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 con-

   ditions 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 CO

2

 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;

WARNING

This symbol shows that this appliance 

used a mildly flammable refrigerant. 

If the refrigerant is leaked and exposed  

to an external ignition source, 

there is a risk of fire.

CAUTION

This symbol shows that the operation 

manual should be read carefully.

CAUTION

This symbol shows that a service 

personnel should be handling 

this equipment with reference 

to the installation manual.

CAUTION

This symbol shows that inform-

ation is available such as the 

operating manual or installation

manual.

Explanation of symbols displayed on the unit(For the unit adopts R32 Refrigerant only):

1.Transport of equipment containing flammable refrigerants

See transport regulations.

2.Marking of equipment using signs

See local regulations.

3.Disposal of equipment using flammable refrigerants

See national regulations.

4.Storage of equipment/appliances

The storage of equipment should be in accordance with the manufacturer's instructions.

5.Storage of packed (unsold) equipment

Storage package protection should be constructed such that mechanical damage to the equipment inside the package

will not cause a leak of the refrigerant charge.The maximum number of pieces of equipment permitted to be stored

together will be determined by local regulations.
