Warnings(for using R290/R32 refrigerant only)
Extreme care shall be taken not to overfill 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.
14.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.
15.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
flammable refrigerant.
16.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 is 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 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.
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.
Note About Fluorinated Gasses
-Fluorinated greenhouse gases are contained in
hermetically sealed equipment. For specific information
on the type, the amount and the CO
2
equivalent in tonnes
of the fluorinated greenhouse gas(on some models),
please refer to the relevant label on the unit itself.
-Installation, service, maintenance and repair of this unit
must be performed by a certified technician.
-Product uninstallation and recycling must be performed
by a certified technician.
