INFORMATION ON SERVICING
1. Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS,
safety checks are necessary to ensure that the risk of ignition is mini-
mised.
2. Work shall be undertaken under a controlled procedure so as to mini-
mise the risk of a flammable gas or vapour being present while the work is
being performed.
3. 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.
4. The area shall be checked with an appropriate refrigerant detector prior
to and during work, to ensure the technician is aware of potentially toxic
or flammable atmospheres. Ensure that the leak detection equipment
being used is suitable for use with all applicable refrigerants, i.e., nonspar-
king, adequately sealed, or intrinsically safe.
5. When performing hot work on refrigeration equipment or any related
parts, appropriate fire extinguishing equipment should be available. Dry
powder fire extinguisher or carbon dioxide fire extinguisher should be
placed near the charging area.
6. No person carrying out work in relation to a REFRIGERATING SYSTEM
which involves exposing any pipe work 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, removal and disposal,
during which refrigerant can possibly be released to the surrounding
space. Prior to work taking place, the area around the equipment shall be
surveyed to make sure that there are no flammable hazards or ignition
risks. "No Smoking" signs shall be displayed.
7. 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.
10
The ventilation should safely disperse any released refrigerant and
preferably expel it externally into the atmosphere.
8. Where electrical components are being changed, they shall be fit for
the purpose and to the correct specification. At all times, the manufactur-
er'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:
a)the actual REFRIGERANT CHARGE 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)marking to the equipment continues to be visible and legible. Markings
and signs that are illegible shall be corrected.
d)components, unless the components are constructed of materials
which are inherently resistant to being corroded or are suitably protected
against being so corroded.
9. Repair and maintenance of 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 correct-
ed 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 possibility of sparking;
b) that no live electrical components and wiring are exposed while
charging, recovering or purging the system;
c) that there is continuity of earth bonding.
Repairs to sealed
1.During repairs to sealed components, all electrical supplies shall be
disconnected from the equipment being worked upon prior to any remov-
al of sealed covers, etc. If it is absolutely necessary to have an electrical
supply to equipment during servicing, then a permanently operating form
11
of leak detection shall be located at the most critical point to warn of a
potentially hazardous situation.
2.Particular attention shall be paid to the following to ensure that by
working on electrical components, the casing is not altered in such a way
that the level of protection is affected. This shall include damage to
cables, excessive number of connections, terminals not made to original
specification, damage to seals, incorrect fitting of glands, etc.
Ensure that the apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded to the point that
they no longer serve the purpose of preventing the ingress of flammable
atmospheres. Replacement parts shall be in accordance with the manu-
facturer's specifications.
Repair to intrinsically safe components
1.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.
2.Intrinsically safe components are the only types that can be worked on
while living in the presence of a flammable atmosphere. The test appara-
tus shall be at the correct rating.
3.Replace components only with parts specified by the manufacturer.
Other parts can result in the ignition of refrigerant in the atmosphere from
a leak.
NOTE : The use of silicon sealant can inhibit the effectiveness of some
types of leak detection equipment. Intrinsically safe components do not
have to be isolated prior to working on them.
Cabling
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.
Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the
search for or detection of refrigerant leaks. A halide torch (or any other
detector using a naked flame) shall not be used.
1.Electronic leak detectors may be used to detect refrigerant leaks but, in
the case of FLAMMABLE REFRIGERANTS, the sensitivity might not be ade-
quate, or might need recalibration. (Detection equipment shall be
calibrated in a refrigerant-free area.) Ensure that the detector is not a
potential source of
12
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.
2.Leak detection fluids are applicable.
NOTE: Examples of leak detection fluids are
-bubble method,
-fluorescent method agents.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leak of refrigerant is found which requires brazing, all of the refrigerant
shall be refrigerants from the system, or isolated (by means of shut off
valves) in a part of the system remote from the leak.
Removal and evacuation
When entering the refrigerant circuit for servicing or for any other purpose,
the following procedures should be followed for combustible refrigerants:
a) safely remove refrigerant following local and national regulations;
b) purge the circuit with inert gas;
c) open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery
cylinders if venting is not allowed by local and national codes. For appli-
ances containing flammable refrigerants, the system shall be purged with
oxygen-free nitrogen to render the appliance safe for flammable refriger-
ants. This process might need to be repeated several times. Compressed
air or oxygen shall not be used for purging refrigerant systems.
For appliances 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. When the final oxygen-free nitrogen charge is
used, the system shall be vented down to atmospheric pressure to enable
work to take place.
Ensure that the outlet for the vacuum pump is not close to any potential
ignition sources and that ventilation is available.
Charging procedures
In addition to conventional charging procedures, the following require-
ments shall be followed.
a) 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.
b) Cylinders shall be kept in an appropriate position according to the
instructions.
13
c) Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the
system with refrigerant.
d) Label the system when charging is complete (if not already).
e) Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM.
Prior to recharging the system, it shall be pressure-tested with the appro-
priate 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.
Decommissioning
Before carrying out this procedure, it is essential that the technician is
completely familiar with the equipment and all its details. It is recom-
mended 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 to the re-use of recovered refrigerant. It
is essential that electrical power is available before the task is com-
menced.
a) Become familiar with the equipment and its operation.
b) Isolate the system electrically.
c) Before attempting the procedure, ensure that:
i) mechanical handling equipment is available, if required, for handling
refrigerant cylinders;
ii) all personal protective equipment is available and being used correct-
ly;
iii) the recovery process is supervised at all times by a competent person;
iv) recovery equipment and cylinders conform to the appropriate stan-
dards.
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 machine and operate in accordance with instruc-
tions.
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 complet-
ed, 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 REFRIGERATING
SYSTEM unless it has been cleaned and checked.
14
Labelling
Equipment shall be labelled stating that it has been de-commissioned
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.
Recovery
When removing refrigerant from a system, either for servicing or decom-
missioning, 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 cylin-
ders 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 all appropriate refrigerants including, when
applicable, 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 electrical
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 evacuated to an acceptable level to make certain that FLAM-
MABLE 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
employed to accelerate this process. When oil is drained from a system, it
shall be carried out safely.
