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.
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.
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 extinguishing equipment shall be available to hand. Have a dry powder or
CO2 fire extinguisher adjacent to the charging area.
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.
Checks to electrical devices 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.
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 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.

Specialist’s Manual
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 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 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.
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 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 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 ad-
25
Specialist’s Manual
dition, 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.
