INSTALLATION AND MAINTENANCE
• The appliance may not be installed close to combusble materials, or the air duct
inlet of an adjacent building.
• With some appliances, it is essenal to t a "protecon grid"-type accessory if the
unit is installed in an area with uncontrolled access.
• During installaon, troubleshoong and maintenance, pipes may not be used as
steps: the pipe could break under the weight, spilling coolant and possibly causing
serious burns.
• Before beginning work on the cooling circuit, stop the appliance and wait for a few
minutes before ng the temperature and pressure sensors. Some elements such
as the compressor and piping may reach temperatures in excess of 100°C and high
pressures with the consequent risk of severe burns.
TROUBLESHOOTING
All brazing must be carried out by qualied brazers.
• Replacement pipes must always be made of copper in compliance with standard
NF EN 12735-1.
• Leak detecon; pressure test:
- never use oxygen or dry air, risk of re or explosion,
- use dry nitrogen or the mixture of nitrogen and refrigerant indicated on the
informaon plate,
• the test pressure for both the high and low pressure circuits must not exceed 42
bar in cases where the appliance is equipped with the oponal pressure gauge.
• The high pressure circuit pipes are made of copper and have a diameter equal to or
greater than 1’’5/8. A 2.1 test cercate in compliance with standard NF EN 10204
must be requested from the supplier and led in the installaon's technical le.
• Technical data relave to the safety requirements of the various applicable direcves
must be indicated on the informaon plate. This data must be recorded in the
installaon instrucons for the appliance which are included in the installaon
technical le: model, code, serial number, maximum and minimum OT, OP, year of
manufacture, EC label, manufacturer’s address, refrigerant and weight, electrical
parameters, thermo-dynamic and acousc performances.
LABELLING
• The equipment must be labelled so as to specify that it is out of order and that the
refrigerant has been drained.
• The label must be dated and signed.
