Precautions for using R32 refrigerant

The basic installation work procedures are the same as the conventional refrigerant

(R22 or R410A). However, pay attention to the following points:

1. Transport of equipment containing flammable refrigerants

Compliance with the transport regulations

2. Marking of equipment using signs

Compliance with local regulations

3. Disposal of equipment using flammable refrigerants

Compliance with 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.

6. Information on servicing

6-1 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 minimized. For repair

to the refrigerating system, the following precautions shall be complied with prior

to conducting work on the system.

6-2 Work procedure

Work shall be undertaken under a controlled procedure to minimize the risk

of flammable gas or vapor being present while the work is being performed.

6-3 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 control of flammable material.

6-4 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.
