2 - SAFETY ADVISE
2.1 - General safety advise
Units are designed to provide a very high level of safety during
installation, start-up, operation and maintenance.
They will provide safe and reliable service when operated within
their application range.
It is required to follow the recommendations and instructions
in this brochure, the labels, and the specific instructions.
Compliance with the norms and regulations in effect 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.
To avoid any risk of accident during installation, commissioning
or maintenance, it is obligatory to take into consideration the
following specifications for the units: refrigerated circuits under
pressure, refrigerant presence, electrical voltage presence and
implantation place.
All operations on the unit must be carried out by authorized,
qualified and trained people to do it using appropriate tools.
All refrigerant charging, removal and draining operations
must be carried out by a qualified technician and with the
correct equipment for the unit. Any inappropriate handling
can lead to uncontrolled fluid or pressure leaks.
All persons who have to work with the equipment must wear
personal protective equipment adapted to the intervention on
the unit:
■Safety shoes.
■Safety gloves or specific hand protection (cut resistant gloves,
chemical gloves, thermic gloves, …).
■Head protection.
■Ears protection.
■Eyes or face protection (safety glasses, goggles, facial shed).
■A2L detector, in units with A2L gas (R-454B).
Additional equipment may be required, depending on the risk
analysis that must be done prior to any intervention.
The unit must be installed in a place that is not accessible
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.
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 electrical cabinet.
No combustible matter should be placed within 6.5
metres of the unit.
Risk of explosion: Never exceed the specified maximum
operating pressures.
Verify the allowable maximum high-side and low-side test
pressures by checking the instructions in this manual and
the pressures given on the unit name plate.
to the public or protected against access by non-authorized
persons.
Do not modify or bypass any of the safety guards or switched
in the system.
Risk of falling: No part of the unit must be used as a
walk-way, rack or support. Use a platform, or staging to
work at higher levels.
It is mandatory to use all required PPE for work at height.
Pay special attention to units with lower supply and/or
return.
Periodically check and repair or if necessary replace any
component or piping that shows signs of damage. The
refrigerant lines can break under the weight and release
refrigerant, causing personal injury.
Two configurations are available, depending on the indoor air
flow direction:
■“Standard”: all models, with R-410A and R-454B.
■“In-line”: models 052 to 093, only with R-410A.
These units are designed to be installed outdoors, in a free field-
type, well ventilated area. It is user’s responsibility to ensure that
the final installation respects all local, national and international
regulations.
The unit is connected directly to an air distribution ductwork without
additional elements or equipment, pipes, cables, etc. taking no
floor space at all. This design reduces the cost of installation,
facilitates a quick connection and ensures reliable operation.
■The units comply with European Directives:
- Machinery Directive 2006/42/EC (MD)
- Electromagnetic Compatibility Directive 2014/30/EU (EMC)
- 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)
After manufacturing, all units are charged with the selected
refrigerant: R-410A or R-454B, and are tested at the factory,
verifying the correct operation of all their components within
the operating range for which they are intended.
Technicians who install, commission, operate and service the unit
must possess the necessary training and certifications, understand
the instructions given in this manual and be familiar with the
specific technical characteristics of the installation site.
Important: These units are prepared to withstand a maximum
available pressure of 800 Pa. If there is a higher pressure,
deformation, breakage, etc., may occur.
In the case of an installation fire test, the unit can be deformed
and/or broken. It is necessary to foresee this test and to take
appropriate measures.

2 - SAFETY ADVISE
2.2 - Safety standards for refrigerant
Important: These units contain 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, known as F-Gas, over Certain greenhouse
effect fluoride gases.
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: the type of refrigerant included in the unit can be
consulted on the name plate, see section 4.3.
Type of refrigerant R-410A R-454B
Global warming potential (GWP) 2.088 466
Flammability class A1 A2L
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.
Always remember that refrigeration systems contain pressurised
liquids and vapours. All necessary provisions must be made
when the system is partially opened: ensure the part of the circuit
concerned is not pressurised.
Ensure good ventilation, as accumulation of refrigerant in an
enclosed space can displace oxygen and cause asphyxiation or
explosions.
Inhalation of high concentrations of vapour is harmful and may
cause heart irregularities, unconsciousness, or death. Vapour
is heavier than air and reduces the amount of oxygen available
for breathing. These products cause eye and skin irritation.
Decomposition products are hazardous.
Avoid contact with liquid refrigerant. Wash any spills from the
skin with soap and water. If liquid refrigerant enters the eyes,
immediately and abundantly flush the eyes with water and consult
a doctor.
The accidental releases of the refrigerant, due to small leaks
or significant discharges following the rupture of a pipe or an
unexpected release from a relief valve, can cause frostbites and
burns to personnel exposed. Do not ignore such injuries. Installers,
owners and especially service engineers for these units must:
■Seek medical attention before treating such injuries.
■Have access to a first-aid kit, especially for treating eye injuries.
Refrigerant R-410A
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 flammable, keep them away from open flames
(e.g. cigarettes) as temperatures of over 300°C cause their
vapours to break down and form phosgene, hydrogen fluoride,
hydrogen chloride and other toxic compounds. These compounds
may produce severe physiological consequences if accidentally
inhaled or swallowed.
In case of a leak:
■To detect leaks, an electronic leak detector, an ultraviolet lamp
or soapy water must be used. Flame detectors do not help.
■If a leak occurs or if the refrigerant becomes contaminated (e.g.
by a short circuit in a motor) remove the complete charge using
an specific recovery unit for R-410A.
■The refrigerant must be stored in mobile certified containers.
■Repair the leak detected and recharge the circuit with the total
refrigerant charge, as indicated on the unit name plate. Only
charge liquid refrigerant at the liquid line.
Refrigerant R-454B
According to EN 378-1, refrigerant R-454B belongs to the A2L
group, that is, non-toxic and low flammability, so it only requires
minimal precautions for a completely safe operation.
Always use tools qualified for A2L refrigerants according to EN
378 or ISO 817.
Risk of flammability: with A2L refrigerant, always use an A2L
refrigerant detector when near the unit. Default potentially
flammable zone is 0.6 metres around the unit. See section 7.2.
Never apply an open flame or live steam to a refrigerant container.
Dangerous overpressure can result.
In case of combustion of refrigerant, do not clean combustion by-
products with water, the mixture is highly corrosive.
In case of a leak:
■To detect leaks, an electronic leak detector, must be used.
■If a leak occurs or if the refrigerant becomes contaminated
(e.g. by a short circuit in a motor) remove the complete charge
using an specific recovery unit for A2L flammable refrigerants.
■The refrigerant must be stored in mobile certified containers.
In this case a special bottle shall be used, with the top painted
in red and threaded to the left (opposite direction to R-410A).
Vacuum the recovery bottle to remove the air before fi
lling it
with flammable refrigerant.
■Use a vacuum pump, dual effect and anti-spark based on DIN
8975.
■Do not mix flammable refrigerants with other types of
refrigerants in a recovery bottle. Label the recovery bottle to
show that it contains a flammable substance.
■Check that there are no hazardous or combustible objects
nearby and make sure that in case of fire the extinguisher is
nearby. The fire extinguisher must be appropriate to the system
and the refrigerant type.
■Always check that there is no refrigerant in the cooling circuit,
rinsing with nitrogen before welding, and checking that the
nitrogen flows correctly.
■Repair the leak detected and recharge the circuit with the total
refrigerant charge, as indicated on the unit name plate. Only
charge liquid refrigerant at the liquid line.

5 - HANDLING
5.1 - Discharge via forklift truck
The unit is designed to be transported safely by using a forklift
truck. The base features guide rails to accommodate the forks
of the fork-lift truck. These guide rails ensure that the centre of
gravity of the unit remains within the forks, and at the same time,
avoid the possible introduction of the truck’s fork into functional
parts that may cause damage to the unit.
Note: the module with the heat recovery wheel (BW and RW
assemblies) also includes these guides in its base frame with the
same dimensions.
The recommended length for the forks will be bigger than the unit
width (refer to the following table), so that the entire weight-bearing
structure of the unit can be supported on the forklift truck.
The standards and recommendations of the forklift truck must also
be respected with regards to the maximum load, inclination of the
fork carriage, elevation of the load for transport, and, in particular,
the maximum speed.
Discharge of stacked units
Important: this option is only available with electronic outdoor
fans (included as standard).
The fixation set factory-installed for the transport of two stacked
units ensures the safe fixation of units and the stability of units
during transport.
The discharge of the units on-site will be done via fork-lift truck
with the forks accommodated in the guide rails of the lower unit.
The units must be unstacked after discharging. The simultaneous
handling of both units is not allowed.
The 6 fixation pieces are fixed to the units using 4 M8 screws (hex.
5.2 - Discharge via crane
Important: This discharge method is not allowed in the case of
two stacked units.
It is mandatory to follow the lifting instructions given in the drawings
provided on the next page.
Approved textile slings, suitable for the dimensions and weight
of the unit, must be used. A structure with centre of
gravity adjustment must also be used to separate the
slings from the top of the unit.
Important: slings must be attached to all the marked
rigging points (grips). These points are clearly
identified by labels.
The slings hooks should be fixed on top of the grips.
All models are provided with 2 lifting grips on each beam, except
the 052 to 099 models with BA and BB assemblies that are
provided with three lifting grips per beam.
Raise and set down the unit carefully. Take care not to tilt it by
more than 15°, as this could adversely affect its operation.
Safety when lifting can only be guaranteed if all these instructions
are followed. Otherwise, there is a risk of equipment damage or
injury to personnel.

7.1 - Storage
Important: It is prohibited to store and install the machine in an
explosive atmosphere zone (ATEX).
If it is necessary to store the unit for a period of time before its
installation, the following recommendations should be followed:
■Do not remove the protective packaging and the transport
supports. The unit packed with plastic protective film should not
remain exposed to the sun for long, as prolonged exposure of
the protective film can deteriorate the unit’s paint.
■Store the unit on a flat and horizontal surface.
■It is highly recommended to store the unit in a dry place and
protected from the weather.
■Supplied accessories must be stored in a dry and clean place
for future unit assembly.
■The unit should always be stored under the following
environmental conditions:
- Minimum ambient temperature: -30°C
- Maximum ambient temperature: 50°C
- Maximum relative humidity: 95% (to avoid condensation).
7.2 - Choice of location
When choosing the location, whatever may be the selected fashion,
the following precautions have to be taken into consideration:
■It is mandatory to comply with norm EN 378-3 on Safety and
Environmental Requirements. Part 3: “In situ” installation and
protection to people.
■Important: In units with R-454B refrigerant consult the “Rooftop
A2L Installation guide” (Nb. 10714), which includes a set of
recommendations for choosing the most suitable site. It is the
customer’s responsibility to carry out the risk analysis of the
installation.
■Important: The unit performance is not guaranteed in case of
installation at an altitude of more than 1000 meters.
■It is necessary to check that the structure supports the unit’s
weigh (please consult the weight in section 7.5).
■The area where the unit will be located must be perfectly
accessible for cleaning and maintenance operations (please
consult the “Recommended service clearance” in section 7.6).
■Since the unit is designed to work outdoors, some specific
installation norms must be followed:
- The unit will be located on the roof of the premises. If it is
(1) If the condensation pressure control (standard) is disabled, the

General information on potentially flammable zone and
ignition sources (R-454B refrigerant)
The full unit, including all options & accessories that are delivered
by the manufacturer, has been qualified for the use with A2L
refrigerant.
For that purpose, the manufacturer complies with EN 378-2 §6.2.14
and defined potentially flammable zone using EN 60079-10-1 in
order to identify where ignition sources must not be present. Then
the manufacturer designed the machine in order that, if the unit
is used the way it was designed for, there is no internal ignition
source in the internal potentially flammable zone.
Thus, the only residual risk is to have an ignition source introduced
in the potentially flammable zone by the user. For that purpose,
the manufacturer decided to represent the external potentially
flammable zone where the user must not introduce ignition source.

foreseen that it will work more on heating than on cooling, it
is preferable to direct the coil towards the sun. If little work
on heating is foreseen, choose North direction.
- The chosen location must not flood and must be above the
average height the snow reaches in that region.
- Do not install the unit in a closed enclosure or in conditions
that originate air recirculation.
- Avoid placing obstacles in the air supply or return. No obstacle
may impede the air aspiration into the coils.
- Do not fix the outdoor coil side in the predominant wind
direction.
- Do not place the fresh air hood in the prevailing wind direction
to prevent water from entering.

Minimum area for indoor air distribution
(R-454B refrigerant)
The unit with refrigerant R-454B (A2L fluid) needs a minimum
surface in the room where the air supplied by its indoor circuit will
be distributed, according to EN-378-1:
Important: It is the customer’s responsibility to carry out the risk
analysis of the installation and, as a result of that analysis, to take
the necessary measures according to standard EN-378-1. Consult
the recommendations given in the “A2L rooftop installation guide”
(Nb. 10714).
Sound Level
These units are designed to work with a low acoustic level. In any
case, the following must be taken into account for the design of
the installation: the outdoor environment for acoustic radiation, the
type of building for the noise transmitted by air, the solid elements
for the transmission of vibrations.
To reduce transmission through solid surfaces to the maximum, it
is very advisable to install shock absorbers between the ground
or structure and the unit frame. If necessary, a study must be
commissioned to an acoustic technician.
Sound power level (LW)
Sound pressure level (LP)
Measurement conditions: in a clear field, measured at a distance
of 10 metres, directivity 2 and at 1,5 metres from the ground.
Note: The sound pressure level depends on the installation
conditions and, as such, it only indicated as a guide. Values
obtained according to the ISO 3744 standard.

This indication is only here to help our customer to identify the
limits of the flammability risk.
But there is no risk of explosion linked to the used of A2L refrigerant
due to the machine itself.
Note (the following information is provided by the manufacturer
exclusively for informational purposes. The application of the
following directives relies exclusively upon the user):
According to directives 2009/104/EC and 1999/92/EC, these zones
might be qualified by the user as ATEX Zone based on the user’s
own risk analysis for which the user remains solely responsible.
According to the definition of Annex I of directive 1999/92/EC,
this zone might be classified Zone 2 because it might be a place
in which an explosive atmosphere consisting of a mixture of air
with flammable substances in the form of gas is not likely to occur
in normal operation but, if it does occur, will persist for a short
period only.
In case an additional equipment is necessary (motorized valve,
pump, etc.…), it must be:
■installed out of defined potentially flammable zone;
■qualified as a non-ignition source for the fluid used.

Silent-block
7.3 - Antivibrators assembly (silent-blocks)
Although the installer is the one who must decide on a case-by-
case basis the best way to place the unit in the ultimate location,
always in observation of the handling standards that have been
described, below is a proposed assembly sequence that may
facilitate the operation, keeping in mind that the sequence
performed in the installation shall be the one most suitable to the
solution chosen for each particular case based on the existence
(or lack thereof) of brick curb, type of silent-blocks used, etc.

The screws required for the installation of the silent-blocks are
not supplied from the factory.
These screws must have an adequate quality to withstand the
stresses to which they will be subjected, and they must be adapted
to the installation site, either on a brick curb or a steel profile.
Note: If the silent-block hole has a diameter greater than M12, a
washer can be used to adjust the size.
Max. 60mm
M12

In the event of assembling directly on silent-blocks to the ground,
it is recommended that a template of the unit’s footprint with the
anchoring points of the silent-blocks be made, as described in the
paragraph “Preparation of the ground”.
With the help of the crane or the forklift truck, the unit will be raised
to a sufficient height that the silent-blocks can be screwed into its
base (see Chapter 5).
M12 metric threads have been provided
for their placement in the supports
(consult the fixing for antivibrators in
paragraph 7.5). All models will use M12
screws with a maximum length of 60 mm.
A hex key 19 or Allen wrench 10 will be
used for this operation based on the type
of screw used.
The optional silent-blocks that can be supplied for these units
must be placed perpendicular to the unit, as shown in the following
image.
Foresee appropriate damping devices in these fixings to
ensure that noise and vibration transmission is avoided
(consult the reactions in the support in paragraph 7.5).
Preparation of the ground
It is necessary to ensure that the surface where the unit is going
to be installed in completely flat. Any defect in the preparation of
the unit support surface translates into stresses on the structure,
which may result in its deformation. The unit must be perfectly
level when installed.
These units can be installed on the floor or on a brick curb or
steel profile. Based on the fixing solution defined in the installation
project, it will be necessary to plan the placement in the base of
threaded rods in the expectation that the unit supports can be fixed
later on. To do so, it is recommended that a template be made
with the heights corresponding to the fixings.
Removing forklift guards
On units with lower supply and return, the fork-lift truck guards
must be removed. This is also the case when the units are to be
connected onto a roofcurb.
These guide rails are designed to be removed from both sides of
the unit, as required. They are secured to the unit using 4 clamping
pieces with M8 screws.
Attention: a free space equal to the width of the machine is
required for revoming the rails, bigger than the “Recommended
service clearance”.
Important: the transport guards also must be removed before
installling. These guards are fixed with M4.8 self-tapping screws.

7.4 - Pre-assembly roofcurb (optional)
The “Standard” assemblies can rest on standardised pre-assembly roofcurbs with adjustable height, built in galvanised steel panelling
with polyester paint and thermal insulation.
The levelling system uses angle pieces that allow adjustments in the X and Y axes. As a result, the unit will be perfectly levelled on
a sloping roof.
These roofcurbs can also incorporate a gas burner. For more information consult the paragraph 12.14 “Gas burner”.
Note: These units have a wide range of adaptation roofcurbs that are ready for direct replacement on site of units from different
manufacturers (upon request).

Insulation and waterproof sealing
Following insulation is standard for the roof curb:
■Self-adhesive rubber gasket of 9 mm around its entire perimeter
and the crossbeams.
Important: Before installing the rooftop unit, the status of this
gasket must be checked. If it is not in good condition it should
be replaced.
When the installation of the roof curb is finished, the steel pan
must be insulated again. It is also necessary to completely seal
the roof curb to ensure tightness and prevent water from entering
the building.
Important: These works are the sole responsibility of the installer.
Caution: it is strictly forbidden to get onto the roof curb.

Important: All roof curb are supplied with a return safety grille
intended for plenum installations. For installations with ducted
return, the grille must be removed prior to place the machine on the
roof curb. This grille is fastened using 4.8 self-tapping hex screws.
The machine fits perfectly on the
roof curb, no connecting element is
necessary.
Positioning the unit above the roof curb
Once the previous work has been carried out, the rooftop unit can
be positioned above the roof curb with the help of a crane. For
the handling of the unit, the recommendations given in chapter 5
should be followed.
Suction cup handles can be used to guide this operation.
