Presence of fire extinguisher

If hot work is conducted, have appropriate fire extinguishing equipment (dry powder or CO2 extinguisher) available.

No ignition sources

Do not use ignition sources when working on refrigeration systems. Keep ignition sources (including smoking) away from installation, repair, removal, and disposal sites. Survey the area for flammable hazards or ignition risks. Display 'No Smoking' signs.

Ventilated area

Ensure the area is open or adequately ventilated before breaking into the system or conducting hot work. Ventilation should continue during work to disperse refrigerant.

Checks to the refrigeration equipment

• Electrical components must be fit for purpose and specification. Follow manufacturer's maintenance and service guidelines.
• Checks for installations using flammable refrigerants:
• Charge size must be in accordance with room size.
• Ventilation machinery and outlets must be operating and unobstructed.
• If using an indirect refrigerating circuit, check the secondary circuit for refrigerant. Ensure markings are visible and legible.
• Refrigeration pipes/components should be positioned where they are unlikely to be exposed to corrosive substances, unless protected.

Checks to electrical devices

• Repair and maintenance must include initial safety checks and component inspection.
• If a fault compromises safety, do not connect electrical supply until it is resolved.
• If a fault cannot be corrected immediately but operation must continue, use an adequate temporary solution and report it.
• Initial safety checks include:
• Discharging capacitors safely to avoid sparking.
• Ensuring no live electrical components or wiring are exposed during charging/recovering/purging.
• Checking continuity of earth bonding.

Repair to intrinsically safe components

Do not apply permanent inductive or capacitance loads without ensuring they do not exceed permissible voltage/current. Replace components only with manufacturer-specified parts.

Cabling

Check cabling for wear, corrosion, pressure, vibration, sharp edges, or other adverse effects, including aging or vibration from compressors/fans.

Detection of flammable refrigerants

Do not use potential ignition sources (like halide torches or naked flames) to search for or detect refrigerant leaks.

Leak detection methods

Use electronic leak detectors for flammable refrigerants. Ensure detectors are calibrated, not a source of ignition, and suitable for the refrigerant. Leak detection fluids are suitable, but avoid those containing chlorine. If a leak is suspected, extinguish all naked flames. If brazing is required for a leak, recover all refrigerant or isolate the system. Use oxygen-free nitrogen (OFN) for purging before and during brazing.

Removal and evacuation

Use conventional procedures for breaking into the refrigerant circuit. Recover refrigerant, purge with inert gas, evacuate, purge again, and then open the circuit. Recover refrigerant into correct cylinders. Flush the system with OFN to render it safe, repeating as necessary. Do not use compressed air or oxygen. Flushing involves breaking vacuum with OFN, filling to working pressure, venting, and pulling a vacuum, repeating until no refrigerant remains. Vent to atmospheric pressure before brazing. Ensure vacuum pump outlet is not near ignition sources and has ventilation.

Charging procedures

Follow requirements to prevent refrigerant contamination. Use short hoses. Keep cylinders upright. Earth the refrigeration system before charging. Label the system upon completion. Do not overfill. Pressure test with OFN before recharging. Leak test after charging and before commissioning. Conduct a follow-up leak test before leaving the site.

Decommissioning

• Technicians must be familiar with the equipment. Recover refrigerants safely.
• Take oil and refrigerant samples if analysis is required for re-use. Ensure electrical power is available.
• Become familiar with equipment operation.
• Isolate system electrically.
• Ensure mechanical handling equipment, personal protective equipment, and recovery equipment/cylinders are available and used correctly. Recovery process must be supervised.
• Pump down refrigerant system if possible.
• If vacuum is not possible, use a manifold to remove refrigerant.
• Place cylinder on scales before recovery.
• Operate recovery machine per manufacturer's instructions.
• Do not overfill cylinders (max 80% volume liquid charge).
• Do not exceed cylinder working pressure.
• Promptly remove cylinders and equipment after filling, closing all isolation valves.
• Recovered refrigerant shall not be charged into another system unless cleaned and checked.

Labelling

Label equipment as de-commissioned and emptied of refrigerant, dated and signed. Ensure labels indicate the equipment contains flammable refrigerant.

Recovery

Remove refrigerants safely for servicing or decommissioning. Use appropriate recovery cylinders and ensure correct number are available. Designate and label cylinders for the recovered refrigerant. Cylinders must have pressure relief valves. Cool empty cylinders if possible. Recovery equipment must be in good working order with instructions and suitable for flammable refrigerants. Calibrated weighing scales and leak-free hoses are required. Check recovery machine is maintained and electrical components are sealed. Return recovered refrigerant to the supplier in the correct cylinder with a Waste Transfer Note. Do not mix refrigerants. If compressors or oils are removed, ensure they are evacuated to remove flammable refrigerant. Evacuate before returning compressors. Use electric heating to accelerate compressor body evacuation. Drain oil safely.

Gentle Reminder

Check the appliance regularly and refer to TROUBLESHOOTING or contact customer support if it shows any of the following signs:

• Power cord or plug is damaged.
