GENERAL

- Pipe installation should be kept to a minimum.

AREA CHECKS

Before work is started on systems that recontains combustible refrigerants, safety checks must be performed to ensure that the ignition risk is kept to a minimum.

WORKING METHOD

The work must be carried out in a controlled way to minimise the risk of contact with combustible gas or liquid during the work.

GENERAL FOR THE WORKING RANGE

All maintenance sta and those who work in close proximity to the product must be instructed which type of work is to be carried out. Avoid carrying out work in enclosed spaces. The area surrounding the worksite must be cordoned off. Ensure that the area is made safe by removing combustible material.

CHECK FOR THE PRESENCE OF REFRIGERANT

Check whether there is refrigerant in the area using a suitable refrigerant detector prior to and during work, to notify the service technician whether there is a possible ammable atmosphere or not. Ensure that the refrigerant detector is suitable for combustible refrigerant, i.e. does not generate sparks or cause ignition in any other way.

PRESENCE OF FIRE EXTINGUISHERS

If hot work is carried out on the heat pump, a powder or carbon dioxide fire extinguisher must be to hand.

ABSENCE OF IGNITION SOURCES

Pipes connected to the unit must not con- tain potential sources of ignition.

Those who carry out work with refrigerant system connections, including exposing pipes that contain or have contained combustible refrigerant, may not use potential ignition sources in such a way that can lead to risks of re or explosions.

VENTILATED AREA

Ensure that the work is carried out outdoors or that the work area is ventilated before the system is opened and before any hot work is carried out. The area must be ventilated whilst the work is being carried out. There must be ventilation around any refa gerant that comes out, which should be routed outdoors.

CHECKING COOLING EQUIPMENT

If electrical components are replaced, the replacement parts must be t for purpose and have the correct technical specifications. Always follow the manufacturer's guidelines regarding maintenance and servicing. Contact the manufacturer's technical department in the event of any doubt

The following checks must be carried out for installations that use combustible refrigerants.

- The actual lling quantity is appropriate for the magnitude of the space where parts containing refrigerant are installed

- Ventilation equipment and outlet work correctly and without obstructions.

- If an indirect refrigerant circuit is used, check whether the secondary circuit contains refrigerant.

- All markings of equipment are visible at clear. Markings, signs and similar that a not clear must be replaced.

- Refrigerant pipes and components are positioned in such a way that it is not likely that they be subjected to substances that can corrode components containing refrigerant, if these components are not made of material that is distant against corrosion, or not appropriately protected against such corrosion.

temporary solution must be implemented. This must be reported to the equipment owner, so that all parties have been informed.

The following checks must be carried out at the initial safety checks.

That the capacitors are discharged. Discharging must be done safely, to prevent the risk of sparking.

That no powered electrical components or live cables are exposed when lling or collecting refrigerant or when the system is ushered.

That the system is continually earthed.

REPAIRING SEALED COMPONENTS

When repairing sealed components, all electrical supply must be disconnected from the equipment that is being repaired before any sealed covers or similar are removed. If it is absolutely necessary to have the electricity supply to the equipment during the service, continuously activated leak tracing must be performed at the most critical points in order to warn of any dangerous situations.

Pay particular attention to the following so that the sheath is not changed in a way that acts the protection level when working with electrical components. This means damage to cables, unnecessary amounts of connections, terminals that do not follow the original specifications, damaged gaskets, incorrect grommets etc.

Ensure that the apparatus is secured properly.

REMOVAL AND DRAINING

When a cooling circuit is opened for repairs - or for another reason- work must be carried out in a conventional manner. Due to the risk of re it is important that best practice is applied. Follow the procedure below.

WIRING

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental eects. The check shall also take into account the eects of aging or continual vibration from sources such as compressors or fans.

1. Remove the refrigerant
2. Open the circuit by cutting or brazing.

Collect the refrigerant in the intended cylinders.

LEAK TESTING

The following leak detection methods are deemed acceptable for systems containing ammable refrigerants.

Ensure that the vacuum pump's outlet is not near to any potential ignition sources and that there is satisfactory ventilation by the outlet.

Electronic leak tracers must be used to detect combustible refrigerant; but the leak tracer may not be sufficiently sensitive or may need to be recalibrated (the leak tracing equipment must be calibrated in an area completely free from refrigerant).

FILLING

In addition to the conventional lling procedures, the following actions must be taken.

leak tracer must not be a potential source. Ensure that dierent refrigerants are not of ignition and must be suitable for the re-mixed when lling equipment is used. evant refrigerant.

Mark the system once lling is complete (if not already marked). If the amount differs from the pre-installed amount, the marking must include the pre-installed amount, the added extra amount and the total amount.

If a leak is suspected, all naked ames sh be removed/extinguished.

- Take extra care not to overll the cooling system.

Before relling the system, pressure test it with oxygen-free nitrogen. Leak test the ^10 . system after lling but before using the system. Perform an additional leak test before leaving the installation.

DECOMMISSIONING

Before the device is taken out of operation the technician must without exception be very familiar with the equipment and all its component parts. Good practice prescribes that all refrigerant is collected safely. Be before the collected refrigerant can be reused, oil and refrigerant samples must be taken if analysis is required. There must be a power supply when this task is started.

1. Familiarise yourself with the equipment and its use.
2. Isolate the system electrically.

3. Before starting the procedure, ensure that:

4. necessary equipment for mechanical handling of the refrigerant container is available

5. all necessary personal safety equipment is available and used correctly
6. the collection process is continuous supervised by an authorised person

7. the collection equipment and containers meet appropriate standards.

8. Pump the refrigerant system to vacuum if possible.

9. If it is not possible to pump to vacuum manufacture a branch, so that the regerant can be retrieved from dierent parts of the system.
10. Check that the refrigerant container is on the scales before starting to collect
11. Start the collection device and collect according to the manufacturer's instructions.
12. Do not overll the containers (max. 80 % (volume) liquid content).

Do not exceed the containers' maximum permitted working pressure - not even temporarily.

When the containers have been lled correctly and the process is complete, close all shut-o valves in the equipment and remove and containers and equipment from the installation immediately.

The collected refrigerant must not be lled in any other system before being cleaned and checked.

Marking

The equipment must be marked stating that it has been taken out of operation and drained of refrigerant. The marking must be dated and signed. Check that the

equipment is marked indicating that it contains combustible refrigerant.

Collection

Best practice prescribes that all refrigerant is collected safely when the refrigerant is drained from a system, either for servicing or for decommissioning.

The refrigerant must only be collected in suitable refrigerant containers. Ensure that the required number of containers, which can hold the entire volume of the system, are available. All containers that are to be used must be intended for the collection of the refrigerant and marked for this refrigerant (specifically designed for the collection of refrigerant). The containers have to be equipped with correctly functioning pressure relief valves and shut-o valves.

Empty collection containers must be drained and, if possible, chilled before collection.

The collection equipment must function correctly and instructions for the equipment must be to hand. The equipment must be suitable for the collection of combustible refrigerant.

Fully functioning and calibrated scales must also be to hand.

Hoses must be in good condition and be equipped with leak-proof quick couplings. Before using the collecting machine, check that it is working correctly and has been properly maintained. Associated electrical components must be sealed, to prevent ignition if any refrigerant should leak out. Contact the manufacturer if you are in any doubt.

Return the collected refrigerant to the refrigerant supplier in the correct collection container and with the relevant Waste Transfer Note. Do not mix refrigerants in collection devices or containers.

If compressors/compressor oil are/is to be removed ensure that the aected device is drained to an acceptable level to ensure that no combustible refrigerant remains in the lubricant. Compressors must be drained before being returned to the supplier. Only electrical heating of the compressor housing may be used to quicken draining. Drain oil from the system in a safe manner.

MISCELLANEOUS

Maximum amount of refrigerant: See Technical Specifications in the Installer Manual.

• Everyone who works with or opens a refrigerant circuit must have a current, valid certificate from an accredited industry issuing body, which states that, according to the industry's recognised assessment standard, they have the authority to safely handle refrigerants.
• Servicing must only be performed according to the equipment manufacturer's recommendations.

Maintenance and repairs that require the assistance of another trained person must be carried out under the supervision of person with the authority to handle combustible refrigerants.

Maintenance and repair that requires the skill of another person must be carried out under the supervision of someone with the above expertise.
