SAFETY
CHILLER-IOM-2004-E
8
All units are compliant with the Pressure Equipment Directive (PED)
.
Warning:
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 wit
h 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.: 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.
