This information applies both to the ratios of the supply air and the exhaust air.
1.2 Intended use / foreseeable misuse
1.2.1 Intended use
The AHU is used, depending on the chosen purpose for
-transportation and conditioning of air in and out of buildings, in which humans stay
-creation of a desired room air quality in the occupied area of humans
-creation of an acceptable comfort or desired working conditions
-depending on the AHU type, the air conditioning is done primarily by
oAir change
oControl of air temperature and air humidity
oFiltration of normal polluted air
oFiltration at specific requirements (clean room and so on)
The AHU is suitable for
-operation in the range of the agreed design data
-an ambient air temperature range of – 20 °C to + 60 °C at installation site, if electrical/electronic
components are mounted on the outside of the AHU, then + 40 °C maximum
-a minimum temperature of the transported air of -20 °C (if necessary, freeze protection
measures must be installed)
-a maximum temperature of the transported air of +60 °C
-inside the AHU at motors and other electrical/electronic components up to +40 °C maximum
The operation at other conditions must be agreed in writing. Unless otherwise agreed, the design of
the AHU is for a nominal density of the air of 1,20 kg/m³.
Components provided by the customer
If it is planned and agreed, that TRANE installs components in the AHU, which are provided by the
customer, TRANE only accepts liability, if there are significant mistakes in construction.
The warranty for proper functionality of the provided components as well as the component con-
cerned safety requirements is excluded.
For AHUs with components provided by the customer no CE-conformity is generated due to this
reason.
Changes of the AHU by the customer
Attention!
If there are any changes to the AHU undertaken by the costumer after delivery, then the warranty
becomes invalid. Subsequent changes of the AHU, which are not authorized by TRANE, are the
sole responsibility of the executing person, concerning functionality as well as safety aspects.
1.2.2 Foreseeable misuse
Other than above use, is considered as improper and must be excluded totally:
-The commissioning of equipment, prior to performing the steps indicated in the assembly in-
structions and operating with the fan section door open, is a serious security risk.
-Opening the AHU, without securing the main switch in the off position, represents a massive se-
curity risk.

-The operation of an AHU equipped with an electric heater while the fan-motor is cut off, or if the
fan is working at a limited airflow, for example, caused by closed dampers or similar and with
the electric heater in operation produces an imminent fire risk.
-The operation in an explosive atmosphere is prohibited.
-Handling of air with corrosive / aggressive components.
-Pressure-sided doors can detach suddenly while opening. So, there is a risk of injury for the
user. See chapter 5.2 Doors.
1.3 Modular design
Because of the modular AHU design, the instruction manual covers all the possible sections and
components which can be delivered. The ordered range is smaller and can be seen on the technical
data sheet - see chapter 1.4 (Documentation).
In this manual, treated parts/components that are not part of the delivered AHU, can therefore be
disregarded.
1.4 Documentation
The AHU will be delivered with the following documentation:

10/115 V07-19.0
Indication to avoid damage
In addition to the contents of this manual, the instruction manuals of the component manufacturers
must be followed. These will be delivered separately or can be downloaded from the homepage of
the component manufacturer. In case of contradiction between this manual and instruction manuals
of the component manufacturer for safety instructions, the most restrictive interpretation is valid. At
differences between this manual and the instruction manual of the component manufacturer, the in-
struction manual of the component manufacturer has to be applied. In case of doubt, please contact
your TRANE office.
2 Safety instructions / Guidelines to conformity to laws and directives
2.1 CE-conformity / installation instructions for safe operation
2.1.1 CE-conformity / incorporation declaration according to Machinery Directive
2006/42/EC
An AHU (or any part thereof) supplied by TRANE is by definition of Machinery Directive 2006/42/EC
an incomplete machine, because it is limited in function and is only a part of the building system.
Accordingly, for a safe operation before the initial start-up, the general in chapter 2.1.2 (Installation
instructions for the proper installation in the building system)and in particular in the following
chapters described on-site work must be carried out for a safe operation.
Depending on the scope of supply, a CE-conformity declaration or a declaration of incorporation will
be issued. A declaration of incorporation will be issued, if supplementary work on site is necessary
to gain the CE-conformity. This applies if no frequency converter, which is necessary, or no filter
manometer is included in delivery (see chapter 2.4).
2.1.2 Installation instructions for the proper installation in the building system
For the proper installation of AHU equipment and the safe operation of the system, depending on
the configuration of the AHU, before the first start at least, the following points must be implemented
or upgraded and is the responsibility of the client:
Assembly of delivery sections
The delivery sections of the AHU must be assembled and linked together, according to the drawing
supplied on the inner face of fan section door. See the chapter 4 (Foundation / erection).
Secure inlet and outlet openings
All the inlet and outlet openings must be connected to ducts or respectively equipped with grilles, to
prevent persons accessing from the outside to moving parts (such as fan wheels) during operation.
Main switch
See chapter 7.2 (EC motors).
Installation of filters
See chapter 5.4 (Airfilters).

V07-19.0 11/115
Temperature limitation
Ensure that a control system is fitted and that the AHU is only operated with a supply air tempera-
ture below the allowable maximum (see chapter 1.2.1 Intended use, when not stated otherwise in
the technical data). For this purpose, the continuous monitoring of the supply air must be ensured
on site.
Measures regarding noise attenuation
As a basis for on-site sound measures calculation (such as for sound attenuators) the on request
available sound data can be used. For information regarding the emitted sound power level over the
openings see the technical data sheet, which is available on request – refer to chapter 10 (
Information on airborne noise emitted by the AHUs - on request).
Measures to minimize the risk of water damage or damage caused by similar media
See chapter 4.2.2 (Actions to prevent potential risks).
Connection to an external protective conductor system
See chapter 7.1 (Connecting to an external protective conductor system).
Electric heater
Installation (if not supplied by TRANE) and connection of thermostats for safety shutdown, see
chapter 7.4 (Electric heaters).
Siphons
Connecting according to chapter 6.2 (Drain for condensate and excess water).
Flexible connection
Installations (if not supplied by TRANE) refer to chapter 6.3 (Duct connection – airside connec-
tion to AHU).
Heat exchanger
For all heat exchangers which are connected on-site, irrespective of the medium used (water, water-
glycol mixture) it must be ensured by the customer that the resulting assembly meets the pressure
equipment directive, PED '2014/68 / EU.
Field equipment for roof AHUs
On site mounted field devices for roof AHUs, e.g. damper position motors or pressure switches must
be weather-protected in case of insufficient IP class and - depending on the installation situation -
possibly also protected against icing.
Freeze protection
The customer must ensure sufficient freeze protection measures. See indications in chapters 4.2.1
(Potential risks that may arise at the erection site), 4.2.2 (Actions to prevent potential risks),
6.4 (Freeze protection measures)and 7.5 (Frost protection for plate heat exchanger).
Venting, draining of heat exchangers
See chapter 8.1.2 (Heat exchanger).

12/115 V07-19.0
2.2 Indications for minimizing specific hazards
2.2.1 General indications
An improperly performed maintenance can pose a security risk!
Risk of thin sheets, when working on AHU
During work on AHU (or on parts), there is a substantial risk of cutting with thin
sheets as e.g. roof sheets, fins of heat exchangers, corners and edges - Use per-
sonal protective equipment: wear protective helmet, gloves, safety shoes and long
protective clothing.
Lighting
For work on AHU (maintenance and inspection work) make sure there is adequate lighting.
Firefighting in case of fire
In general, the local fire protection regulations must be observed.
-If the AHU is part of the smoke extraction concept, then the specifications
of this concept have to be observed.
-Otherwise, the power supply of the AHU must be interrupted immediately at
all conductors. In addition, the dampers must be closed to consequently
prevent oxygen supply and fire spread.
Exposure to harmful substances in case of fire
In case of fire, some materials can produce harmful substances. In addition, harm-
ful vapors can escape from the AHU. Therefore, severe respiratory protective
equipment is required and the danger zone has to be avoided.
Exposure to rotating parts / hot surfaces / electrocution
When working on and/or in the AHU note the following risks:
Indentation of body parts in moving parts (fan impeller, external damper gear
wheels ...).
Burns and scalds on hot AHU components such as heat registers, heat exchang-
ers, ...
Electrocution on current-carrying parts such as electric motors, frequency convert-
ers, electric heaters, control cabinets, interior lighting etc.
Therefore it must be ensured that prior to working on and/or in the AHU, that…
-all current-carrying parts, such as cable plug connections, fan motors, valves, motors and elec-
tric heaters are disconnected from the power supply by using the main switch (emergency stop)

V07-19.0 13/115
and that the switch is locked in position 'off' in order to effectively prevent a re-activation during
the work. The housing of the AHU interior lighting (can have separate supply) is not current-car-
rying.
-all moving parts, especially the fan wheel, motor and heat wheel have come to a standstill; wait
at least 5 minutes after switching off before opening the doors.
-Remove the key from doors with door lock before entering in the casing of the AHU. Keep the
key out of reach of unauthorized persons.
-Check that the hot media supply is interrupted and all the heat registers, heat exchangers, etc.
are cooled to ambient temperature.
In case of standstill of the plant (e.g. power failure), make sure that the main
switch is always checked. Only when it is in the off position and secured against
unintentional restart, appliance doors can be opened, cable plug connections can
be disconnected and work on the device can be carried out.
Start of the AHU
Ensure after working and before the start that…
-nobody is in the AHU.
-all protective devices are working, (optional safety devices such as the door guard mounted
again) and doors equipped with door locks are locked and the keys are removed – refer to
chapter 5.2 (Doors).
Storage of potential energy in gases and fluids
All heat exchangers can be operating up to a maximum pressure of 15 bar. If the
fluid is under higher pressures, the safety and tightness cannot be guaranteed.
Preventing the risk of explosion and fire spread
To prevent the fire spreading, fire dampers shall be installed into the ducts be-
tween the fire compartments.
Prevention of exposure caused by antifreeze agents
Avoid body contact with antifreeze agents, because they may cause burns. Always
wear appropriate protective clothing (e.g. gloves, goggles, ...).
In case of fire, avoid the danger zone and meet different safeguards. It is recom-
mended to wear a mouth guard, because of the risk of poisoning by inhaling the
vapors.
Prevention of hazards caused by suddenly falling out door panels while opening of remova-
ble panels
Removable door panels can fall out after detaching the connections and lead to inju-
ries. Particular care should be taken when removing pressure sided doors because
they can be firmly in place then suddenly detach. The user must be able to carry the
weight of the door. At doors with a surface of > 0.5 m² two persons are necessary.
Please note the instructions on the AHU and subsequent instructions exactly.

2.3 Conformity to laws and directives
2.3.1 General
The AHU will be built and delivered according to the agreed specifications and exactly to your re-
quirements. It is important to note that the AHU is a part of a system and that the AHU is only after
assembling and connection to the system ready for operation. It is normal, that the AHU is ready for
operation only after installation-work.
Depending on the particular application and country-specific requirements and laws it is possible,
that the AHU does not meet the valid requirements at the ordered state at delivery.
Therefore, you – the customer and installer of the AHU – are obligated – before commission-
ing of the AHU to check the conformity of the entire system to the valid laws and directive.
If there are any doubts about the conformity of the AHU with the local (on site) valid laws and direc-
tives, the AHU is only allowed to be put into operation, if the conformity of the AHU in the system is
unequivocally guaranteed.
2.3.2 Conformity to VDI 6022
The AHU of the series CCE Compact in basic design complies with the hygiene requirements of VDI
6022.
Basin in the outside-air intake section
The AHU CCE Compact is not equipped with a basin in the outside-air intake section as standard.
In order to fulfill the requirements of VDI 6022 a tub must be installed in the area of the fresh air in-
take section, depending on the location of the AHU. Additionally, the entrance of water, fog, snow
etc. has to be prevented by a measure on site. If necessary, an additional intake plenum with drain-
pan has to be provided.
On request an appropriate plenum can be offered. For this purpose, contact your TRANE-partner.
Maintenance-friendly accessibility of all components
All components of the air handling system have to be accessible on inflow and outflow side. This
means that ducts with access doors have to be provided on site in order to provide accessibility.
Intake grids at openings of outdoor AHUs
According to VDI 6022 all intake openings have to be equipped with an intake grid (mesh size 20 x
20 mm).
Such intake grids are optional and can be ordered on request. However, the mounting of intake
grids at all intake openings has to be ensured on site.
Door adjustment at outdoor AHUs
Hinged doors at outside AHUs have to be secured by an appropriate fixture against shutting. Such
equipment is optional and can be ordered on request. Anyway, the system operator is responsible
for ensuring such appropriate measures.
Manometer for filter monitoring
According VDI 6022 at a volume flow > 1000 m³/h manometer have to be installed for filter monitor-
ing. These could be ordered at TRANE as an option. However, the filter monitoring has to be en-
sured on site.

V07-19.0 15/115
2.4 ErP conformity according to directive (EU) 1253/2014
The ErP directive (energy related products) determines minimum requirements to the efficiency of
air handling units. Important points, for which the system operator is responsible, are:
Multi staged control
All AHU`s, except those with double application, have to be equipped with multi staged drive or
speed control for fans. See chapter 7 (electrical connection).
Filter change indicator
If one or more filter stages belong to the AHU equipment, then they have to be equipped with an op-
tical display or an acoustic warning in the controlling. They will be triggered if the pressure drop at
the filter exceeds the maximum permissible value. See chapter 9.3 (air filters).
If above mentioned equipment is not included in delivery by TRANE, it has to be provided on site.
2.5 Staff selection and qualification
All persons, who are authorized to work on the air conditioner, must have read and understood the
complete manual - in particular chapter 2 (Safety instructions). Until this task is completed, the
person may not begin to work on the AHU.
All work must be carried out by professionals who have sufficient technical training, experience and
sufficient knowledge of…
-Locally applicable safety and occupational health rules
-Locally valid accident prevention regulations
-Locally applicable standards and approved rules of practice.
All professionals have to recognize and assess the work appropriately and recognize and avoid po-
tential hazards.
Execution of the assembly, installation, electrical connection, commissioning and disposal:
-by qualified electricians and AHU technicians.
Execution of maintenance / monitoring of the operation:
-by technical staff or trained personnel and qualified electricians and AHU technicians.
Subsequently, warning triangles indicate warnings that must be adhered to minimize risks to per-
sons who are entrusted with the work on the air conditioner.
3 Reception control / unloading / transportation to installation site
3.1 Reception control
-Upon arrival of the equipment, please check immediately the package for completeness and any
damage.
-Loose supplied parts and assembly materials are in a nylon bag or a box in the AHU.
-If damages are found, immediately complete a damage report and send it to TRANE. Only then
the transport company can make the claim with the insurer (Note damage on the shipping docu-
ments with date and signature in the presence of the carrier). Complaints about apparent dam-
aged or missing parts of the delivery cannot be subsequently recognized, if procedures are not
followed. In case of complaints please inform immediately the TRANE office.

-Depending on the material used and the environmental conditions, a superficial corrosion may
occur on components like e.g. motor shafts, fan shafts, clamping bushes, sheet cutting edges,
and so forth. The resulting corrosion layer protects the underlying material from further corroding
and does not represent a defect of the component or the device (see also chapter 9).
The packaged delivered goods may include multiple parts of the device. In this
case, each part is secured against falling. Attention: narrow parts may tip over after
removing the safeguard. Secure narrow parts against tipping over!
Thin sheet metals like roof, edges or fins are a source of injury! Gloves, safety
shoes and long work clothes must be used.
Devices shall not be climbed. If unavoidable: weight must be compensated by use of boards.
Figure 1: Do not climb on the AHU!
3.2 Lifting by forklift / lift truck
In accordance with the TRANE drawing the AHU will be delivered as monobloc or more delivery
section(s). The AHU parts or the monobloc are delivered on pallets and can be unloaded and
moved by forklift or lift truck. Forces must always act on the base frame, see Figure 2.

Figure 3: Transport incorrect

V07-19.0 17/115
Center of gravity must be centrally located between the forks (see Figure 4). For large parts use
several lift trucks.
Figure 4: Center of gravity centrally between the forks
For the overlifting directly by crane from the truck applies the following chapter 3.3
(Lifting of CCE Compact AHUs).
3.3 Lifting of CCE Compact AHUs
The AHU of the series CCE Compact in basic form is usually delivered as monobloc, see Figure 5.
If there are any additional AHU sections, the same specifications apply for lifting the AHU, which are
described below.
Figure 5: Delivery AHU monobloc

18/115 V07-19.0
-In addition to the actions mentioned here, the instructions according to chapter
3.4 (Further necessary actions for the overlifting of both, delivery sec-
tions on crane lugs as well as monoblocs)have to be observed.
-Parts of the AHU may only be lifted with lugs individually - never bolt parts to-
gether before lifting.
-Lateral load on lifting lugs is not allowed.
3.3.1 Weight specifications of CCE Compact AHUs and additional parts
Depending on the AHU type, the AHU or additional sections have following weights, see Table 1.
The delivered crane lugs may be used for lifting CCE Compact AHUs which have these maximum
weights. It is required, that the weight is equally distributed on all 4 correctly mounted crane lugs. If
there are more than one AHU part, they must be lifted separately.

3.3.2 Mounting of crane lugs
4 crane lugs are supplied in two versions – mirror inverted. These lugs must be mounted at the spe-
cific positions at the base frame of the AHU.
Execution of the lifting lugs (see Figure 6):
1. Right-side type
2. Left-side type
Attention to correct mounting of the crane lug according Figure 8.

3.3.3 Lifting of CCE Compact AHU by crane lugs
-The load effect has to take place uniformly across all four crane lugs.
-The definition of the load carrying equipment is the responsibility of the executing company.
-The correct guidance of the load carrying equipment according to Figure 10 must be observed.
-After the pre-positioning of the delivery section at the desired position, remove the lifting lugs
and use them for the next delivery section.

3.4 Further necessary actions for the overlifting of both, delivery sections on
crane lugs as well as monoblocs
-The AHU sections or monoblocs must be lifted with appropriate equipment
e.g. belt with hook.
-The recommended minimum load capacity per load carrying equipment is
50% of the total weight of the delivery section or monobloc.
-The length of the load carrying equipment must permit a favorable course, see
Figure 11.
-The course of the load carrying equipment must be chosen so that overhang-
ing attachments, roofs and the like will not be stressed or damaged.
-Load carrying equipment shall not run over sharp edges and is not allowed to
be knotted.
-The load carrying equipment must be secured against slipping off.
-After the section is lifted slowly from the floor for a few centimeters, stop the
operation. Now check the correct course of the load carrying equipment and
that the lifting and fastening elements are all secure and safe.
-Avoid jerky lifting.
-Make sure that nobody is under the raised load.
-Never lift AHU sections or monoblocs on heat exchanger connections or other
attachments.
-The load carrying equipment is not permitted to exceed an angle of maximum
15 ° to the vertical and must be spread apart to avoid damage to the casing,
refer to Figure 11.
