I.1 MACHINE DESCRIPTION
I.1.1 DECLARED CONDITIONS OF USE
MCAEBY are air cooled condensing. Range is equipped with axial fans.
Use is expected to civil air-conditioning systems, and the correct
operation of the unit is subject to the strict observance of the operating
instructions in respect of the technical spaces in the installation and
operating limits specified in this manual. The machine is designed for
outdoor installation.
DANGER!
The machine is designed for outdoor installation.
Segregate the unit if installed in areas accessible to
persons under 14 years of age.
DANGER!
Do not introduce pointed objects through the air
flow and intake grilles.
IMPORTANT!
The unit will function correctly only if the
instructions for use are scrupulously followed, if
the specified clearances are complied with during
installation, as well as the use restrictions indicated
in this manual.
IMPORTANT!
If clearance distances are not maintained at
installation, it could cause malfunctioning with an
increase in absorbed power and a considerable
reduction in cooling capacity.
DANGER!
Be careful of hot surfaces inside the machine

I.1.6 SAFETY INFORMATION
DANGER!
Always install a general automatic switch in a
protected area near the machine, which has a
characteristic delayed curve, sufficient capacity and
breaking power. There must be a minimum distance
of 3 mm between the contacts.
Earth connection is compulsory by law to ensure
user safety while the machine is in use.
DANGER!
Connections must be made in compliance with
current standards and with the diagrams provided
with the machine.
The safety door interlock automatically prevents electric power being
fed to the unit if the cover panel over the electrical panel is opened.
I.1.7 INFORMATION REGARDING UNINTENDED
USE
DANGER!
The machine was designed and built solely to
function as reversible condensing with
condensation / evaporation air; any other use other
than this is Expressly Forbidden. Installing the
machine in an explosive environment is prohibited.
