● Never use sources of ignition when searching for refrigerant leaks. Do not
use a halide torch (or any other naked flame).
● For leak detection, the use of detergents containing chlorine must be
avoided.
● If a leak is suspected, all naked flames shall be removed/extinguished.
● Call the service agent immediately and keep far away from the product.
● If disposal is needed, please contact the service agent or authorised
personnel to do it. Do not dispose the product yourself.
● Install the appliance in accordance with national wiring regulations.
● The maximum refrigerant charge amount: 260g.
● Keep the appliance in a ventilated area. If there is a refrigerant leak, there is
less likely of a explosion or fire hazard happening.
● Check cords regularly, ensuring there is no damage, wear or corrosion.
● The following leak detection methods are deemed acceptable for systems
containing flammable refrigerants.
● Electronic leak detectors shall be used to detect flammable refrigerants, but
the sensitivity may not be adequate or may need recalibration (detection
equipment shall be calibrated in a refrigerant-free area).
● Ensure 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.
● If a leakage is found which requires brazing, all of the refrigerant shall be
recovered from the system, or isolated (by shutting off valves).
● Oxygen free nitrogen (OFN) shall then be purged through the system both
before and during the brazing process.
● Before carrying out this procedure, it is essential that the technician is
completely familiar with the equipment and all its detail. It is recommended
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
before reusing the reclaimed refrigerant. It is essential that electrical power
is available before the task is commenced.
● Become familiar with the equipment and its operation.
● Isolate system electrically.
● 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 adult.
– Recovery equipment and cylinders conform to the appropriate standards.

5
● Pump down refrigerant system, if possible.
● If a vacuum is not possible, make a manifold, so the refrigerant can be
removed from various parts of the system.
● Make sure that cylinder is situated on the scales before recovery takes place.
● Start the recovery machine and use in accordance with manufacturer’s
instructions.
● Do not overfill cylinders (no more than 80% volume liquid charge).
● Do not exceed the maximum working pressure of the cylinder, even
temporarily.
● When the cylinders have been filled correctly and the process completed,
make sure the cylinders and the equipment are removed from site promptly
and all isolation valves on the equipment are closed off.
● Recovered refrigerant shall not be charged into another refrigeration system,
unless it has been cleaned and checked.
● Label all equipment, stating that it has been decommissioned and emptied
of the refrigerant. The label must be dated and signed.
● Ensure there are labels on the equipment, stating it contains flammable
refrigerant. When removing the refrigerant from a system, either for servicing
or decommissioning, it is recommended that all refrigerants are removed
safely.
● When transferring the refrigerant into cylinders, ensure that only appropriate
refrigerant recovery cylinders are employed. Ensure 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
must be complete with a pressure relief valve and associated shut off valves.
Empty recovery cylinders are removed and, if possible, cooled before
recovery occurs.
● The recovery equipment must be in good working condition, 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 are available and are in good condition. Hoses shall be
complete with leak-free disconnect couplings and in good condition. Before
using the recovery machine, ensure it is in satisfactory working condition,
has been properly maintained and that any associated electrical components
are sealed to prevent ignition in the event of a leak. Consult the 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 removing compressors or compressor oils, ensure they have been
evacuated to an acceptable level, so the 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.

6
● Service shall only be performed as recommended by the equipment
manufacturer. Maintenance and repair operations requiring the assistance of
other skilled personnel shall be carried out under the supervision of the
person competent in the use of flammable refrigerants.
● Any person who is involved with working on or breaking into a refrigerant
circuit, should hold a current valid certificate from an industry-accredited
assessment authority, which authorises their competence to handle
refrigerants safely in accordance with an industry recognized assessment
specification.
