1 - INTRODUCTION
The
30PA
cooling only are compact outdoor air/water units.
Available in two versions:
• STD (Standard)
• HEE (High Energy E
ffi
ciency)
These units have been made for operation indoor, o
ff
ers an optimal
solution for all process cooling applications.
They are equipped with centrifugal fan (STD version) or
electronic plug-fan (HEE version), plate exchanger, hermetic
scroll compressor, and electronic control with microprocessor,
components optimised for the R-410A refrigerant.
The entire range also has the option to include a desuperheater
circuit that allows for the production of hot water at a temperature
greater than in the condensation circuits.
After manufacturing, all units are charged with refrigerant
and are tested at the factory, verifying the correct operation
of all their components within the operating range for which
they are intended.
■
The units comply with European Directives:
-Machinery Directive 2006/42/EC (MD)
-Electromagnetic Compatibility Directive 2014/30/EU (EMC)
-Low Voltage Directive 2014/35/EU (LVD)
-Pressure Equipment Directive 2014/68/EU (Category 2)
(PED)
-RoHS Directive 2011/65/EU (RoHS)
-Eco-design Directive 2009/125/EC (ECO-DESIGN)
-Energy Labelling Directive 2017/1369/EU (ECO-
LABELLING)
-Harmonised Standard: EN 378-2:2012 (Refrigerating systems
and heat pumps - Safety and environmental requirements).
Technicians who install, commission, operate and service the unit
must possess the necessary training and certi
fi
cations, understand
the instructions given in this manual and be familiar with the
speci
fi
c technical characteristics of the installation site.
2 - SAFETY ADVISE
To avoid any risk of accident during installation, commissioning
or maintenance, it is obligatory to take into consideration the
following speci
fi
cations for the units: refrigerated circuits under
pressure, refrigerant presence, electrical voltage presence and
implantation place.
Because of all of this, only quali
fi
ed and experienced personnel
can perform maintenance tasks or unit repairs.
It is required to follow the recommendations and
instructions in this brochure, the labels, and the speci
fi
c
instructions.
Compliance with the norms and regulations in e
ff
ect is
mandatory. It is recommended to consult the competent
authorities regarding the applicable regulations for
users of units or components under pressure. The
characteristics of these units or components are included
on the plates of characteristics or in the regulatory
documentation provided with the product.
In case of a leak:
■
Toxicity: According to EN 378-1, R-410A belongs to the A1/
A1 group, i.e. with high safety both in the mix and also in the
case of a leak.
■
Although it is not toxic, in case of a leak to atmospheric pressure
the liquid phase evaporates. The resulting vapours are still
hazardous because they are heavier than air and can force
the latter out of the machine rooms. If refrigerant is accidentally
released, ventilate the room with fans.
■
Although it is not
fl
ammable, keep them away from open
fl
ames (e.g. cigarettes) as temperatures of over 300°C cause
their vapours to break down and form phosgene, hydrogen
fl
uoride, hydrogen chloride and other toxic compounds. These
compounds may produce severe physiological consequences
if accidentally inhaled or swallowed.
■
To detect leaks, an electronic leak detector, an ultraviolet lamp
or soapy water must be used . Flame detectors do not help.
■
Immediately repair any refrigerant leak, using a recovery unit
speci
fi
c for R-410A that avoids a possible mixture of refrigerants
and/or oils.
The compressor and line surfaces can reach temperatures
above 100ºC causing burns to the body. In the same
fashion, under certain conditions these surfaces can
reach very cold temperatures that can cause freezing
risks.
During any handling, maintenance or service operations,
the technicians involved must be equipped with safety
gloves, glasses, shoes, insulating clothing, etc
Caution:
Before intervening in the unit, verify that the
main power to the unit is cut o
ff
. An electric shock can
cause personal damage. The main disconnect switch is
located in the unit’s electrical cabinet.

Ensure that refrigerant is never released to the atmosphere when
the equipment is installed, maintained or sent for disposal.
It is prohibited to deliberately release refrigerant into the
atmosphere. The operator must ensure that any refrigerant
recovered is recycled, regenerated or destroyed.
The operator is bound by the obligation to perform periodical
sealing tests on the refrigerating circuit according to the regulation
(EU) No.517/2014
.
Please, consult the frequency of tests in
chapter of “Maintenance”.

Important:
These units contain
R-410A
, a
fl
uorinated greenhouse
gas covered by the Kyoto protocol.
All interventions on the refrigerating circuit must be performed in
accordance with applicable legislation. Within the European Union,
it is necessary to observe regulation (EU) No.517/2014, known as
F-Gas, over
