4. SAFETY ADVICE
Natural or propane gas leaks (optional burner):
- Do not operate electric switches or other objects which could cause
sparks.
- Improve the ventilation if located in a closed area.
V-220005
V-220004
- Close the gas supply valve.
- Ensure that there is no one in the vicinity of the leak and request the
intervention of installation staff.
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.
Because of all of this, only qualified and experienced personnel can
perform maintenance tasks or unit repairs.
It is required to follow the recommendations and instructions
in the maintenance brochures, the labels, and the specific
instructions.
It is necessary to comply with the norms and regulations in
effect. 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.
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.
Use safety goggles and gloves on the job. Be careful with
sharp parts or elements in the unit.
Caution: Before intervening in the unit, verify that the main
power to the unit is cut off. An electric shock can cause
personal damage.
Note: In order to recycle these units follow the stipulations
of Directive 2012/19/EU on Waste electrical and electronic
equipment (WEEE).
These units work with refrigerant gas R-410A.
In case of a leak:
- Toxicity: According to ASHRAE 34, 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 heavier than air
and can displace the technician local air. In case of an accidental
discharge in a closed enclosure, fans must be used to eliminate said
vapours.
- Although the R-410A is not flammable, when in contact with a flame
o hot spot it can decompose in fluorhydric acid HF and fluophosgene
COF2highly toxic and corrosive.
- To detect leaks, an electronic leak detector, an ultraviolet lamp or
soapy water must be used . Flame detectors do not help.
Important: Immediately repair any refrigerant leak, using
a recovery unit specific for R-410A that avoids a possible
mixture of refrigerants and/or oils.
Refrigerant leaks:
A periodical check must be performed for refrigerant gas leaks as
per Regulation (EC) Nº517/2014 over certain greenhouse effect
fluoride gases. Please, consult the frequency of checks in chapter
of “Maintenance”.

After the placing of the unit, it is recommended to remove the grips
as well as the skids, if applicable, as they can be a hindrance for
maintenance. Put the grips back in case of unit transport. Each grip
is fixed to the crossbar using two M10 screws (hex. key 17).
Unit with condensates pan from the outdoor circuit:
With the outdoor circuit
condensates pan option, the
units include grips as the lifting
system. Check that the grips
are perfectly screwed in before
attaching the slings.
Do not raise any of the units by points outside of those
specified here. In particular, do not raise them by the
traction points of the skids.
The unit must be lifted and fixed with care and without inclination
(maximum inclination 15º), since it could harm its operation.
Note: please see the weight and the gravity centre coordinates of
each model stated in the following page.

7. TRANSPORT AND HANDLING
Transport
The unit must be handled with care to avoid transport damage. Thus
we recommend:
- Do not dispose of the pallet or the packaging materials until the unit
is in its final location.
- For transport in a container, one must be selected that has an easy
load and unload to the installation location. Optionally, the unit may
have skids that allow the units to be slid over the floor so that the
container would be easily removable. These skids make transport
pallets unnecessary.
Discharging of the unit
The unit can be discharged using a crane with a rocker arm and cloth
slings by using a forklift truck if it is done on the side of the transport
box. If the unit has transport skids at the same height of the transport
box, the unit can be discharged simply by pulling on the skids at the
points set out for them.
When using any of the three above methods, it is always mandatory
to grasp the unit by the points intended for that purpose, as described
in this chapter.
Any handling of the unit by other means or by gripping points different
from those described here may be dangerous for both the unit and
the personnel who are carrying out the discharging or transport work.
Always check the weight of the set and verify that the
discharging method used is approved for handling that weight.
- Discharge via forklift truck:
The unit is designed to be transported safely by using a forklift truck.
The forks of the forklift truck must come in on the side of the unit,
ensuring that the centre of gravity of the unit remains within the forks,
because a misbalance in the transport may cause the unit to turn
over and fall from the forklift truck.
Note: please see the weight and the gravity centre coordinates of
each model stated in the following page.
The recommended length for the forks will be bigger than the unit
width, so that the entire weight-bearing structure of the unit can
be supported on the forklift truck. This also prevents the possible
introduction of the truck’s fork into functional parts of the unit that
may cause damage to the unit.
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.
Make sure that the unit is
protected from contact with the
hooks to prevent damage to
the housing.
- Discharge via crane:
A rocker arm, as well as approved cloth slings, both suitable for the
dimensions and weight of the unit, must be used in order to carry
out the work safely and without causing damage to the units or to
workers.
These slings will be hooked to
the two mounting holes located
on each crossbar.
- Discharging to the same plane using skids (optional):
This method will be used only when it is possible to place the
transport box (trailer, maritime container, etc.) at the same height
as the discharging platform (for example, a dock).
Once the unit is discharged, it must be freed from the skids so that
the inserts available for the silent-blocks can be accessed. Each
skid is fixed to the crossbar using four M10 screws (hex. key 17).
To do so, each skid
will be gripped by the
points indicated in the
image so that it can be
pulled from the unit to be
extracted from the box.

Regulation
system
Important: All of the necessary information for the installation of these
roofcurbs is available in the specific instruction brochure on roofcurbs,
(supplied with the roofcurb).
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 UNE-EN 378-3 on Safety
and Environmental Requirements. Part 3: “In situ” installation and
protection to people.
- It is necessary to check that the structure supports the unit’s weigh
(please see the weight in the table in the “Weight summary” section).
- The area where the unit will be located must be perfectly accessible
for cleaning and maintenance operations (check minimum free space
for maintenance). Leave enough space for air circulation around the
unit.
8. LOCATION AND ASSEMBLING
- 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 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.
• 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 install the unit in a closed enclosure or in conditions that
originate air recirculation.
• The chosen location must not flood and must be above the average
height the snow reaches in that region.
Foresee appropriate damping devices in these fixings to
ensure that noise and vibration transmission is avoided (refer
to the section “Anchorage for antivibrators”).
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 frames, type of
silent-blocks used, etc.
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.
These units can be installed on the floor or on a brick frame 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.
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 previous section.
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.
The 4 silent-blocks of the corners must remain oblique and the interiors
perpendicular to the unit.
M12 metric threads have been provided for their placement in the
supports indicated in the following section “Anchorage for antivibrators”.
A hex key 19 or Allen wrench 10 will be used for this operation based
on the type of screw used.
This image shows how the
silent-block option that can
be supplied for this unit is
fixed to the unit.
Preassembly roofcurb (optional)
Optionally, standardised pre-assembly roofcurb made of galvanised
steel panelling with polyester paint and thermally insulated with
adjustable heights can be supplied.
