INTRODUCTION
Periodic Inspections and Maintenance
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.
Repairing Operations
The reparations should be always and exclusively made by trained personal authorized by the
manufacturer using originalspares. The safeties of theunit could be affected due to the failure to comply
with these warnings.
Modifications
The manufacturer will not respond to the warranty and to the possible damages of the unit in case of electrical and/or
mechanical modifications. The unauthorized manipulation, reparation or modification of the unit will automatically
invalidate the warranty.
Refrigerant
This product is hermetically sealed and contains R-410A which is a HFC fluorinated greenhouse gas.

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, THE LINE MUST ALWAYS BE
FREE OF VOLTAGE for this operation.
It is absolutely prohibited to realize any operation on parts that are electrically powered on. The protection
class of the opened equipment is IP00!
The absence of voltaje must be confirmed by a minimum two poles voltaje tester.
DANGER
Do not touch or adjust the safety devices inside any unit of the system. For repairs use only original spare
parts and mount them properly in the same position where old parts were placed.
The installation and maintenance of air conditioning equipment may be dangerous because the system is
under pressure, some of its elements have high temperatures and include electrical components.
Do not install the unit in an explosive atmosphere.
The units equipped with water-air, water-water, or refrigerant-water heat exchangers shall be
protected properly against damage caused by frost. A proper protection is obtained by adding the
necessary anti-frost liquid so that the freezing temperature becomes minimum -2°C (6% when using
Ethylene Glycol).
Moreover when the ambient temperature in any part of the installation may reach values lower than
5°C it is COMPULSORY to protect the unit and the whole installation with additional measures such
as heating tubes, draining the unit and the whole installation for water (when the unit is not under
operation) or adding more anti-frost liquid so that the freezing point always will be lower than the
minimum temperature that the ambient air may reach.
Even after disconnecting themain voltage, life-threatening charges may appear between theprotective ground
“PE” and the main connection.
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.
Because of the 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.
The warranty of the unit will not respond to the damages caused by frozen water.

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 automatic restart of the fan may occur when power supply is
back!
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.
ATTENTION!
The responsibility of all personal and material damages caused by an unplanned or inappropriate use
will be given to the person or operating company of the unit, and not to the manufacturer.

TRANSPORT & RECEPTION
INSPECTION AT RECEPTION
It is advisable to check the equipment carefully upon reception.
Check that the equipment has not been damaged during transport and has been supplied complete with all parts
specified in the order and/or with the optional specified in the order. If this is not the case contact the transport
company immediately (within 48h)
Verify the correct voltage of the nameplate and make sure it is in accordance with the local power supply.
In case of any flaw or anomaly detected, please contact HITECSA.
RIGGING
Before moving the unit make sure that all the panels are well fixed.
Raise and set down the equipment carefully.
Do not tilt the unit more than 15 degrees during transportation, (Pict. 1).
Always transport the unit in its original packaging to the place of installation.
All units come with a particular rigging diagram of that model similar to the one shown below. Be sure to hoist the
machine through the points indicated in the diagram.
Make sure that the unit is balanced, stable and without any deformations when it is lifted.
STORAGE
If the equipment is going to be stored before the installation, please follow the instructions below in order to avoid
damages, corrosion or deterioration:
Move it carefully.
Do not place the machine in places exposed to ambient temperatures above 50ºC and preferably keep the unit
away from direct sunlight.
Avoid placing the unit with plastic wrapping protection under the sun as the pressure of the circuits could assume
values that could lead to the intervention of the safety valves.
In addition, when cooling, water condensation occurs inside the machine and the plastic wrap.
Avoid placing other objects on top of the unit (unless it is done within the limits of the overlap planes indicated on
the packaging, etc. Follow these indications).
Avoid prolonged storage before installation, water penetration, dust and objects in general due to invasion or
biological, meteorological and/or human impacts.
Minimum storage temperature: 5ºC.
Maximum relative humidity: 90%.
