•
The device must be stored in a ventilated place away from all sources of fire.
• Install the unit outdoors. Do not install the unit indoors or in an enclosed, non-
ventilated area outdoors.
•
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
•
The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater).
• Do not pierce or burn.
• Be aware that R32 refrigerants may not contain an odour.
INSTALLATION AND MAINTENANCE
•
The appliance may not be installed close to combustible materials, or an air duct
inlet of an adjacent building.
•
With some appliances, it is essential to fit protection grids 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.
•
When servicing the appliance, the composition and state of the heat transfer fluid
must be checked, as well as the absence of any traces of coolant.
•
During the appliance’s annual sealing test in accordance with applicable legislation,
the high and low pressure switches must be checked to ensure that they are
securely fastened to the cooling circuit and that they cut off the electrical circuit
when tripped.
•
During maintenance work, ensure there are no traces of corrosion or oil around
the cooling components.
•
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.
Area check
•
Prior to beginning work on systems containing flammable refrigerants, safety
checks are necessary to ensure that the risk of ignition is minimised.
Work procedure
•
Work shall be undertaken under a controlled procedure so as to minimise the risk
of a flammable gas or vapour being present while the work is being performed.
General work area
•
AIl maintenance staff and others working in the local area shall be instructed on
the nature of work being carried out. Work in confined spaces shall be avoided.
Check for the presence of refrigerant
•
The area shall be checked with an appropriate refrigerant detector prior to and
during work, to ensure the technician is aware of potentially toxic or flammable
atmospheres. Ensure that the leak detection equipment being used is suitable
for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or
intrinsically safe.
Check for the presence of a fire extinguisher
•
If any work involving heat is to be conducted on the refrigerating equipment or
any associated parts, appropriate fire extinguishing equipment shall be available
to hand. Have a dry powder or CO
2
, fire extinguisher adjacent to the charging area.
No source of ignition
•
No person carrying out work in relation to a refrigerating system which involves
exposing any pipe work shall use any sources of ignition in such a manner that it may
lead to the risk of fire or explosion. All possible ignition sources, including cigarette
smoking, should be kept sufficiently far away from the site of installation, repairing,
removing and disposal, during which refrigerant can possibly be released to the
surrounding space. Prior to work taking place, the area around the equipment is
to be surveyed to make sure that there are no flammable hazards or ignition risks.
«No Smoking» signs shall be displayed.
