• During the maintenance phase make sure there are no traces of corrosion or oil stains around the refrigerating
components.
• Before any operations on the refrigerating circuit it is imperative to shut down the appliance and to wait a few minutes
before fitting temperature or pressure sensors. Some equipment such as the compressor and piping can reach
temperatures in excess of 100°C and high pressures which can cause serious burns.
4.2.2 Repairs
• All welding operations are to be carried out by qualified welders
• Piping can only be replaced using copper tube in compliance with NF EN 12735-1 standard.
• Leak detection, pressure test:
- never use oxygen or dry air, there is a risk of fire and explosion,
- use dehydrated nitrogen or a mixture of nitrogen and the coolant indicated on the identification plate,
- the test pressure on the low and high pressure sides must not exceed 42 bar.
• For the high pressure circuit piping using copper pipes of a diameter = or > than 1''5/8, a §2.1 certificate under standard
NF EN 10204 is to be requested from the supplier and kept with the installation technical documents.
• The technical information relative to the safety requirements for the different applicable directives is indicated on
the identification plate. All this information must be recorded on the appliance installation manual which must be
part of the installation technical file: model, code, serial number, maximum and minimum service voltage and service
pressure, year of manufacture, CE marking, manufacturer's address, coolant type and weight, electric parameters,
thermodynamic and acoustic performances.

4.3 Recycling

This symbol means that your appliance must not be disposed of as household waste. It will be subject to selective
waste sorting with a view to its reuse, recycling or sale. If it contains substances that are potentially harmful to the
environment, they will be eliminated or neutralised.
Ask your reseller for information about recycling.
