1 - INTRODUCTION
The 38ZS/ZF range are air-cooled condensing units designed
for installation outdoors. They can be connected on-site with one
direct expansion exchanger (or two in case of models 200 to 360).
● 1 cooling circuit, 1 compressor:
Models: 90 / 100 / 120 / 160 / 180 / 182
● 2 cooling circuits, 2 compressors:
ModelS: 200 / 240 / 320 / 360 / 420 / 485 / 540 / 600
Two options are available:
● 38ZS series: non reversible units.
● 38ZF series: reversible units
They are equipped axial fan(s) with free vertical discharge,
hermetic scroll-type compressor(s) and electric panel with
electronic control with optimized components for the refrigerant
R-410A.
A vast number of options meet numerous operating demands.
2 - SAFETY ADVISE
To avoid any risk of accident during installation, commissioning
or maintenance, it is obligatory to take into consideration the
following specifi cations for the units: refrigerated circuits under
pressure, refrigerant presence, electrical voltage presence and
implantation place.
Because of all of this, only qualifi 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 specifi c
instructions.
Compliance with the norms and regulations in eff 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.
Caution: Before intervening in the unit, verify that the
main power to the unit is cut off . An electric shock can
cause personal damage. The main disconnect switch
is located in the unit's electric cabinet.
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
Refrigerant
Important: These units contain R-410A, a fluorinated
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,
All of the units are tested and checked in the factory.
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 certifi cations,
understand the instructions given in this manual and be familiar
with the specifi c technical characteristics of the installation site.

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".
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 specifi c for R-410A that avoids a possible mixture of
refrigerants and/or oils.
