AFETY ADVICE
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 qualifi ed 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 specifi c
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
Directives 2002/96/EC and 2003/108/EC regarding electrical
and electronic equipment and the management of the resulting
waste.

Refrigerant leaks:
A periodical check must be performed for refrigerant gas leaks as
per Regulation (CE) Nº517/2014 over certain greenhouse effect
fl uoride gases. Please, consult the frequency of checks in chapter
of "Maintenance".
These units work with refrigerant gas
to a maximum service pressure of 42 bar.

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 fl ammable, when in contact with a fl ame
o hot spot it can decompose in fl uorhydric acid HF and fl uophosgene
COF which are highly 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 specifi c for R-410A that avoids a possible
mixture of refrigerants and/or oils.
