SAFETY PRECAUTIONS
DANGER
• 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.
• Do not touch or adjust the safety elements inside of any unit of the system. Use only original spare parts in
repairs and install them in the same position where old parts were placed.
• The installation and maintenance of the 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 the explosive atmosphere.
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.
• 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.
• All safety recommendations must be followed.
Before starting installation, service or maintenance, turn off the main power switch in order
to avoid electrical shock that may cause personal damages.
WARNING!
In case if the existance of water tanks with ELECTRIC HEATERS.
Before starting the equipment, make sure that the water tank is completely full and that the installation is
perfectly drained of air.
WARNING!

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%.
