6. Information on servicing
• 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 minimised. 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 minimise the risk
of a ammable gas or vapour being present while the work is being performed.
• 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 conned 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.
• 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 refrigerants, i.e.non-sparking, adequately sealed or
intrinsically safe.
• 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.
• 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 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 suciently 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.
• 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 t for the purpose
and to the correct specication. 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 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 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
• 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 aected. This shall include damage to cables, excessive number
of connections, terminals not made to original specication, 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 specications.
NOTE: The use of silicon sealant may inhibit the eectiveness of some types
of leak detection equipment. Intrinsically safe components do not have to be
isolated prior to working on them.
6
• 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 ammable atmosphere. The test
apparatus shall be at the correct rating. Replace components only with parts
specied 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 eects. The check shall
also take into account the eects of aging or continual vibration from sources
such as compressors or fans.
• Detection of 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.
• Leak detection methods
The following leak detection methods are deemed acceptable for systems
containing ammable refrigerants. Electronic leak detectors shall be used to
detect ammable 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 conrmed. 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 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.
• 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 ammability 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 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.
7
• Charging procedures
In addition to conventional charging procedures, the following requirements shall
be followed. Ensure that contamination of dierent 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 overll 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.
• 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, 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 overll cylinders. (No more than 80 % volume liquid charge).
i) Do not exceed the maximum working pressure of thecylinder, 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.
• 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 ammable refrigerant.
