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 overﬁll the refri-

geration 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 equip-

ment and all its detail. It is recommended good prac-

tice that all refrigerants are recovered safely. Prior to

the task being carried out, an oil and refrigerant sam-

ple 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 com-

menced.

a) Become familiar with the equipment and its ope-

ration.

b) Isolate system electrically.

c) Before attempting the procedure ensure that:

Mechanical handling equipment is available, is requi-

red, for handling refrigerant cylinders;

All personal protective equipment is available and be-

ing used correctly;

The recovery process is supervised at all times by a

competent person;

Recovery equipment and cylinders conform to the

appropiate 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 part 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 accor-

dance with manufacturer’s instructions.

h) Do not overﬁll cylinders. (No more than 80% volu-

me 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 clea-

ned and checked.

15. Labelling

Equipment shall be labelled stating that it has been

de-commissioned and emptied of refrigerant. The la-

bel shall be dated and signed. Ensure that there are

labels on the equipment stating the equipment con-

tains 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 appropiate refrigerant recovery cylinders

are employed.

Ensure that the correct number of 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 reco-

very cylinders are evacuated and, if possible, cooled

before recovery occurs.

The recovery equipment shall be in good working or-

der to 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 calibra-

ted 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 satis-

factory working order, has ben 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 re-

frigerant 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

and acceptable level to make certain that ﬂammable

refrigerant does not remain within the lubricant. The

evacuation process shall be carried out prior to retur-

ning 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 greenhose gases are contained in hermeti-

cally sealed equipment. For speciﬁc information on the

type, the amount and tje CO2 equivalent in tonnes of

the ﬂuorinated greenhose gas (on some models), plea-

se refer to the relevant label on the unit itself.

- Installation, service, maintenance and repair of this unit

mus be performed by a certiﬁed technician.

- Product uninstallation and recycling must be performed

by a certiﬁed technician.
