INTRODUCTION
Utilization
The unit will be used only for the purpose it has been designed for. Any other use does not imply any kind of liability
or responsibility from the manufacturer.
Incorrect Operation
In case of breakdowns or operation faults, turn the unit off.
Periodic Inspections and Maintenance
Carry out periodic inspections to detect possible damaged or broken parts. If these parts are not
repaired, people injuries or material damages could be caused. Disconnect the power supply of the
unit before carrying out any maintenance operation.
Make sure that the maintenance areas are accessible. If these areas have to be invaded bythe lateral
air supply and/or return ducts, verify that the design of the ducts allows the access to the fans and
that they are not a hindrance when replacing the filters. If that is not possible make sure access is
possible from the other side.
All operations shall be carried out in accordance with the local safety regulations.
Repairing Operations
The reparations shall always and exclusively be completed by trained personnel previously authorized
by the manufacturer and only original spares shall be used. The safety devices of the unit may be
damaged in case of non-compliance with these warnings.
Modifications
The manufacturer will not respond to possible warranty claims and 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.
Packaging and Replacement of Equipment
The material of the package (plastic bags, insulating materials, nails, etc.) is a potential source of
danger. Consequently, it should be kept out of the reach of children and properly recycled according
to the valid local safety regulations.
Do not mix this product with household waste at the end of its life. Due to the refrigerant, oil and other
components contained in this product, it must be dismantled by professional installers. All the
waste, depending on its nature shall be sent to recycling, composting or treatment plants, or to an
authorized management agency in accordance with the current local legislations.
Refrigerant
This product is hermetically sealed and contains R-410A which is a HFC fluorinated greenhouse gas.

SAFETY INSTRUCTIONS
Before starting any installation, service or maintenance operation, turn the main power
switch off in order to avoid electrical discharges that may cause personal injuries.
Do not touch or adjust the safety devices inside the unit. For repairs use only original spare parts and install them
properly in the same position where the old parts were fitted.
The installation and maintenance of air conditioning equipment may be dangerous due to the pressure of the system,
the high temperature of some of its parts and the electrical components.
Do not install the unit in an explosive atmosphere.
It is absolutely forbidden to carry out work on electrical live parts. The protection class of the opened unit is IP00!
Check the safe isolation from the supply by using a two-pole voltage detector.
Even after disconnecting the main voltage, life-threatening charges may appear between the protective ground “PE” and
the main connection.
If the motor of the fan runs independently after the unit has been switched off because it is pushed by airflowfor example,
dangerous voltage of more than 50 V may be present in some of the internal connection parts of the motor. In that case
the fan is working as a generator.
When the unit is equipped with EC motors or motors with variable speed control, the ground wire (depending on the
switching frequency, the current source voltage and the motor capacity) is conducting high discharge currents. Therefore
check that the earth grounding is complying with the EN standards even for testing and trial operations (EN 50 178, Art.
5.2.11). Without grounding dangerous voltages may be present in the motor housing.
The use of capacitors implies a danger of death even after switching the device off in case of direct contact with
conductive parts or with parts that carry voltage due to fault conditions. Removing or opening the housing of the controller
and the terminal box for example is only permitted after the power supply cable has been disconnected for 3 minutes.

SAFETY INSTRUCTIONS
Only qualified and trained service staff (technical service) is authorized to carry out installation, commissioning and
maintenance. Unqualified personnel will carry out basic tasks only such as cleaning and replacement of filters, or filter
cleaning (excluding the refrigerant filters), etc…
Prevent access to children to avoid that they play with the equipment.
For all visits, follow carefully all recommended precautions: the instructions recommended in the installation, operation
and maintenance manual, as well as the precautions stated on the stickers placed on the unit. Do not forget to strictly
follow any other legal safety instructions.
DO NOT introduce objects into the air inlets or outlets that might be drawn into the fan, people, etc.
Never approach the fan until it has stopped completely! Beware as it may be rotating even without electric power but
airflow for example.
The fan / motor may start and stop automatically due to functional reasons.
After a power failure or a main disconnection an automatic restart of the fan takes place when power supply returns!
The external rotor rotates during operation (for external rotor motors).
Use safety glasses, work gloves and any other safety accessory that may be necessary for the operation.
For brazing operations use a quenching cloth and make sure you have a fire extinguisher close to you.
This product contains fluorinated greenhouse gases. In case of leakage air may be displaced which may cause lack of
oxygen.
The decomposition of fluorinated gases when being burned during brazing operations for example may cause the
presence of highly toxic and corrosive gases.
Please follow all the safety recommendations carefully.
ATTENTION!
The responsibility for all personal and material damages caused by an unexpected or inappropriate use
will be born by the person or the operating company of the unit and not by the manufacturer.

TRANSPORT & RECEPTION
INSPECTION AT RECEPTION
It is advisable to examine the equipment carefully upon reception.
Check that the equipment has not been damaged during transport and that it is complete with all the parts specified in
the order and/or the options stated in the order. If this is not the case please contact the transport company
immediately (within 48h).
Verify the correct voltage of the nameplate and make sure it is in accordance with local power supply.
In case of any flaw or anomaly detected, please contact HITECSA.
RIGGING
Before moving the unit, make sure that all panels are fixed properly.
Raise and put the equipment down carefully.
Do not tilt the unit more than 15 degrees during transportation (Fig. 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 during the lifting operations.
STORAGE
If the equipment is going to be stored before the installation, please follow the following instructions in order to avoid
damages, corrosion or deterioration:
Move the equipment carefully.
Do not place the unit 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 reach values
that could lead to the activation of the safety valves.
Moreover, with decreasing temperatures water condensation may occur inside the machine and the plastic wrap.
Avoid placing other objects on top of the unit (unless this 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: -10ºC (No water must be stocked inside the equipment).
Maximum relative humidity: 90%.
