In accordance with Article 1, (m) Subject matter and scope of Regulation (EU) 2016/2281 of November 30th, 2016 concerning the
ecodesign requirements for air heating products, cooling products, high temperature process chillers and fan coil units, the equipment
mentioned in the present document shall be used only for applications of which the primary function is the purpose of producing or storing
perishable materials at specified temperatures by commercial, institutional or industrial facilities and of which space heating and/or space
cooling is a secondary function and for which the energy efficiency of the space heating and/ or space cooling function is dependent on
that of the primary function. Therefore they are not valid for comfort applications in spaces occupied by people.

SAFETY PRECAUTIONS
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 in explosive atmosphere.
Before starting anyinstallation, service or maintenance operation, turn offthe main power switch in order
to avoid electrical shock that may cause personal damages.
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 TENSION for this operation.
ATTENTION!
Only qualified and trained service staff (technical service) must make the installation, commissioning and
carry out maintenance works. Unqualified staff 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.
This product contains fluorinated greenhouse gases, itsleakage can causedisplacement of air and cause
insufficient oxygen to breath.
Must follow all safety recommendations.
In case of water tanks with ELECTRIC HEATER
Before proceeding to the start up of the unit, MAKE SURE that the water tank is completely full and
that the installation is perfectly drained of air.
The responsibility of all personal and material damages caused by an unplanned or inappropriate use
will be on the person or operating company of the unit, and will not be on its manufacturer.

TRANSPORT & RECEPTION
INSPECTION AT RECEPTION
It is advisable to examine the equipment carefully at the time of its 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. (First 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 well fixed.
Raise and set down the equipment carefully.
Do not tilt the unit more than 15 degrees during transportation. (Fig. 1) (Fig. 2).
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 temperature 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 inlet, dust and objects in general due to invasion or biological,
meteorological and/or human inclemencies.
Minimum storage temperature: -10ºC.
Maximum relative humidity: 90%.

SERVICE AREA
Make sure to respect the following measurements for the correct operation of the unit.
WATER DRAIN
The indoor drain unit (of condensate water) has 3/4” MPT connection.
Condensate drain pipe diameter should be equal or larger than the unit connection depending on the line length
and general building configuration.
The drainage line should be inclined a minimum 2% for proper water evacuation.
When drain line is exposed to air temperatures below 0 degrees, it is necessary to cover with thermal insulation
or electrical heating wire to avoid water freezing and tube damage.
It is convenient to install the drain trap with proper dimensions (see diagram).
AIR DUCTS
Air duct dimensions will be determined according to the airflow and available pressure of the unit.
Ducts must be designed by qualified technical people.
Use ducts made of non-inflammable materials in order to avoid any risk of fire as a consequence of the
deflagration of gases. It is advisable to use metal sheet duct with insulation.
Use flexible ducts to connect air ducts into the unit and thus avoid vibration and noise transmission.

ELECTRICAL INSTALLATION
Unit power supply should be within 10% of volts indicated on the unit nameplate. Damage caused by the start-up
of the unit in an incorrect voltage line is not covered by Hitecsa’s warranty.
When making electrical connections always use the unit wiring diagram.
Be sure that the compressor crankcase heater can be energized before unit start.
The line protection elements have to be placed by the installer according to the current legislation local laws.
The interconnecting wires have to be in the protection tube or electrical cable conduits, cable trays, etc.
Before starting any type of operations put in position off main power switch.

OPERATION
BEFORE START UP
Start-up has to be performed by a qualified service personnel in air conditioning.
Make sure that panels are firmly secured with screws.
Check that there is no leakage of oil or refrigerant.
Ensure that the unit is evenly leveled.
Check if there is enough space for operation and maintenance.
Before opening the electrical panel and having access to the inside of the machine it is MANDATORY
to disconnect the power supply cable of the machine which MUST BE FREE OF VOLTAGE for this
operation.
Check that the drainage is not blocked.
Always use the electrical diagram of the unit to make the connections.
Make sure that all electrical connections are properly tight.
The power supply of the unit must be as indicated on the serial plate. Damage caused by the start-up of the unit
in an incorrect voltage line is not covered by Hitecsa’s warranty.
The unit must not be supplied with any other voltage than that indicated on the serial plate. The power supply to
the unit must be within 10% of the voltage indicated on the serial plate.
Check the correct rotation direction of the fans.
The installer must place line protection elements in accordance with current legislation.
Wiring of electrical connections must be protected by a tube or other cable conduits.
Make sure if the crankcase heater of each compressor has been operating during 24 hours prior the Start Up.
Check that he air filters are clean and correctly fitted.
Check the condition and placement of grilles, diffusers, air ducts, tarpaulins, etc.
START UP
It is necessary to take notes of the air inlet and outlet temperatures to the internal coil, the volts and amps of the
compressor and motor fan, as well as the suction and discharge pressure of each compressor.
It should be remembered that it is necessary to clean the air filters after the first 4 hours of operation.
Observe, at least, 3 cooling cycle operations.
Due to the unit has frequency converters, it is essential that the protection be at least 300mA to prevent power
cuts caused by the activation of the circuit breaker.
