using charging equipment. Hoses or lines shall be as short as possible to
minimize the amount of refrigerant contained in them.
• Cylinders shall be kept in an appropriate position according to the instruc-
tions.
• Ensure that the refrigerating system is earthed prior to charging the sys-
tem with refrigerant.
• Label the system when charging is complete (if not already).
• Extreme care shall be taken not to over fi ll the refrigerating system.
Prior to recharging the system, it shall be pressure-tested with the appropriate
purging gas. The system shall be leak-tested on completion of charging but
prior to commissioning. A follow up leak test shall be carried out prior to leav-
ing the site.
17. Decommissioning
Before carrying out this procedure, it is essential that the technician is com-
pletely 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 sup-
ply 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 re-
frigerant cylinders.
• all personal protective equipment is available and being used correctly.
• the recovery process is always supervised 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 extraction so that refrigerant
can be removed from various parts of the system.
f) Make sure that cylinder volume is suf fi cient before recovery takes place.
g) Start the recovery machine and operate in accordance with instructions.
h) Do not over
fi ll cylinders (no more than 80 % volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even tem-
porarily.
