14. Detection of flammable refrigerants

Under no circumstances shall potential ignition sources be used for searching or detecting refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used. Electronic leak detectors are acceptable for all refrigerant systems, but for FLAMMABLE REFRIGERANTS, sensitivity may be inadequate or require re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.)

Ensure the detector is not a potential ignition source and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and calibrated to the refrigerant employed, confirming the appropriate percentage of gas (25% maximum).

Leak detection fluids are suitable for most refrigerants, but avoid detergents containing chlorine as it may react with refrigerant and corrode copper pipe-work.

If a leak is suspected, all naked flames shall be removed/extinguished. If a refrigerant leakage requiring brazing is found, all refrigerant shall be recovered from the system, or isolated (by shut-off valves) in a remote part of the system. Refrigerant removal shall follow Removal and evacuation procedures.

15. Removal and evacuation

When breaking into the refrigerant circuit for repairs or other purposes, conventional procedures shall be used. For flammable refrigerants, best practice must be followed due to flammability.

The following procedure shall be adhered to:

• Safely remove refrigerant following local and national regulations.
• Purge the circuit with inert gas (optional for A2L).
• Evacuate (optional for A2L).
• Continuously flush or purge with inert gas when using flame to open circuit.
• Open the circuit.

The refrigerant charge shall be recovered into correct recovery cylinders if venting is not allowed by local/national codes. For appliances containing flammable refrigerants, the system shall be purged with oxygen-free nitrogen to render it safe. This process might need repetition. Compressed air or oxygen shall not be used for purging. Purging shall be achieved by breaking the vacuum with oxygen-free nitrogen, filling until working pressure is achieved, venting to atmosphere, and pulling down to a vacuum (optional for A2L). This process shall be repeated until no refrigerant is within the system (optional for A2L). When the final oxygen-free nitrogen charge is used, the system shall be vented down to atmospheric pressure for work.

The outlet for the vacuum pump shall not be close to any potential ignition sources, and ventilation shall be available.

16. Charging procedures

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

• Ensure contamination of different refrigerants does not occur when using charging equipment. Hoses/lines shall be as short as possible to minimize refrigerant contained in them.
• Cylinders shall be kept in an appropriate position.
• Ensure the REFRIGERATING SYSTEM is earthed prior to charging.
• Label the system when charging is complete (if not already).
• Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM. Prior to recharging, pressure-test with appropriate purging gas. Leak-test on completion of charging but prior to commissioning. A follow-up leak test shall be carried out prior to leaving the site.

17. Decommissioning

Before this procedure, the technician must be completely familiar with the equipment. It is recommended that all refrigerants are recovered safely. Prior to the task, an oil and refrigerant sample shall be taken if analysis is required before re-use of recovered refrigerant.

Electrical power must be available before the task commences.

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 for refrigerant cylinders.
• All personal protective equipment is available and used correctly.
• Recovery process is supervised at all times by a competent person.
• Recovery equipment and cylinders conform to appropriate standards.

d) Pump down refrigerant system, if possible.

e) If a vacuum is not possible, make a manifold so refrigerant can be removed from various parts of the system.

f) Make sure cylinder is situated on scales before recovery.

g) Start recovery machine and operate in accordance with instructions.

h) Do not overfill cylinders (no more than 80% volume liquid charge).

i) Do not exceed maximum working pressure of the cylinder, even temporarily.

j) When cylinders are filled correctly and process completed, ensure cylinders and equipment are removed promptly and all isolation valves on equipment are closed.

k) Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless cleaned and checked.

18. Labelling

Equipment shall be labelled stating it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure labels state the equipment contains FLAMMABLE REFRIGERANT.

19. Recovery

When removing refrigerant from a system for servicing or decommissioning, it is recommended that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure only appropriate recovery cylinders are employed. Ensure the correct number of cylinders for the total system charge is available. All cylinders must be designated for the recovered refrigerant and labelled for that refrigerant (i.e., special cylinders for refrigerant recovery). Cylinders shall have pressure-relief valves and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery.

Recovery equipment shall be in good working order with instructions and suitable for flammable refrigerant recovery. If in doubt, the manufacturer should be consulted. 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.

The recovered refrigerant shall be processed according to local legislation in the correct recovery cylinder, and the relevant waste transfer note arranged. Do not mix refrigerants in recovery units or cylinders.

If compressors or compressor oils are removed, ensure they have been evacuated to an acceptable level to ensure flammable refrigerant does not remain within the lubricant.

The compressor body shall not be heated by an open flame or other ignition sources to accelerate this process. When oil is drained from a system, it shall be carried out safely.
