Safety precautions

Precaution for using R32 refrigerant

The basic installation work procedures are the same as conventional refrigerant (R410A, R22) models.

Since the working pressure is higher than that of refrigerant R22 models, some of the piping and installation and service tools are special. Especially, when replacing a refrigerant R22 model with a new refrigerant R32 model, always replace the conventional piping and ﬂ are nuts with the R32 and R410A piping and ﬂ are nuts on the outdoor unit side. For R32 and R410A, the same ﬂ are nut on the outdoor unit side and pipe can be used.

The mixing of different refrigerants within a system is prohibited. Models that use refrigerant R32 and R410A have a different charging port thread diameter to prevent erroneous charging with refrigerant R22 and for safety. Therefore, check beforehand. [The charging port thread diameter for R32 and R410A is 1/2 inch.]

Must always ensure that foreign matter (oil, water, etc.) does not enter the piping. Also, when storing the piping, securely seal the opening by pinching, taping, etc. (Handling of R32 is similar to R410A.)

•

Operation, maintenance, repairing and refrigerant recovery should be carried out by trained and certiﬁ ed personnel in the use of ﬂ ammable refrigerants and as recommended by the manufacturer. Any personnel conducting an operation, servicing or maintenance on a system or associated parts of the equipment should be trained and certiﬁ ed.

•

The user/owner or their authorised representative shall regularly check the alarms, mechanical ventilation and detectors, at least once a year, where as required by national regulations, to ensure their correct functioning.

•

A logbook shall be maintained. The results of these checks shall be recorded in the logbook.

•

In case of ventilations in occupied spaces shall be checked to conﬁ rm no obstruction.

•

Before a new refrigerating system is put into service, the person responsible for placing the system in operation should ensure that trained and certiﬁ ed operating personnel are instructed on the basis of the instruction manual about the construction, supervision, operation and maintenance of the refrigerating system, as well as the safety measures to be observed, and the properties and handling of the refrigerant used.

If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.

•

Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections, terminals not made to original speciﬁ cation, damage to seals, incorrect ﬁ tting of glands, etc.

•

Ensure that apparatus is mounted securely.

•

Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of ﬂ ammable atmospheres.

•

Replacement parts shall be in accordance with the manufacturer’s

speciﬁ cations. NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them.

4. Repair to intrinsically safe components

•

Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use.

•

Intrinsically safe components are the only types that can be worked on while live in the presence of a ﬂ ammable atmosphere.

•

The test apparatus shall be at the correct rating.

•

Replace components only with parts speciﬁ ed by the manufacturer. Unspeciﬁ ed parts by manufacturer may result ignition of refrigerant in the atmosphere from a leak.

6. Detection of ﬂ ammable refrigerants

•

Under no circumstances shall potential sources of ignition be used in the searching or detection of refrigerant leaks.

•

A halide torch (or any other detector using a naked ﬂ ame) shall not be used.

English

Safety precautions

7. The following leak detection methods are deemed acceptable for all refrigerant systems

•

No leaks shall be detected when using detection equipment with a sensitivity of 5 grams per year of refrigerant or better under a pressure of at least 0.25 times the maximum allowable pressure (>1.04 MPa, max

4.15 MPa), for example, a universal sniffer.

•

Electronic leak detectors may be used to detect ﬂ ammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection 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 conﬁ rmed.

•

Leak detection ﬂ uids are also suitable for use with most refrigerants, for example, bubble method and ﬂ uorescent method agents. The use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.

•

If a leak is suspected, all naked ﬂ ames 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. The precautions in #8 must be followed to remove the refrigerant.

8. Removal and evacuation

•

When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, it is important that best practice is followed since ﬂ ammability is a consideration. The following procedure shall be adhered to: remove refrigerant -> purge the circuit with inert gas -> evacuate -> purge with inert gas -> open the circuit by cutting or brazing.

•

The refrigerant charge shall be recovered into the correct recovery cylinders.

•

The system shall be purged with OFN to render the appliance safe.

•

This process may need to be repeated several times.

•

Compressed air or oxygen shall not be used for this task.

•

Purging shall be achieved by breaking the vacuum in the system with OFN and continuing to ﬁ ll until the working pressure is achieved, then venting to atmosphere, and ﬁ nally pulling down to a vacuum.

•

This process shall be repeated until no refrigerant is within the system.

•

When the ﬁ nal 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 potential ignition sources and there is ventilation available.

OFN = oxygen free nitrogen,

type of inert gas.

9. 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 minimize 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 over ﬁ ll the refrigerating system.

•

Prior to recharging the system it shall be pressure tested with OFN (refer to #7).

•

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.

•

Electrostatic charge may accumulate and create a hazardous condition when charging and discharging the refrigerant.To avoid ﬁ re or explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before charging/discharging.

10. Decommissioning

•

Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details.

•

It is recommended good practice that all refrigerants are recovered safely.

i) Do not exceed the maximum

working pressure of the cylinder, even temporarily.

j) When the cylinders have been

ﬁ lled 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 refrigerating system unless it has been cleaned and checked.

•

Electrostatic charge may accumulate and create a hazardous condition when charging or discharging the refrigerant.To avoid ﬁ re or explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before charging/discharging.

11. 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 ﬂ ammable refrigerant.

12. 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 are 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.

•

Recovery cylinders are evacuated and, if possible, cooled before 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 ﬂ ammable refrigerants.

•

In addition, a set of calibrated weighing scales shall be available and in good working order.

•
