6. The Refrigerant Piping Construction

● Refrigerant R410A is used in the refrigerant circulation system. Do not allow oxygen, acetylene
or other flammable and toxic gases to fill the refrigerant pipe during leakage and air tightness
test. These gases are very dangerous and may cause an explosion. It is recommended to use
nitrogen.
● Ensure that there is no pressure inside the stop valve when removing the cap on the stop
valve.
Make sure that the refrigerant piping is connected in the same refrigeration system.

6.1 Piping Material

(1) Prepare copper pipe for on-site construction.
(2) Follow the instructions in Table 6.1 and Table 6.2. Select the copper pipe specifications.
(3) Choose clean copper pipes. Make sure that there is no dust and moisture inside the copper pipe
inner wall. Before performing piping connection, use dry air or nitrogen to blow the inside of the
copper pipe to remove internal dust or impurities. Do not cut the copper pipe with tools such as
saws and grinding wheels that can produce metal debris.
