SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when servicing an appliance with R32.
1. Area safety check
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to minimize the risk of ignition. Prior to repairing the refrigerating system, the following precautions
shall be complied.
2. Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of exposure to a flammable gas or vapor during the process.
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 conditions within the area have been made safe by the control of flammable material.
4. Checking for the presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during the work, to ensure the technician’s awareness of potentially flammable atmosphere. Ensure that the leak
detection equipment used is suitable for use with flammable refrigerants, i.e. no sparking, adequately sealed or intrinsically safe.
5. Presence of fire extinguisher
If any high-temperature operation is to be conducted on the refrigeration equipment or any of its 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
Don’t carry out work in relation to a refrigeration system that is exposed to any pipework that contains flammable refrigerant using any sources of ignition in order to avoid the risk of fire or explosion.
All possible ignition sources, including cigarette, should be kept far away from the site of installation, repairing, removing, and disposal. Prior to work, ensure that the surrounding area has no flammable
hazard or ignition risks, and the "No Smoking" sign shall be displayed.
7. Ventilated area
Ensure that the area is open or adequately ventilated before breaking into the system or conducting any high-temperature operation. Please keep ventilation during the process. The ventilation
should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
8. Refrigeration equipment check
When electrical components are being changed, they shall be suitable for the purpose and be aligned with the correct specification according to the maintenance and service guidelines. If you
encounter any problem, please feel free to consult the manufacturer 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.
