OMEGA ALTISE
IMPORTANT SAFETY INSTRUCTIONS
(d) Pump down refrigerant system, if possible.
(e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various
parts of the system.
(f) Make sure that cylinder is situated on the scales before recovery takes place.
(g) Start the recovery machine and operate in accordance with instructions.
(h) Do not overfill cylinders (no more than 80 % volume liquid charge).
(i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
(j) When the cylinders have been filled correctly and the process completed, make sure that the
cylinders and the equipment are removed from site promptly and all isolation valves on the
equipment are closed off.
(k) Recovered refrigerant shall not be charged into another refrigerating system unless it has been
cleaned and checked.
Labelling
• Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant.
The label shall be dated and signed. For appliances containing flammable refrigerants, ensure that
there are labels on the equipment stating the equipment contain flammable refrigerant.
• When removing refrigerant from a system, either for servicing or decommissioning, it is
recommended good practice that all refrigerants are removed safely.
Recovery
• 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 all appropriate refrigerants
including, when applicable, 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.
Warnings for Disposal
Refrigerant used for the air-conditioner are flammable. Therefore when the air-conditioner is scraped,
it shall be kept away from any fire source and be recovered by a special recovering company with
corresponding qualification other than be disposed by combustion, so as to prevent damage to the
environment or any other harm.
