3.4.2 General information on copper refrigeration pipes
C A U T I O N
•
The copper pipe used in the refrigeration installations is different to the copper pipe used in installations
carrying domestic or heating water.
•
The copper pipe for refrigeration installations is especially treated for outdoors and indoors. The interior
surface finish makes it easier for the gas refrigerant to circulate and withstands the action of the lubricant oil
applied to outdoor equipment.

3.4.4 Preparing and cutting copper refrigeration pipes
Preparation
Clean the area where the copper refrigeration pipe preparation work is to be carried out. It must particularly be free of waste,
soil, wood or metal shavings and, in general, any substance that could enter the ends of the pipe during handling.
The copper pipe must be clean and have no remains of adhesive, cement, dust or other substances adhered to it.
Where the copper pipe is supplied in rolls, fit a cap on the end and
unwind it while it is resting on the ground so that the turning
movement of the roll as it is unwound forms a straight pipe.
N O T E
•
The rolls of copper refrigeration pipe are normally supplied with caps on their ends.
•
Where the roll of pipe does not come supplied with caps, check that the inside of the pipe is clean. If it is not,
use a new roll of pipe.
