indicated
by this pictogram.
Hot Surfaces
This pictogram indicates that there are components
behind this access cover, door or panel that can
cause serious burns when touched.
The components that may have hot surfaces are
the steam humidifier, steam heater and the electric
heater. If there are special customer-specific com-
ponents behind doors, access covers or panels that
have hot surfaces and pose a potential risk, this is
also indicated by this pictogram.

6
Electrical Voltage
This pictogram indicates that
there are electrical components
behind this access cover, door
or panel that may be dangerous
for the user/installer. Only per-
sonnel qualified in accordance
with EN50110 is permitted to
carry out work on these compo-
nents. The pictogram is attached to the access cover
for the electric heater control box.
Removal of Transport Brackets
This pictogram is located at the bottom of the fan
section. It indicates that the transport brackets must
be removed during commissioning before the fan is
started up.
Central Data
This label contains the data for the AHU, such as
order number, position number etc. If present, the
label is normally located on the access cover or the
door of the fan assembly.
Opening the Fan Door
This pictogram is positioned on the outside of the door
or access cover of the fan assembly. This pictogram
warns that the fan must have been switched off and
deenergised for a minimum of two minutes before
the door or access cover is opened.
Caution: All doors and access covers must be closed
before starting up the AHU.
Unit Matching Label
This label shows that matching surfaces of AHU units
for assembly. It exists at bottom right and left corner of
units. Sample label is as follows.
Lifting and Transport
An instruction is attached to the AHU that describes
the procedures that must be followed for lifting and
transport.The following chapter contains further
details.
1.4. Disposal of Parts/Materials
- The packaging material must be disposed of in a
responsible manner and in accordance with local
regulations.
- Components that are replaced, must be disposed
of as described above.
2. TRANSPORT AND LIFTING INSTRUCTIONS
2.1. General
Transport and lifting of the AHU 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 does
not accept any responsibility if these instructions are
not observed. Transport and lifting must be carried out
by qualified personnel. The AHU must only be lifted
with lifting bars supplied by Alarko Carrier. Lifting must
be carried out in accordance with local regulations
and with the help of certified lifting aids.
2.2. Transport and Storage
Lifting of the AHU is only permitted under the desig-
nated 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 from side profiles can only be done by forklift
(cranes cannot be used). This applies to transport as
well as storage, and is indicated on the side profiles by
warning label.
Air Handling Units deliver to the side by sections. Mov-
ing the plastic cover will let the dirt and particulates en-
ter to the unit from openings. Do not move the protection
cover unless you complete the installation of the unit.

7
2.4. 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 drawing that give the dimensions and
weights of the sections, as well as the installation
sequence.
The weight is given on each transport section (See
Appendix 1). Each transport section is equipped with
a subframe with four lifting points.These points are
marked by the label shown below.
For offloading as well as hoisting lifting cables can be
attached 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.
For hoisting please ensure that the weight is evenly
distributed.
The AHU should not be lifted or moved under the
cross beams. This is indicated by the label below.
2.3. Roof edge protection during transport
(outside installation)
Roofedge 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 distor-
tion by the tie ropes protection plates are added.
For safety reasons these protection plates must be
fixed.This is done by attaching them with self-tapping
screws to the roof edge.
Make sure that the protection plates are removed after
arrival on site before the AHU is lifted.
2.5. 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 jacking or
tracking the AHU. FOR HORIZONTAL TRANSPORT
ALWAYS PROVIDE SUPPORT UNDER THE LIFT-
ING POINTS. The use of bars as rollers can result in
damage to the installation frame.

4. LIFTING INSTRUCTIONS
4.1. General
There are transport and lifting instructions attached
to the AHU.
4.2. Lifting Bar Certification
The lifting bars supplied are for single use and certi-
fied in accordance with Machinery Directive 2006/42/
EC, annex II-A. Selection.
4.3. Fastening of the Lifting Bars
• Remove the bolt and the locking plate on one side
of the lifting pipe.
Figure 5. Fastening the lifting bars - 1
• Slide the lifting bar into the hole in the subframe
intended for that purpose.
3. PREPARATION for ASSEMBLY
The following material is supplied as standard by
Alarko Carrier:
• Installation, maintenance and operating instruc-
tions
• Installation, operation and maintenance manual
• II A declaration
• Connecting parts
• Material list
The following material is supplied as an option by
Alarko Carrier:
• Anti-vibration mats
• Outside air suction grille
• Heat recovery wheel control
• Steam generator and accessories
Check that all necessary parts are supplied with the
AHU.
Measure the location and make sure it is tidy. The
floor of the installation area should be level and flat
to avoid connection problems. Any uneven surfaces
should be evened out with infill plates.
Determine the correct assembly sequence of the
AHU sections. Use the most logical sequence, tak-
ing the location into account. Begin with the casing
section that must be positioned on the highest part
of the floor, so that the other casing sections can be
added around it.

9
- For hoisting ensure that the weight is evenly dis-
tributed 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 can not 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.
Figure 9. Location Diagram
Figure 6. Fastening the lifting bars - 2
Figure 7. Fastening the lifting bars - 3
• After inserting the lifting bar, re-insert the bolt and
locking plate in the correct position.
• 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.

5. ASSEMBLY
5.1. AHU Assembly
• Place the anti-vibration mats where the first casing
section will be positioned.
• Place the first casing section on the anti-vibration
mats, and then remove the lifting bars.
Figure 10. Anti-vibration mats

10
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.
5.2. Connecting Casings of Equal Width
and Height
To connect the AHU sections use one of the follo-
wing 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.
Figure 14. Joint mullions with linking corner pla-
ces
- Ensure that the sealing tape supplied is fixed to
one of the two sections, before moving the sections
against each other.
• 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, fix
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.
The labels which show the matching surfaces are for
making easy the matching of unit surfaces correctly
during assembly of AHU. Same numbers should be
side by side.
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 to-
wards each other:
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.
Figure 11. Linking the casing sections with pull
ropes
Figure 12. Linking the casing section with a bar
NOTE: Before connecting the sections, they should be
horizontally and vertically aligned, using infill plates. If
the floor is not completely level, first place the casing
section that will be on the highest part of the floor.
Figure 13.
Unit of equal width and length

Figure 17. Fixing the connection strip
This method applies for sections that end with corner
posts.
Figure 15. Fixing the sealing tape to the joint mulli-
ons
- Use the pre-mounted corners for the final positioning
of the sections and secure the corners with a bolt.
The sections must be fully aligned.
Figure 16. Corner connection
- Remove the first two corners and mount the alumini-
um 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.
Figure 18. Corner posts with coupling profile
- Ensure that the sealing tape supplied is fixed to
one of the two sections, before moving the sections
against each other .
Figure 19. Fixing sealing tape to the corner posts
- Link the sections by connecting the pre-mounted
corner posts with bolts and nuts (M6).
Figure 20. Connecting the corner posts
- If there are more than two sections, repeat the pro-
cedure above. For an outdoor installation all external
joints should be sealed.
Method 2

6. STACKED CASING SECTIONS
For an outdoor installation the plastic roof cover must
be finished as described in chapter 8.
NOTE: If the AHU needs to comply with air tightness
class L1 (LuKa C), the internal connection strip joints
and/or profiles should also be sealed.
5.3. Connecting Casings of Different Height
Figure 21.
Unit of different height
After the internal connection of the sections an indoor
installation requires no further finish (see chapter 5.2).
For the external finish of an outdoor installation use
following method:
• Check if the cover strip has been applied at the correct
height on the projecting section.
• Fix the plastic finish 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 first connect the
sections internally, as described in chapter 5.2.
• Attach the projecting strip of the plastic roof foil over
the connection profile of the lower casing section with
a blow dryer.
Figure 22.

Indoor Installation
For indoor installation connection profiles of 240 mm
length are supplied.
• Position the casings on top of one another so that
the corner posts are in the same plane. The base
frame of the top section should be slightly back com-
pared to the bottom casing section.
If stacking units in an indoor installation the connec-
tion profiles should be placed between the different
unit sections. Use the following assembly method:
• Install a connection profile to the end of the casing
section, stopping at the module line (A).
• Install a connection profile at the joint (B).
•Install a connection profile against the adjacent
section (C).
(Equal Width)

diate base frame
Figure 30-2. Fixing profile, indoor location with inter-
mediate base frame
There is no need for a connection profile at the ends
of the unit.
NOTE: The maximum distance between two
connection profiles is 960 mm. For greater distances
connection profiles should be installed on the
operation side and non-operation side.
Outdoor Installation
For an outdoor installation, the connection profiles
supplied need to be cut to the correct length. These
profiles should be mounted over the entire unit length
and width.
Figure 31. Stacking, outside location
Bear in mind that different connection profiles are
used for the length and width directions of the cabi-
net.
• Length direction: Cut the connection profile sup-
plied to the correct length and mount it as described
below.

6.3. Unit with Different Widths
For units with different widths, there are four different
situations. For an indoor installation the method desc-
ribed below applies to all situations.
Indoor Installation
The top section includes 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 dimen-
sional drawing.
• Screw the projecting cross beam of the top section
to the corner posts of the bottom section.

Outdoor Installation
The top section includes a projecting cross beam that
is effectively as wide as the bottom section. For an
outdoor installation the connection profiles supplied
need to be cut to the correct length. These profiles
should be mounted over the entire unit length and
width.
• Position the top section as indicated in the dimen-
sional drawing.
The position of the top section can be as described
in one of the four situations below:

be applied over these profiles.
7. FRESH AIR INLET HOOD
The fresh air inlet hood may be supplied loose with the
AHU. In this case the air inlet hood must be attached
in the correct position as follows:
• Install the inlet hood with the screws supplied in the
correct location.
• The bottom wire grille should then be attached to
the corner post.
Figure 46. - Fresh air inlet hood
NOTE: The connection between the outdoor
air suction grille and the corner post should be
sealed.
8. ROOF COVER
For outdoor installations the roof cover should be
provided with a finish. If the casing section has a flat
top use one of the following two methods:
Method 1
• Shorten the plastic roof foil strip supplied to the
correct length. Ensure that the strip projects enough
to attach it to the side of the roof edge with a blow
dryer.
• Ensure that the roof cover already attached to the
two casing sections to be connected is clean and
dust-free.
• Attach the roof cover strip with a blow dryer over the
entire length of the joint up to the roof edge.
• Remove any excess roof foil up to the underside
of the roof edge.
Figure 47. - Roof finish. method 1
Figure 48. - Roof finish. method 2
Method 2
• Fix sealing tape to the connection profiles. Drill 160
mm holes with a 10 mm diameter through the con-
nection profiles. Be sure to remove the drill shavings
after drilling.
• Attach the casing sections to each other using bolts
and nuts (M8).
• Seal the seam on the top of the connectiong pro-
files.
