Warning - Lennox eCOMFORT R32 GAC 035S Installation, Operating And Maintenance Manual

WARNING

PED DIRECTIVE:
For units covered by the Pressure Equipment Directive (see EU Declaration of Conformity).
Caution: The high-pressure safety switches are essential elements which guarantee the system remains within the admissible
1.
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 pressure increase in case of external fire is not considered a condition of operation to the standard. However, the
designer must implement means to limit damage in the event of fire:
Our products, even equipped with LFL probes (for products loaded with fluid of category A2L) are not designed to withstand
a fire. This fire risk must be taken into account by the integrator/installer in the risk analysis of the place where our products
are installed. The installation site must implement all the necesary means in terms of fire protection and comply with the
regulations in force. The installation of means according to PED Directive for refrigeration systems in a separate room for
refrigerated machines meets the requirement of damage limitation.
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. This product has been designed to resist a C3H corrosive atmosphere according to ISO 9223.
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. All our units carry out a hydrostatic tests and leak test. (The entire circuit is checked using leak detectors). 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. All our units are delivered with refrigerant from factory. Then all the refrigerant circuit will be pressurized
8. The emissions of refrigerant via the safety relief valves must be channeled to the exterior of the machine room. The outlet
safety 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.
