9. Troubleshooting
Information on servicing
1. 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,
the following precautions shall be
complied with prior to conducting
work on the system.
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.
3. General work area:
All maintenance sta 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 o.
Ensure that the conditions within the
area have been made safe by control
of flammable material.
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
the leak detection equipment being
used is suitable for use with flammable
refrigerants, i.e. non-sparking,
adequately sealed or intrinsically safe.

– 14 –
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
orCO2 fire extinguisher adjacent to the
charging area.
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 suciently 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.
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 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:
–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.
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
continueoperation, an adequate
temporary solution shall be used. This
shall be reported to the owner of the
equipment so all parties are advised.

– 14 – – 15 –
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.
Repairs to sealed components
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 isabsolutely
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
aected. 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 eectiveness of some
types of leak detection equipment.
Intrinsically safe components do not
have to be isolated prior to working on
them.
3. 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.
4. Cabling
Check that cabling will not be subject
to wear, corrosion, excessive pressure,
vibration, sharp edges or any other
adverse environmental eects. The
check shall also take into account the
eects of aging or continual vibration
from sources such as compressors or
fans.
5. Detection of flammable refrigerant
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.
6. Leak detection methods
The following leak detection methods
are deemed acceptable for systems
containing flammable refrigerants.

– 16 –
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 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. Oxygen free
nitrogen (OFN) shall then be purged
through the system both before and
during the brazing process.
7. Removal and evacuation
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 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 there is ventilation
available.
8. Charging procedures
In addition to conventional
charging procedures, the following
requirements shall be followed.
Ensure that contamination of
dierent 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

– 16 – – 17 –
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.
9. Decommissioning
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, forhandling
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 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.
10. Labelling
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.
11. 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 is available. All
cylinders to be used are designated
for the recovered refrigerant and

– 18 –
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 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 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.

to low-wind ventilation mode,
and maintain this state until the
drainage pipe becomes dry, so
as to keep the inside of the body
in a dry state and prevent it from
mildewing.
3. Turn o the machine, unplug the
power plug, and wrap the power
cord around the wrapping post;
install the water plug and the
drainage cover.
4. Remove the exhaust pipe and keep
it properly.
5. Cover the air conditioning witha
plastic bag. Put the air conditioning
ina dry place, keep it out of the
