SAFETY PRECAUTIONS
Before starting any installation, service or maintenance operation, turn the main power switch off 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 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 using a two-pole voltage detector.
Do not touch or adjust the safety elements inside any unit. For repairs use only original spare parts and install them
properly in the same position of the replaced parts.
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.
If the motor of the fan runs independently after the unit has been switched off because it is pushed by airflow,
dangerous voltage of more than 50 V may be present in some of the internal connections of the motor. In that case
the fan is working as a generator.
When there are EC motors or motors with variable speed control, the protective earthing is conducting high
discharge currents (depending on the switching frequency, the current source voltage and the motor capacity).
Earthing in compliance with EN specifications shall therefore be observed even for testing and trial operations (EN
50 178, Art. 5.2.11). Without earthing, dangerous voltages may be present in the motor housing.
Due to the use of capacitors, danger of death exists even after switching the device off in case of direct contact with
conductive parts or with parts that carry voltage due to fault conditions. To remove or to open the housing of the
controller and the terminal box for example is only allowed after the power supply cable has been disconnected for 3
minutes.

SAFETY PRECAUTIONS
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 refrigerant filters), etc.
Prevent access to children so that they cannot play with the appliances.
For each visit, all precautions must be taken into account: those recommended in the installation, operation and
maintenance instructions, as well as the ones indicated in the stickers placed on the unit. Do not forget to strictly
follow any other legal safety precautions.
DO NOT introduce objects into the air inlets or outlets that can be drawn into the fan, people, etc.
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!
Never approach the fan until it has stopped completely as it may be rotating even though it is not connected to the
power supply! Strong airflow could push it.
When the motor is provided with an external rotor, the rotor rotates during operation.
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 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 when breathing.
The decomposition of fluorinated gases when being burned during brazing operations for example may cause the
presence of highly toxic and corrosive gases.
All the safety recommendations must be followed carefully.
ATTENTION!
The responsibility of all personal and material damages caused by an unplanned or inappropriate
use will be born by the person or the operating company of the unit and not by the manufacturer.

UNIT SETTLEMENT
Make sure that the unit is slightly inclined (~2%) following the direction of the drains.
The bed frame shall be big enough and strong enough to support the unit weight.
DRAINAGE
All the drain devices are prepared with a male 3/4” gas connection (ISO 228-1, BSPP).
The unit is equipped as a standard feature with a condensate drain tray to avoid an excessive water accumulation in
the indoor side and the outdoor side.
The condensate drain pipe diameter shall be equal or larger than the unit connection depending on its length and
inclination.
If the drain line is exposed to air temperatures lower than 0 degree, it is necessary to cover it with thermal insulation
material or to use electrical heating devices to prevent water from freezing that would entail tube damage.
The drainage line shall be inclined by 2% minimum for proper water evacuation.
It is convenient to install a drain trap with proper dimensions (see diagram) or a
draining system with a condensate pump to avoid excessive water accumulation
in the indoor side and the outdoor side.

AIR DUCTS
The air duct dimensions will be determined according to the air flow and the available static pressure of the units.
They shall be designed by qualified technicians. An incorrect design may reduce the unit’s performance and may be
a hindrance when access to the unit for maintenance operations is needed (in particular where there is only one
possible access).
Use ducts made of non-inflammable material in order to avoid any risk of fire as a consequence of the deflagration of
gases. It is advisable to use insulated metal ducts.
Use flexible conduits to connect air ducts to the unit so as to avoid vibration and noise transmission.
