7. Connection piping installation
7.1 Installation precaution
Please choose the phosphorus deoxidation seamless copper pipe as the piping.
◇
If use the lengthen piping needs welding:
Please welding before fasten the nut, when welding using nitrogen gas to replace the air
in the pipe in order to prevent oxidation.
◇
If there are many points to be welded when installing the lengthen piping, please set a
filter in the pipe(buy from local market)
◇
Please use nitrogen gas or air to remove the dust and water in the pipe,
◇
Please lay out the piping according to the tend towards of the piping, but it is not allowed
more than 3 times curved at the same point of the pipe(if do like this the pipe will become
rigid)
◇
Pipe bending machine is used during the process of bending the pipe, the curvature shall
not be too small or it will affect the refrigerant flow.
