IMPORTANT SAFETY INSTRUCTIONS
10
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 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 open flames (for example an
operating gas appliance) and ignition sources (for example an operating electric heater).
Do not pierce or burn. Be aware that flammable refrigerants may not contain an odor.
The appliance shall be stored in a well-ventilated area where the room size corresponds to the room area
as specified for operation.
The appliance shall be stored so as to prevent mechanical damage from occurring.

Technical Safety

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.
