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 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.
ATTENTION!
• 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.
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.
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.
Before starting anyinstallation, service or maintenance operation, turn the main power switch
off in order to avoid electrical shock that may cause personal injuries.

INSTALLATION
WATER DRAIN
The indoor drain unit (of condensate water) has a 3/4” gas (ISO 228-1, BSPP) male connection.
The 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
The air duct dimensions will be determined according to the air flow and the available static pressure of the unit.
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.
