Repairing Appliances Containing R290

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 precaution shall be completed prior to

conducting work on the system.

2. Work procedure

Work shall be undertaken under a controlled procedure 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.

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 toxic or flammable

atmospheres. Ensure that the leak detection equipment being used is suitable for

use with all applicable 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 refrigerating 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 refrigerating 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, including

cigarette smoking, should be kept sufficiently 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 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 refrigerating 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.

REPAIR

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

• The actual refrigerant charge 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.

• Refrigerating 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

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 capacitor is discharged: this shall be done safely to avoid the 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.

10. Repairs to sealed components

During repairs to sealed components, all electrical supplies shall be disconnected

from the equipment being worked upon before any removal of sealed covers, etc. If

it is 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, an excessive number of

connections, terminals not made to original specification, damage to seals,

incorrect fitting of glands, etc.

Ensure that the apparatus is mounted securely.

Ensure that seals or sealing materials have not degraded to the point that they no

longer serve the purpose of preventing the ingress of flammable atmospheres.

Replacement parts shall be by the manufacturer’s specifications.

11. 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 currently permitted

for the equipment in use.

Intrinsically safe components are the only types that can be worked on while living

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.

12. 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 consider the effects of ageing or continual vibration from sources such as

compressors or fans.

13. 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.

14. 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, best practice must be followed since flammability 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. For

appliances containing flammable refrigerants, the system shall be purged with

oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This

process may need to be repeated several times. Compressed air or oxygen shall

not be used for purging refrigerant systems.

For appliances containing flammable refrigerants, refrigerants purging shall be

achieved by breaking the vacuum in the system with oxygen-free nitrogen 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 oxygen-free nitrogen charge is

used, the system shall be vented down to atmospheric pressure to enable work to

take place. This operation is vital if brazing operations on the pipework are to take

place.

Ensure that the outlet for the vacuum pump is not close to any potential ignition

sources and that ventilation is available.

15. 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 before 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.

Before recharging the system, it shall be pressure-tested with the appropriate

purging gas. The system shall be leak-tested on completion of charging but before

commissioning. A follow-up leak test shall be carried out before leaving the site.

16. Decommissioning

Before carrying out this procedure, the technician must be completely familiar with

the equipment and all its detail. It is recommended good practice that all

refrigerants are recovered safely. Before the task being carried out, an oil and

refrigerant sample shall be taken in case analysis is required before re-use of

recovered refrigerant. Electrical power must be available before the task is

commenced.

a) Become familiar with the equipment and its operation.

b) Isolate the 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 always supervised by a competent person.

• Recovery equipment and cylinders conform to the appropriate standards.

d) Pump down the 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 the cylinder is situated on the scales before recovery takes

place.

g) Start the recovery machine and operate by 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 the 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.

17. 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.

18. 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 a

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.

Also, 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 the 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 before

returning the compressor to the suppliers. Only electric heating to the compressor

body shall be employed to accelerate this process. When the oil is drained from a

system, it shall be carried out safely.
