Introduction This is the instruction and operation manual for an air handling unit, hereinafter designated as ‘AHU’. Model code CCE C 15/6 – 15/6 AHU type (standard) AHU execution AHU size supply air AHU size exhaust air Legend used for AHU type CCE C casing type with thermal separation profile CCE B...
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 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.
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.

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.
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.

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.
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.
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. 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).
Figure 1: Do not climb on the AHU! 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.
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).
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.
Figure 8: Crane lug mounted Bolts and nuts are delivered with the lifting lugs and must be tightened with the torque according to Table 2. If the lifting lugs are already mounted by TRANE, the bolts must be checked before lifting of the AHU.
Figure 10: Guiding of load carrying equipment (schematic illustration) 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.
max. 15° max. 15° Figure 11: Permitted angle for load carrying equipment guidance Storage The delivery sections generally are packed in nylon. This package is suitable to protect the AHU during loading and unloading from bad weather, but not for outdoor storage. The insertion into a dry area after unloading is therefore essential for the preservation of the AHU.
Figure 12: Protection against dirt Foundation / erection Space requirements: At the location, proper maintenance and the removability of build in components shall be physically possible. Therefore, a free working space of AHU width + 300 mm shall be available. On the back site for mounting a 600 mm width passage should remain free.
Figure 13: Solid foundation and strip foundation The installation of underlayment with impact sound insulation properties and high specifications is highly recommended. It is recommended, depending on the location of the erection, to underlay the AHU with cork, Mafund plates or Sylomer strips. The used absorbent material must be adjusted to the load to achieve optimum noise insulation.
In this context, it is recommended to con- clude an insurance against damage caused by water and other liquids. TRANE is not liable for damages that may arise due to leakage of the AHU, of fittings, of pipes or hoses or due to condensation.
Assembly If climbing on the AHU is unavoidable during assembly, for example, for connect- ing the roof plates, it must be ensured by appropriate measures. For example, us- ing boards, that the weight is distributed evenly, in order to avoid bending of the roof panels.
Figure 18: Applying the sealing agent Figure 17: Sealing agent (Sikaflex) Pulling together AHU sections The AHU sections must be aligned precisely and the front sides shall be exactly parallel to the other. If necessary, some minor corrections can be made by placing steel plates under the section. The AHU sections can be pulled together with belts which attach on the base frame, as shown on Figure 19 and Figure 20.
Additionally, to the base frame, there are other possibilities for connecting AHU parts. These are listed below, ranked by the execution priority. CCE COMPACT: Easy Connection, see Figure 23 and Figure 24 Connection angle, see Figure 25 up to Figure 27 Figure 24: Connection via Easy Connection Figure 23: Easy Connection Figure 25: Hexagon bolt with locknut...
It is important, to tight initially the bolt connection at the base frame. This is to en- sure an exact connection of the AHU parts. Figure 28: Bolt connection base frame Figure 29: Bolt connection angles 5.1.4 Special features for roof AHUs and device separations at wet areas For roof AHUs as well as at device separations directly before or after a wet area (e.g.

Figure 34: Sealing the roof flange 5.1.5 Securing the position of AHUs Floor AHUs must be fixed on the foundation to secure the position.
Figure 35: Securing the position on the foundation If AHUs will be erected on roofs, a structural engineer must design the attachment of the AHU, based on the local situation and weather conditions. Doors Doors with hinged lock Door panels with hinged lock can be opened optionally to the right or to the left. Additionally, this lock mechanism enables the easy removal of the door panel from the door frame.
Beside the hinged doors, the access to the inside of AHUs with C-casing is also possible by remov- able panels. At this casing execution, the door panels will be fixed at the door frame by screw con- nections (see figure beneath). Figure 39: fixing screw with clamp- Figure 40: fixing mechanism at door Figure 41: fixed door panel (ZIB)
During the installation it must be noted, that the filter bags will not be clamped or damaged. Each filter bag must freely adjust itself in the airstream. If the filters are not included in the scope of delivery of TRANE, it must be considered that the used filters fulfills the requirements of VDI 6022.

Attention: Filters must be pushed completely to the back, so that all filters fit closely to the filter frame and an air bypass is avoided. Important: Examine if the first filter fits closely to the sealing.

(STRAUB coupling) is recommended (Figure 55). This coupling could be included optionally in the scope of delivery from TRANE, if not, then it must be provided on site. In order to avoid a damage of the copper pipe of the heat exchanger due to mechanical force, a ring is used to reinforce the cop- per pipe (Figure 53 and Figure 54).
Page 36
Other types of connections, for example welding or soldering are not recommended by TRANE, be- cause of risk of fire to neighboring materials. If one of those types of connections are chosen, the acting assembler is fully responsible for this task.
Figure 59: Drain valve Figure 60: Vent valve Drain for condensate and excess water Each drain must be equipped with a siphon. Siphons are available as accessories from TRANE. 6.2.1 Standard siphons A space-saving design of the necessary siphon height can be completed by TRANE on request.
6.2.2 Ball siphons If ball siphons with the below shown design are supplied by TRANE, then the following instructions should be observed during installation: Depending on the suction side or pressure side mounting position, the siphon body has to be in- stalled so that the direction of the arrow (see Figure 63) corresponds to the flow direction.

An electric heater is designed to heat the airflow, which is stated on the technical data sheet, from the specified air inlet temperature to the air outlet temperature. TRANE provides electric heaters with one or more stages according to customer requirements.
7.4.1 AHUs equipped from TRANE with control Units, which are supplied from TRANE with control, are limiting the supply air temperature to a de- fault value of 35 °C. The execution and function, as specified below, is supplied by TRANE.
Page 46
The 2 safety thermostats are equipped with manual reset. After triggering, the reason for stopping must be detected and eliminated before the reset of the thermostat! Thermostat 1 (Figure 70 and Figure 71) Position of thermostat body: fastened on the electric heater at the connection side, is accessible by removing the electric heater access panel.
At low temperatures and high air speeds, the condensate in the plate heat exchanger can freeze and cause its icing. For devices supplied by TRANE with control, this is prevented by pressure monitoring of the plate heat exchanger and the temporary adjustment of the supply air volume flow.

Formula A Formula B In this formula, the respective air density at In this formula, a variable air density is not taken into the fan is taken into account. account. The air density must be determined as a Instead, a "fixed" air density of 1.20 kg/m is as- function of air temperature, air humidity, sea sumed.
8.1.2 Heat exchanger The heat exchangers, fittings and valves shall be tested for tightness. Water heat exchangers Normal heating, cooling coils filled with water and additives for freeze and corrosion protection: Open vent valve. Water valve is initially only to open slightly, so that the coil will be slowly filled with water. To avoid heat stress.
If the airflow is incorrect and if you require support on this matter, please contact TRANE. 8.2.1 Resonance at fans The operation of fans at the resonant frequency (and multiples of it) must be avoided, in order to prevent high vibration loads. The resonant frequency must be determined at the AHU on site.
Maintenance TRANE AHUs are built mostly maintenance free and easy to maintain when required. The mainte- nance intervals (see Table 6) are indicative for normal operating conditions. Widely differing appli- cations may require different intervals, ask TRANE for details. The execution of the described checks and maintenance needs are necessary to ensure a permanent safety operation and func- tionality of the AHU.
All filters should be checked for tightness, because otherwise they could be sucked in and could lead to damage. If AHUs are equipped with TRANE control, then a corresponding warning message is displayed on the HMI (see Figure 76) when the differential pressure limitation is reached.
Figure 76: Warning message filter If such a warning message is displayed, then appropriate actions have to be taken immediately (e.g. change of air filters). 9.3.1 Panel filters Dry panel air filters (cleanable). The contamination level of the filter can be controlled by the differ- ential pressure drop (check every 14 days to 1 month).
Check built-in safety devices and electrical parts for proper functioning. Dampers TRANE dampers of type J are nearly maintenance free. Check for dirt, damage and corrosion, clean if necessary with compressed air or steam jet. Check the function and correct rotation. Spray the wheels with silicone spray if necessary.
Energy recovery systems The manual of the component manufacturer must be read and considered for cleaning works. 9.7.1 Plate heat exchangers Plate heat exchangers are made of highly corrosion-resistant high-grade aluminum and have no drive or moving parts. The lifetime is nearly unlimited, as long as the differential pressure between the plates does not exceed the maximum allowed.

11 Disassembly and disposal 11.1 Disassembly At disassembly, the safety instructions of chapter 2 (Safety instructions) must be considered. It also apply the instructions in chapter 3 (Reception control / unloading / transportation to instal- lation site). The housing can be disassembled relatively easy: Disassembly of the housing: Disassembly of the external panels and removal of the insulation.
11.2 Disposal The operator is responsible for the disposal of the shipment (packing material), operation (filters, tools, spare parts etc.), and for the disposal of the AHU itself. The disposal of the material must be done by qualified technicians according to the international, national and local regulations.

In the night setback mode, the rooms can be cooled with the cool outdoor air outside normal work- ing hours; all heating batteries, cooling batteries, recovery systems, humidity and air quality control are disabled. The setting is made in the menu Night setback, which can be entered directly. If a room unit or remote switch is connected, the airflow can be changed via this with a correspond- ing configuration (offset).
Speed control Similar to the airflow rate control the speed for economy, comfort and night setback mode can be set. The fans are operated at the set speed, regardless of airflow rate or duct pressure. In addition, the speed is increased by air quality control or dehumidification when the air quality is poor or the humidity is high.
Return air cascade (RetCasc) The return air temperature is used as a control variable. The supply air setpoints for the heating bat- teries and cooling batteries are calculated by the deviation between the current return air tempera- ture and the setpoints. The activation of the valves and the recovery is performed based on the de- viation between the current supply air temperature and the calculated supply air setpoints.

been configured). For example: recirculation damper requirement = 50%, i.e. with a base time of 60 minutes, the ventilator operates 30 minutes in fresh air mode and 30 minutes in recirculated air mode (in this mode, the return fan is at a standstill). In case of an additional air quality control by the recirculation damper, the air quality has a higher priority.
14.3.5 Dehumidification with recirculation damper For the dehumidification by means of the recirculation damper, the absolute humidity of the supply air and of the exhaust air is compared. In case of a higher supply air humidity (corresponds to the fresh air humidity in the fresh air mode), it is switched to recirculated mode as a function of the de- humidification requirement (see chapter 14.2.6 for more information), in order to not increase the absolute humidity content.
