follow the ANNEX HH requirements of UL 60335-2-40 4th Edition.
Examples for such working procedures are:
• Breaking into the refrigerating circuit;
• Opening of sealed components;
• Opening of ventilated enclosures.
7
7) Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before
breaking into the system or conducting any hot work. A degree of ventilation
shall continue during the period that the work is carried out. The ventilation
should safely disperse any released refrigerant and preferably expel it externally
into the atmosphere.
8) Checks to the refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose
and to the correct specifications. At all times the manufacturer's maintenance
and service guidelines shall be followed. If in doubt consult the manufacturer's
technical department for assistance. The following checks shall be applied to
installations using flammable refrigerants: the actual refrigerant charge is in
accordance with the room size within which the refrigerant containing parts are
installed; the ventilation machinery and outlets are operating adequately and are
not obstructed; if an indirect refrigerating circuit is being used, the secondary
circuit shall be checked for the presence of refrigerant; marking to the
equipment continues to be visible and legible.
Markings and signs that are illegible shall be corrected; and refrigerating pipe or
components are installed in a position where they are unlikely to be exposed to
any substance which may corrode refrigerant containing components, unless the
components are constructed of materials which are inherently resistant to being
corroded or are suitably protected against being so corroded.
9) Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety
checks and component inspection procedures. If a fault exists that could
compromise safety, then no electrical supply shall be connected to the circuit
until it is satisfactorily dealt with. If the fault cannot be corrected immediately
but it is necessary to continue operation, an adequate temporary solution shall
be used.
This shall be reported to the owner of the equipment so all parties are advised.
Initial safety checks shall include: That capacitors are discharged: this shall be
done in a safe manner to avoid possibility of sparking; that there no live electrical
components and wiring are exposed while charging, recovering or purging the
system; that there is continuity of earth bonding.
5) Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any
associated parts, appropriate fire extinguishing equipment shall be available to
hand. Have a dry powder or CO
2
fire extinguisher adjacent to the charging area.
6) No ignition sources
No person carrying out work in relation to a refrigerating system which involves
exposing any pipe work that contains or has contained flammable refrigerant
shall use any sources of ignition in such a manner that it may lead to the risk of
fire or explosion. All possible ignition sources, including smoking, should be kept
suciently far away from the site of installation, repairing, removing and disposal,
during which flammable refrigerant can possibly be released to the surrounding
space. Prior to work taking place, the area around the equipment is to be surveyed
to make sure that there are no flammable hazards or ignition risks. "No Smoking"
signs shall be displayed.
8
7. Sealed electrical components shall be replaced.
8. Intrinsically safe components must be replaced.
and the appropriate percentage of gas (25 % maximum) is confirmed. Leak
detection fluids are suitable for use with most refrigerants but the use of
detergents containing chlorine shall be avoided as the chlorine may react with
the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked
flames shall be removed/ extinguished. If a leakage of refrigerant is found which
requires brazing, all of the refrigerant shall 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.
When breaking into the refrigerant circuit to make repairs—or for any other
purpose - conventional procedures shall be used. However, for flammable
refrigerants it is important that best practice be followed, since flammability is
a consideration. The following procedure shall be adhered to:
-Safely remove refrigerant following local and national regulations;
-Evacuate;
-Purge the circuit with inert gas (optional for A2L);
-Evacuate (optional for A2L);
-Continuously flush or purge with inert gas when using flame to open circuit; and
-Open the circuit.
The refrigerant charge shall be recovered into the correct recovery cylinders if
venting is not allowed by local and national codes. For units containing
flammable refrigerants, the system shall be purged with oxygen-free nitrogen to
render the appliance safe for flammable refrigerants. This process may need to
be repeated several times. Do not use compressed air or oxygen to purge
refrigerant systems.
For units containing flammable refrigerants, refrigerants purging shall be
achieved by breaking the vacuum in the system with oxygen-free nitrogen and
continuing to fill until the working pressure is achieved, then venting to
atmosphere, and finally 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 final 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.
11. Removal and evacuation
Check that cabling will not be subject to wear, corrosion, excessive pressure,
vibration, sharp edges or any other adverse environmental eects. The check
shall also take into account the eects of aging or continual vibration from
sources such as compressors or fans.
9. Cabling
Under no circumstances shall potential sources of ignition be used in the
searching for or detection of refrigerant leaks. A halide torch (or any other
detector using a naked flame) shall not be used.
The following leak detection methods are deemed acceptable for systems
containing flammable refrigerants. Electronic leak detectors shall be used to
detect flammable refrigerants, but the sensitivity may not be adequate, or may
need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free
area.) Ensure that the detector is not a potential source of ignition and is suitable
for the refrigerant used. Leak detection equipment shall be set at a percentage
of the LFL of the refrigerant and shall be calibrated to the refrigerant employed
10. Detection of flammable refrigerants

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 reclaimed 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.
f) Make sure that cylinder is situated on the scales before recovery takes place.
g) Start the recovery unit and operate in accordance with manufacturer's
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 o.
k) Recovered refrigerant shall not be charged into another refrigeration system
unless it has been cleaned and checked.
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.
In addition to conventional charging procedures, the following requirements shall
be followed.
Ensure that contamination of dierent refrigerants does not occur when 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 instructions.
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 shall be taken not to overfill the refrigeration system. Prior to recharging the
system it shall be pressure tested with OFN. 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.
12. Charging procedures
13. Decommissioning
10
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.
14. Labeling
11
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. special cylinders
for the recovery of refrigerant). Cylinders shall be complete with pressure relief
valve and associated shut-o valves in good working order. Empty recovery
cylinders are evacuated and, if possible, cooled before recovery occurs. The
recovery equipment shall be in good working order with a set of instructions
concerning the equipment that is at hand and shall be suitable for the recovery of
the flammable refrigerant. If in doubt, the manufacturer should be consulted. In
addition, a set of calibrated weighing scales shall be available and in good working
order. Hoses shall be complete with leak-free disconnect couplings and in good
condition.
The recovered refrigerant shall be processed according to local legislation in the
correct recovery cylinder, and the relevant waste transfer note arranged. Do not
mix refrigerants in recovery units and especially not in cylinders. If compressors or
compressor oils are to be removed, ensure that they have been evacuated to an
acceptable level to make certain that flammable refrigerant does not remain within
the lubricant. The compressor body shall not be heated by an open flame or other
ignition sources to accelerate this process. When oil is drained from a system, it
shall be carried out safely.
