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”.

Packaged rooftop units

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.

Packaged rooftop units

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.
