IMPORTANT SAFETY INSTRUCTION
(Continued)
If a leak is suspected, all naked ames should be
removed/ extinguished. If a leakage of refrigerant is
found which requires brazing, all of the refrigerant
should be recovered from the system, or isolated
(by means of shut o valves) in a part of the system
remote from the leak. Removal of refrigerant shall
be according to Removal and evacuation..
REMOVAL AND EVACUATION
When breaking into the refrigerant circuit to make
repairs—or for any other purpose - conventional
procedures shall be used. However, for ammable
refrigerants it is important that best practice is
followed since ammability is a consideration.
The following procedure shall be adhered to:
Remove refrigerant
Safely remove refrigerant following local
and national regulations;
Evacuate;
Purge the circuit with inert gas
(optional for A2L);
Evacuate (optional for A2L);
continuously ush or purge with inert gas
when using ame to open circuit; and
open the circuit.
The refrigerant charge should be recovered
into the correct recovery cylinders. if venting
is not allowed by local and national codes. For
appliances containing ammable refrigerants,
the system shall be purged with oxygen-free
nitrogen to render the appliance safe for
ammable refrigerants. This process might need
to be repeated several times. Compressed air or
oxygen shall not be used for purging refrigerant
systems.
For appliances containing ammable
refrigerants, refrigerants purging shall be
achieved by breaking the vacuum in the system
with oxygen-free nitrogen and continuing to
ll until the working pressure is achieved, then
venting to atmosphere, and nally pulling down
to a vacuum (optional for A2L).
This process shall be repeated until no
refrigerant is within the system (optional for A2L).
When the nal oxygen-free nitrogen charge
is used, the system shall be vented down to
atmospheric pressure to enable work to take
place. The outlet for the vacuum pump shall not
be close to any potential ignition sources, and
ventilation shall be available.
CHARGING PROCEDURES
In addition to conventional charging procedures,
the following requirements should be followed.
Ensure that contamination of dierent
refrigerants does not occur when using
charging equipment.
Hoses or lines should be as short as possible
to minimize the amount of refrigerant
contained in them.
Cylinders should be kept upright.
Ensure that the refrigeration system is
earthed prior to charging the system with
refrigerant.
Label the system when charging is complete
(if not already).
Extreme care should be taken not to overll
the refrigeration system.
Prior to recharging the system, it should be
pressure tested with OFN.
The system should be leak tested on
completion of charging but prior to
commissioning.
A follow up leak test should be carried out
prior to leaving the site.
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 should be taken in case
analysis is required prior to re-use of reclaimed
refrigerant. It is essential that electrical power is
available before the task is commenced.
Become familiar with the equipment and its
operation.
WARNING
For using R32 refrigerant
