SAFETY PRECAUTIONS FOR R32 REFRIGERANT

• The interior of unit should be maintained by HVAC techs only.

• 1. Information on servicing

• 1.1 Checks to the area

• Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to ensure that the risk of

ignition is minimised. For repair to the REFRIGERATING SYSTEM.

• 1.2 Work procedure

• Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while the

work is being performed.

• 1.3 General work area

• All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined

spaces shall be avoided.

• 1.4 Checking for presence of refrigerant

• The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potential-

ly toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applica ble refrigerants,

i. e. non-sparking, adequately sealed or intrinsically safe.

• 1.5 Presence of fire extinguisher

• If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire extinguishing equip ment shall

be available to hand. Have a dry powder or CO

fire extinguisher adjacent to the charging area.

• 1.6 No ignition sources

• No person carrying out work in relation to a REFRIGERA TING SYSTEM which involves exposing any pipe work shall use any sources of

ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, inc luding cigarette smoking, should

be kept suf ficiently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possibly be

released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure tha t there

are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed.

• 1.7 Ventilated area

• Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A

degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrig-

erant and preferably expel it externally into the atmosphere.

• 1.8 Checks to electrical devices

• Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a faul texists

that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot

be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to

the owner of the equipment so all parties are advised. Initial safety checks shall include:

• that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;

• that no live electrical components and wiring are exposed while charging, recovering or purging the system;

• that there is continuity of earth bonding.

• 2. Cabling

• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental

effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

• 3. Detection of flammable refrigerants

• Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or

any other detector using a naked flame) shall not be used.

• The following leak detection methods are deemed acceptable for all refrigerant systems. Electronic leak detectors may be used to detect

refrigerant leaks but, in the case of FLAMMABLE REFRIGERANTS, the sensitivity may not be adequate, or may need re-calibration. (De-

tection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable

for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the

refrigerant employed, and the appropriate percentage of gas (25 % maximum) is confirmed.

• Leak detection fluids are also suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the

chlorine may react with the refrigerant and corrode the copper pipe-work NOTE Examples of leak detection fluids are

• bubble method,

• fluorescent method agents.

• If a leak is suspected, all naked flames shall be removed/extinguished.

• If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means

of shut off valves) in a part of the system remote from the leak.

• 4. Removal and evacuation

• When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However,

for flammable refrigerants it is important that best practice be followed, since flammability is a consideration. The following procedure shall

be adhered to:

• safely remove refrigerant following local and national regulations;

• purge the circuit with inert gas;

• evacuate (optional for A2L);

• purge with inert gas (optional for A2L);

• open the circuit by cutting or brazing.

• The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. For

appliances containing flammable refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for flam-

mable refrigerants. This process might need to be repeated several times.

• Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants, refriger-

ants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pres-

sure is achieved, then venting to atmosphere, and finally 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 to enable work to take place. Ensure that the outlet for the vacuum pump is not close to any potential ignition

sources and that ventilation is available.

• 5. 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 in an appropriate position according to the instructions.

• Ensure that the REFRIGERATING 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 REFRIGERATING SYSTEM.

• Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak-tested on comple-

tion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

• 6. Decommissioning

• Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recom-

mended 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 recovered refrigerant. It is essential that electrical power is available before the task is

commenced.

• Become familiar with the equipment and its operation.

• Isolate system electrically.

• 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.

• Pump down refrigerant system, if possible.

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

• Make sure that cylinder is situated on the scales before recovery takes place.

• Start the recovery machine and operate in accordance with instructions.

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

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

• 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.

• Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been cleaned and checked.

• 7. Labelling

• Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For

appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels on the equipment stating the equipment contains

FLAMMABLE REFRIGERANT.

• 8. 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 refrig-

erant 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 recov-

ery 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 all appropriate refrigerants including, when applicable, FLAMMABLE REFRIGEANTS. 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 com-

pressor 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.

• 9. WARNING FOR USING R32 REFRIGERANT

• Appliance shall be installed, operated and stored in a room with a floor area larger than 4 m².

• Appliance shall not be installed in an unvertilated space, if that space is smaller than 4 m².

• Compliance with national gas regulations shall be observed.

• The appliance shall be stored so as to prevent mechanical damage from occurring.

• Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate from an industry-

accredited assessment authority, which authorises their competence to handle refrigerants safely in accordance with an industry

recognised assessment specification.

• Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair requiring the assistance of

other skilled personnel shall be carried out under the supervision of the person competent in the use of flammable refrigerants.

• Please follow the instruction carefully to handle, install, clear, service the air conditioner to avoid any damage or hazard. Flammable

Refrigerant R32 is used within air conditioner. When maintaining or disposing the air conditioner, the refrigerant (R32) shall be recovered
