to the material objects for reference.
This appliance is not intended for use by persons (including children) with reduced physical, sensory
or mental capabilities or lack of experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

●The following checks shall be applied to installations using flammable refrigerants:
●Initial safety checks shall include:
●Checking for presence of refrigerant
●Repairs to sealed components
●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.
The Refrigerant
– 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.
– 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.
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.
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.

●Repair to intrinsically safe components
●Cabling
The Refrigerant
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.
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.
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.
●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.
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.

●Labelling
●Recovery
Equipment shall be labelled stating that it has been decommissioned and emptied of refriger-
ant. 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.
When removing refrigerant from a system, either for servicing or decommissioning, it is
recommended good practice that all refrigerants are removed safely.
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.
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 refriger-
ants including, when applicable, 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.
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.
The Refrigerant
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.
