Before use
Extraction and evacuation
When entering the refrigerant circuit for repairs, or for any other purpose, conventional procedures
should be used. However, in the case of ammable refrigerants it is important that the procedure is the
most appropriate, as combustion is a factor to be taken into account. The following procedure should be
followed:
remove the refrigerant
purge the circuit with inert gas
evacuate
purge with inert gas
Open the circuit by cutting or welding
The refrigerant charge shall be recovered in suitable recovery cylinders. For products containing am-
mable refrigerants, the system must be purged with oxygen-free nitrogen to make the product safe for
ammable refrigerants. This process may need to be repeated several times. Compressed air and oxy-
gen should not be used to purge refrigerant systems.
For products containing ammable refrigerants, refrigerant ushing should be performed by breaking
the vacuum in the system with oxygen-free nitrogen and continuing to ll until working pressure is rea-
ched, then venting to atmosphere and nally lowering to vacuum. This process must be repeated until
there is no refrigerant in the system. When the nal charge of oxygen-free nitrogen is used, the system
must be vented to atmospheric pressure in order to perform the work. This operation is absolutely vital
for brazing operations performed on piping.
Make sure that the vacuum pump outlet is not close to any possible source of ignition and that ventila-
tion is available.
Charging procedures
In addition to conventional charging procedures, the following requirements must be followed:
Ensure that you do not contaminate yourself with different refrigerants when using the charging equi-
pment. Hoses or lines should be kept as short as possible to minimise the amount of refrigerant they
contain.
Cylinders should be kept in the proper position according to the instructions.
Ensure that the refrigeration system is grounded before charging with refrigerant.
Label the equipment when charging is complete (if not already done).
Great care must be taken not to overcharge the refrigeration system.
Note: Before relling the system, the system shall be pressure tested with the appropriate purge gas. The
system shall be leak tested at the end of charging but before commissioning. A follow-up leak test shall
be carried out before leaving the site.
