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 is
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 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.
WARNING!
• 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 the refrigerants may not
contain an odour.
• Appliance should be installed,
operated and stored in a room with
a floor area larger than 12 m
• The appliance shall be stored so as
to prevent mechanical damage from
occurring a warning that the appliance
shall be stored in a well-ventilated
area where the room size corresponds
to the room area as specified for
operation.
• Any person who is involved with
working on or breaking into a
refrigerant circuit should hold a
current valid certificate from an
industry-accredited assessment
authority, which authorises their
competence to handle refrigerants
safely in accordance with an industry
recognised assessment specification.
• Servicing shall only be performed
as recommended by the equipment
manufacturer. Maintenance and repair
requiring the assistance of other
skilled personnel shall be carried out
under the supervision of the person
competent in the use of flammable
refrigerants.
