INTRODUCTION
The unit you have purchased is a complex machine. During installation, operation,
maintenance and repair, people and property can be exposed to risks caused by
certain conditions or components such as, but not limited to, refrigerant gas, oils,
moving parts, pressures, sources of heat, electrical voltage.
This manual provides information about the standard functions and procedures of
all units in the series and is an important support document for qualified personnel,
but does not replace them.
Before proceeding with the installation and start-up of the unit, careful-
ly read this manual and all of its notes marked with the following sym-
bols, which indicate the various levels of hazard or situations that are
potentially hazardous to prevent malfunctioning or physical damage to
property or personal injury:
HAZARD indicates a situation of imminent danger: if it is not observed,
it can cause death or serious injuries, it is mandatory to carefully follow the
listed measures.

IMPORTANT additional information on how to use the product
The manual contains important indications for commissioning the unit as well as
fundamental instructions in order to prevent personal injuries or damage to the
machine during its operation. Finally, to also guarantee that it will operate perfectly,
maintenance instructions are provided.
The unit must be installed by specialised technicians in compliance with current
laws in the country of installation. The unit must also be started up by authorised
and trained personnel, and all activities must be carried out in compliance with and
in observance of all the local standards and laws, and all work on the system must

must be paid when working on it, observing the precautions against
residual risks.
GENERAL WARNINGS
ATTENTION:
— The machine must be transported in compliance with the laws in force in the
country of destination, considering the characteristics of the fluids it contains
and their characterisation. Incorrect transport could cause machine damage,
which would also generate refrigerant leaks. Before the first start-up, it is neces-
sary to search for any leaks using suitable personal protective equipment;
— When the product is received, check the condition and completeness of the
supply and, if it does not match what was ordered, contact the agency that sold

gases, it is mandatory to indicate the total quantity of refrigerant contained in
the installed system. This value is indicated on the rating plate on the unit;
— This unit contains fluorinated greenhouse gases covered by the Kyoto Proto-
col. Maintenance and disposal operations must be only carried out by qualified
personnel;
— This manual is an integral part of the unit and as a result it must be stored care-
fully and must always accompany it, even if transferred to another owner or
user, or if transferred to another plant. If damaged or lost, a copy can be down-
loaded from our website www.aermec.com
— The overall fire risk assessment at the place of installation (i.e. fire load calcula-
tion) is the responsibility of the user.

signs of damage. Use a platform, or suitable scaffolding to work at higher levels;
— Remove the protections from mobile elements while the unit is running;
— Touch the moving parts, stand between them or insert pointed objects through
the grids.
— Any technical intervention or cleaning operation before having disconnected
the appliance from the mains electric power supply: by positioning the system
master switch and the main device switch at "OFF".
