INSTRUCTIONS FOR REPAIRING APPLIANCES 

CONTAINING R290

GENERAL INSTRUCTIONS

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 refrige-

rating system, the following precautions shall be complied with prior to conducting work 

on the system.

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.

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.

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 tection equipment being used is suitable for use with flammable refrige

-

rants, i.e. nonsparking, adequately sealed or intrinsically safe.

Presence of fire extinguisher

♦ If any hot work is to be conducted on the refrigeration equipment or any associated 

parts, propriate fire extinguishing equipment shall be available to hand. Have a dry 

powder or CO 2 fire extinguisher adjacent to the charging area.

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 igarette 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.

Ventilated area

♦ Ensure that the area is in the open or that it is ade- quately 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.

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 mainte- nance 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 out

-

lets 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.

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.

REPAIRS TO SEALED COMPONENTS

♦

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.

♦ 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 flam

-

mable 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.

REPAIR TO INTRINSICALLY SAFE COMPO- NENTS

♦ 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 com- ponents only with parts specified by the manufactu

-

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

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.

DETECTION OF FLAMMABLE REFRIGE- RANTS

♦

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.
