5.3 - Transport
■ Do not allow any disruption to the ow
■ Follow the handling instructions afxed to the packages
■Follow the lashing instructions in the document provided
■Do not stand on the packages
■Do not place anything on top of the packages
■Strap the packages onto the deck of the truck
■ Only textile straps are authorised (lifting and coupling)
■Use the dedicated option for container transport
6 - STORAGE
■Store the units at a temperature of between -40 and +60°C (temperature range for standard units). For options, see the relevant
description.
■Protect the units against impacts and ensure that they only support their own weight.
■ Place the units on rm, at and level ground. For storage in very windy areas, afx the unit to the ground using straps or cables.
■Leave the blanking trim for the pipes in place before connecting the unit.
■ For long-term storage (over 3 months), ll the exchanger with an inert gas and seal the pipes using caps. This is necessary to
prevent the formation of condensation and oxidation. Warning: do not exceed the maximum operating pressure indicated on the
data plate.
■For long-term storage, it is recommended to place the units in an area protected from adverse weather conditions.

7 - LOCATION
■For structures with a "special" seismic risk, please consult us.
■ Before setting up the unit in its intended location, the installer must check the following points:
-The unit must be installed outdoors in an area protected from ooding. Ensure that all conditions have been taken into account
(negative outdoor temperatures, corrosive atmosphere, altitude, etc.)
-The ground surface or structure must be level and strong enough to bear the unit's weight.
-Raise the unit if it is installed in a snowy area, in order to ensure a sufcient air intake height.
-At the design stage, check that the installation location is compatible with the unit's sound level.
-Protect the unit from sandstorms using the appropriate infrastructure.
-Waste from vegetation is a major factor contributing to the clogging of the coil; avoid installing the unit close to deciduous trees.
-Do not install the unit near hot air extraction duct outlets.
■The installer must take all necessary precautions to limit the recycling of hot air and ensure a good air supply to the unit.
7.1 - Maximum permitted wind speed
■ Maximum permitted speed once the unit is secured to the oor: 100 Km/h
■ For speeds > 100 Km/h, contact us.
7.2 - Floor mounting
Fluid input side
Allow at least 3 support zones under each foot; these zones should all be stable and on the
same horizontal plane.
(Models 6, 10, 14, 18) (Models 8, 12, 16, 20)

8 - INSTALLATION RECOMMENDATIONS
■ Ensure sufcient devices are provided to guarantee the protection of persons and property, and to enable maintenance operations
to be carried out in complete safety.
■ If a malfunction would have signicant human, environmental or nancial consequences, take appropriate steps to limit the effects.
■ Ensure that the installation complies with the legal texts and codes in force in the country of operation, and that it complies with the
safety rules applicable to the site where it is being used (explosive atmosphere, for example).
■ If necessary, afx to the machine the hazard symbol corresponding to the uid in accordance with current standards.
■ Install burn hazard signs wherever the internal temperature of pipes exceeds 65°C.
■Fit safety devices to prevent the uid temperature or pressure from exceeding the values indicated in the order. Approval for operation
at higher conditions must be obtained from us.
■ The unit must be tted with an immediately accessible emergency stop device; this visible device must allow the electrical supply
to the unit and its accessories to be cut completely.
■Ensure that cutting off the electrical supply, whether intentionally or accidentally, does not jeopardise the process.
■Use the mounting holes and, if necessary, reinforce the anchoring system according to the wind conditions.
■If the unit needs to be installed on a framework, this structure must be calculated based on the weight of the unit during operation
(full), equipped with all its accessories.
■If using rubber mounts, use a rigid frame which locks the feet together.
■ The nned components may be damaged if the unit suffers impacts or is hit by falling objects. Take appropriate steps to protect it,
by adding a protective screen, for example.
■If there is a risk of freezing while the system is operating, use a device designed to prevent this.
■Install venting and draining devices and shut-off valves.
■Connect the piping to earth in accordance with an overall study of the installation.
■ For any accessories, refer to the specic guides.

9 - CONNECTIONS
9.1 - Electrical connection
■All wiring must be connected in accordance with the regulations that apply to the installation site (e.g. NF C 15100 in France).
■In all cases, refer to the "ELECTRICAL CONNECTION" document or wiring diagram attached to the unit.
■ Follow the electrical supply specications indicated on the data plate.
■ The phase unbalance must not exceed ±2% for voltage.
■For units without wiring or with an electrics box option, the motors are partitioned in pairs: M1+M2 – M3+M4 - …
The motors must be controlled by stage in a single partition.
If any of the above requirements are not met, immediately contact your energy supplier and make sure the unit is not switched on until
the necessary corrective actions have been taken. Failure to do so will automatically void the warranty.
It is your responsibility to protect the unit from mains voltage spikes and voltage spikes caused by lightning. Depending on
the geographic location and the type of mains network (buried or overhead), local regulations may require that a lightning rod
be installed. Failure to comply with the requirements of standards in force in the country of installation
(e.g. NF C 15100 in France) will void the warranty.
-Before connecting, make sure that the power supply cable is disconnected.
The terminal boxes on the motors for units without the terminal box or electrical cabinet option must be directly connected taking all
the necessary precautions in order to avoid:
-electrical connection errors which can damage the motors or impair performance
-water ingress in the terminal boxes (e.g. if the cover is not closed properly) which damages the motors
-people falling from a height when making electrical connections for units installed high up
9.2 - Fluid connection
■Never introduce foreign bodies into the circuit.
■ The connection pipes and the regulation or insulation equipment must be set up and supported so as to ensure they do not exert
any force on the coil piping (pressure, torsion or exion). It is recommended to use exible connectors on the connections to prevent
water hammer.
■ Positioning of pipes: connect all piping on the unit (see dimensional drawing)
■If brazed/welded connections are used, take appropriate precautions to ensure that welding residues do not enter the circuit.
9.3 - Connecting a speed regulator
■ A regulator must be commissioned by a specialist, as an incorrect choice/conguration could cause electromagnetic interference and
damage to the motors. Minimum precautions:
-Use a shielded cable upstream and downstream of the regulator.
-The frequency must be between 25 and 50 Hz.
-Fit a DU/DT lter between the speed regulator and the fans.
