8 - INSTALLATION RECOMMENDATIONS
■Ensure sufficient 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 significant human, environmental or financial 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, affix to the machine the hazard symbol corresponding to the fluid in accordance with current standards.
■Install burn hazard signs wherever the internal temperature of pipes exceeds 65°C.
■Fit safety devices to prevent the fluid 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 fitted 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 (particularly for vertical units).
■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.
■If objects or hail fall on the unit, there is a risk that the finned components may be damaged (horizontal forced-draught units). 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 specific 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 CONNECTIONS" 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.
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 making any connection, check that the power supply cable is not powered on.
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
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.
Special note for condensers:
■Refrigerant connections: The refrigerant connections between the condenser and the internal machine, as well as the leak tests,
must be carried out by a specialist using a method in accordance with best current practices and applicable standards and
regulations. Units are delivered pre-charged with nitrogen at 0.5 bar with piping blanked.
-Blanking with brazed plugs: remove the plugs by heating them with a blowtorch
-Blanking with pressed metal: use a pipe cutter to cut off the end of the pipe no more than 10 mm from the end.
■Inlet/outlet according to stickers afxed to the manifold close to the orice.
■On grounds of hygiene, SAWING AND GRINDING ARE FORBIDDEN. Use a pipe cutter.
9.2 - 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 filter between the speed regulator and the fans.
10

10 - OPERATION
10.1 - First commissioning
■Read the guides for commissioning any accessories very carefully and follow all advice.
■Check that the supply voltage corresponds to that given on the data plate.
■Retighten the connections of the electrics box.
■Switch the unit on and check that all the fans are turning in the correct direction (direction of rotation shown on the labels).
In the event of abnormal noise coming from the fan motor assemblies, immediately switch off the power supply and contact us.
■Ensure that the hydraulic circuit(s) are clean.
■Start charging by bleeding the air remaining in the circuit using the vents provided in the top section.
■Start increasing the pressure, then check that the pipe connections are fully sealed.
10.2 - In the event of faults
Please contact us if you require any help. Before contacting your CIAT agency, please check the following points:
-Are all fans turning in the correct direction? (check this against the labels)
-Is the supply voltage correct?
-Are the motors running at the correct speed? (check the input current)
-Has the uid direction been reversed during connection of the coil?
-Are the ns of the coil clogged?
-Are there any issues relating to air recycling or a poor air supply?
10.3 - Recommendations for use
Scaling and corrosion have a very negative effect on the operation and service life of the units. Therefore, only use treated
water or authorised fluids (check the compatibility of any additives with the drycooler's materials).

12 - EC FAN MOTOR ASSEMBLIES
12.1 - EC motor protection
■These motors feature integrated protection and monitoring devices. They are protected against thermal overload of the electronic
components and motors, and against any failure of the Hall effect sensors to analyse the position of the rotor.
■These faults are indicated by a change of state in the KL2 fault relay (terminals COM-NO-NC). This is a potential-free changeover
relay, with a breaking capacity of 2 A/250 VAC cos phi = 1.
■List of faults:
-In the event of a thermal overload on the motor/electronic controls, or a Hall effect sensor fault:
The fan stops and cannot be restarted. The fault is indicated by a change of state on the KL2 relay. The fan can only be
restarted by powering off for 20 seconds then powering back on again (after the source of the fault has disappeared, otherwise
the cycle restarts).
-Rotor blockage:
In the event of accidental rotor blockage, the fault is indicated by a change of state on the KL2 relay. When the blockage is
cleared, the fan automatically restarts.
-Under voltage:
The motor accepts a nominal voltage/frequency range of 380 to 480 V/50 to 60 Hz with no notable modication to a handling
performance. Between 380 and 290 V, the fan continues to operate with degraded performance. If the voltage drops below 290
V for 5 seconds, the motor stops. The fault is indicated by a change of state on the KL2 relay. The motor will restart when the
voltage returns to its nominal value.
-Absence of phase:
If one of the 3 phases is absent for more than 5 seconds, the motor stops. The fault is indicated by a change of state on the
KL2 relay. The motor will automatically restart 10 - 40 seconds after the 3 phases return. Phase inversion has no effect on the
direction of rotation of the motor.
12.2 - Fan with EC motor (3-ph 380 V to 480 V 50/60 Hz)
■On a 3-ph/380-400 V/50/60 Hz network, EC motors will have different rotation speeds depending on the control signal.

14 - MAINTENANCE
14.1 - Recommendations for maintenance
■Make sure power to the unit has been disconnected before servicing.
■Reduce the temperature and pressure before carrying out any work on the bundle.
■ For drycoolers with an expansion vessel, lower the temperature before opening the ller cap (valve cap).
■ Do not make any modications without our agreement.
■Do not walk directly on the unit.
■ Depending on the type of uid (e.g. water without anti-freeze), take precautions to prevent the risk of freezing, which would destroy
the coil. As standard units cannot be completely drained by gravity, protect from freezing as follows:
1. Drain the circuit using the bleed nozzles and the vent located on the manifolds or pipes.
2. Circulate compressed air through the circuit until all water has been removed.
3. Fill the circuit with anti-freeze and close the circuit.
■For regulated units, do not forget the mandatory inspections.
■In winter, do not allow snow to accumulate around and on top of the unit.
■Periodically check the condition of the coatings and apply touch-ups as needed.
14.2 - Maintenance frequency
ACTION FREQUENCY

(1) Frequency to be adapted to the environmental conditions.
14.3 - Information relating to condensers
The sealing test must be carried out in compliance with EC regulation no. 517/2014 relating to certain greenhouse gases.
R410A, R134a and R407C are refrigerant gases with the following environmental impact:
1/ No impact on the ozone layer.
They have an ODP (Ozone Depletion Potential) index of 0
2/ Impact on the greenhouse effect: Global Warming Potential (GWP) of each gas.
- R410A -------- GWP = 2088
- R407C -------- GWP = 1800
- R134a -------- GWP = 1430
-Users must ensure that periodic leak testing is carried out by qualied personnel based on the number of tonnes of CO2
equivalent:
≥ 5 tCO2eq ≥ 50 tCO2eq ≥ 500 tCO2eq
Frequency of check
Without leak detection system Every 12 months Every 6 months Every 3 months
With leak detection system Every 24 months Every 12 months Every 6 months
Refrigerant
charge*
R410A (GWP = 2088) ≥ 2.39 kg ≥ 23.9 kg ≥ 239 kg
R407C (GWP = 1800) ≥ 2.77 kg ≥ 27.7 kg ≥ 277 kg
R134a (GWP = 1430) ≥ 3.49 kg ≥ 34.9 kg ≥ 349 kg
* The refrigerant charge and the number of tonnes of CO2equivalent will be given by the installer.
- Users of any system subject to leak testing are required to keep a log of the quantities and types of uids used, (added or
recovered), and to include the dates and results of leak tests, as well as the name of the technician and the technician's company.
-A leak test must be carried out one month after any leak repairs.
-System users are responsible for collecting used refrigerant and having it recycled, regenerated or destroyed.

14.4 - Cleaning the coils
■Switch off the unit.
■ If the unit is tted with a "protective screen" option, remove this to access the coils.
■ If the ns are damaged, straighten them using a comb.
■In the event of minor fouling (non-clogging dry residue or dust, leaves, wires, etc.):
-Counter-ow supply air: dry air up to 30 bar.
-Where possible, periodically reversing the ow of air generated by the fans can prevent this. This operation is not possible if the
unit is equipped with EC motors.
■In the event of moderate fouling (moderate clogging due to dry residues, damp dust or grass, insects, etc.):
-Use a high-pressure (HP) steam cleaner with a at jet nozzle (25°).
-Max. pressure 100 bar
-Steam: max. 140°C
-Min. distance between the nozzle and the ns = 200 mm
-Cleaning uid: municipal water with pH neutral detergent (pH 7). Avoid alkaline detergents.
-Flushing with clean water using the same adjustment parameters.
■IMPORTANT: the use of detergent is prohibited for cleaning ns with a BLYGOLD®, ALTENA®or HERESITE®coating.
Recommendations to follow when using a HP cleaner
1. Ensure the high-pressure cleaner has reached its correct temperature. Check that the
uid exiting the nozzle is steam rather than liquid.
2. Hold the high-pressure cleaner's lance at a distance greater than that recommended, then
move forward into the working position.
3. Direct the at jet created by the nozzle onto the surface of the ns and perpendicular to
them. An angled position risks pushing the ns together and a parallel position risks pushing
them apart.
4. To prevent residue from being pushed inside the nned block, it is often useful to perform
an initial wash against the air ow direction (at the discretion of the operator and depending
on the fouling level).
5. Some detergents may damage the unit's paintwork.
14.5 - Removing and retting a fan
■The removal of a fan is a simple operation, however special care must be taken during handling, in particular:
-Do not pull on the blades.
-Place the fan motor assembly on a safe surface away from areas of activity.
-If the unit is to be shipped, provide the necessary protection and packing materials.
-Do not remove the panel.
■The fan must be repaired if any of the blades are bent.
