MAINTENANCE NOTICE

Qualification requirements of maintenance personnel

Inspection of the Site

Operating Procedures

Attention

:

For maintenance or scrap, please contact authorized service centers. Maintenance by unqualified person may 
cause dangers. Feed air conditioner with R32 refrigerant, and maintain the air conditioner in strictly accordance 
with manufacturer’s requirements. The chapter is mainly focused on special maintenance requirements for 
appliance with R32 refrigerant. Ask repairer to read after-sales technical service handbook for detailed information.

1.  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.

2.  The maintenance and repair of the air conditioner must be conducted according to the method 

recommended by the manufacturer. If other professionals are needed to help maintain and repair the 
equipment, it should be conducted under the supervision of individuals who have the qualification to repair 
AC equipped with flammable refrigerant.

Safety inspection must be taken before maintaining equipment with R32 refrigerant to make sure the risk of fire is 
minimized. Check whether the place is well ventilated, whether anti-static and fire prevention equipment is perfect.
While maintaining the refrigeration system, observe the following precautions before operating the system.

1. 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.

2.  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, Le.non-sparking, adequately sealed or intrinsically 
safe.

3.  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.

4.  No ignition sources: 

No person carrying out work in relation to a refrigeration 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.

5.  Ventilated Area(open the door and window): 

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.

6.  Checks to the refrigeration equipment: 

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