Recovery - Beko BP207C Manual De Usuario

2. Instructions for repairing appliances containing
R290
Equipment shall be labelled stating that it has
been de-commissioned and emptied of refri-
gerant.The label shall be dated and signed.
Ensure that there are labels on the equipment
stating the equipment contains flammable
refrigerant.

2.11 Recovery

When removing refrigerant from a system,
either for servicing or decommissioning, it is
recommended good practice that all refrigerants
are removed safely. When transferring refrigerant
into cylinders, ensure that only appropriate
refrigerant recovery cylinders are employed.
Ensure that the correct number of cylinders for
holding the total system charge are available.
All cylinders to be used are designated for the
recovered refrigerant and labelled for that
refrigerant (i.e. special cylinders for the recovery
of refrigerant). Cylinders shall be complete with
pressure relief valve and associated shut-off
valves in good working order. Empty recovery
cylinders are evacuated and, if possible, cooled
before recovery occurs.
The recovery equipment shall be in good working
order with a set of instructions concerning the
equipment that is at hand and shall be suitable
for the recovery of flammable refrigerants.In
addition,a set of calibrated weighing scales shall
be available and in good working order. Hoses
shall be complete with leak-free disconnect
couplings and in good condition. Before using the
recovery machine, check that it is in satisfactory
working order, has been properly maintained
and that any associated electrical components
are sealed to prevent ignition in the event of a
refrigerant release. Consult manufacturer if in
doubt.
The recovered refrigerant shall be returned to
the refrigerant supplier in the correct recovery
16 / EN
cylinder, and the relevant Waste Transfer Note
arranged. Do not mix refrigerants in recovery
units and especially not in cylinders.
If compressors or compressor oils are to be
removed, ensure that they have been evacuated
to an acceptable level to make certain that
flammable refrigerant does not remain within the
lubricant. The evacuation process shall be carried
out prior to returning the compressor to the
suppliers. Only electric heating to the compressor
body shall be employed to accelerate this process.
When oil is drained from a system, it shall be
carried out safely.
Competence of service
personnel
General
Special training additional to usual refrigerating
equipment repair procedures is required when
equipment with flammable refrigerants is
affected.
In many countries, this training is carried out by
national training organisations that are accredited
to teach the relevant national competency
standards that may be set in legislation.
The achieved competence should be documented
by a certificate.
Training
The training should include the substance of the
following:
Information about the explosion potential of
flammable refrigerants to show that flammables
may be dangerous when handled without care.
Information about potential ignition sources,
especially those that are not obvious, such as
lighters, light switches, vacuum cleaners, electric
