Precautions for using R290 refrigerant

2

However, pay attention to the following points:

The basic installation work procedures are the same as the conventional refrigerant (R22 or R410A). 

CAUTION

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 minimised. 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 so as to minimise the
     risk of flammable gas or vapour 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.
