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.

9. Checks to electrical devices

15

ENG

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.

17. 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.

18. 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.

19. 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.

20. Detection of ﬂammable refrigerants

Under no circumstances shall potential sources of ignition be used in the searching for or detection of

refrigerant leaks. Ahalide torch (or any other detector using a naked ﬂame) shall not be used.

21. 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

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.

22. 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;

16

ENG

- 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.

23. 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;

- 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 onthe equipment are closed off.

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

checked.

24. 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.

25. 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. 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 all appropriate refrigerants including, when applicable,

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 recover 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.
