EMC DIRECTIVE COMPLIANCE
WARNING:
This equipment is an “A class» according EMC Directive. In an industrial environment, this device can create radio electrical noise. In this
case, the owner can be asked to take appropriated actions.
Neosys units comply with the following environmental standards:
• EN 61000-6-4 : Emissions for industrial environments
• EN 61000-6-2 : Immunity for industrial environments
Neosys units comply with the following most stringent environmental standards if EMC filter class B option or MS machine (without inverter):
• EN 61000-6-3: Emissions for residential, commercial and light industrial environments.
• EN 61000-6-2: Immunity for industrial environments
This applies to all machine installed with nominal amps below <75A:
• The short-circuit rate Rsce=33 is defined in the EN61000-3-12 standard relative to the harmonics readings on the supply network.
The appliances compliant with the harmonic current limits equivalent to Rsce=33 can be connected in whatever connection point of
the main supply system.
• The maximal allowable impedance of the main supply system Zmax=0.051Ω is defined by EN 61000-3-11 standard relative to the
voltage variation, fluctuation and flicker readings. The connection to the supply is a conditional connection submitted to the
preliminary agreement of the power supply local provider.
The differences between the different machines are related to the power of the compressors and the equipment associated with them. For
conducted and radiated emission, as well as for immunity, these differences are not such as to modify the results obtained.
Work on the refrigerating circuit(s):
•
Monitoring of the pressures, draining and filling of the system under pressure shall be carried out using connections
provided for this purpose and suitable equipment.
•
To prevent the risk of explosion due to spraying of coolant and oil, the relevant circuit shall be drained and at zero
pressure before any disassembly or unbrazing of the refrigerating parts takes place.
•
There is a residual risk of pressure build-up by degassing the oil or by heating the exchangers after the circuit has been
drained. Zero pressure shall be maintained by venting the drain connection to the atmosphere on the low pressure side.
•
The brazing shall be carried out by a qualified brazer. The brazing shall comply with the standard EN1044 (Minimum 30% silver).
Replacing components:
•
In order to maintain CE marking compliance, replacement of components shall be carried out using spare parts, or using parts
approved by LENNOX.
•
Only the coolant shown on the
manufacturer’s nameplate shall be used.
CAUTION:
In the event of fire, refrigerating circuits can cause an explosion and spray coolant gas and oil.

LIFETIME OF THE EQUIPMENT
The refrigerating system is designed for a lifetime of at least 10 years if the safety and maintenance instructions are strictly respected.
The lifetime of the equipment may be renewed if the periodic requalification certificate is validated by the expert (authorized body or DREAL
in France (Directions Régionales de l'Environnement, de l'Aménagement et du Logement)
8.
DISPOSAL OF THE EQUIPMENT
Equipment shut-down and recuperation of oil and coolant must be carried out by qualified personnel conform to the recommendations of
standard NF EN 378.
All elements in the refrigeration system such as refrigerant, oil, coolant, filters, dryers and insulating materials must be recuperated, re-
used and/or disposed of in a correct manner (see NF EN 378 part 4). No materials may be discarded into the environment.
