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 convenientlyprotected 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.
The warranty of the unit will not respond to the damages caused by frozen water.

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: 5ºC.
Maximum relative humidity: 90%.
