8.0 MAINTENANCE BY SPECIALIST STAFF
Please observe these warnings when carrying out the following work when servicing a
dehumidifier:
8.1 CHECKING THE SURROUNDING AREA
Before starting any work on systems containing flammable refrigerants, safety tests must be carried
out to ensure that the risk of fire is kept to a minimum. When carrying out repairs to the
refrigeration system, the following precautions must be observed before carrying out work on the
system.
8.2 WORK SEQUENCE
The work shall be carried out in a controlled manner to minimise the risk of the presence of
flammable gases or other vapours while the work is being performed.
8.3 GENERAL WORK AREA
All maintenance personnel and other individuals working in the local area must be instructed in
the sequence of the tasks performed. Avoid working in confined spaces. The work area must be
cordoned off. It must be ensured that the working conditions within this area have been
safeguarded by checking flammable materials.
8.4 TESTING FOR THE PRESENCE OF REFRIGERANT
Before and during work, the area must be checked with a suitable refrigerant detector to ensure
that the technician is aware of the area's potentially flammable nature. Ensure that the leak
detection equipment used is suitable for the use of flammable refrigerants, i.e. that it does not
spark, is properly sealed and is safe to operate.
8.5 AVAILABILITY OF A FIRE EXTINGUISHER
Suitable fire extinguishers must be available if hot work is to be carried out on the cooling system
or associated parts. Provide a dry powder or CO2 fire extinguisher next to the loading area.
8.6 NO IGNITION SOURCES
Nobody carrying out work in connection with a cooling system that pipes containing or having
contained a flammable refrigerant are exposed in shall use ignition sources in such a way that they
may cause a fire or explosion hazard. All possible ignition sources, including cigarette smoke, must
be kept a sufficient distance away from the place of installation, repair, removal and disposal, with
the possibility of releasing potentially flammable refrigerant into the surrounding space. Before
carrying out the work, the area around the unit must be inspected to ensure that there is no risk
of fire or ignition. 'No smoking' signs must be put up.
