INSTALLATION AND MAINTENANCE
•
The appliance may not be installed close to combustible materials, or the air duct
inlet of an adjacent building.
•
With some appliances, it is essential to fit a "protection grid"-type accessory if the
unit is installed in an area with uncontrolled access.
•
During installation, troubleshooting 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 fitting 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 qualified brazers.
•
Replacement pipes must always be made of copper in compliance with standard
NF EN 12735-1.
•
Leak detection; pressure test:
-
never use oxygen or dry air, risk of fire or explosion,
-
use dry nitrogen or the mixture of nitrogen and refrigerant indicated on the
information 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 optional 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 certificate in compliance with standard NF EN 10204
must be requested from the supplier and filed in the installation's technical file.
•
Technical data relative to the safety requirements of the various applicable directives
must be indicated on the information plate. This data must be recorded in the
installation instructions for the appliance which are included in the installation
technical file: 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 acoustic 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.
