Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses
-
or lines shall be as short as possible to minimise the amount of refrigerant contained in them.
Cylinders shall be kept in an appropriate position according to the instructions.
-
Ensure that the refrigerating system is earthed prior to charging the system with refrigerant.
-
Label the system when charging is complete (if not already).
-
Extreme care shall be taken not to overfill 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 leaving the site.
Dismantling
• 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.
Become familiar with the equipment and its operation.
1.
Isolate system electrically.
2.
Before attempting the procedure, ensure that:
3.
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.
-
Pump down refrigerant system, if possible.
4.
If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the
5.
system
Make sure that cylinder is situated on the scales before recovery takes place.
6.
Start the recovery machine and operate in accordance with instructions.
7.
Do not overfill cylinders (no more than 80 % volume liquid charge).
8.
Do not exceed the maximum working pressure of the cylinder, even temporarily.
9.
When the cylinders have been filled correctly and the process completed, make sure that the cylinders and
10.
the equipment are removed from site promptly and alt isolation valves on the equipment are closed off.
Recovered refrigerant shall not be charged into another refrigerating system unless it has been cleaned
11.
and checked.
LABELLING
• Equipment shall be labelled stating that it has been decommissioned 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 contains flammable refrigerant.
RECOVERING
• 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.
