Compliance With Regulations And Directives - Lennox eCOMFORT R32 GAC 035S Installation, Operating And Maintenance Manual

COMPLIANCE WITH REGULATIONS AND DIRECTIVES

The units comply with the directives and regulations which apply at the time of their placing on the market.
For more information, please see the product's Declaration of Conformity.
SAFETY DEVICES:
This equipment is protected with calibrated safety pressure switches.
PRESSURE RELIEF VALVES:
This equipment contains pressure relief valves to limit damage in the event of an external fire. Make sure that people are not exposed
to refrigerant discharge.
IMPORTANT NOTICE:
All work on the unit must be carried out by a qualified and authorized personnel.
Non-compliance with the following instructions may result in injury or serious accidents.
Works on the unit:
• The unit shall be isolated from the electrical supply by disconnecting and locking out the main isolating switch.
• Workers shall wear the appropriate personal protective equipment (helmet, gloves, glasses, etc.).
Works on the electrical system:
• Work on electrical components shall be performed with the power off by suitably trained and qualified personnel.
EMC DIRECTIVE COMPLIANCE - WARNING:
This equipment is compliant with the essential requirements of the EMC2014/30/EU directive for residential environment (without
eDrive pump option) and industrial environment (with eDRive pump option).
The units meet the following hardest environments standards, according to the product's Declaration of Conformity:
• EN 61000-6-2: immunity for industrial applications.
• EN 61000-6-3 without eDrive pump option: Emissions for residential, commercial and light industry applications.
• EN 61000-6-4 with eDrive pump option: Emissions for industrial environments.
• 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=0.185Ω 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 prelimi-
nary agreement of the power supply local provider.
The differences between the various machines are only related to the power of the compressors and equipment that are associated.
For conducted and radiated emission and immunity, these differences do not alter the results.
Work on the refrigerant circuits:
• 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 release of refrigerant and oil, the relevant circuit shall be drained and at zero pressure befo-
re any disassembly or unbrazing of the refrigerating parts takes place.
• To vacuum the unit with appropriate vacuum device for R32 (A2L) and to charge the unit with dry nitrogen to enable possible re-
maining R32 to be removed from oil. Repeat these operations twice.
• 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 NF EN1044.
Replacement of components:
• In order to maintain CE marking compliance, replacement of components shall be carried out using approved parts by LENNOX.
• Only the coolant shown on the manufacturer's nameplate shall be used, to the exclusion of all other products (mix of coolants,
hydrocarbons, etc.).
CAUTION:
In the event of fire, refrigerating circuits can cause an explosion and spray coolant gas and oil.
F-GAS REGULATION:
PLEASE READ THE SAFETY DATA SHEET OF THE REFRIGERANT BEFORE ANY INTERVENTION OR INSTALLATION OF THE
UNIT.
Operators of refrigeration equipment's must comply with the obligations defined in:
• Regulation on Fluorinated greenhouse gases (F Gas).
• Regulation on substances that deplete the ozone layer.
Installation manual / eCOMFORT R32-MIL166E-0222 - 09/2022
Non compliance with these requirements is an offence and liable of financial penalties.
Moreover, in case of problem it is mandatory to prove to the insurance company that the equipment
complies with the F gas Regulation.
