1.Checks to the area
Prior to beginning work on systems containing
ammable refrigerants, safety checks are necessary to
ensure that the risk of ignition is minimized for repair
to the refrigerating 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 minimize the risk of a ammable
gas or vapour being present while the work is being
performed.
2.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 conned 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 ammable material.
3.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 ammable
atmospheres. Ensure that the leak detection
equipment being used is suitable for use with
ammable refrigerant, i.e. non sparking, adequately
sealed or intrinsically safe.
4.Presence of re extinguisher
If any hot work is to be conducted on the refrigeration
equipment or any associated parts, appropriate re
extinguishing equipment shall be available to hand.
Have a dry powder or CO2 re extinguisher adjacent
to the charging area.
5.No ignition sources
No person carrying out work in relation to a refrigerant
system which involves exposing any pipe work that
contains or has contained ammable refrigerant
shall use any sources of ignition in such a manner
that it may lead to the risk of re 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 ammable 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 ammable hazards or
ignition risks.”No Smoking”signs shall be displayed.
6.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 wok. 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.
7.Checks to the refrigeration equipment
Where electrical components are being changed,
they shall be t for the purpose and to the correct
specication. 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 ammable refrigerants:
- the charge size 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
8.Checks to electrical devices
Repair and maintenance to electrical components shall
include initial safety checks and components 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 there no live electrical components and wiring are
exposed while charging, recovering or purging the system;
-that there is continuity of earth bonding
9.Repairs to sealed components
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.
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
specication, damage to seals, incorrect tting 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 ammable atmospheres, Replacement
parts shall be in accordance with the manufacturer’s
specications.
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.
10.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 components are the only types that can be
worked on while live in the presence of a ammable
atmosphere. The test apparatus shall be at the correct
rating.
Replace components only with parts specied by
manufacturer. Other parts may result in the ignition of
refrigerant in the atmosphere from a leak.
11.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.
12.Leakage detection for ammable 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
ame) shall not be used.
MAINTENANCE

A5P | 01
13.Leak detection methods
The following leak detection methods are acceptable
for systems containing ammable refrigerant.
Electronic leak detectors shall be used to detect
ammable refrigerants, but the sensitivity may not
be adequate, or may need recalibration (Detection
equipment shall be calibrated in a refrigerant-free
area.) Ensure that detector is not a potential source of
ignition and is suitable for the refrigerant used.
Leak detection uids 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 ames shall be
removed/extinguished.
If a leak of refrigerant is found which requires brazing,
all of the refrigerant shall be recovered from the
system. Oxygen free nitrogen (OFN) shall then be
purged through the system both before and during the
brazing process.
14.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”ushed”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 ll until
the working pressure is achieved, then venting to
atmosphere, and nally pulling down to a vacuum.
This process shall be repeated until no refrigerant is
within the system. When the nal 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 pipework are to take place. Ensure that the
outlet for the vacuum pump is not close to any ignition
sources and there is ventilation available.
15.Refrigerant 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
minimize 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 overll 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 commissioning. A
follow up leak test shall be carried out prior to leaving
the site.
16.Decommissioning
Before carrying out this procedure, it is essential that
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 reuse of
reclaimed refrigerant. It is essential that electrical power
is available before the task is commenced.
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 repaired,
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 overll 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 lled 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.
17.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
ammable refrigerant.
18.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 designed 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 value and associated
shut-o values 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
ammable refrigerants.
In addition, a set of calibrated weighing scales shall
be available and in good work 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
MAINTENANCE

A5P | 01
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 ammable 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.
19.Transport of equipment containing ammable
refrigerants.
Determined by local regulations.
20.Discarded appliances supplies ammable refrigerants.
See National Regulations.
21.Storage package (unsold) equipment
Storage package protection should be constructed such
that mechanical damage to the equipment inside the
package will not cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to
be stored together will be determined by local regulations.
