INFORMATION ON SERVICING
Checks to the area
Prior to beginning work on systems containing flammable
refrigerants, safety checks are necessary to ensure that the
risk of ignition is minimised. For repair to the refrigerating
system, following precautions shall be completed 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 toxic or flammable atmospheres. Ensure
that the leak detection equipment being used is suitable for use
with all applicable 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

10
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 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, removing and disposal, during
which 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
department for assistance.
The following checks shall be applied to installations using
flammable refrigerants:

11
–the charge size 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;
–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:
•that capacitors are discharged: this shall be done in a safe
manner to avoid possibility of sparking;
•that no live electrical components and wiring are exposed
while charging, recovering or purging the system;
•that there is continuity of earth bonding.
Repairs to sealed components

12
1 During repairs to sealed components, all electrical supplies
shall be disconnected from the equipment being worked upon
prior to any removal of sealed covers, etc. If it is absolutely
necessary to have an electrical supply to equipment during
servicing, then a permanently operating form 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 manufacturer’s specifications.
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.
Repair to intrinsically safe components
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.

13
Replace components only with parts specified by the
manufacturer. Other parts may result in the ignition of
refrigerant in the atmosphere from a leak.
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 searching for or detection of refrigerant leaks. A
halide torch (or any other detector using a naked flame) shall
not be used.
Leak detection methods
The following leak detection methods are deemed acceptable
for all refrigerant systems.
Electronic leak detectors may be used to detect refrigerant
leaks but, in the case of flammable refrigerants, 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.

14
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 off valves) in a part of the system remote
from the leak. For appliances containing flammable
refrigerants, oxygen free nitrogen (OFN) shall then be purged
through the system both before and during the brazing
process.
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 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. For appliances containing flammable
refrigerants, 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 purging
refrigerant systems.

15
For appliances containing flammable refrigerants, 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 operation 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 that ventilation is available.
Charging procedures
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 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
the appropriate 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

16
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 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 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

17
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.
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
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 are 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 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

18
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 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 employed to accelerate this
process. When oil is drained from a system, it shall be carried
out safely.
