are necessary to ensure that the risk of ignition is minimised. For repair to the refriger-
ating system, the following precautions shall be complied with prior to conducting
work on the system.
Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of
a flammable gas or vapour being present while the work is being performed.
General work area
All maintenance staff and others working in the local area shall be instructed on the
nature of work being carried out. Work in confined spaces shall be avoided. The area
around the workspace shall be sectioned off. Ensure that the conditions within the
area have been made safe by control of flammable material.
Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during
work, to ensure the technician is aware of potentially flammable atmospheres.
Ensure that the leak detection equipment being used is suitable for use with flamma-
ble refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

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 CO2 fire extinguisher adjacent to the charging area.
No ignition sources
No person carrying out work in relation to a refrigeration system which involves expo-
sing 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 cigarette smoking, should be kept sufficiently
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.
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.
Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and
to the correct specification. At all times the manufacturer's maintenance and service
guidelines shall be followed. If in doubt consult the manufacturer's technical depart-
ment for assistance. The following checks shall be applied to installations using flam-
mable refrigerants:
a. The charge size is in accordance with the room size within which the refrigerant
containing parts are installed;
b. The ventilation machinery and outlets are operating adequately and are not obstructed;
c. 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;
d. Refrigeration 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.
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:
a. That capacitors are discharged: this shall be done in a safe manner to avoid possi-
bility of sparking;
Your home in sync
07

b. That there no live electrical components and wiring are exposed while charging,
recovering or purging the system;
c. That there is continuity of earth bonding.
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring
that this will not exceed the permissible voltage and current permitted for the equipment
in use. Intrinsically safe components are the only types that can be worked on while live
in the presence of a flammable atmosphere. The test apparatus shall be at the correct
rating. Replace components only with parts specified by the manufacturer. Other parts
may result in the ignition of refrigerant in the atmosphere from a leak.
Repair to intrinsically safe components
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration,
sharp edges or any other adverse environmental effects. The check shall also take into
account the effects of aging or continual vibration from sources such as compressors
or fans.
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.
Detection of flammable refrigerants
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 and the appropriate percentage of gas
(25% maximum) is confirmed. Leak detection fluids are suitable for use with most refri-
gerants 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 off valves) in a part of the system remote from the leak. Oxygen free
nitrogen (OFN) shall then be purged through the system both before and during the
brazing process.
Leak detection methods

When breaking into the refrigerant circuit to make repairs or for any other purpose
conventional procedures shall be used. However, it is important that best practice is
followed since flammability is a consideration. The following procedure shall be adhered
to:
Remove refrigerant; Purge the circuit with inert gas; Evacuate; Purge again with inert gas;
Open the circuit by cutting or brazing. The refrigerant charge shall be recovered into
the correct recovery cylinders. The system shall be flushed with OFN to render the unit
safe. This process may need to be repeated several times. Compressed air or oxygen
shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the
system with OFN and continuing to fill until the working pressure is achieved, then venting
to atmosphere, and finally pulling down to a vacuum. This process shall be repeated
until no refrigerant is within the system. When the final OFN charge is used, the system
shall be vented down to atmospheric pressure to enable work to take place. This opera-
tion is absolutely vital if brazing operations on the pipe-work are to take place. Ensure
that the outlet for the vacuum pump is not close to any ignition sources and there is
ventilation available.
Removal and evacuation
In addition to conventional charging procedures, the following requirements shall be
followed. 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 upright. Ensure that the refriger-
ation 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 commis-
sioning. A follow up leak test shall be carried out prior to leaving the site.
Charging procedures
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 refriger-
ants 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 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.
Decommissioning
Your home in sync
09

d. 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 machine 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 off.
k. Recovered refrigerant shall not be charged into another refrigeration system unless
it has been cleaned and checked.
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.
Labelling
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-off 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 flammable refrigerants. 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. Before using the recovery machine, check that it is in
satisfactory working order, has been properly maintained and that any associated elec-
trical components are sealed to prevent ignition in the event of a refrigerant release.
Consult manufacturer if in doubt. The recovered refrigerant shall be returned to the
refrigerant supplier 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 evac-
uated to an acceptable level to make certain that flammable refrigerant does not remain
within the lubricant. The evacuation process shall be carried out prior to returning the
compressor to the suppliers. Only electric heating to the compressor body shall be emp-
loyed to accelerate this process. When oil is drained from a system, it shall be carried
out safely
