Carry out periodic inspections to detect possible damaged or broken pieces. If they are not repaired it could cause
damage to people or stuff. Before executing any maintenance operation, cut off the unit power supply.
Make sure to leave the maintenance areas open. If these areas have to be necessarily invaded by the construction of
air supply and/or lateral return ducts. Verify that the design of the ducts allow the access to the fans and the change of
the filters or that these are accessible from the other lateral.
All operations should be carried out in accordance with local safety regulations.
The reparations should be always and exclusively made by trained personal authorized by the manufacturer using
original spares. The safeties of the unit could be affected due to the failure to comply with these warnings.
INTRODUCTION
Incorrect Operation
In case of breakdowns or operation faults, turn off unit.
Periodic Inspections and Maintenance
Repairing Operations

The warranty of the unit will not respond to the damages caused by frozen water.
WARNING!
SAFETY PRECAUTIONS
Before starting any installation, service or maintenance operation, turn off the main power switch in
order to avoid electrical shock that may cause personal damages.
In case of folding electrical panels, before folding them up in order to access to the interior of the
machine, it is MANDATORY to disconnect the power supply hose from the electrical voltage, IT MUST
ALWAYS BE FREE OF VOLTAGE for this operation
DANGER
Do not touch or adjust the safety elements inside of any unit of the system. In repairs use only original spare parts
and install them properly in the same position where old parts were placed.
The installation and maintenance of air conditioning equipment could be dangerous because the system is under
pressure, some of its elements have high temperatures and include electrical components.
Do not install the unit into an explosive atmosphere.
If it was necessary to open the electrical panel and access the inside of the machine it is MANDATORY to
disconnect the power supply hose from the machine. It MUST BE FREE OF VOLTAGE for this operation.
It is generally forbidden to carry out work on electrical live parts. Protection class of the device when it is complete
opened is IP00! Be careful, do not touch hazardous voltages directly.
Check the safe isolation from the supply using a two-pole voltage detector.
Even after disconnecting the main voltage, life-threatening charges can appear between the protective ground
“PE” and the main connection.
Units with water-air, water-water or refrigerant-water heat exchangers must be conveniently protected from breaks
by freezing when the room temperature can reach values lower than 5 ºC.
In this case, it is mandatory heat, remove completely the water or add antifreeze to ensure that the freezing point
is always lower than the room temperature.
When the motor runs independently due to air flowing through or if it continues to run down after being
turned off, dangerous voltages of over 50 V can arise on the internal connections of the motor through operation
of the generator.
When there are EC motors or motors with variable speed control, the protective earth is conducting high discharge
currents (depending on the switching frequency, current source voltage and motor capacity). Earthing in
compliance with EN specifications shall therefore be observe even for testing and trial conditions (EN 50 178, Art.
5.2.11). Without earthing, dangerous voltages can be present on the motor housing.
Through use of capacitors, danger of death exists even after switching off the device in case of direct contact with
conductive parts or with parts that carry voltage due to fault condition. It is only allowed remove or open the
housing of the controller when the power supply cable is disconnected and after a waiting time of 3 minutes.

WARNING!
SAFETY PRECAUTIONS
Only qualified and trained service staff (technical service) must make the installation, commissioning and carry
out maintenance works. Unqualified personnel can only make basic tasks such as cleaning and replacement of
filters, etc.
Prevent access to children so they cannot play with the appliances.
In every visit, all precautions must be taken into account: those recommended in the installation, operation and
maintenance instructions, as well as the ones indicated in labels of the unit. Do not forget to strictly follow any
other safety precautions.
DO NOT introduce objects into the air inlets or outlets that can be drawn into the fan, people, etc.
Use safety glasses, work gloves and any other safety accessory necessary.
The fan / motor may switch on and off automatically for functional reasons.
After power failure or main disconnection an automatic restart of the fan takes place after voltage return!
Wait for the fan to come to a complete standstill before approaching it!
In the AC external rotor motor the external rotor turns during operation!
For brazing operations use a quenching cloth and take precautions to have at close distance a fire extinguisher.
This product contains fluorinated greenhouse gases, its leakage can cause displacement of air and cause
insufficient oxygen to breath.
The decomposition of fluorinated gases when being burned due to e.g. brazing operations, may cause the
existence of highly toxic and corrosive gases.
Must follow all safety recommendations.
The responsibility of all personal and material damages caused by an unplanned or inappropriate use
Product precautions
The equipment accomplishes the current technical standards at the moment of its delivery and basically it is considered
secure. The unit and its corresponding accessories should only be assembled and operate if they are in perfect conditions
and in agreement with the instructions manual of the manufacturer. Utilizations which are not in accordance with the
technical specifications of the unit (Name plate and appendix / technical data) might cause defects and other kind of
damages.
