FLAMMABLE GASES
Please do not approach the container or truck in the presence of an open flame, an electric power source, a cell phone, or any other
heat source whose temperature would exceed 500°C.
Likewise, if the product had to be stored prior to installation, please store it in a place free from potential sources of ignition as descri-
bed above.
Persons working on refrigeration systems using flammable fluids must have the necessary skills in accordance with standard for the
safe handling of these flammable fluids.
•
Knowledge of the legislation, regulations and standards concerning flammable refrigerants.
•
Knowledge of fluids and their handling.
These skills must be supported by appropriate training.
Only equipment designed for use with flammable refrigerants should be used and all work performed on the equipment should be in
accordance with local regulations and standards. Of course, all work must be carried out in a professional manner.
To ensure the absence of a secondary ATEX zone, maintainers should:
•
Set up a periodic leakage inspection plan to ensure that the product’s leakage level is maintained.
•
Set up an inspection and maintenance plan to avoid deterioration of the product that could lead to an accidental leak during the life
of the equipment.
Corrosion: Do not use detergents. Do not use in an atmosphere corrosive to copper and aluminum without protecting the sen
sitive elements of the exchanger.
Freezing of the heat exchanger coil: Check regularly that the coil is not frozen. Check that the defrosting system is working
properly and that it is effective.
Abnormal vibrations: Check that the pipes are properly maintained.
•
If a safety chain is installed, please maintain the detection system and the associated control chain according to standards.
It is forbidden to store and install the machine in an ATEX area.
In the immediate area of the unit (proximity distance ≤ to 2m):
•
The presence, even temporary, of ignition sources is prohibited (electrical or heat sources),
•
It is forbidden to install fresh air vents in the building or in extracts
For ducting / ducted units, ensure that no sources of ignition as defined in the standards (e.g. electrical and heat) are installed in or
near the ducts.
RECEPTION CONTROLS FOR A FLAMMABLE GAS UNIT:
SAFETY:
SAFETY AREA:
INSTALLATION ON A FLAMMABLE GAS UNIT:
Our products (Rooftops, Chillers) and quasi-machines (evaporators, air-cooled condensers, ...) are hermetically sealed and carry the
CE mark. They are designed to contain slightly flammable A2L refrigerants. As such they are not considered as a source of release as
defined by the directive in normal operation. In France, they are exempt from the measures described in the regulation governing the
safety of buildings open to the public (ERP).
A formalized periodic inspection of the product’s hermeticity will guarantee the preservation of this high level of hermeticity.
Nevertheless, in abnormal operating conditions, leaks may occur (poor maintenance, maintenance with opening of the refrigeration
circuit). For these cases, prior to placing these products on the market, we carried out studies in accordance with standards. Thus the
unit installed according to our recommendations and well maintained does not generate an ATEX zone.
Please maintain the detection system and the associated control chain according to standards. In case of maintenance we recommend
that the operators be equipped with an explosimeter, switch off the power supply to the unit and do not approach any potential source
of ignition without first checking the absence of a potentially flammable area due to an undetected leak.
The end user should update the DUER (Document Unique d’Evaluation des Risques) indicating the presence on his site of products
charged with R32 fluid, and train his personnel on the good practices to be adopted for a safe use.
