available for refrigeration professionals to recycle

used refrigerants. More information may be

obtained from the refrigerant wholesalers.

•

NeverNever

Never use alcohol or other byproducts as a

solvent. They cause corrosion on the compressor

tubes and metallic parts and the electric

insulation becomes brittle.

• Only use filters with desiccants suitable for the

type of refrigerant (see table 2, Chapter VI).

4 - How to Clean a used

Refrigeration System

Not all compressor changes require cleaning the

low and high pressure tubes.

Cleaning is recommended in cases where it is

suspected that there are high levels of

contamination of water and residues resulting from

the burnout of the compressor winding. In these

cases:

In R 12 systems, you should make the actual R 12

or R 11, or the degreaser R 141b, or VERTREL XF

circulate when it is liquid.

In systems operating with R 134a, you may use the

R 141b degreaser or VERTREL XF for cleaning.

To protect the environment and reduce expenses

when changing compressors, fluid for cleaning the

unit's components must circulate in closed circuits.

At this stage when changing the compressor, the

return line shall be disconnected from the

compressor and the capillary disconnected from

the filter drier.
