cylinders. (No more than 80 % volume liquid charge). i) Do not exceed the maximum working

pressure of thecylinder, 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

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.

14.Decommissioning

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

13.Charging procedures

In addition to conventional charging procedures, the following requirements shall be followed. Ensure

that contamination of different refrigerants does not occur when using charging equipment. Hoses or

lines shall be as short as possible to minimise the amount of refrigerant contained in them.

Cylinders shall be kept upright.

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 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.

oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system

with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and

finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system.

When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable

work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take

place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is

ventilation available.

Installation

Instructions

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.
