• Repair to intrinsically safe components
"Intrinsically safe components must be replaced."
• Decommissioning
Before carrying out this procedure,it is essential that the technician is completely familiar with the
equipment and all its detail.
It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried
out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered
refrigerant. It is essential that electrical power is available before the task is commenced.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically.
c) Before attempting the procedure ensure that:
- mechanical handling equipment is available, if required, for handling refrigerant cylinders
- all personal protective equipment is available and being used correctly
- the recovery process is supervised at all times by a competent person
- recovery equipment and cylinders conform to the appropriate standards.
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.

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.
Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
• Mechanical connections (mechanical connectors or flared joints) shall be accessible for maintenance
purposes.
• When mechanical connectors are reused indoors, sealing parts shall be renewed.
• When flared joints are reused indoors, the flare part shall be re-fabricated.
• This appliance incorporates an earth connection for functional purposes only.
• Flexible pipe elements shall be protected against mechanical damage, excessive stress by torsion, or
other forces. They should be checked for mechanical damage annually.
• Protection devices, piping and fittings shall be protected as far as possible against adverse
environmental effects, for example, the danger of water collecting and freezing in relief pipes or the
accumulation of dirt and debris.
• Precautions shall be taken to avoid excessive vibration or pulsation to refrigerating piping.
