INSTRUCTIONS FOR REPAIRING APPLIANCES CONTAINING R290

1. Servicing

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, the following precautions shall be

complied with prior to conducting work on the system.

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.

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. The area around the workspace shall be sectioned off.

Ensure that the conditions within the area have been made safe by control of flammable material.

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 potentially flammable atmospheres. Ensure that the leak detection equipment being

used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

5) Presence of fire extinguisher

If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire

extinguishing equipment shall be available to hand. Have a dry powder or CO₂ fire extinguisher adjacent to the

charging area.

6) No ignition sources

No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that

contains or has contained flammable refrigerant 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, including cigarette smoking, should be kept

sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable

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 that there are no flammable hazards or ignition risks. “No Smoking”

signs shall be displayed.

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 refrigerant and preferably expel it externally into the

atmosphere.

8) Checks to the refrigeration equipment

Where electrical components are being changed, they shall be fit for the purpose and to the correct

specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt

consult the manufacturer’s technical department for assistance.

The following checks shall be applied to installations using flammable refrigerants:

– The charge size is in accordance with the room size within which the refrigerant containing parts are

installed;

– The ventilation machinery and outlets are operating adequately and are not obstructed;

– If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of

refrigerant;

– Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be

corrected;

– Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any

substance which may corrode refrigerant containing components, unless the components are constructed of

materials which are inherently resistant to being corroded or are suitably protected against being so corroded.

- 17 -

9) Checks to electrical devices

Repair and maintenance to electrical components shall include initial safety checks and component inspection

procedures. If a fault exists 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 there no live electrical components and wiring are exposed while charging, recovering or purging the

system;

• That there is continuity of earth bonding.

2. Repairs to sealed components

1) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being

worked upon prior to any removal of sealed covers, etc. 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.

2) 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 specification, damage to seals, incorrect

fitting 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 flammable atmospheres. Replacement parts

shall be in accordance with the manufacturer’s specifications.

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.

3. 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 flammable atmosphere. The test

apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer.

Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

4. 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.

5. 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.

6. Leak detection methods

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

Electronic leak detectors shall be used to detect flammable 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

- 18 -

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

fluids are 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. 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. Oxygen free nitrogen (OFN) shall then be purged through the system both before

and during the brazing process.

7. 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 flammability is a

consideration. The following procedure shall be adhered to:

• Remove refrigerant;

• Purge the circuit with inert gas;

• Evacuate;

• Purge again 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 “flushed”

with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or

oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with

OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally

pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the

final 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 ignition sources and there is ventilation available.

8. 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 upright.

– Ensure that the refrigeration 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 refrigeration system.

Prior to recharging the system it shall be pressure tested with OFN. 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.

9. Decommissioning

Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment

and all its detail. It is recommended 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

reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.

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, if required for handling refrigerant cylinders;

• All personal protective equipment is available and being used correctly;

- 19 -

• The recovery process is supervised at all times by a competent person;

• Recovery equipment and cylinders conform to the appropriate standards.

d) Pump down refrigerant system, if possible.

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

system.

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

g) Start the recovery machine and operate in accordance with manufacturer's instructions.

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

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

j) 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.

k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and

checked.

10. 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

flammable refrigerant.

11. 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

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. Empty 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 flammable refrigerants. 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 compressor 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.

Competence of service personnel

General

Special training additional to usual refrigerating equipment repair procedures is required when equipment with

flammable refrigerants is affected.

In many countries, this training is carried out by national training organisations that are accredited to teach the

relevant national competency standards that may be set in legislation.

The achieved competence should be documented by a certificate.
