1. Attention: The high-pressure safety switches are essential elements which guarantee the system remains within the
admissible operating limits. Before switching on the installation, always ensure all electrical connections are correct on these
elements which are used to isolate the electrical power supply to the compressor(s) they protect. Carry out a test to ensure
the electrical power supply is effectively isolated when the pressure switch attains its set value.
2. In case of installation in a seismic zone or in a zone which may be effected by violent natural occurrences such as storms,
tornados, floods, tidal waves, etc…, the installer and/or operator will refer to valid standards and regulations in order to ensure
the devices required are available as our units are not designed to operate under such conditions without prior precautions.
3. The equipment is not designed to resist fire. The installation site will therefore have to respect valid standards with regard to
protection against fire (emergency instructions, map…).
4. In case of exposure to corrosive external atmospheres or products, the installer and/or operator shall take the necessary
precautions to avoid damage to the equipment and will make sure the equipment provided has the necessary and sufficient
anti-corrosion protection.
5. To respect a sufficient number of supports for the piping according to their size and weight under operating conditions and to
design the piping to avoid a water hammer phenomenon
6. For technical reasons, it is not possible to carry out hydrostatic tests on all our units so leak tests are carried out as a
compensatory measure. (The entire circuit is checked using leak detectors). For machines charged with refrigerant, at the end
of the test, an HP test is carried out in the factory to make sure the pressure switch is working properly.
7. Before any work is carried out on the refrigeration circuit, the dry air or nitrogen pressure our units are supplied with must be
released (For units not charged with refrigerant in the factory.)
8. The emissions of refrigerant via the safety relief valves must be channeled to the exterior of the machine room. The outlet
relief valve will have to be sized in compliance with EN13136.
9. Installation and maintenance of these machines must be carried out by personnel qualified to work on refrigeration equipment.
10. All interventions must be carried out in conformity with valid safety regulations (e. g.: NF EN 378), as well as the recommendations
indicated on the labels and handbooks provided with the machine. All actions shall be taken to avoid access of unauthorized
persons.
11. It is essential that any pipework or other components of the refrigeration circuit hazardous to people because of their surface
temperature are insulated or identified.
12. Ensure that the installation zone (room or area) of the machine has restricted access and ensure the good condition of the
covering.
13. The risk of inadvertent discharge is minimized.

1.2 - Warning labels
The chiller is marked with the following warning labels to alert to potential hazards (on or near the potentially hazardous part).
Regularly check that the warning labels are still in the correct positions on the machine and replace them if necessary.
