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.
