General instructions
1.1 Checks to thearea
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,
the following precautions shall be complied with prior to
conducting work on the system.
1.2 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.
1.3 General workarea
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.
1.4 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

A12C
4
www.blaupunkt.com
the leak detection equipment being used is suitable for use
with flammable refrigerants, i.e. nonspeaking, adequately
sealed or intrinsically safe.
1.5 Presence of fireextinguisher
If any hot work is to be conducted on the refrigeration equipment or
any associate
parts, appropriate fire extinguishing equipment shall
be available to hand.Have a
dry powder or fireextinguisher adjacent to the charging area.
1.6 No ignition sources
No person carrying out work in relation to a refrigeration
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 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 sur rounding 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.
1.7 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

A12C
5
www.blaupunkt.com
the period that the work is carried out. The ventilation should
safely disperse any
released refrigerant and preferably expel it extremely into the
atmosphere.
1.8 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. lf in doubt consult the manufacturer's technical
department for assistance. The following checks shall be
applied to installations using flammable refrigerants: - 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

A12C
6
www.blaupunkt.com
components are constructed of materials which are inherently
resistant to being corroded or are suitably protected against
being so corroded.
1. 9 Checks to electrical devices
Repair and maintenance to electrical components shall
include initial safety checks and component inspection
procedures. lf a fault exists that could compromise safety, then
no electrical supply shall be connected to the circuit until
it is satisfactorily dealt with. lf the fault cannot be corrected
immediately but itis necessary to continue operation, an
adequate temporary solution shall be used.
•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.
Repairs to sealed components
2.1 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. lf it is
absolutely necessary to have an electrical supply to equipment

A12C
7
www.blaupunkt.com
during servicing, then a permanently operating form of leak
detection shall be located
at the most critical point to warm of a
potentially hazardous situation.
2.2 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 apparatus is mounted securely. Ensure that seals or
sealing materials have not degraded such 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 may inhibit the effectiveness of
some types of leak detection equipment. intrinsically safe
components do not have to be isolated prior
to working on them.

A12C

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.
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 sourcessuch as
compressors or fans.

Detection of flammablerefrigerants
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.
Leak detection methods
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 recalibration. (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 refrigerants

A12C
10
www.blaupunkt.com
but the use of detergents containing chlorine shall be avoided
as the chlorine may react with the refrigerant and corrode the
copper pipe-work. lf a leak is suspected, all naked
flames
shall be removed 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 detail. lt 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. lt is essential that electrical power is available
before the task
is commenced.
•Become familiar with the
equipment and its operation.
•lsolate system electrically.
•
Before attempting the procedure ensure that:
mechanical handling equipment is available , if required, for
handling refrigerant cylinders;

A12C
11
www.blaupunkt.com
all personal protective equipment is available and being used
correctly; the re covery process is supervised at all limes by a
competent person;
recovery equipment and cylinders conform to the appropriate
standards.
• Pump down refrigerant system, if possible.
•lf
a vacuum is not possible, make a manifold so that
refrigerant can be removed from various parts of the system.
•Make sure that cylinder is situated on the scales before
recovery takes place.
• Start the recovery machine and operate inaccordance with
manufacturer'sinstructions.
•
Do not overfill cylinders. (No more than 80 % volume liquid
charge).
• Do not exceed the maximum working pressure of the
cylinder, even temporarily
• When the cylinders have been filled correctly and the
process completed, make sure
that the cylinders and the
equipment are removed from sile promptly and all
isolation valves on the equipment are closed
off.
• Recovered refrigerant shall not be charged into another
refrigeration system un- less it has been cleaned and
checked.

A12C

www.blaupunkt.com
Labelling
Equipment shall be labelled stating that it has been
decommissioned 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.
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

A12C
13
www.blaupunkt.com
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 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.
lf compressors or compressor oils are to be removed, ensure that
they have been evacuated to an acceptable level to make certain

A12C
14
www.blaupunkt.com
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 toaccelerate
this
process. When oil is drained from a system, it shall be carried out
safely.
